There are just so many versions of these characters.

To be fair, I don't know how many actual new Batman comics there are out there right now. What I'm mostly remembering is a young me looking to get into comic books, and there being a ton of different versions of Spider-Man, X-Men, etc.

Me being a 90's kid, I basically just wanted X-Men The Animated Series as a comic book, which I'm pretty sure existed for a while even before they did some weird multiverse version of it later.

Even so, when I think of multiple versions of the same character, I think of Batman, because ye GODS are there a lot of Batmen. One could fairly argue Batman does anything depending on what continuity you're going with.
