Mine is Spider-Man. He was always my favorite because he was fun to read but it was always the little moments that made me love him. Like when he webbed up a purse snatchers shoes so that someone wouldn't take them while he was tied up waiting for the cops. Or when he was getting his butt kicked by two of the Phoenix powered Xmen in the Xmen vs Avengers storyline and he kept fighting back and talking shit to them. All the little moments that he cares about people and never gives up no matter what. That is what makes me love him as both a hero and as a character.
