Overall, probably Superman. Although his powers make him nearly invincible, the story of a lonely alien hidden amongst us on earth resonates, as demonstrated by multiple movies and television shows starring the Man of Steel. I am a fan of many comic heroes including Batman, Spider-Man, the Fantastic Four, the X-Men and many more. Personal favorites along the way have also been Warlock, Deadman, Metamorpho, and the Doom Patrol. But, our strange visitor from another planet with powers and abilities far beyond those of mortal men probably is number on3.
