Was This the First Rainboom?

"Without the mane six, equestria would probably be doomed"
Described the season 5 finale in one sentence

I don't feel like Rainbow Dash was ever the first one to pull a sonic rainboom. I feel like it was an unknown Pegasus from a long time ago. So long, everyone thought it was a legend. But I don't think it was Rainbow Dash's family or ancestors. It could of been a different Pegasus.

For an event that was altered in time like, 20 times, I can fully believe that RD's first boom moment would have become noticed by those that can see the future. Not often you might see the same event that many times with slight changes. That would be worth writing down as a prophecy.

I found out this mares tale. "When the legend of the Rainboom is fulfilled, the bearers of the elements shall have their mark of destiny, and after 16 years they shall meet, and Nightmare Moon they shall defeat."

i have a theory. so rainbow dash was the first to do a sonic rainboom. there is a theory that twilight IS clover the clever. that she went back in time. what if she wasn't the only one to go back, and rainbow dash performed a sonic rainboom somehow or something. this would explain why its called the sonic rainboom cause if any pony else did it they would make it look different and so, not be called the sonic rainboom. who knows maybe more of the mane 6 also went back in time? what do you think about that theory?

Perhaps Celestia could pull off the sonic rainboom? Being the oldest Alicorn (With rainbow hair I might add) it is not unbelievable that she could pull off the downright legendary feat. However it is doubtful that she would use it often. She wouldn't use it in combat as she is likely more effective concentrating on magic. She wouldn't use it on ordinary travel as she goes by chariot. In fact the only times I can think of that she could and would have used the rainboom is during the first two episodes as she needed to move quickly and avoid contact or capture. Also it fits with the move's mythical status as Celestia has let several other major events fade into legend.

It’s Probably the first one ever properly documented and seen by others


Just a thought.....

I think one of Rainbow Dashes great-great-great-great-great ancestors must have been the first one to the sonic rainboom because

1: a mares tale must be pretty old

2: how does Rainbow get her rainbow-colored mane/hair

3 FROM HER ANCESTORS

like if you agree

maybe someone in Rainbow Dash's family pulled off a Sonic Rainboom

Not only did she prove it true, She did it 4 times in her life (disregarding the fanfic Double Sonic Rainboom); The 1st as a filly, the 2nd in Sonic Rain Boom, the 3rd in Lesson Zero destroying Applejacks barn, and the 4th in A Canterlot Wedding Part 2.
I believe she's not the 1st one to perform it, but rather a descendant of someone who has.

This might be a stretch but I think it was Flash Magnus, he is a sort of predecessor to rainbow and as rainbow said “he could outfly dragons”. Dragons that were depicted as the same size if not larger than ember’s father, so imagine their wingspan

I like the "magical destiny" theory and it goes well with RD literally being rainbow-colored, as if it's what she was made for.
My first instinct was theory 2, but even in 2019, the only candidate we have for that is Flash Magnus, and he didn't show the same flight capabilities as RD.
I don't think theory 1 would work, though, simply because science doesn't usually become legend that way.

My theory :

Long long ago when pegasi first contoled the weather a mischevios young fill was playing near the construction cite of the rainbow factory . Every day she would come after school to look at it . Her bwst friend then dared her to go inside one evening. As she flew in her wings got caught as she fell in rainbow water . Sge suddenly fell thew the floor and plumited towords the ground .






Seconds before she hit the gdround she pulled up and the rainbow water made a sonic boom. A few ponys saw this including star swirl.







That is my theory .

I always had the feeling that LUNA did the first one who did the first rainboom but it's not just a head cannon,if sonic rainboom is connecting to nightmare moon it's to Luna too and no only that,I think sonic rainboom happened way before celestia vanished luna to the moon but like some day before that...please someone think about it:Luna were over jealous of Celestia and she wanted to do something that ponies wouldn't forget,but instead of ponies amazed they scared of this big sound that sonic rainboom does and they hate her more, but after luna's vanished they thought of it as a legend and a super cool legend and in the episode twilight tried to teach rainbow about the story of wonterbolts she said "After Luna's vanished the protecting levels fail" and the one who actually did the rainboom must be brave enough to protect equestria with her sister but Celestia protecting Equestria alone they did have her strong magic but not Luna's pegasus power and this explain why on the Luna eclipsed Luna were controlling a cloud to prank rainbow at the finale
Edit: Yes i know alicorns have pegasus magic since we have seen Celestia and Twilight sitting and walking on clouds too but a part of my theory is that Celestia and Twilight can't CONTROL what a cloud will do and it makes sense being 2 pegasus born princesses (Luna and Cadence) and two unicorn born princesses (Twilight and Celestia) As we know Twilight was canon unicorn and take a look on a young Celestia toy (witch is a unicorn too) and also look at the stained glass on mlp g5 witch has a blue pegasus on WITCH IS SRSLY LUNA THERE THE SAME PONY JUST LOOK AT IT! Maybe a little while before she become an alicorn? And also the cloud thing + that it may represent the night and day : Pegasus and Unicorns are diffrent but can be together as night and day.
Does all this make sense?

Holy shit. Watching this after Season 5 finale, I have a new respect for you. The fact that the sonic rainboom was prophecy is pretty much confirmed now, as without it, Equestria turns out to be a warzone, an insect kingdom, a demon's playground and a barren wasteland. That last one brings some really interesting questions, as they cycled through all of the villains, so we can assume that the next baddie is extremely powerful. More powerful than anything we've encountered yet, as with all the other futures, there is, at least, something.

2:57 When Rainbow Dash saved Raratie from falling down the sky she pulled of the one and only RAINBOOM! I think she actually was the first pony to pull it of! Ya’ know why?... because there was an air push of because of Rainbow’s 🌈 speed. I think she was the first pony to do a sonic Rainboom and no pony else! Maybe they actually explained it as a Scientific explanation, a pony never did it so the other pony’s sed it was a legend, Years later Rainbow Dash proofed them rong!!

This video is really old but if you remember back in the Season 4 Premiere, Celestia used the Elements of Harmony on Luna and once she was banished to the moon, a Sonic Rainbom appeared, the Mare in the Moon was considered an old mare’s tale even though it’s been 1000 years, whose to say that this couldn’t be said the same for the Sonic Rainbom?

The third explanation was awesome! That is definitely the best reason why.

I think Star Swirl made up the theory of the rainboom, and behind the tribes, he befriend a fellow powerful pegasus to try and pull of the job, but didn't make it. When Star Swirl died, all his work and theories were all published for everypony to appreciate and the rainboom was taken in account as a myth, considering Star Swirl didn't prove it possible.

I think it was a prophecy. How else would the mane 6 get their cutie marks at the same time, an alicorn is made, and the 6 help friendship prohlems?!

You know, i like idea 2 the most, and i'm surprised you didn't use clips from the other season 1 episode with the sonic rainboom. In that episode Rainbow dash says "It's not just rare it's nearly impossible" or something to that effect. Suggesting that anyone who believes in the rainboom like rainbow obviously would, probably knows who had done it before.

Now here's a thought, what if i could say i know who said pony was. Well, I actually think i do, and it's probably kind of cliche, but hear me out. Princess 'Sunbutt' Celestia herself. It would make sense on both a fannon and cannon level. Firstly alot of fans like the idea that Spitfire would have her own varation of the rainboom, which given your own episode about it being magical would make sense, if she matched rainbows speed her own magical energy would not make a rainbow but more likely something that looked like a flame. Many fan ponies including one of my own have their own version of the rainboom, which are, when well written, usually fitting their character, and are usually weaker. Alot of fan allicorns also are able to reach this speed, which is not a stretch, as Allicorns are suppose to be really strong compared to the shorter lived species.

However, it also makes sense in cannon. Think about this, With all of the powers of the princesses Twilight was clearly the single most powerful being in all of equestria, but she never truly used it to it's fullest extent for very long. She restrained herself for most of it, and you want to know what, that girl shot across the distance between canterlot and ponyville in no time. If not for her attempt to restrain herself, she probably could of Magic Boomed. This is heavily shown in the fact that her fight with Tirek was pretty intense. Infact if she had been pegasus and not unicorn prior to the fight, it wouldn't surprise me if one of her major attacks had been to literally Fly right into her foe at top speeds. However she used all that power in magic based attacks because that's who Twilight is.

While the fandom has always liked pink haired celestia pre elements it's been confirmed that the rainbow flowing mane has basically always been Celestia's design, so what if, when she was alot younger, or just less restrained, Celestia flew at her top speeds just for fun like rainbow did, and given her design and magic, Created the first Rainboom? It certainly wouldn't be that odd for her to create a rainbow patterned ring with her aura, and we know the princesses liked to do things that would be kind of insane to most people as entertainment.

I always went with the second theory, that some legendary Pegasus or Alicorn made a rain boom prior or even at the beginning to the sisters rain.

Well when I saw this I compared it to how we humans believe dragons exist. since there is no proof they exist (like the dinosaurs) we think the mind most likely made it up. So that kinda supports the prophecy theory you had which I actually agree on. :3

One of RD's relatives could have caused the first Rainboom, one with a rainbow main, but none of those ponys from that time are around anymore so no one would be around to tell if it was true or not, hence classifying the Rainboom as a made up story.

I would think creating the sonic rainboom as a filly would have been the first time Equestria was subjugated to such awesomeness! 🌈

I have a theory that Celestia may have preformed a rainboom before Rainbow dash. If you look at scene where Celestia banishes Nightmare moon, what looks like a rainboom appears from the moon. This could be just an effect of magic like the purple flames created by Twlight's magic explained in his other video "How does the rainboom work". But maybe the speed of the blast that reached the moon in like 2 seconds was so fast it created a rainboom.

ITS HEAVILY IMPLIED WHEN STARLIGHT GOT BACK IN TIME TO STOP THE RAINBOOM THAT THE DISASTERS OCCUR IF IT DIDNT HAPPEN

Tie this into the theory of Twilight being clover the clever. If she went back in time maybe she wrote about the sonic rainboom but since no one in that time seen it, it would have been passed off as a legend instead. But the legend was so..........legendary and was passed down to the present.

I think the most plausible explanation is the Scientific theory or the prophecy.

What I think could be the case is that millennia ago, one of RD's ancestors could've pulled it off. This would explain how RD can pull it off, and explain why it's a "mare's tale"

I think I found why the sonic rainboom was legendary if you see at the season 4 ptemier in the flash back of the banishment if Nightmare Moon, when the elements of harmony sent her to the moon a sonic rainboom can be seen.Maybe that's were it got its legendary popularity.

