You get to choose a Fanon of your choice as the Fanon and Canon versions of that Fandom will meet

You will be playing the Canon be of the characters of the Fandom as AI plays the Fanon version of the characters of the Fandom

Or you can do ocs or fandom ocs instead, that's allowed

So grab your snacks, buckle your seatbelt, and hold on tight. This will be. A BUMPY RIDE!
