CMV: Batman is not a superhero

A superhero is "a benevolent fictional character with superhuman powers, such as Superman." Batman does not have superhuman powers. Though I'm sure there are story lines where Batman borrows Green Lantern's ring or otherwise acquires super powers, I'm talking about Batman as he is normally depicted.

He may have abilities that are exaggerated and unlikely for a human being to possess--just as Sherlock Holmes, Walker Texas Ranger or any number of fictional people with high intelligence, martial arts and tech skills--but he does not have super powers. Even if he does things that are seemingly impossible for a human, that is the writers taking some artistic freedom on the limits of human abilities - he is still depicted as just a man.

edit: OK, some good responses here, and I'm going to hand out some Δs. One of the early responders hit it on the head in that I guess I'm just arguing semantics.

Use of impossible technology usually counts as well. Dr Doom is a supervillain, Iron Man is a superhero, Antman is a superhero.

Batman has stuff like his impossible grappling hook which is impossible for technology to produce. As such, he is a superhero.