I like the starswirl theory because now we know that he and the pillars are responsible for the tree of harmony, the elements and the connection between the mane 6. Which maybe why a sonic rainboom was responsible for bringing them together - starswirl's magic(not himself cos he was in limbo) is responsible for the sonic rainboom that dash performed.

the prophecy one seems plausible, i mean in the season 5 finale starlight went to stop the rainboom, and by now we all know how that turned out, implying the rainboom's importance

Hey sawtooth when celestia banished luna into the moon there was a rainboom she banished her soooooo fast that the rainboom happened so maybe this is the main reason why the rainboom is a legend since it was thousand years ago

Rainbow MIGHT have been the first, if she travelled back in time. One of your other videos tell that Twilight might have time-traveled to become Clover. What if there was a time problem(EQG, Twilight said she was stuck in a time loop for a long time, probably days). What if some other main six stuck with her? Rainbow, Applejack, or others? If Rainbow did travel back in time, it might lead to shoestrap paradox, where origin of Rainboom name and feat has no start.

I think dashie WAS the first one to do the sonic rainboom,according to ink rose's idea of dashie's background story her father was not only a racer but he also liked writing books mostly about a similar pony version called daring do

your idea about it being part of a prophecy makes the most sense in all honesty. I really enjoy watching your videos.

Hey, here's a possible theory on the 1st rainboom, when Princess Luna gets sent to the moon do you remember seeing that kind of 'rainboom' look? Maybe one pony saw this sight and told a bunch of other ponies what they saw but most ponies thought it was just a story but the ponies who believed it maybe passed down the legend, telling it as a bedtime story to young Pegasi and such. Then Rainbow dash proved the legends true. Anyone else agree with me, or am I just rambling nonsense?

My head cannon is somewhere in option #2 except instead of it happening thousands of years ago the event took place without any witnesses. So the validity of the event was not called into question because of time but because of the lack of evidence behind it. One pony saying "No guys! I swear I did it!!" is not enough to keep the idea around as fact for very long.

both the first and third option could be connected. if it was a prophecy maybe it was talking about a Pegasus that could cause a sound so loud it shocked everyone who heard it. also in the same prophecy it could say something about the same Pegasus with a rainbow following them. thus making a sonic rainboom.

My theory on it is that Luna was the first pony to do the sonic rainboom. She did it over 1,000 years ago and it became a folk tale. This actually takes less away from RD's accomplishment as before this no pegasus had ever done one.

Technically if it was new magic, RD should have ascended to alicorn status when she did it as a filly. Personally I think she was robbed.

I think what actually happened is when Celestia banishes Nightmare Moon, you can see there is a rainbow ring after she lands on the moon. I believe this is what started the story

My explanation of the rainboom:
Destiny doing its thing.
A rainbow seems to be a symbol of friendship to the ponies. The rainboom is what caused the friendship of these ponies. See the connection? The rainbow of the rainboom was made to draw the attention of the ponies. The rainboom probably happened in the past, used for other ponies to become friends, but long enough ago that's it's just a story. Could it possibly be the ancestors of the main 6? Could they help form equestria? Leave a like on this comment and comment down what you think!

I would like add a fourth theory to your rainboom ideas. You're a fan of Dr. Hooves. It's possible that he could have gone back at one point and let something slip, therefore creating a legend. Just an idea.

I haven't seen the video yet. But the flight formation "The Sonic Rainboom" was at least made before Rainbow Dash performed the Sonic Rainboom. Not the actual Sonic Rainboom but just the formation. It is said in Rainbow Dash's official Wonderbolts Academy Handbook which has some history on the Wonderbolts that "Commander Easyglider" Who was first mentioned in "Testing, Testing, 1, 2, 3" that he: "established classic Wonderbolts choreography with such famous moves as the 'Chevron Formation', the 'Incaranian Sun Salutation', and the memorable 'Sonic Rainboom'." So while its not directly said that he performed the actual "Sonic Rainboom" he did make the flight formation that Rainbow Dash used to pull it off in the episode "Sonic Rainboom". It would make sense that Commander Easyglider had made the formation to build up as much speed as possible. But he/she was never good enough at flying that he/she could pull off a magic nova like the Sonic Rainboom. And Rainbow Dash ended up being the first pony to fly so fast that it made an actual Sonic Rainboom..

I think both variants have sense. It can be that long time ago there was the pony colored like Rainbow Dash and who was a good flyer. And of course, it can be that Rainboom was just a theory.

really like the idea of the 2nd one, cause i feel it possible a pony has a simalar cutiemark to rainbow dash, i mean obovusly with how long ago it was, imagin in the old time rainbow were rare since in those time a pony had to do it since they didn't have ther fancy factories. it just that old tradition was forgotten kinda like how the windagoes are treat like a story and nothing more. if it wasn't part of a holiday how likely would ponies know about them?

When twilight did her special part in the summer sun celebration in season 4 episode 2 at the end was that a spell or a sonic boom?

hey guys, ever noticed what happend when Luna/Nightmare Moon was first banished to the moon? (in the season 4 opener) A RAINBOOM! do you think it's important for this video?

I think the prophecy would go something like this "The young filly was defending her fellow pony from bullying, a race was put on, the young filly flew up and behind her was a Sonic rainboom. As she flew her blank flank glowed, she had her cutie mark. And with her Sonic rainboom five other fillies had gained there's."

I know this is a pretty old vid but here's my theory :The rainboom was prophesied long before just like nightmare moon because in my opinion we have seen tons of proof that the rainboom was prophesied long ago and later remembered the prophesy as a old mare tale similar to night mare moon's.Originally it was prophesied and then known as a old pony tale of not that much importance. Similarly this could have happened with the rainboom.It is after all the most plausible theory to me at least....

actually, at the start of season 4, when Celestia banished nightmare moon to the moon, it caused a sonic rainboom. maybe thats where the prophecy stemmed.

When Discord was defeated by Celestia and Luna using the elements, there was a sonic rainboom. That was a thousand years ago if I’m correct.

This is my theory : Rainbow Dash was The first one to pull off the rainboom but she really wasn’t a scientific theory scientist discovered Mayor Pegasus that did the rain boom thousands of years ago she was an à Alcorn she casted a spell while doing the sonic rain boom that connected the main six of the last elements of harmony together well she casted a spell it granted five lucky elements from the three tribes together they all got there cutie mark at that same time the rain boom came even the Alcorn she was born an Alcorn so she had The power to make that magic of the sonic rain boom

Somehow I think the second explanation is the most like answer to the question of this video. Somehow I think maybe the First Rainboom was performed by a Pegasus during the Three Tribe Era and maybe that Pegasus was Rainbow's earliest ancestor.

I like your reasons but my theory is that if you are right and twilight is clover the clever then in some possible way twilight could have revealed the First Rainboom and thus sprouting a huge argument of wether or not it happened

Wait, I thought that Dashy could pull it off because her mane was rainbow-colored, too. The second theory doesn't follow this, unless the first pony to pull it off had a rainbow mane. Right?

If this was the 1st rainboom, wow! 👏
A few minutes later...
"Let's give a round of applause to Rainbow Dash for winning the world olympic record!" (If you get what I mean...)

I believe that now, with the s5 finale, the last theory is the most likely

i agree with ScareCr3w,Swettie Bloom,Maximum Mayhem,xPixelMeGamerx,iloveowls90,Bonnietelo Cole,Gwen Skulls,Forest Grump,Noel Klich,Christian Smith, & Natalie Hinman's theories & or comments. but i gotta say, that i totally agree with all you're guys's theories about one of rainbow's relatives doing a sonic rainboom long ago.

I honestly think it was an older relative of Rainbow Dash's who did the first rainboom. Because whenever anyone is going at a speed really fast their tail color is what shows as they zoom. And since it's called the" "Rain"(rainbow) boom, someone with a rainbow tail had to have done it for it to even be a legend. Cause it could've been the Grayboom if someone with a gray tail did it. So it must've been a person with a rainbow tail. So an older relative of Rainbow's who did the first rainboom in the past really does make sense. And in a case Rainbow may have inherited a special gene that allowed her to do it. This trait may have died out for the past generations in Rainbow's family until she was born. I mean her cutie mark practically says it all too.

What about when Celetia banished Luna to the moon. A blast almost identical to the sonic rainboom occured when this happened. So, doesn't that mean there can be more than one way of making a rainboom?

I like third explanation the most

I have a theory!
How did the other ponies know that rainboom is real?

Rainbow Dash seems to gain her speed and agility from her parents,ancestors etc.So just a head Canon probably one of her ancestors had pulled off a rainboom and as you said,prophecy...so probably the ancestors pulled off that rainboom that caused a harmony with his/her friends? And that's how rainbow dash pulled one that's important?

Focus on your studies more than your channel. As a High school graduate and a college sophomore I can safely say that your senior year will be the toughest of your grade school years and requires much of your attention. Uploading a video every other week can be a good solution to keeping you channel up to date. I will throw the suggestion out there to you to upload a video either at the end of your day on Friday or in the morning on one of the weekends. This way you can devote the work week to your studies. It will only get harder from here, but I know you'll do just fine. :) /)

I don’t think the lore requires raindash to be the first, just that the bearers of harmony would coincide with a rainboom

I think it’s was a prophesy. The Rainboom was an important part to bring the Mane Six together. Without it Equestria would have been under the control of the evil villains. So it’s important enough to have a prophecy about. That’s what I think 🙂🙂🙂

I would love to see an mlp episode about this.

Star swirl the bearded could have wiped up a spell that lifted him up, and he could have done one.

I'm glad to see your priorities are straight. School's far more important than entertaining us.

P.S. I might have to see if I can come up with a good fic about the first rainboom. I'll let you know if I do.

I love your intro, I love your OC, I love your videos, I LOVE YOUR CHANNEL!!!

I believe one of Rainbow's ancestor did the rainboom! And nobody believed her/him, so it was known as a fairy tale, until Rainbow Dash did it.

Hi TBN! I have a few questions:
1. Why is Pinkies family the only know family that has a last name (Pie)? 2. Are there human versions of the elements? My sister thought that RD had an element (at EGH), and said it was the belt she wore, and pinkie's was the ballon earrings. She asked me if she was right, and what the other human versions of the elements were, but I don't know. 3. Is Starswirl really dead? Did he take new life on the form of the Shadow Pony? If so, why'd he become evil all of a sudden? Where has he been all these years? If not, who IS the shadow pony?
Hope I didn't ask too many questions, but they really perplexed me, and I would appreciate if you helped me figure this out. Bring out! ^ ^

I think RD started the Sonic Rainboom. She does after all have Rainbow in her name. It's logical if you say it was RD's Dad, because he also has a rainbow mane. I think RD created the first Sonic Rainboom. Idk, that's all that I could think of.

