Aside from the Angella follow-up, I want any epilogue shit to be as ridiculous as possible.
She-Ra vs. Dracula. Nuff said.
It's Christmas Eve, and Adora and Catra are trying to get the last Turbo-She-Ra doll for Frosta (each thought that the other was buying it), but it's sold out everywhere, and also Lonnie, Rogelio, and Kyle are trying to get one for Imp, and they are NOT playing around.
Seahawk accidentally set a ghost ship on fire, and now ghost pirates are pissed at him. She-Ra must intervene.
Adora and co. travel to the original She-Ra's universe... literally use footage from the original show and have Adora and friends disguised as background nobodies, trying to solve the mystery of wtf is going on without altering the OG She-Ra's timeline (basically Trouble With Tribbles).
"It's a High School AU!" except it's not, it's actually everyone caught in a shared dream by a mentalist villain.
A He-Man/She-Ra Christmas Special
Bow's 12(?) brothers are in trouble, stuck in some spooky magic-dispelling tech-jamming ruins. Indiana Jones shenanigans await.
Everyone gets transported into a game of Labyrinths and Leprechauns.
And so on.
