Ultimate Batman, also known as Bruce Wayne is part of the Ultimate Universe in DC comics. He is an excellent martial artist and is tied with 3 other people for the title of Greatest Martial Artist. The others are: Ra's Ahl Ghul, Shiva, and Slade. His parents were killed when he was a child and on their grave he made a promise to make criminals pay but to never kill.
Billionaire Bruce Wayne lost his parents when a mugger killed them in an alley after seeing a movie entitled "The Ultimate Gray Ghost" based on the superhero of the same name who worked in Chicago. When his parents were killed, Bruce went into shock. He was rehabilitated but swore, on his parents grave, that he'd take vengeance upon criminals. He trained with martial artists around the globe, until he heard that the person who killed his parents had been caught.
When he entered the court room he saw a man with a white face and a wide red grin, with green hair standing before the jury. After the man had been sentenced criminally insane and was being driven to Arkham, Bruce broke in while wearing a mask and threw this man into the ocean and drowned him. After he saw what he did, he confessed his sins and went to train with the Gray Ghost.
When he returned to Gotham, he was frightened when he was down in a cave under his mansion, when a bunch of bats flew by him. He decided to adopt the name, Batman. He custom made a leather dark gray suit with armored gauntlets with 4 spikes on the sides, which could be shot out. He had matching boots with the same spikes. He made a leather mask and cape with "bat-ears" to make him look more menacing. He altered many of the Gray Ghost's lethal weapons and made them non-lethal. Criminals would forever remember the name Batman, and they would tremble when they heard it spoken...