Focus on your studies, they are most important especially your senior year. A video once a month will be enough for us fans who understand. Enjoy your senior year of high school, you're gonna miss being there once you're out. I'm 23 now and I miss the simplicity of high school. /)

One of your theories said that clover the clever was actually Twilight sparkle so when twilight back in time as clover the Clever she could have found someone one like as fast as Rainbow dash to perform the Sonic rainboom in the past

Actually in season 4 when celstia banshed Luna to the moon and there was a rainboom kinda thing formed

I also found out another theory that I think will go very well with this story in the olden times a mayor did this boom the last six got there cutie mark I was your destiny they met 16 years later they defeated a great evil became history/ this is the same theory that. Happened in the show The mayor tail is that once Every six years six Lucky Folls Would get their mark of destiny and then 16 years later they would have to defeat night mare moon I would be connected as not only as equestrians heroes but Also Friends

i believe that ponies thought of this a mares tail, but it was proven before. ponies have forgotten about the fact it has happened before. rainbow dash was a colt when she pulled it off. the rainboom could be a 'story' passed down so she will work hard. but the fact still remains that only rainbow dash was the only one we KNOW by the show was able to pull it off. the reaction of the other ponies every time she does the sonic rainboom shos that ponies really do think it was just a mares tail, proven true.

I think Rainbow ISN'T the first pony to pull off a sonic rainboom. I also think Rainbow Dash is a descendant of the first to pull off a sonic rainboom. Think about it: If Rainbow Dash is a descendant of the first pony to pull off a rainboom, their skills could be passsed down until they got to Rainbow! It's just that nopony in her family had go e that fast since that pony until their great great great great great great great great great great great granddaughter, Rainbow Dash!

I think the rainboom proves that there is a magic element to pegisi their flight and walking on clouds after all Tearak did steal flight.

I like how it's prophesied like you said Nightmare Moon was thought to be an old mares tale or made up prophesy that was real

I think Rainbowdash is a descendant of the pony who achieved the first rainboom. Seeing as her father has a rainbow mane, perhaps that aspect of a pony helps with making a rainboom... well RAINBOW.

Something that is making me curious is that did the elements of harmony connecta the main 6 or was it the rainboom and their cutie marks i think you'll need to watch season 4 and 5 endings to understand what i mean

Rainbow was the first. She’s always the winner 💁‍♀️

I've got a theory as well, even if its late, maybe, Rainbow wasn't the first one to pull off a sonic rainboom, maybe someone related to her from the olden days? Maybe that's why only she knows about it?

its funny that you mentioned the significance of the rainboom considering the end of season 5 :)

I personally think that the prophecy is the most likely one to be cannon due to past prophecies in the show, the whole thing about it being a scientific theory makes the most sense and the one about rainbow dash not being the first seems unlikely due to how well many events appear to be documented in equestria, especially something as big as that.

What if Sonic Rainbooms are different...
I mean Rainbow Dash made it "rainbow". But in one episode Twilight did it too. It was purple and pink not rainbow.

This was NOT the first rainboom if you see s1 ep1 you see that when Celestia banished Nightmare Moon, to the moon there was a rainboom.


this is my theory

Turns out it was celestia to do a rain boom because she old enough to be in a mares tail and she has great wing power and magic could help her too

I think your right about it being a scientific theory and rainbow unknowingly proved and since they didn’t know that it would happen it was a mares tail

I actually like the first explanation

I think you're going the best way because if the first pony was say for example Derby so she would fly so hard and fast 💨 you wouldn't believe your eyes 👀 maybe she was practicing flying by 📚 she would become the fastest pony in ponyVille but rainbow dash is

I think the concept of sonic rainboom was created by them just the way we thought of unicorns,fairies and the concept of magic

If you have time after studies maybe you could do more videos and in my opnion I believe that it is the third, sense Ranibow said about the legend and each leyend has it's own prophecy

Rainbow dash might have made the whole rainboom thing reality. Now hear me out! In the return of starlight glimmer. Twilight goes back in time to the day when rainbow pulls of a sonic rainboom for the first time and rainbow thinks the rainboom thing is a silly old tale but the point is... It was a silly story passed on by generation until surprise rainbow dash pulled it off. Rainbooms look a lot like rainbow's cutie mark and her name and hair color kind of goes to show that rainbow is a very special pony for the history of rainbooms!

It makes sense that she wasn't the first, I mean, genetics

The real questions we should be asking is when,where,why, and who predicted the prophecy?

I think that if someone did it before rainbow dash, it would be gusty the great, that sounds reasonable, right? It wouldn't be a full rainbow, but it would probably be at least multiple colors, after all I don't think that grogar would want to depict her in any flattering light.

Maybe Starswirl studied pegasi magic and gave theory about sonic rainboom but no pegasi who lived in his time managed to fly with such high speed, so theory became just a theory and noone thought it's true to the point when Rainbowdash actually proved theory to be true

With the season 5 finale it makes sense that the rainboom should be profisised

+The Brony Notion
If you have seen the recent episode "Rarity Investigates" you would know there is a character named "Wind Rider" who broke a record in the Mustang Marathon. Then Spitfire said "Rainbow Dash might actually beat his record" which is implying that Wind Rider was faster than Rainbow Dash at one point. Please make a video about this and if you do, shout out for my theory??? Thx

I like the prophecy fulfilled Theory also PS thank you for the Trek pun I'm a huge Star Trek and that made my day also no Rainbow Dash was so not the first one to pull it off and on another note you know how you were talking about that Alicorn civilization well maybe other Alicorns came in disguise as normal ponies Earth ponies pegasi unicorn and one of them pulled off a Sonic Rainboom or sonic magic boom because I mean come on yeah yeah

The prophecy explanation is a more...logical explanation. For example, the prophecy might have said something about a loyal and determined Pegasus, and an intervention with speed and magic.

Oh, theroy 2 suits me! As 4 ze pony who did the real first S.R.B. It was my fan pony, Wind Feather!

I believe that the Rainboom was a prophecy and that RD was the first to pull it off.

I hope your senior year is awesome!

Actually Rainbow did the rainboom first. When she was a filly. Back then no one know what a rainboom is. After Rainbow did it that’s when it become a mare tail. And she brought it back in season 1 ep 16.

"Without the Mane 6, Equestria would be DOOMED."

Oh boy, that phrase didn't aged well!! Like, AT ALL 😂😂😂😂

I think rainbow dash was the first ever pony to do the rainboom! [and btw this is the story of how she did it] so one day rainbow dash when she was a filly she went to the race, and she was in the lead when suddenly... WHOOSH! she flew off the track down towards the ground, and she was so fast that she made a ring of rainbow that was created by velocity [with flutter shy doing the same thing accept she got with animals] and then rainbow dash flew up into the air and then she just fell the end... hope you like this fan theory about yo question [ vuo / winky face] [does jay winky face voice]

In the cutie re-mark, twilight goes back and tries to talk to rainbow dash telling her to do a sonic rain boom. What if someone else from the future had went farther back in time and perhaps got stuck there and started telling stories? On of which was about the “first sonic rain boom” by rainbow dash. So she was actually the ones in the old mare’s tails if that makes sense

2:16 he explains last episode of season 5

"Without the main six Equestria would be doomed" little does he know he's right about everything...

I think the option that Rainbow Dash wasn't actually the first to pull of a rainboom is the most logical one. I don't think a scientist would be able to convince enough ponies that their theory is right, scientists have hard time in magical worlds. As for the prophecy, now that the show is officially over I can safely say that there is no prophecy regarding the mane 6, otherwise we would have heard about it.
But if somepony else did the rainboom before, why is it called rainboom and not purpleboom or whatever the pegasus' color was? Well, it's not THAT crazy to assume there were rainbow-maned pegasi before RD. After all her father has it and so does Rainbow Blaze. And it wasn't necessarily a rainbow mane! It could have been anything colorful enough to look like a rainbow of sort. I personally like to think the first rainboom was red, yellow and blue, just like RD's cutie mark.

I know when and how it happened:Dashie's dad!Because well,if you've seen her Dad's cutie mark...you get the point.

What if the pillars like star swirl and that group came together because of the first sonic rainboom? Does that make sense

Thank you tablet for notification. I hope if you can't keep up at least once every other week try at least once a month so you have more time to focus on school. I think school is important. Just saying 😁

Rainbow Dash was the first to pull up a sonogram boo the person who thought sonogram bone was fake they made a sonogram boom up but then Rainbow Dash came in and did a sonic rainbow which makes sense because it actually doesn’t make it the person who made the sonogram boom tell a lie

My theory: long time ago, I don't think rainbow dash didn't pull the sonic rainboom , I think it was rainbow's great great great grandpa

Or maybe; not

Maybe some pony made the Rainboom up as a bedtime story, but then Rainbow Dash actually proved the impossible and the unthinkable by pulling it off

my theory is that some scientists or star swirl the bearded came up with the mare tale by using science he said it was possible but maybe no one was ever able to do it because they werent able to go as fast or they gave up another theory is that its like a rumour it might have been something different and somepony twisted it then another on and another until it went to the sonic rainboom

if dashie hadnt done the sonic rainboom the mane six wouldn't have been brought together, mane six woudnt be new barriers of the elaments of harmony,elements of harmony (and finishing a powerful spell,which might I add could have not only switched destiny's but destroyed equestria) wouldn't have a princess of friendship and princess of friendship wouldnt discover's human world because sunset shimmer won't get a crown cause twilight wouldn't have one seeing as to she'd need to be a princess and the crown signify's her royalty so add it all up and it just makes sense that rainbow dash is the main character

Well in the first 40 seconds you are already wrong. Before in the episode in Ponyville after rainbow dash crashed into the library one of the other mane 6 mention that rainbow dash has already done it when she got her cutie mark. This was the rainbow the other mane 6 saw in the episode when they discover their cutie marks are connected.

in the music video "Let the rainbow remind you" the elements make a rainbow. So i think in past all rainbooms is the elements of harmony' work.

I feel like the Rainbow boom was formed by one of Rainbow Dash's long long long long ago relative so she's not the first one and also that only if you have rainbow hair you probably could not pull it off but that's just another theory

the rainboom was first in the show caused by elements of harmony because at the scene were celestia banishes luna to moon using elements a same rain boom was happened

I bet rainbows dad did the Rainboom. His mane is exactly like Rainbow Dashes hair except shorter. Maybe he was friends with Twilight's parents and same with the others. Maybe if he didn't do the Rainboom he wouldn't have met them, and probably Twilight Velvet wouldn't have met her husband. Therefore Twilight wouldn't have been born, made into Celestia's School for Talented Unicorns, wouldn't have moved to ponyville, wouldn't have made friends, and Nightmare Moon would have won. So it was probably her father who did the Sonic Rainboom. What do u think of my idea? Plz reply.

