My choice would have to be Green Lantern. (check out my avatar!) Even though they have not made a movie for him yet. He is THE superhero. Afterall, I believe it was him, or they?, that guarded Superman as a baby while he was on his journey from Krypton to Earth. So you could say that if it were not for GL Superman may never have made it to Earth. Afterall, he does possess the most powerfull object in the universe.
