Obviously, comic book superheroes are fictional characters, so this list is really character names Chapter 3.
A superhero, theoretically, needs a secret identity to protect the folks he or she cares about from bad guys seeking revenge. If you were say, the wife of Batman and the Joker, who everyone generally concedes is bat-shit crazy, knew it, your life wouldn't be worth much. Now that is not to say that every superhero had a secret identity. In the Marvel Universe, Iron Man and Mister Fantastic (Reed Richards) both have come out of the closet, so to speak.
For this post I have concentrated on mostly the well known characters. The next graphic novel post will visit lesser know entities. And for the sake of brevity, I have limited myself to ten from DC and ten from Marvel, but be sure to look at the end.