I like the prophecy explanation it makes the most sense

ok, so what i noticed about fairy tails, is the name "fairiy tail" implys becuase it is a myth, becuase fairys do not have tails. however, the ponies do have tails, so that means annny myth that show puts on as a "mares tail" is possible to be true

Maybe star swirled the bearded theorized it and then hired someone to do it and it failed but then rainbow dash actually pulled it off

No. It couldn't be. The Rainboom is described as "And Old Mare's Tale." Meaning the Rainboom is older than Rainbowdash. Which means someone had to do it before Rainbowdash.

That means thay got there cutie Mark at the same time!!!

It could of been celestia so i disagree with the theory of it being before the sisters reign

I don't think rainbow dash was first because if you think about it the rumours about it would not be so accurate to the actual thing so there must have been someone before her to have done it so the facts on what it looked like and how hard it is and much wing power they needed could be accurate

Beware: I did not correctly stucture my ideas











what about this? Their has been heavy use of past actions be it legends, winter's holiday, star swirled, the map that can transport them to the past, the episode with a twilight from the future. Is it possible instead from establishng the future, they may expand the past? Let us say twilight and her freinds goes back, maybe a villion maybe a quest, as the map's main goal is to exist to preserve order. As it existed even when twilight's past had changed, but in that reality the tree of freindship has not expanded into a mansion. The map should not have been their, and wasnt their according to applejack, so is their more to the founding of the tree? Why does it have powers that can overcome the changing of history as it can appear without any clear reasoning? It must be before the formation of the kingdom of luna and celestia as they were unaware of the mansion and the true extent of the powers. It may lead to the travels with star swirled as their should be some sort of origin for the tree of harmony and he is the only pony with any merit(be it that he is the only pony of the past we have heard pleanty of) to accomplish such a task.




I am curious about discord as his nature opposes the idea of harmony. Could it be, if he was star swirled, a correlation to the alicorn amulet? He might have been intrested in dark magic, AE Alicorn magic(Aware that some how dark magic(the form and display)when overcomeing rarity, is similar to how alicorn magic was used on the potion) as he has lead to the creation of a spell that turned twilight into a alicorn. He may be someone intrested in the study of it and might have been involved in the creation of the alicorn amulet.

I think rainbow dash was the first one to pull of the sonic rainboom because who else can do that, only somepony who is 20% cooler and has a really serious need for speed in my opinion Everypony just assumed that a sonic boom is real and when rainbow dash did it, it became a sonic rainboom

“4 years ago” he’s still uploading videos in 2020

My brother has this theory that rainbow dash's dad (he can be seen in equestria games season 4) first performed the sonic rainboom as a filly like rainbow dash did and that's how it became a mare's tail but I'm not sure how old rainbow dash's dad is or how old something has to be to be called a mare's tail.

The first option is not correct because if it was a science theory the dialogue would have said the theory is proven to be true BUT It said The LEGEND is proven to be true.
Why had they said leyend if it was a theory?

I think it's a scientic theory, made by Star Swirl the Bearded.

if you are going to do other shows please do gravity falls it has a lot of mystery around it and with your therious i'll come to love the show even more

It could be that star swirl the bearded traveled to the future and saw rainbow dash perform the sonic rainboom and then he named the boom cased by rainbow dash the sonic rainboom and since star swirl the bearded goes way back ponies they must have passed it on as a mares tale

If the sonic rainbow was discovered before rainbowdash, it couldnt be her who made it true. Face it, we will never know who or whatever creature discovered it.

If you look into it you see that the Sonic Rainboom was actually only shown when Dash's friends were in danger when dash was trying to prove herself as the best of the best. This shows her element of 'loyalty' staying true to her element resulted in a sonic rainboom. It wasn't about the speed or anything numerical or factual but instead it was about the feelings of devotion and loyalty to her friends and choosing them over her dreams. It's just a theory though

I think the third one is correct well done sorry I was so hard on you in "How Do Ponies Get Their Names"! :(

The brony notion: “face it with out the mane 6 equestria will be doomed”
Me:😂😂😂😂😂😂😂😂😂😂😂😂

Or maybe when Celestia pulled the Sonic Rainboom when she banished Luna to the moon 1000 years ago, she saw that Rainbow Dash would pull off the Sonic Rainboom again in the future after that and convinced everypony that it is just an old mare's tale

If she was the first one to do it, How would they know it existed?

Maybe a really ancient relative of Rainbow Dash pulled it off before her? One with the rainbow colours? I Don' think we've been told much about Rainbow's family. Then it was passed down through the family until Rainbow finally did one?

why would you think the scientific theory is disapointing. I would totally go with the first explination.

rainbow dash wasn't the the first one with make the rainbow actually it was rainbow dash is father from its DNA rainbow dash was able to do the Sonic rainbow

the old mares tale could have been brought up when twilight goes back in time.

The first rain boom story kinda sounds like Amilia Earhart the first woman to fly a plane

If Rainbow s'rainboom is the first rainboom,then how the "legend of rainbooms" could be invented?

I think that the third one is true although seeing a fanfic on the second one would be cool ( I'm looking at you Rose Ink )

I got an equestrian girls ad before watching ☺️

I figure she’s the first in a REALLY long time.

It's ok, schools important :) we support u and good luck man! :D

could it be that when twilight sparkle went back to become clover the clever, rainbow dash was commander hurricane and pulled off the sonic rain boom. Rainbow dash would not know about it because she has not gone back in time yet.

Holy shit, I'm older than senpai?!

When celestia sent night mare moon to the moon there was a rainbow thing that looked like a rain bow so maybe that is the first rain boom

I would like to point out that if there was another pony that preformed the rainboom before rainbow dash I believe that this ponies mane would have to be rainbow in color otherwise it wouldn't be a rainbow rainboom

I know it's been like three years but I think rainbow dash was ment to be the one to be able to do the rainboom because she has rainbow in her and no one else does other than celestia

In The Episode Twilights Kingdom when the Princess's have given Twilight their Magic she performs a Sonic Rainboom except its not Rainbow its the colors of her mane.

Thanks phone for telling me about the new video (:

What about the potion twilight created in "double rainboom"? couldn't somepony else created it a long long time ago, the pegasus which drunk it would have performed a sonic rainboom, but was never able to do it again. there was only only one sonic rainboom before by the work from unicorns and pegasi together. That was before the princesses, while the seperation. because of the separation nopony really believed it would work, and after it was possible only once before rainbow dash, it went to be a legend.

I have a theory of rainbows hair. Her ancestor had a red mane and married a pony that had orange hair. Their child could have a red a orange mane, and maybe it just kept adding?

I have a question, are you gonna do the "Random videos!" series where you post videos about random shows and theories and reviews, I would appreciate that

I think It was Great x2 Grand Parents who did the trick, rainbow dash got her genetic hair off her dad, so then either RD's dad's dad or mum had the hair last, genetics get passed on and If RD's farther passed on his hair to RD, then he must have got it passed on to him

PEOPLE! Rainbow dash did a sonic rain boom when she was “a little filly”. I he first one was years ago

I think I've found it out people put it as a fairy tale but maybe the parents of Luna and clestia found it out but no one can pull it of because no one was fast enough to so they knew about but couldn't pull it off because no one was fast enough, Rainbow Dash is the first but they put it as a tale when it wasn't! possible?😏

if dashie hadnt done the sonic rainboom the mane six wouldn't have been brought together, mane six woudnt be new barriers of the elaments of harmony,elements of harmony (and finishing a powerful spell,which might I add could have not only switched destiny's but destroyed equestria) wouldn't have a princess of friendship and princess of friendship wouldnt discover's human world because sunset shimmer won't get a crown cause twilight wouldn't have one seeing as to she'd need to be a princess and the crown signify's her royalty so add it all up and it just makes sense that rainbow dash is the main character

well my theory is that rainbow dash is not the first pony to do the rainboom. I think that it was one of the two princess sisters since they are the oldest ponys. so they must have made up the rainboom for it to actually be true. but then what if it was made for evil purposes, like what if discord made it or tirek. you see, not every "good" thing has to be made from the side good.so thats my theory, please tell me if one of these is what YOU believe

is it just me or would Ink Rose and The Brony Notion make an adorable couple

I Know A Theory That's Why They Call SonicRainboom A Prophecy Because If It Weren't For Rainbow Dash's SonicRainboom There's No Mane Six And If Rainbow Dash Didn't Pull A Sonic Rainboom Equestria Will Be Doomed And Remember That The Mane Six Got Their Cutiemark At The Same Time Even If They Didn't Know Each Other Except For Fluttershy And Thats My Theory

Off topic and out of date. But does anyone know why pharynx was the only purple changeling?

Have you watched S5 EP25&EP26? The Rainboom is the most powerful and important force

Yes rainbow was the first to pull off sonic rainboom, but she wasn't the first to pull off the Concept if that makes any sense.

Rainbow wedash would not have been the first 1 to do a rainboom because how would pony's know what it is unless a pony like Starswirlbearded magically created it or a scientist figured a scientifically way to get a sonic boom and a rainbow all at the same time!

"I'm looking at you, Ink Rose." XD

I think you are right I think commander hurricane might have made the first rainboom but I feel like a pony with rainbow hair should only be the one who makes the first rainboom 🤔🤔

Well... Haven't you noticed rainbow dash's father also has rainbow mane ? I think he could also be one of the ponies who made it before rainbow Dash.

I like the idea that it was prophesied.

What if an Alicorn made the first rainboom?




What if nightmare moon did?

Wow, you’re confident for being in high school.
Also do you get teased for being a brony?
Also Also love you vids😊

Maybe it was Rainbow Dash's Ancestors that her family hadn't heard from after this ancestor made the first sonic rainboom and didn't know anything about this relative... Just a guess

The sixth element is twighlight and she’s purple in the rainbow and the rainbow is upside down so sometimes twighlight is the worst but most of the time she is #1 this might explain why twilight is the leader or it’s just because her element is magic. that’s just a small theory hope it makes sense

I swear she was the first ever pony to do the double sonic rainboom I'm probably wrong but oh well

DO STEVEN UNIVERSE CONTENT, ID EVEN DRAW YOU A GEM OC IF YOU DECIDE TO DO IT!!!


If u wanna see how it would look, my deviantart is IzzyFizz96.

I think this is the first rainboom, but not the first boom of sonic magic. I am sure twilight can do a sonic magic boom and celestia can sun beam boom and Luna can moon beam boom ,windy whistles can sonic cheer boom and lighting dash can go boom durring a stunt lol, but get my point?

I like theory 2 and I think my OC, Swirling Moon, did the first R.B.

I like theory 2 and I think my OC, Swirling Moon, did the first R.B.

