of run-ins with the Gotham City Police at age fourteen, while his parents were going through a divorce, even serving a three-month stint in juvenile hall. Twenty years after Batman's disappearance from Gotham, due to Bruce Wayne's retirement on account of a cardiovascular disease, Terry finds himself on the run from the Jokerz, another street gang, who have modelled themselves after the long-dead legendary criminal, the Joker. Terry flees onto the grounds of Wayne Manor, where an aged Bruce comes to his defense and together they subdue and ward off the Jokerz. The strain of the fight places substantial stress on Bruce's weak heart, so Terry helps Bruce into the mansion and gets him his medication; Bruce proceeds to fall asleep afterward. Terry attempts to leave, but Bruce's dog Ace stops him with hostility. He then tries to call his father but then notices a bat stuck inside a grandfather clock. As he tries to free it he stumbles upon the entrance to the Batcave and realizes that the elderly man was the city's heroic Dark Knight. He is then forced out by an enraged Bruce. Terry returns home to find his father murdered, ostensibly by the Jokerz. He later discovers that Derek Powers (who has assumed leadership of a merged Wayne-Powers) ordered Warren's death after the latter discovered Powers' plan to mass-produce biological weapons. Powers' right-hand man, Mr. Fixx, leads a raid on the McGinnis home and shoots Warren McGinnis. (In the comic books, he orders one of his henchmen, Jake Chill, who is a great grand-nephew of Joe Chill, the one who murdered Bruce's parents, to shoot Warren). Terry then seeks Bruce's assistance in bringing Powers down, but cannot convince the old man to inflict swift justice - Bruce is still shaken from an ordeal 20 years earlier of having relied on a handgun for self-defense (the event that forced him to retire as Batman for good), as well as the traumatic event of the Joker's death and Tim Drake's psychological torture in the flashbacks of Batman Beyond: Return of the Joker. Bruce suggests that Terry take the evidence against Powers to the current commissioner of police, his former partner Barbara Gordon, the retired Batgirl, but after a scuffle with Powers, during which Derek can reclaim the evidence, Terry takes matters into his own hands and steals the Batsuit. Despite some initial mistrust, their similar backgrounds convince Bruce
