Bruce Wayne, known by his alter-ego Batman, was a millionaire businessman who masqueraded as a bat in order to fight crime in Gotham City.
Batman Begins
As a young boy, Bruce was good friends with Rachel Dawes. He fell down a well and was attacked by bats, and his father, a doctor, rescued him. Later they attended the opera with his mother and as they left they were confronted by Joe Chill, who mugged and then shot both of Bruce's parents. Orphaned, Bruce was cared for by the family butler Alfred Pennyworth. He attended Princeton University, then returned to Gotham as Joe Chill was being released in exchange for information on Carmine Falcone. Bruce waited outside the courtroom to kill Chill, but one of Falcone's assassins got to him first.
Robbed of his revenge, he was admonished by Rachel Dawes for being so selfish. He confronted Carmine Falcone, who told him that he would never be able to face up against criminals as he didn't understand their world. Bruce then got on a ferry and travelled over Asia, becoming part of the criminal underworld. He was eventually arrested and sent to jail, where he brawled with the inmates. A man called Henri Ducard told him that if he climbed a certain mountain he could become part of the League of Shadows.
Bruce was released and journeyed up the mountian. There a man claiming to be Ra's al Ghul trained him in martial arts and deception, and he became a leader of the League. However, when asked to execute a convicted murderer Bruce refused, setting fire to the building and escaping. Before he left he saved Ducard's life.
Bruce then returned to Gotham and set about trying to combat criminals. After discovering Lucius Fox's R&D department at Wayne Enterprises he built himself a batsuit and many gadgets and weaponry. He enlisted the help of Jim Gordon, a police officer, in order to track down and capture Carmine Falcone, and deliver him to the police.
After Falcone was imprisoned, Bruce investigated what he was smuggling in. He was attacked by the Scarecrow, who sprayed him with fear toxin. Bruce realised Rachel Dawes was in danger from the Scarecrow and rescued her from Arkham Asylum. He made it back to his birthday party in time, but Henri Ducard was waiting, revealing himself as the real Ra's al Ghul. Ghul burnt down Wayne Manor and left to destroy Gotham with a microwave emitter.
Alfred saved Bruce from the fire, who then went to The Narrows to face Ducard. He cornered him on the monorail and refused to save him as the monorail crashed into a building. The city was saved and Batman revealed his identity to Rachel. Batman then met with Jim Gordon, who told him crime was escalating and a new enemy was on the loose.
Batman: Gotham Knight
Bruce Wayne continued to serve justice as the Batman. There had been reports of people being attacked by
The Dark Knight
an 8-foot-tall reptilian creature. Batman was certain that the Scarecrow's fear toxin was connected with these incidents and began an investigation in the sewers. Batman was suddenly attacked by the monster, Killer Croc, who had been injected with Scarecrow's fear toxin, thus infecting Batman with it. He defeated Croc and made his way deeper into the sewers where he encountered and confronted Scarecrow. He flooded Scarecrow's chamber and escaped with Cardinal O'Fallon, and Scarecrow just barely escaped.
An assassin named Deadshot, who took great pride in his work, was hired to assassinate James Gordon in an attempt to take out Batman. Batman managed to outsmart the assassin, and he realized that there are some criminals he may never understand, and whose lines he would never cross.
The Dark Knight
As the Joker wrought havoc in Gotham, Bruce tried to keep track of his whereabouts. Along with Harvey Dent, the new District Attorney, they managed to track down the mob's money to a man called Mr Lau. Bruce travelled to Hong Kong to capture Lau and deliver him back to Gotham, where he implicated the rest of the mob in a Reco case.
However, the Joker sent a tape telling Batman that if he didn't reveal himself people would die. Commissioner Gillian Loeb and judge Janet Surrillo were killed, and the Joker invaded a party where he tried to capture Harvey Dent and Rachel Dawes, his new girlfriend. However Batman saved Rachel and Harvey. Next, at the memorial for commissioner Loeb, the Joker and his men shot at Mayor Anthony Garcia, and Batman stopped Harvey Dent from killing one of the Joker's men. Batman then agreed to give himself up, but before he could Harvey Dent told the press it was him.
Bruce then tailed Harvey's police escort and saved him from the Joker. He confronted the Joker on the street, but couldn't kill him. Just as the Joker was about to kill Batman, Jim Gordon revealed himself and arrested the terrorist. Batman then interrogated the Joker after Harvey Dent went missing. The Joker revealed he had captured Harvey and Rachel, and gave Batman their locations. Bruce went after what he thought was Rachel's location, but in fact was Harvey's. Batman saved Harvey, but half of his face was burnt away. Rachel was killed, and the Joker escaped.
Bruce then faced trouble as Coleman Reese threatened to reveal his identity, but the Joker ordered Reese's death. Bruce saved his life, but then had to face the Joker's next threat - two ferries loaded with explosives. Batman broke into the Joker's building were hostages were being held and captured the Joker. The ferries did not explode, but the Joker revealed his true plan - he had turned Harvey Dent insane.
Batman rushed off the building where Rachel had died to find Dent holding Jim Gordon's family hostage. He flipped a coin for each of their lives, shooting Batman in the chest. Just as he was about to kill Gordon's son, Batman attacked Dent and threw him off a ledge. Batman and Gordon agreed that the story of Harvey's madness should not leak out, and Batman would be branded a villain who killed Dent. Batman drove off into the night.