Actually the elements of harmony created the first rainbow and Celestia use it to banish nightmare moon a rainbow appeared in her to the moon

I like them in this order

1: prophesy
2: SCIENCE
3: rainbow not first

I like prophesy best :)

no, its not because in the episode where starlight goes back in time, rainbow says "thats only a pony tale." meaning that it had happened before, a LONNNNNNGGGGGG time ago.

Ok so
Ranbow dash was the first to make a rainboom that was a RAINBOW somepony else could have made one that was colors that matches them, like ranbow dash match's the ranbow colors.

i dont think so.I think rainbows ancestors mostly have done the rainboom..So as the generations passed it passed mostly on rainbow..This is my opinion:))

OMFG MAKE A VIDEO ABOUT THE NEW MOVIE!

2:30 Actually, without Rainbow Dash, Equestria would be doomed. Does this mean Rainbow Dash is best pony? No, just most important.

the scientific theory was the most believable seriously that's what I'm sticking to😑

if you are watching this late 2015 then you know about the season 5 finale and how the main 6 really do matter to the fate of equestria

Don't judge me if I get this wrong it could be Celestia. How do I know? Well she could make legends come true like Nightmare Moon's trap and escape. I bet Celestia started off as a pegasaus. (Did I spell this wrong?) I bet she saw a stained glass with a rainbow art. She must've tried it. I also know this because she had been around for a long time. I also thought what ever is stained glass, will make it a mare's tale. But this is my theory so don't judge me. :)

i think that WITHOUT rainbow dash the 6 would not be the 6

I know im a bit late for this and you have maybe made a video about it but dash could be the first one to make a sonic rainboom because like zombies and vampires, where did those "stories" come, how do we know about zombies or vampires if they dont exist or never have so its possible to rumor about a sonic rainboom and then dash would be the first one to make it.

So what if even before Luna in Solo‘s there was boring there was a sonic rain boom she was a beautiful rainbow headed mayor and then she got c killed but her spirit was still going when she heard about the next Sonic rain Boomer she quickly try to get that from her shadow and raise her as her own in a shadow no one knew she was there so there was other ponies who did the sonic rain boom but they just were all extinct

Maybe somepony in the three tribes like inventor started to find magic in the Pegasus and after like all that research he/she tried to make a Sonic Rainboom and maybe other ponies makes like fun of him/her and someponies believed so it became a legend and then Rainbow Dash made the unpossible happen! This is my theory. It's just a theory, ok? Xd

my theory is that all large burst of magic result in a rainbow color or purple because they represent magic more than other colors

_' bruh u spelled prophecy wrong

In the book 'Elements of Harmony' it says Rainbow was NOT the first one.

I'm a girllllllllll not a bro :P
XD

Anyway I think that she pulled it off and then people later where led to believe it was just a legend. In one of the episodes, Rainbow's childhood bullies told her she could never do it as it was just a legend. They of course were proven wrong and even became "friends" I guess.

Edit: I was thinking maybe if they were the closest fillies, how could they not believe it was true? They forgot, meaning they just thought it was a legend. Also, if Rainbow Dash wasn't the first, how come no one else could ever do it? When she said "..they thought it wasn't possible.." (or whatever she said) then perhaps she was talking about right at that moment, no one would believe the NEW legend was true.

Edit2: Also did they even have colors/colours at that time??

Also, not only did the Rainboom bring the ponies together, it actually helped hatch Spikes egg.

Hope ur amused
It's just some news

It's only a theory anyway,
I actually have no idea
Guess i will find out another day?
Well I could read the comments down here ⬇

Here is my theory,when I saw that video you made named "How Does the Rainboom Work? And then my thought was this, so the sonic Rainboom was a pony's tale but I think that rainbow dash was the 2nd pony to do a sonic Rainboom in the episode that rainbow dash made a sonic Rainboom I realize that the Rainboom had a rainbow color but I think it was just from rainbow dash's mane or hair if you say and then in the past I think the only rainbow colored hair can do a Rainboom and maybe rainbow dash's great great great great grandfather or grandmother is the 1st pony in equestrian history because there is no pony I saw on the episode's that had a rainbow colored hair, and that's my theory I hope that's good for all of you guys.

I don't think rainbowdash was the first to do a sonic rainboom but it was along time since somepony did it, ponies stopped believing until rainbowdash did it.

i think rainbow dash dad was the first one to make the sonic rainboom

well i dont think rainbow dash is the firat pony to do the sonic rainboom because in season 5 in one episode spitfire says that rainbow dash could even beat a record of a colt so that means that colt already did some sort of sonic ranboom

well i dont think rainbow dash is the firat pony to do the sonic rainboom because in season 5 in one episode spitfire says that rainbow dash could even beat a record of a colt so that means that colt already did some sort of sonic ranboom

Sawtooth 2015: I'm gonna make different videos for different non-pony related things!

Sawtooth 2020: PONY THINGS. PONY THEORIES. POMIES!

I believe that the rainboom was a pridiction cause just like you said without the mane six Equestria is DOOMED clover the clever told star swril about the unity between the three Tribs which made him think about the alicorns thing have any of you guys saw the movie Avalon high where miles can predict what's about to happen. at end of the movie he is dressed in a clocky outfit similar to clover the clever which makes sense right?maybe clover the clever pridicted about the rainboom and maybe when the two sisters were little I suppose star swril thought that it has to happen as clover the clever pridicted it and just a thought he had made more pridictions which came true so like I almost said star swril thought making an elements of harmony can help and gived a huge amount of his power and when the two sisters were all grown and luna became jealous when celestia had use the elements of harmony as we saw in an episode the rainbow covered nightmare moon from bottom to top and when celestia used the elements nightmare moon waved her horn to make a spell and broke the element of magic and without the element of magic all the other elements broke too which went in to the future element of magic which was standing near as when zecora told twilight to look in the past and when she came back all the other element's magic went in to their places and the future always affects the past right? and this why the mane six are very important to Equestria

Who has watched bill nye

How long is a pony lifespan because the princesses ruled for a long time and how did Luna breath on the moon for 1000 years?

My theory:the editors don’t care
My second theory:somepony else say one and passed it round untill it was a story

Time travel possible in MLP what if Star Swirl the bearded used time travel to see it to see the rain boom and right it back and the science behind it was theorized

what if when rainbow-dash was younger performed it but everybody was so caught up in themselves and did not see it so when they felt it either they could of been in a building or they saw it as just a gust of wind so when rainbow-dash told them about it they did not believe her because they did not see it

he changed the profile pic sorry but i dont like change

I think when rainbowDash first created the sonic rainboom that's when they started talking that it was a legend because it was long back

The phrophecy one was the best.

My theory is kind of mlp. You know raven from teen titans/teen titans go? I think her and twilight are the same being. Why? Beacause many reasons. Both of them are purple use magic and even share the sAme voice actor

maybe star swirl the bearded had his wings hidden under his cloak

i think it was her dad first

she isnt first, pinkie said "here" in that episode, which can mean ponyville.

my theory:

some of the ponies did the sonic rainboom from starting a loooong time ago, but in the time dash lives, no one did that, thats why it became a legend. at least they were so rare, i still dont think dash is the only one even if her time.
but its a legend so it must be done even before pillars in my opinion, i think a lot of ppl done that.

i think, different colored ponies can pull it with rainbow too, because they wouldnt call it rainboom if everybody pulls it in a different color. it should be: ponies in past did it always with rainbow colors even with different manes, thats why this legend called rainboom.

i highly believe that if fluttershy pulls sonic boom, she would make a rainbow too.

my theory: a very fast flying pegasus' magic can break light like water drops, thats why that magic wave changes the color of sky for a lil time. also ofc she doesnt reach the speed of light buuut no one said her magic doesnt. i think magic of boom can reach the speed of light, thats why all mane six saw it at the same time dash pulled it even if they are in different locations.

also even if she designed her fate with that action, this doesnt means she is the only one who can do that. all of us made huge differences in life that brought us here today. so i think other ones who did this had different stories with this boom and also flying talent ofc.

these are my opinions

I don't care what he changed but I want him to do more he is very smart

Imagine this in mlp when someone causes a sonic rain boom it goes to five ponies and erupts at the same time for all six ponies causes the six ponies get their cutie mark

When rainbow dash was doing the tryouts for the wonder bolts she got paired up with another pony she proved to be better than rainbow do you think she can pull of a rainboom

It was probably just a forgotten art. I mean, how hard is it for ponies to figure out what happens when they just fly really fast? One of them would have figured it out eventually. Rainbow Dash was probably one of thousands to do so.

You know what I think? Maybe someone wrote a fictional book on the sonic rainboom… (?)

My favourite one what is the scientific one because it was short and realistic.

Wait-
After doing the math, you’ve graduated college, am I correct? And if you don’t mind me asking, what did you get your degree in?

The idea of Rainbow Dash not causing the first Rainboom, is quite a solid theory. But Rainbow Dash could be the first to cause a rainbow colored Rainboom. While the first was not rainbow colored.

Wait, I just realised, If Rainbow Dash brought the mane 6 together, then why does dash ( Rainbow Dash ) get such a rubbish element ( loyalty )? At the very least she should get a better element ( maybe kindness because that is the main thing in friendship). Why can't she get to be an Alicorn? She doesn't have to be a princess, yet still is treated with plenty of respect, so I think that is reasonable enough. I know that some of you think loyalty is quite a good element to have, but I don't. And also some of you might think that you have to be a princess to be an Alicorn, but no - one has proven that yet so yeah...... Oh and another thing, what exactly did Twilight do to get all the glory? It seems Un-fair on Rainbow Dash. Let me know what you think about Twilight taking the glory from Rainbow Dash, when it all started with rainbow dash.

i think the first person or pony that was the first to do one was clover the clever as a alicorn

I know dashies papa had a rainbow mane so I think that he could perform 'secret sonic rainbooms. I put secret in inverted commas because I am not entirely sure if he could or not. I hope that you make more videos brony, good luck at the thing that I can't remember that you literally just mentioned, it was something about school, well I think so! byeeeeee! !!!

Ther is something to do a video about: the mane 6 is powerful then celestia?
After all, the mane 6 was the ponies that bring luna back, not celestia...

You'll see how importent the rainbow was in the season 5 finnally.

Unironically first.

Problem?

i think that those were different things though because Rainbow dash got her cutie mark after the Rain Boom and the one for Twilight was just a giant star in the sky

Perhaps, it was somepony who was long before to last RD and did the Sonic Rainboom, and then it was known possibility, but then, from generation to generation, it became unknown again if it was true, and was then a legend, and RD renewed it! LOVE YA RD! (she's not my fave, all the mane six are)

This is a different subject, but in Crusaders of the lost mark, towards the end you see twilight bringing in playground equipment. but when she flew she had wings like rainbow dash. she had wings more like cadence's. ERROR. ERROR. ERROR.

