Batman Beyond: Return of the Joker (2000)|Full movie k33

A new faction of the Jokerz gang—consisting of Bonk, Woof, Ghoul, Chucko, and the Dee-Dee twins—attempts to steal high-tech electronic equipment but are intercepted by Batman (Terry McGinnis), the protégé of the original Batman, Bruce Wayne. The gang reports back to their leader, revealed to be the Joker, Bruce's arch-nemesis who has been presumed dead for decades. The Joker kills Bonk for his defiance and to intimidate the other members. Later, the Jokerz attack a press conference commemorating Bruce's return to Wayne Enterprises and the Joker reveals himself to Bruce, who insists that it cannot be him. After fending off the attack, Terry demands information from Bruce and Gotham City Police Department's Commissioner Barbara Gordon, the former Batgirl, but neither gives him answers. Not wanting Terry to face the Joker, Bruce orders him to return the Batsuit so he can investigate his old enemy on his own despite the limitations of his age. However, the Jokerz attack Terry, nearly killing his girlfriend Dana Tan, while the Joker poisons Bruce and his Great Dane, Ace—revealing he knows Bruce was Batman and that Terry is his successor. After Terry saves Bruce's life with an antidote, Barbara finally explains the Joker's disappearance; four decades ago, sometime following the departure of Nightwing (Dick Grayson) from Gotham City to Blüdhaven, the Joker and Harley Quinn kidnapped his successor Tim Drake, then Robin, while he was on patrol, inflicting three weeks of torture and brainwashing on him at the abandoned Arkham Asylum to learn Batman's secrets. When Batman and Batgirl found Tim, he was rendered manic catatonic by the Joker's chemicals to become a miniature version of the Joker. A fight ensued, during which Tim regained consciousness, then turned on and killed the Joker, suffering a complete nervous breakdown, while Harley fell down a ravine and was presumed dead. After Tim was treated with antidotes, he recovered a year later with help from Wayne family friend Leslie Thompkins. Bruce forced Tim to retire from superheroics, as he blamed himself for Tim's ordeal. Tim severed ties with Bruce and left to make it on his own in life.
