Spirit Animals: Everyone has pets but they pretend that they're more than pets. And then everyone dies.
Warrior Cats: An ancient animal shelter decides, "Hey, let's release all of our cats into the forest!"
Then those cats live there for like 500 years and stuff happens and everyone dies. (By the way, the animal shelter thing is just a joke theory. I know it's not part of the actual storyline of Warrior Cats. Don't kill me, please.)
The Last Dogs: A yellow labrador that is pretty much a stereotypical protagonist who has barely any personality traits besides worrying too much (basically Firestar), a dachshund whose personality is like if Shaggy (from Scooby Doo), Papyrus (from Undertale), and Peridot (from Steven Universe)'s personalities were combined, and a yorkshire terrier whose personality is basically Pinkie Pie's team up to find their owners because the government is mean and hates animals for some reason. I would explain why the government hates animals, but if I did, I would go on a complicated un-understandable rant for a few hours, so I'm not gonna do that.
Steven Universe: A bunch of lgbt rocks from space protect the Earth from other rocks from space. They also protect Steven, a half-human half-space rock that has been nicknamed "Precious Cinnamon Roll" by the Steven Universe fanbase.
Gravity Falls: Two twins' parents decide that it's a great idea to send their children to their great grand uncle, who is also a criminal for the summer. He just casually shoplifts things. And they just decide it's totally fine. What good parenting. Oh, and also, the place that they're sending them off to has extremely dangerous monsters and weird stuff everywhere. SUCH GOOD PARENTING.
Star Vs The Forces Of Evil: A magical girl with a magic wand goes to Earth and lives with a normal boy. What a nice, creative, exciting story that there are tons of possibilities with, and- Nevermind, we're just going to have the whole plot of season 2 revolve around teenage drama and drama in other dimensions. And season 1 is, like, at least 80% filler episodes.
Undertale: A game that's actually really good. Wow, what amazing characters and plot and- Oh, nevermind, it's already been ruined by the fanbase. What a surprise.
Pokemon: I'm only in the fandom because I have a huge obsession with the Team Rocket Trio WHAT I DIDN'T SAY ANYTHING HAHAHAHAHAHAHAHA
Yuri On Ice: Lgbt ice skaters.
Thomas Sanders: I'm not even sure if you could consider this a fandom, but since it already has two very popular ships, I guess you could consider it one. So, this YouTuber named Thomas Sanders makes four characters that are all supposed to repersent different aspects of his personality. There's Logic (who repersents Thomas's logical side), Dad (who repersents Thomas's morality and love of dad jokes), Prince (Thomas's fanciful side, who repersents Thomas's creativity and imagination), and Anxiety (who repersents Thomas's anxiety, duh.) And then everyone starts shipping Prince and Anxiety, and Thomas is aware of this ship, so he starts adding Prince x Anxiety moments to make all the Prince x Anxiety shippers go crazy. So the whole fanbase is basically just Prince x Anxiety shippers and a little bit of Logic x Dad shippers.
Stranger Things: A telekinetic 12-year-old lives with a bunch of other 12-year-olds, who are trying to find another 12-year-old who's in another dimension hiding from a monster. Yeah, there's a lot of 12-year-olds
