1. Sentry
Nearly everyone wants superpowers, to be extraordinary, but can you imagine having them and giving them up? That's what Robert Reynolds AKA Sentry did, choosing to surrender his whole heroic existence in order to protect mankind from his dark side, The Void. And what a hero he had been! As a middle-aged writer and family man, overweight and depressed in other words, ordinary Reynolds becomes convinced that a grave threat is returning to the Marvel Universe. His investigations uncover a world mesmerized into forgetting the very hero he once was, Reed Richard's best friend, who The Hulk called The Golden Man. Sentry is characterized as a great hero, a great human being, someone who made the whole world better for his presence, but who gave it all up to protect the world from... himself. What greater sacrifice is there to make? He might not have the recognizability of some of the other names on this list but Sentry possesses a complexity and ambivalence that could make, not only for a great superhero movie, but great human drama (full stop).
