Yes I know there are more than that but c'mon its obvious who are the more popular and most fan favorite over 50 of the Marvel & DC roster.
I never read the comicbooks until my teen years and then I got into manga more than American comicbooks but I think they were neat. I knew these characters in cartoons, Batman and Spider-Man were my favorites, Superman came close, he is all about truth and justice but Batman is more special, his origin is dark and sad and he's the most powerful superhero that is human. Spider-Man is an amazing character than can relate to alot of teens in their school life, not to mention both have awesome and memorable villains.
