Bruce Wayne/Batman

"'His parents died when he was so young. Shot. Killed right in front of him. He was raised alone. A kid in a huge mansion. With his memories of his mother and father. He had love, and they took it from him. He should be a killer. He should want to tear the world apart for what it did. And yet he took that pain. That shock of death. And he turned it into hope.'"
 * "- Superman"

Bruce Wayne (better known by his superhero alias Batman) is a major character in the DC Comics franchise, created by Bill Finger and Bob Kane. He's a wealthy American playboy, philanthropist, and owner of Wayne Enterprises. After witnessing the murder of his parents as a child, he vowed to devote his life to ridding his native Gotham City of crime, an oath tempered by a sense of justice. From youth to adulthood, Wayne trained himself to near-perfect physical and intellectual conditioning and crafted a bat-inspired persona to fight crime.

Why He Rocks

 * 1) He's one of the most iconic superheroes ever made. Not just for DC, but for comics in general.
 * 2) He's living proof that mortals can be just as capable heroes as super-powered heroes, as he's been relaying on his combat fighting skills and intelligence, and doesn't have super powers, like most other supers.
 * 3) Billed as the "World's Greatest Detective," he can solve any mystery that enemies leave behind, whether he's searching for the enemies or anything relating to them.
 * 4) He has a strict no-kill policy in which no matter dangerous the foe he's facing had proven to be, he's never killed any of them. Proving he's willing to show mercy for the wicked.
 * 5) He has a legendary rogues' gallery with villains he's faced including but not limited to: the Joker, the Penguin, Harley Quinn, the Riddler, Scarecrow, Bane, Two-Face, Catwoman, Clayface, Killer Croc, Solomon Grundy, and more.
 * 6) One of his traits is that he let villains do what they usually do, but Batman uses that to his advantage to beat them.
