Adult Cartoon lore vs Kid Cartoon lore

Description YT

Lemme tell you about My Little Pony lore:
So basically, there were 2 sisters, Celestia and Luna who ruled the land of Equestria, they held the Elements of harmony, and used them against tyrants such as Discord(Not the app, but the app is quite a tyrant too) eventually Luna was banished to the moon for throwing a tantrum, and thousands of years later, 6 mares were brought together after Luna escaped, she was good again and the mares held the elements now, Discord came back, was defeated again, a bunch of changelings crashed Twilight's(The main character btw) brother's wedding, but were defeated, then a dude named Sombra attacked the empire ruled by Twilight's big bro, but were defeated, a centaur named Tirek came, but was defeated of course, then Starlight Glimmer came, was reformed, and then eventually the elements broke, and turned into a tree, and then eventually a school opened up, and then an evil child named Cozy Glow attacked the school, but was banished to Tartarus which is basically pony hell, then Tirek, Cozy and the queen of changelings attacked, but were turned to stone, and then Twilight is queen
and that's just the beginning, I haven't even mentioned the other Mane 6, the student 6, the Cutie Mark Crusaders, or the fact that it, Rick and Morty, and Doctor Who exist in the same multiverse, or Derpy(who is supreme waifu btw)
And that's not even counting the comics, the movies, the other generations, the fanfiction.
Proven my point yet? And My Little Pony isn't the only one, Thomas is even more lore filled, and Transformers, and Gravity Falls, even SpongeBob if you look deep enough.
My point is, step up your game, adult cartoons. I need a cartoon as packed as MLP with lore and story, but targeted towards an Adult Audience. The closest things are Invincible and Rick and Morty.
