Batman
In the more popular Batman film directed by Tim Burton, The Joker is the main antagonist and is portrayed by Jack Nicholson. His name is Jack Napier in the film. Napier was born in Brooklyn, and at school he proved unstable but highly intelligent. He turned to a life of crime when he was older and was convicted of assault at age fifteen.

When Napier was older, he became a criminal. He and his partner mugged a young Bruce Wayne's parents, Thomas Wayne and his wife Martha. When Thomas attempted to protect his family, Jack shot both of them in cold blood, and came out of the shadows and pointed the gun at Bruce. Before he could shoot, his panicked partner convinced him to leave so they could get away. Jack taunted Bruce before leaving him. The experience eventually caused Bruce to become a crime fighter under the name of Batman.

Napier had become the right-hand man of crime lord Carl Grissom. Napier would often toy with a deck of cards. Napier had an affair with Grissom's girlfriend Alicia Hunt, and when Grissom found out, he set Napier up to be killed by a corrput policeman Lt. Max Eckhardt at the Axis Chemicals. Grissom tricked Napier into entering the Axis Chemicals by informing him that he had to steal documents from the plant. The plan failed when Batman entered the scene to capture his parents murderer, and during the fight, Napier killed Eckhardt and tried to escape, followed by Batman, and the criminal tripped and plummetted into a vat of chemicals. His appearance was altered by the chemicals, his skin turning white, his hair turned green, his lips became red, and he had a permanent smile.

Napier lived and was washed into Gotham Harbor by a drainage pipe. Submerged, he stretcehd an arm upward through the water. He soon realized the effects of the chemicals. He tried to get his face fixed by a plastic surgeon, but he failed to fix his permanently disfigured face. Napier tried to let go of what had happened to him, but that failed too. Losing whatever sanity he had left, Napier renamed himself the Joker, declaring that Jack Napier was dead now. He murdered Grissom as revenge for setting him up and went on a crime-spree to outdo Batman. In a metting with the other crime lords, the Joker lied and said Grissom wasn't dead and was just hiding and had ordered him to run Gotham. One of the crime lords, Antoine Rotelli, was suspicious of the Joker, so the Joker terminated him by giving him a hand-shake and electrocuted him with a joy buzzer, horrifying the other criminals. The Joker's minions came out and held the mob bosses at gunpoint. The Joker then murdered Roscoe at City Hall after claiming he was his Uncle Bingo. The Joker took an interest in reporter Vicki Vale and gassed everyone in the building to death except her so he could woo her. At that moment, Batman burst through the ceiling window to rescue Vicki, but the Joker escaped.

The next day, the Joker surprised Bruce Wayne and Vicki Vale and shot Bruce, who survived because he was wearing a bulletproof vest. Batman discovered that the Joker was actually the gunman who killed his parents, and seeked revenge. The Joker had another plan in store, and he paraded out in the streets and threw twenty million dollars everywhere, and the citizens of Gotham rushed out to grab it. The Joker then made a speech while they took the money that he would relieve them of their lives, but they didn't listen. The Joker then released Smylex gas out of his balloons and those taking the money were killed. Batman arrived in the Batwing to save them and kill the Joker in revenge. Taking away the balloons, Batman then fired at the Joker, who shot back with a long barrelled gun and destroyed the Batwing. The Joker kidnapped Vicki and danced with her at Gotham Cathedral while Batman fought his minions and defeated them easily. Batman snook up on the Joker and attacked him, beating him with his bare hands. During the fight, The Joker, Batman, and Vicki fell from Gotham Cathedral, and the Joker tried to knock the two off the ledge they were hanging from. His minions flew a helicopter to the Cathedral and threw down a ladder, and the Joker was about to climb up when Batman tied his leg to a gargoyle that broke loose. The Joker was pulled down by the weight of the gargoyle and fell and died from the fall. Commisioner Gordon and the cops came and found his body.
