Batman: Bad Blood is a 2016 direct-to-video animated superhero film that is part of the DC Universe Animated Original Movies and DC Animated Movie Universe. It serves as a sequel to the 2015 film Batman vs. Robin. The story features Batman, Damian Wayne aka the current Robin, Dick Greyson aka Nightwing and introduces Kate Kane as Batwoman and Luke Fox as Batwing.
Batwoman intercepts a crowd of criminals in Gotham City that includes Electrocutioner, Tusk, Firefly, Killer Moth, and others. When a fight ensues, Batman arrives. They are confronted by the apparent leader of the criminals, a masked man calling himself "the Heretic," who detonates explosives planted within the facility. Batman flings Batwoman to safety and apparently perishes in the explosion.
The absence of Batman after the explosion prompts Alfred to be worried and to cover for Bruce via video call at board meeting; Damian to leave his training at a monastery in the Himalayas to return to Gotham, and Nightwing to reconnect with Alfred and Damian and pretend to be Batman. The Heretic and his henchmen attack Wayne Enterprises, forcing Lucius Fox to open the way into the vault by threatening his son Luke. Though Nightwing and Damian arrive, they are unable to prevent the Heretic from escaping with Wayne technology, and Lucius is injured. Before they leave, the Heretic kills Electrocutioner when the latter is about to kill Robin.
The Heretic returns to his headquarters, where it is revealed that he is working for Damian's mother, Talia al Ghul. They are holding Bruce prisoner and the Mad Hatter is slowly trying to brainwash him. The Heretic breaks into the Batcave and kidnaps Damian. He explains that he is a clone of Damian, created by a genetics program run by Ra's al Ghul and the League of Shadows. He wishes to have Damian's memories and personality implanted within his own brain so that he can feel like a real person, but Talia arrives and kills the Heretic for defying her orders. Nightwing and Batwoman then arrive, having located Damian through a tracker in his costume. They are joined by Luke Fox, clad in an advanced combat exosuit designed by his father and dubbing himself Batwing. The three rescue Bruce and Damian, but Talia and her henchmen escape.
A week passes and Bruce seems to have recovered, though he remains adamant that Katherine and Luke should not be involved. After Katherine is forced to fight her father after he suddenly attacks her for no reason and having no memory of attacking her after she hit him in the head, Dick realizes that Bruce is still under the effects of the Mad Hatter's mind control. Luke realizes that the League of Shadows are planning to brainwash a number of world leaders at a tech summit held by Bruce. As the brainwashing takes place, Nightwing, Robin, Batwoman, Alfred, and Batwing arrive and fight Talia and her henchmen. During the fight, the Mad Hatter is killed, interrupting the mind control. Bruce, still brainwashed, defeats Nightwing. Talia orders him to kill Nightwing and Damian, but Bruce resists the brainwashing. Incensed, Talia escapes in a vessel, only for Onyx, a subordinate of the Heretic, to confront and attack her to avenge Heretic's death. The vessel crashes and explodes, implying their deaths. Bruce is later seen comforting Damian over Talia's supposed death. Alfred remarks to Dick that despite Talia's madness, she was still Damian's mother.