Is the sonic rainboom the same as what clover the clever did when he/she started the warm fire from his/her horn.

I herd on the wiki before that Soarin and Fleetfoot can pull off a sonic rainboom

I think there is more than one kind of rain boom because when twilight becomes alicorn she makes some what of a rainboom

The Brony Notion how do you feel about the new generation of ponies...Starburst, Prism Bolt, Clarity, Turquoise, Anthea, Golden Delicious, Cotton Candy, and Nidra

awww im starting to think how old he is and what he looks like

I think a legendary pegisi might have just pulled off a sonic rainboom.

I just realized that you and I are around the same age, that is if you were 17 when you made this video. It is crazy that this video was uploaded five years ago now.

Well, lemme begin with this: How do we get our legends?

2:30 And the Season 5 finale proves that!

Hi, the last possibility you told is wrong. You told that the sonic rainboom was a phrophscy and got passed down to genarations as a old mairs tale and since even the return of nightmare moon was a phrophscy and got passed down to genarations as a old mairs tale, you are telling you are right. But the old mairs tale that got passed down about nightmare moon was just about nightmare moon getting defeated by princess celeastya, so you are wrong .

i think back when the 3 tribes were driven togeather it was befor even then! the leader of the pegass pulled the stunt and then she became the leader but is still leaves the question were there leaders of pegasses befor her?

I like your last theory about the predicted rainboom. This is becauz its most likely. Also if your theory is true, then I think Starswirl the Bearded would have done it. Okey byeee

I think princess celestia was the first one and got a horn

a legend always begins with a truth and that shall be past on to some day be proven

I think when Celestia banned her sister to the moon you can see the sonic rainbow may be thay could be the first 1. Maybe😉

I think she’s not the first pony to make a sonic rain boom but I think she’s the only want to make it Rainbow 🌈

“It’s probably that they came from the same source”
Me: WIKIPEDIA

I think it could have bind her dad because he has rainbow hair too

Was it flash Magnus who was the first? He and rainbow dash are very similar

I like the third best.

I don't think it was the first rainbow because otherwise the mane 6 wouldn't have the same cutie mark

.. I liked the 3rd explanation better cuz it makes more sense!

The sonic rainboom was performed by RD's dad (theory).

I really like how you talk about the mlp eps

I think that it was never actually performed, but rather it was a fictional story and rainbow dash actually was the first pony to do it.

well i dont think rainbow dash is the firat pony to do the sonic rainboom because in season 5 in one episode spitfire says that rainbow dash could even beat a record of a colt.

i kinda liked the 3rd one

I think some ponies tried to make the rainboom🌈 before but failed

Maybe the Pegasus who did the rainbow was sornambale one of the pillars and a friend of star swirl

I think you are correct because it had to be some before or they would not know about the sonic rainboom

I've a question, When Rainbow was little, She done the first Sonic Rainboom. And reamber that part when Rarity got wings and they burned in the Sun. Didn't Rainbow do a Sonic Rainboom. Saving her, and everypony acted like THAT was the first Rainboom. SOMEONE HELP ME I'M CONFUESED!!!!!

What about when tirek was taking over the princesses gave twilight there alicor magic which made her super super fast even faster than rainbow dash. Mabey something similar happened in the mares tale

Well twilight put wings on rarity and if starswarl was the beast wiserd maybe he put wings on himself and did the rainboom

Yeah!!..Celestia also made a rainboom when she banished Luna on the moon..

i think she was first but i think a few fillies might of made up a story and it spread and went down in history

Number 2 is my favorite who agrees with me?

isn't it obvious that rainbow dash made the first sonic rainboom

Rainbow was not the first, I think it was her dad.

Or maybe is something like mix of 1st and 3rd explanation? I mean something like... firstly there was some pagasus legend, which interested some ponywizard - maybe starswirl - who do many research on this topic and prove that this really could happen, but through the ages no one can do it... or vice-versa - prophecy come from some scientific research, in which was discovered, that something like this could happen, but no one succeded in doing this... and years later this was remember as a prophecy, that someday somepony will do it.

Rainbow's father was first one to pull of a rainboom Its not a mare's tale it's a colt's tale😅

rainbow dashs great great great great great great great grandfather? far in the dashs family history? if so then that is why rainbow dash is able to create the sonic rainboom!

Season 5 proved Equestria wouldn’t survive without the rainboom

Maybe flash Magnus or another Pegasus pillar an Allie of Star swirl?

I think Rainbow Dash was the FIRST one to do the sonic RAINboom, butttttt there could have been a different Pegasus a long time ago who just made a sonic boom.

i like the first one best

well i dont think rainbow dash is the firat pony to do the sonic rainboom because in season 5 in one episode spitfire says that rainbow dash could even beat a record of a colt

well i dont think rainbow dash is the firat pony to do the sonic rainboom because in season 5 in one episode spitfire says that rainbow dash could even beat a record of a colt

No, because in the new book wonder bolts academy it's says that the wonder bolts had done it too and they came before dashie

Yes!!!! I love my little pony and rainbow!!! 😎🤗

Or Star Swirl went back in time...

exactly!!!!If it was the first Sonic Rainboom how come there's legends of it?

I actually think about the first the first Tony might actually be maybe Rainbow Dash's parents cuz I could have Rainbow Dash could do the Sonic Rainbow maybe with their hit her parents who did it I don't know for sure but that could be the explanation for this

i think someone realated to rainbow dash was a scientist and knew about a sonic boom and some how was a unicorn so he/she predicded someone would pull it off in the family and created a ledgend about it and since the family has rainbow coloured mains he/she created something called a sonic rainboom.The name sonic rainboom was probably created because the word rainboom sounds like rainbow and was realated to a sonic boom so rainbow dash must have been the first pony to do a sonic rainboom.

I like the scientific theory and I have only been watching for a bit but I think you really good at what you do.😛😜😝🐯🐆

The first rainboom was performed while banishing nightmaremoon.

And Lighting Dust was in von episode did it too.
But was not rainbow colors,but was orange and he'll blau.

Its probably Celestia when she banished Luna to the moon. There was a rainboom happened

no, the first sonic rainboom is actually When Luna was banished to the moon ... I'm just telling this for your information

Yes because only rainbow dash can perform the sonic rainboom

Maybe Rainbow Dash's dad did the very first one to do a rainboom??

I have no opinion. Instead, ask starlight glimmer for that, so she can travel back to time and see the first rainboom.

Do more please I've subscribed

I like the first one

With out the main 6 Equestria would be on fire, Pirncess Celestia would be dead, Nightmare Moon would bring internal night.

I know of a giant boom it’s quite deadly

Your wrong first ranbom is from 1.celestia when she's gonna seiled nitmare moon 2.rainbow dash when she's trying to protect flutter shy

maybe star swerl was testing if eany magic happend while fling realy fast and he came to an conclusion that a sonik rainboom was real but he couldn't prove it because know one was fast enof to prove it

What if the pony that pulled off the first sonic rainboom was Rainbow Dash's Dad?!

maybe the wonderbolts where the first ones to make a sonic rainboom

Ever noticed he misspelled propechy and he spelled tales as tails like a cat tail not like a story/tale?

I like the 3rd one, who's with me!! ;)

I like the fulfilled prophecy theory best. And that RD is the first (since that's what I thought since I was 7)

Rainbow Dash+Rainboom+First Pony+makes the Story=Alicorn
Twilight Sparkle+Magic+Alicorn\Unicorn=Normal Pony

Black hole theory fits here!?

My theories are either it was a prophecy or has been done before but with someone else with a rainbow mane... Probably rainbow's ancestors??

What if some pony went back in time

Hey, when luna was banished there’s a rainboom too

Rainbow Dash is not first to make Sonic Rainbow. If you look closly when Celestia send Nightmare Moon to the moon, and when she hit the moon Sonic Rainbow apired. So I think Princes Celestia was first to "do" Sonic Rainbow.

his dad was married to flutter fly he kept on racing with his rainboom and then now nobody believes in it

I ,think rainbow did do the first sonic rainboom cuz when she told her cutie mark story she said "I made the impossible happen"

Could it be, The Rainboom is not scientifically possible, so when Rainbowdash did her 'first' Rainboom, it was said be to a mares tail or some miracle. :/?

WHAT ABOUT LUNAS BANISHMENT THERE WAS A RAIN BOOM BECAUSE THE SPEED SHE GOT WHEN CELESTIA ZAPED HER TO THE MOON!!!

That was not the first rain boom his first own when he was a kid that’s how he got his cutie mark

anyways he wrote about a sonic rainboom and how to do it (I think) and then maybe dashie did it in the race when she was a little filly without knowing

maybe,she is the reincarnation of that pony who did it a looooooooooong time ago🤔,just my theory cause I believe in reincarnation 😶

Time Travelling Rainbow Dash? In order to get back home Rainbow must preform a triple rainboom (faster than sound, then light, then magic) where she becomes a bolt of lightning and must strike Twilight's depowered horn.

Rainbow Dash then becomes the first Alicorn Princess of Speed! She leads the Wonderbolts and learns to generate Fire-Works to make their shows even more awesome.

Wait... The stars will aid in her escape? Soooo Starswirl the Bearded?

It is a possibility that it's not the 1st sonic rainboom

I think Flash sentuary was the one to make a rainboom

Maybe it was Rainbow Dash's mom, but she died shortly after it happened and Rainbow Dash knew it was her mom but kept it a secret.

I think that just like rainbow dash's rainboom made the main six to come together, maby some pony in ansieant time did the first rainboom and he/she made all ansieant main six to come together and then she become the first one to do rainboom . and I guess that sonembula and flash magnus could be the first one to do the first rainboom.its my theory😏😏😉😁

No, because they all knew what the sonic rain boom was before she did it.

What if, only people from rainbow dash’s dad’s side of the family(the rainbow hair origin) can do a rainboom and one of them did it

i get it it might have been one of rainbowdash's long lost grandma

WHO GOT THE "LORE" REFERENCE?!

Of course I did. My dad's a geek.

Well... same source... Luna going to the moon by Elements of Harmony was the first.

I think Rainbow Dash was the 3rd pony who did the sonic rainboom so...

Or maybe starswirl is a Alicorn after all we always she him with that cloak...

Maybe the rainbom was actually different than the 1 than rainbow dash did

Who else thinks Rainbow dash should be the main pony? She was the one that made all of the main six get there cutie marks by the sonic rain boom so yeah I'm thinking that rainbow should be the main pony :)

I think that the first one who did the Rainboom was RD's great great great great great great great.....great great great grandfather/grandmother.

