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 defining tactics when fighting evil is to let villains do what they usually do, but then use that to his advantage to beat them. This is known in popular culture as the "Batman gambit".

Bad Qualities
1. He is flanderized in the DCEU movie Batman VS Superman: Dawn of Justice, where he was made into an angry, paranoid, cynical psychopath who spends over half of an entire movie planning to kill Superman, all for the sake of being edgier than his other version in The Dark Knight. But he redeemed himself in Zack Snyder's Justice League, where he is more gentle and in line with his comic book counterpart.
 * 1) *He also flanderized in All-Star Batman and Robin and The Boy Wonder, who became more unheroic and sociopathic than the hero himself. which made every fan hate him and massive negative reviews/comments from the critics.
