What is batman's superpower?

Answer 1

he does not have one he uses gadgets.
Batmans superpower is being Batman.

Seriously though, Batman has no superpowers, it's the primary factor of his character, he's a human who trained to be the best he could be to save the city that he grew up in.

If he were to have any superpower though, it would probably be having muscles that don't wear down as quickly as most humans.