So flash magnus got his friends there marks now this could be a possibility

Ok sooo here is my theory rainbow dash was the first pony to ever creat the sonic rain boom but you know when rainbow dash said she had proven the legends to be true? Well I think a pegusis before her had attempted to make a sonic rain boom but failed so other ponys started making legens and rainbow dash actually was the first ful to do a sonic rain boom do you like my theory?

its "legend has it that on the longest of the longest day of the thousandth year, the stars will aid in her escape and she will BRING ABOUT NIGHT TIME ETERNAL" (or at least what I heard)

pls don't stop making videos!!!

I like the most interesting one. 🏳️‍🌈🌈

Rainbow dash is the most important pony of all she did the rain boom which gave everyone there cutie marks

Things may come and things may go .....sounds familiar?

I am not going to agree that rainbow did the first one but I do wanna know who did it

It's not just a mares tale RainbowDash's dad wich his name is Spectrum streak he is the exact same color as RD but he has yellow eyes one day when he was practicing because he was a wonderbolt he did the sonic rainboom wich that's how RD got to do her sonic rainboom she got it from her dad since she looks so much alike him.

My theory is darig did rainboom before
Cause maybe she did the rainboom and loosed the color of the her mane

I think rainboe dash was the first cause it was said its a legend and rainbow dash is the only one the can pull of a sonic rainbow in the wonder bolt

Maybe Flash Magnus did the first rainboom

i think celestia has something to do with this... celestia chose rainbow dash to collect other ponies for the elements of harmony with out her knowing.. and why are they all girls?

what if rainbowdash traveled back in time and created a sonic rainboom there

i think she might be the first because its called a sonicRAINBOOM

I think that's a good theory

I think Rainbow is still da 1st pony 2 pull off a sonic rainboom

Maybe the series were before rainbow – did her first Sonic rainboom and when she did she called it that cuz she heard legend of the Sonic rainboom

I think that the first to do the first rainboom must have been related to Rainbow Dash because it wouldn't have been a rainboom if it wasn't in rainbow colors!!!!!!! so maybe a relative of rainbow dash from the time before the rein of Celestia and Luna!!!!!

What if rainbow dash was the first, but another pony did a different colered boom.

I think the first reason makes the most sense.

I LOVE RAINBOWDASH
SO I SAY YES SHE IS THE FIRST ONE WHO
DID A SONICRAINBOO

remedies is not actually the first pony but actually the first filly who did a sonic rainboom

rainbow dash wasn't the first, but it could have been one of rainbows ancestors, as pinkie pie said " when a Pegasus pony like rainbow dash gets going so fast a rainbow and sonic boom can happen all at once". so only the most dedicated athlete can achieve one, like we can run but we can't all run at 30 m/h.

After A burst of MAGIC
A blast of MAGIC happens it makes a blast of
colors. I mean to the color of the pony using the MAGIC
Rainbow makes a Rainboom and Twilight can make a
Twilightboom? Because Twilight made her 'boom" with MAGIC
aND peguas fly super fast and they make their "boom"
Earth ponies run super fast and make their "boom"?

I think one of rainbows dash’s old ancestors did a sonic rainboom

I think rainbow dash was the first one to do the sonic rainboom

I think rainbow should be the main carecter

A Doctor Who video maybe 😊?

Maybe the Pegasus ponies saw a rainbow, but the only way to explain it was the sonic rainboom. Maybe?

I don't that was the first rainboom

The rainboom been a legend if it never happened

I have a theory on this what if Rainbow didn't do the first sonic rainboom but also did do the first sonic rainboom think about it for a minute

The only ponies that we know now that could perform a sonic rainboom would be rainbow dash and celestia coz of their rainbow manes, no?

i think they should make a vid about the sonicrainboom

When the mane six vanished night mare moon it makes a rainbow. I think the rainbow was the sonic rainboom.

Hi im a new pony the theories are correct but it may be a princess before celestia and luna mum and dad

Maybe Flash, one of the pillars.

Rainbow was not the first one to make a rainboom because how would she know that a rainboom exists the story was probably past on from generations from Rainbow Dashes family I think that she just got lucky that she did the Rainboom because she raced the bullies from her flight school for flutter shy then she just went WAYYYYY to fast so she didn't even know that she could make a rainboom so I think she is a special pony or she just really got lucky 🍀 By the way I'm a rainbow fox 🦊:D

What if one of rainbow dashes ancestors or relatives pulled off a sonic rainboom because their mane has had to be a rainbow pattern like her parents.

Maybe it was Rd's mum who did the 1st and rainboom.

Maybe he made it!

or maybe when the 2 sister use the elements of harmony becase when the mane 6 is using the elements of harmony on the lost harmony part 2 or something like that when they use it there is also a sonir rainboom
P.S make that a video theory pls ☺☺☺☺

what if rainbows parents did the first rainboom? 😦😱

--> Maybe someone in Rainbow's history / one of her ancestors did the Sonic Rainboom at first so its in her DNA? idk lmao

this means the 2 isn't as likely because fore it to be known as the sonic RAINboom a RAINBOW colored pony wold have to perform it if your magic theory is correct

the hole point of a sonic-rainboom being called sonic-rainboom is bc of its colour

No because remember the one when Rainbow Dash went to the training camp she had a rainbow trail remember and there's another girl which is as fast as her she had a lightning Trail maybe they did a rain boom or light boom at the same time but further away from each other

its obvious it was one of rainbow dashes relatives who made the first one

The mane 7 spike is left out .

Dude make a explanation on how changelings change theyre form

How About the mane six traveled through time and Rainbow Dash create the first rainboom, this somehow also make sense of my theory that they become the element gems itself to reborn in the future

I think yes for rainbow and number 3

The best explanation is number 3.

2. Rainbow Dash Is The Most Fastest Pony In Equestria. Maybe There Was A Pony Who Did The Rain Boom Or Discovered The Rain Boom Beafore Rainbow Dash but they wrote it as a old tail so everyone started thinking that it was and old tail. 2. The elements are conected to all sixth and they all have diffrent element colours and rainbow dash is conected to one of the elements and also rainbow dash's element is red, the lead colour of the rainbow so maybe that's the awnswer

maybe it was windrider the greatest wonderbolt who ever live he's first appearesn is in rarity ivestigates but the he got abbended

Rainbow is the first child pony to do the rainboom that is my theory

Oh no, he just made My Little Pony scientific.

well I watch a video of rainbow dash family and rainbow really look like his father because rianbow's father has rainbow tail too.I bet rainbow's father is the 1st one to make the sonic rainboom.

well I only know that the pony who can pull another sonic rainbooom is rainbow dash's parents or the pony who has the rainbow colored mane but the only one who has a rainbow colored mane is rainbow dash's family maybe they were the one who did the sonic rainboom before her

We saw when nightmare moon was banished a rainboom came from the moon

Video request how come moon dancer isn't in Crystal Prep

Wait maybe rainbow dash time travelled just like you said with twilight but just as another person it was reborn making it that she doesn’t really remember it also another thing what if she time travelled when she grew up while it was twilights reign when like you know after season 9 but she did it without realising or like realising after she had dont the sonic rainboom.

she was the one to pull off a sonic rain boom and maybe twilight help name the sonic rain boom

i like the 3 one

Rainbow Dash was the first one to do a sonic rainboom

maybe camander huricane or flash magnus performed the first rainboom

Maybe it was one of her predecessors at was the first (but just maybe)

Well my thinking is no it was not the first rainboom because in your video where you told us why you thought Rainbow and Daring look alike well maybe what you said in that was true but I think that daring did it first and then rainbow maybe rainbow might pass it down or another pony will do it!

I just realized... celestia and Luna are older than dumbledore

I’m rewatching this at the end of my senior year of highschool
I had to google what senior year of highschool was because we don’t call it that in Canada, as far as I know at least 😂

Fluttershy did it. Rainbow did the Sonic Rainboom, but Fluttershy caused it. You see, remember how when Fluttershy said that when she went to flight school as a filly, she was a weak flier? So if she hadn't existed, the two pegasi bullies wouldn't made fun of Fluttershy, Rainbow Dash couldn't stuck up for her, Rainbow Dash and the two wouldn't compete in the Pegasus Race, and Rainbow wouldn't complete the Sonic Rainboom.

Maybe it was pridicted and then sort of got forgotten

Twighlights did her own type of sonic rainboom a few days after becoming a princess

I think there was one more because how the heck would they KNOW about the sonic rainboom

I think the first one could be rainbow dash's dad or mom

I don't think it was the first cause I remember in the time episode when they were in past baby rainbow dash said that's just an old mare tale

So flash Maignus may have caused the first Sonic rainboom and did the same thing like rainbow dash and give him and 5 are there cutie marks and people thought it was untrue until rainbow dash people did the same thing makeing that true

Except for Dash's father, who hs a rainbow coloured mane?

when celestia banished nightmare moon to the moon you see a rainboom

Maybe it was celestia? 😕

How did the sonic rain boom work

If Rainbow dash made the rainboom and united the mane six, wouldn't she be the leader?

I have a question.What happens when starfire bece an alicorn did the others get imortalaty or are they going to die?

Probably she's the first one to do this BUT in ponyville

Twilight did it when the princess gave her there magic there were stars behind her in stuff

The sonic rainboom costed the main six to get their cutey mark so the main six might be related some how some of u guys might think that that’s not possible because the cmc aren’t related but they got their own together at the school house twilight is conceited with her friends with the six stars on her flank rainbow dash got her friends their cutey mark so why haven’t the main six men

Hmmm mabey the story was just a fiction book? so rainbow was the frist pony to pull off the rainboom?

pretty much rainbow is the most imprtant pony and dats y i like her the most

I don't think Rainbow dash is the first pony who made a sonic rainboom

So what if someone made the Sonic rainboom but they didn’t pull it off so then Rainbow Dash did it

I think that the first pony made the rainboom was rainbow dash's dad

I think that the first pony made the rainboom was rainbow dash's dad

Maybe she had to fulfill her parents hooves steeps?

Didn't you her first rainboom - made cutie mark . Huh Galaxy Lover Girl.(now I am guilty😣)

How did it get the name "Sonic Rainboom"

The fact that ponies have even found out about what a sonic rain boom even is? Of course this isn’t the first rain boom sighted or created

Maybe flash mangos made the first rainbom

Hey I think flash magnus did it

Maybe Rainbow Dash Dad is the first doing the sonic rainbow because Her dad is fast and he love flying
I think rainbow Dad is the one who the first doing the sonic rainboom

Yes yes she was the first one

We all know that Equestria wouldn't survive without the mane six because of the episodes the cutie re-mark part 1 and 2

I can't be prophesy because u said the rainbow part was a reflection of the pony. They wouldn't know that it would be rainbow dash to do the rainbow. If I twilight did a sonic Boom would it be sparkly?

