are we talking favorite hero based on publisher? Cause then they'd be Wolverine for Marvel, Batman for DC, Spawn for Image comics and it's a toss up for Buffy or Angel for Darkhorse.
Originally it was your favorite superhero. Then,i decided to throw the Marvel vs.DC card in.
And,yes shibby,they are still considered a superhero even without super powers. Like a previous post stated,high IQ,money,Advances in technology, and, just being a bad-!@#$.(As in the punisher)
Question: Can they be called a superhero when they don't have a super power? (just guns, gadgets, skills etc)
Batman has a genius level IQ, Olympian level athletic ability and money to further enhance it. Compare that, to say, Aquaman (not to beat a dead horse that is Aquaman bashing) I'd say he's a superhero.
Also, I find the lack of Tony Stark in this thread disturbing. Although I'll never abandon my lifelong favorite of batman (so it's a tie for me)
