[DC] Why is Batman (almost) always portrayed as a/the hero in elseworld stories?

Likewise, Superman is usually turned/is evil. Personally, I find it far more likely that Batman turns evil. Or, at the very least, another powerful hero like Martian Manhunter/Wonder Woman being evil.

Because that is Batman character. He is someone who walks that very thin line and refuses to budge and has sacrificed so much of his humanity to do so. It's his greatest strength as well as his biggest weakness. The others have more of their humanity and therefore are more susceptible to becoming their greatest fear.


I also don't know what you mean when you say Superman is usually turned evil. That only really happened in Injustice and the general consensus is that it's a pretty crappy portrayal of Superman despite it being a good story.