Actully Rainbow was the first pony but when princess Celestia become a alicorn she discover sonic rainbow

number one is my favorite

she was the first child to pulled of the sonic rainboom

I like the prophecy theory

really, if there were stories about the rainboom, then some pony did it before rainbowdash! like you said, just like nightmare moon, there were stories but she was real, so...I guess rainbowdash is the 2nd..... And, I'm a kid on my mom's phone XD So... some pony did it first, but we don't know who... (I love you brony nation!!)

Maybe her dad made the first sonic rainboom

No, they were a Rainboom when celestia banished luna into the moon and the rainboom appeard

I don't think this is the first rainboom if it was no one would know about it

Cause I’m a warrior cats fan I say it was a fulfilled prophecy

Wait then he is a HUMAN?!

Also starlight seeing this video
Starlight glimmer: hmm interesting

Maybe someone related to rainbow dash like her great grandmother so it would be possible

The first pony was rainbow dash's father
Because he and she has the efect on their tail

Ooh ooh I have an awesome guess of who did the first sonic rainboom: It's ether commander hurricane or rainbow dash's dad

What if it was RainbowDashs mom who did the first Rainboom

Congratulations my brother just graduated from high school I hope you do well in high scho

I think rainbow dashes dad was the first one to do a Sonic rainbowboom

I believe it is a fulfilled prophecy

I think somepony once told a rumor and rainbow dashe proved that the rumor was not a rumor and is a true story.

She is the first one who can make it be true 🎯

Rainbow Dash is not the first pony to pull off a sonic rainboom is my best theory.

Both "tails".nice one✌

The first sanic rainboom is 40 trillion years ago (fake fact)

I think the first rainboom was Rainbow Dash's father

I donypt think rainbow dash was the first to pull off the sonic rainboom maybe a pony was the first one to pull off a sonic rainboom in the olden days before celestia and luna came

maybe dash's ancestors did one

without rainbow dash, equstria would be doomed. she is the main reason why equstria is still alive.

I think rainbow dash was the first Pegasus to pull off a sonic rainboom and I think that somepony made up the story and rainbow dash thought that it was true many ponies said it was a pony's tale but Maybe the sonic rainboom was made up and rainbow dash was the first to ever do the sonic rainboom

rainbow dash did her first sonic rainboom when she was in her first race to defend fluttershy's oner

Mabry Celestia was the first to pull it of?Um,I dunno,I'm just random.

it would be celestias mom or something

The pony who pulled it off was in one of the seasons episodes.....I don't remember which one it was but it had to do when Rainbow Dash met a famous pony who he said he believed that Rainbow dash could beat his record

her father was the 1st one who did it!!!

Rainbow Dash is the first pony who proof the socnic rainnoom is ril.

The elements create the first sonic rainboom

Maybe her dad of Rainbowdash did it first 🌈

My theory is no, because how would anybody know about the rainboom unless it’s happened before.

RAINBOWDASHS FATHER MADE THE FIRST ONE WHEN HE WAS STILL LIKE A BABY OMG OMG OMG THATS GOTTA BE IT

rainbow dash was a fist one but her dad done a rainbow boom but everyone think it was

I think this was the first sonic rainboom because it makes a rainbow like rainbow dashes name

Good job

rainbow dash is the first pony who did a rainboom

I love mlp

first of all, commander hurricane is a dude bc in the first hearth warmings episode with the play in season 2 , spike literally said HE and fluTTERshy kept saying sir

Have you ever wondered what where Princess Celestia and Princess Luna's cutie marks came from how do you earn for a wonder about that

Just me think it is a TIME TRAVEL ?







Or Pinkie Sense can Explain ?

Wait are you connected with Star Trek? I love you! Ahem sorry. I'm glad you like it.

Dude your lucky. My school starts at the beginning of August.

No. If that was the first sonic boom celestia and Luna were like 😱 what the !?..

Remember cause without rainbow dash rainboom see all the equestria it's worst and in the season 5 last episode twilight say that......where we came from there is no war with king zombra......so if rainbow dash do the rainboom there is no war with king zombra which the 1ST WAR...

In princess twilight sparkle when celestia banished luna a rainbow came that might be the first sonic rainboom

Interesting. I suppose so.

Yes she is.

Celestia exists. So probably prophecy

Without Rainbowdash equestria would be doomed

maybe her dad made a 🌈boom😞

well rainbow's first sonic rainboom is her filly days

I think the rainbow was made by a peaguses and starswirll

I like the prophesy theory

Rainbow Dash not the first. It makes more sense. They say legends are somehow based on truth.

celestia caused a rainboom when Luna was bamished

rain bow dash wasn't the first it was cadence cause cadence was born a Pegasus

What if rainbow's ancestor did it

make more videos i am a big fan

I think that Dashs DAD did it... If you watch InkRose you will find it

I THINK THAT THE FUYURE RAINBOWDASH MADE THE FIRST RAINBOOM

SHE DID A RAINBOOM AND GOT HER CUTIE MARK WATCH THE SHOW!!!!!!

think about this rainboom Rainbowdash they both have to do with rainbows in that one episode Twilight did a rainboom except it was her cutie mark or a purple star and Twilight is purple my theory is that only rainbow ponies can do rainbooms and other ponies like Twilight did can do rainbooms too except they show up different. colors so rainbow dash probably was the first to pull it off but that's only because she was rainbow

Remember when rarity had butterfly wings the to ponies that were mean to rainbow dash saw her pull off her sonic rainboom but in season 2 or 3 they told her her it was just a old mares tale so aren't they lying???????????????????

If Rainbow Dash was the first to create a Rainboom why isn't she an Alicorn? I that proofs enough magic to be one.

It's sad when you started your senior year of High School.😢. But you probably need to do daily uploading it you have time. ☺☺

No it was rainbow entering the puberty x'D now she eats way more vegetables

I think that was the first rainboom bit there's something called a alicorn boom "from twilight on the second summer sun celebration. If

maybe it wasn't even a Pegasus it might if been a unicorn or alacorn because twilight did do something like a sonic rainboom but with her colors and with magic and alacorns have wings and a horn

Then what was the (ponys) cutie mark??? If the (pony) did the rainbowboom what was the (ponys) cutie mark??!??

Yeah.... how do they know about sonic rainboom? I don't think rainbow was first i mean she is rainbow colors but how do they know? Maybe.... if some one long ago see in the future......?

it was proven real by rainbow dash when she was a kid

I feel like rainbow Dash's dad because her dad has a rainbow mowhock

NO......HER GREATGREATGREATGREATGREATGREATGREATGREATGREAT GRAND FATHER DID IT. BLAME HIM.

Maybe rainbow dash should be the princess because she made a sonic rain boom 💥 made everyone else get there cutie mark so see what you think

what was starlight glimmer doing in the resturant in the episode when twighlight sees her old freind

Maybe Rainbow Dash's PARENTS did it!!!!😱

what if it was celestia

I think that Princess Celestia is first pony who make sonicrainbow. I think that beacuse when she send Nightmare Moon to the moon for 1000 yeaes, Nightmare Moon (Luna) hit moon and then sonicrainbow show up. That is my teory and sory for grammer mistakes I don't know english very well.

They have a ep on the non equestria without the rain boom thing

what about when the main six got there cutie marks, rainbow dash also made a sonic rainboom

well! idk why they need the 6 cause if there was no such thing bad happenignthat the villans would aim for and anyways!!!! in the part where starlight travels to a new time and she stoped the sonic rainboom wouldnt its be the rainbooms fault not the main 6!

Rainbow is the first one to do the rainbom

rainbow was the first because she has a rainbow main.

Maybe A pegasi you know they control the weather so ummm you know Rainbows are form if they are rain and a sunny weather going on maybe a pegasus or two has noticed what is even there is no rain a rainbow will form..then they like imagine some things like a pegasus will fly fast and boom! a rainbow will come..and mares like tell the other ponies if its impossible like that..and then nobody can do it..cause a rainboom can only be done if a pegasus has like a rainbow trail or whatever you call it..
So only rainbow dash can do it cause she is the only pony that has rainbow whatsoever...So maybe thats it

PS: Im 10 yrs. old

I guess that rainbow dash was not the first one to make the rainbow because
I guess that the rainboom could be done by hes father itself

I like the prophecy theroy

I thing that it is coincidence. Some one made up a thing and told everyone about it.

I think that Rainbow not was the first to do the sonic rainbom. Maybe hers dad or someone in hers famaliy did the sonic rainbom.

2:49 i saw what you did there

at least the first pony if there was

i think it is a fulfilled prophecy

The show,s are cool.

Hey this show wouldn't have happened if those bullies where nice ponys!

Non-pony related vids you say? Steven Universe maybe??

I Think That Rainbow Dash Did Do It Because The Rainboom Is Real But The One That Did It Tried But Didn't Do It But knew It Was Possible

could you please Post a video about how you make videos?

Maybe only ponies with a rainbow tail or mane can do Rainbooms. Could be relatives of Rainbow Dash.Like if you want this to be a video

It's Possible That Her Parents Pulled It Off Because She Was Born To Pull It Off Bcs The Rainbow Hair? And Super Flying

she is the first rainboom

MAYBE they just guessed about it.

Maybe it was her grandfather

If teric took rainbow dashes powers then can he do a sonic rainboom

ranbow was the first! as a kid

can there be difrent types of rainboom example if twilight learned fly that fast as rainbow dash maybe there will be sparkleboom???????

star swirl looks nothing like that

maybe twilight traveled througt time and told people.

it was her dad first.

Well i can maybe help so the rainboom.......Well...ya see..... You confuse me :/

Didn't Twilight do one one on the episode Princess Twilight Sparkle

This is Mandy the first rain boom because they couldn’t be anymore rainbow ponies..

I think the pony who pulled it of is a ancestor of rainbow dash

Rainbow Dash mother was the first Pegasus to do the first rainbow

No because if celestia luna sent to the moon then was a raimboom

Do Littlest Pet Shops

He just predicted Cutie Re-marked..

Maybe it was just a made up story by somepony who saw a pegasus flying super fast and almost got it but inly got so far as to make a few sparks but then the story got based off of it all but was over exaggerated and got super popular it science nopony was seen doing it it was just seen as an old mates tail until Rainbowdash accomplished it

YOU SHOULD MAKE THE POFISY😍

The Fulfilled Prophecy and yes rd was the first

I think the mayor had dreamed it and told everybody and and somhow connected it to rainbowdashes biology

Foresight sawtooth waves 😉

If your asking Brony Notion to change his OC or Avatar, it's for the better

She is the first cuz she's awesome

Mayjen rainbow wentback in time to do it
