There are some many i love, but if I have to choose one, it would have to be Spider-man. I know, iknow. He's the obvious choice, hes famous, etc. I like him beacuse he's an everyman. He had a hard time fitting in, he has HORRIBLE luck, fo all the good he tries he never gets anywhere. But still he fights on.
does it have to be DC? if so Then Green Lantern, cause he weilds the most powerfull weapon in the univerese.
