Batman: Endgame

Ok "“ so this one doesn't feature as many villains as it does superheroes. However, since this would be an adaptation, the Justice League attacking the Dark Knight could be replaced by some terrifying supervillains. Killer Croc, Clayface, Man Bat, Solomon Grundy, and even Bane could be used by the Joker to attack the Caped Crusader.

And this would be an interesting story to adapt, especially because we find out more about Joker and why he always manages to elude his nemesis. I can bet that this DCEU won't shy away from referencing the Lazarus Pit and the Dionesium"¦

Plus, this would also explain why the Joker is so crazy. However, do we really need that? Or is it better when this question has multiple choice answers? I'd rather prefer the latter. Though I am a little biased, since Heath Ledger's portrayal was all about that.
