Spiderman would be my close second. Even with special abilities he struggles like the rest of us with life's problems. Very relatable. I heard a quote about Spiderman that I thought was pretty accurate. "He's the punching bag of the Marvel Universe." I believe that. He gets little respect from the other superheroes but he has done his fair share of saving NYC and the world. The Rodney Dangerfield of the superhero world (for those who get that reference).
