Since I'm never doing requests, here are some universe ideas I have planned so far, most of them Batman related. Let me know which one you want to see first:

The Batman Arkham Trilogy (Arkham Asylum, Arkham City, and Arkham Knight. All in that order. Maybe I'll show them Arkham Origins too at some point.)

The Dark Knight

The Batman

Young Justice (Let me know which season you want to see.)

The Flashpoint Paradox animated movie

The Batman: White Knight comic series

The Snyderverse (They would make fun of it.)

Titans (So they can make fun of that show too.)

Batman: Mask of the Phantasm

Batman Beyond (Both the first two episodes and the Return of the Joker movie.)

The Injustice games and maybe also the comics

Batman '89, Batman Returns, the Batman '89 comic series, and maybe also the Channel Awesome Batman Forever and Batman and Robin Fansciptions

And maybe a few other stories.
