Oh god, "Batman vs... THE GAMER-GATOR (what a gator-person was done before? stop mansplaining!)"
See, all the villains would get new "hip" repackagings.
Batman would become Batwoman (and any mentions of an already-existing character by this name will earn you a block on Twitter), but if you say that he had gender reassignment surgery, then you'll get blocked. She is a woman. She was ALWAYS
at war with Eastasia a woman.
Robin would retain his name, but would be retooled into Batwoman's husband, a short Asian man with stupid looking long hair. There would be evidence that Robin served as the sidekick to another hero before Batwoman, and abused them and burned them with a cigarette though nobody will be allowed to reference that and only the villains will ever bring it up, because they're evil.
The Joker would become "The Troll," and instead of deadly pranks and whatnot, his main power would be saying nasty things to Batwoman on Twitter (and there's NO EVIDENCE that Batwoman sent those messages to herself under a different account!!!)
Harley Quinn, instead of being abused by the Troll, would become the woman in charge who, is in charge of making sure he functions because after all he's a stupid male
Killer Croc would become, as you said, "The GamerGator," and his power would be to crash his car and then film a video screaming about it, causing Batwoman to cancel a planned convention appearance
Scarecrow would become "HateChan," and his power would be to send Batwoman death threats, causing him/her to claim to leave the Batcave out of fear, though a later storyline will present evidence that he/she was in the Batcave all along and simply made that up
Bane would become "TheBaneRetort," and his power would be to take pictures of Batwoman during a convention appearance, and he can only be defeated by Batwoman having security kick him out of the convention.
If I'm missing any, let me know.
