Batman: Bad Blood

Batman: Bad Blood is a 2016 American animated superhero film which is the 25th film of the DC Universe Animated Original Movies and the sixth film in the DC Animated Movie Universe. It serves as a sequel to the 2015 film Batman vs. Robin. The film was released on January 20, 2016, for iTunes and the Google Play Store, and on DVD and Blu-ray on February 2. While not a direct adaptation of a particular storyline, it derived from Grant Morrison's run on Batman, primarily the Leviathan story arcs.

Jason O'Mara, Sean Maher, and Stuart Allan reprise their roles from the previous films as Batman, Nightwing, and Robin, with Morena Baccarin returning from Son of Batman as Talia al Ghul, while Yvonne Strahovski joins as Batwoman.

Six months after the defeat of the Court of Owls, Batwoman intercepts a crowd of criminals in Gotham City that includes Electrocutioner, Tusk, Firefly, and Killer Moth. When a fight ensues, Batman arrives. They are confronted by the apparent leader of the criminals, a masked man calling himself "Heretic", who reminds Batman of his vision of Damian Wayne as Batman. Alongside his subordinate Onyx, Heretic detonates explosives planted within the facility. Batman flings Batwoman to safety and apparently dies in the explosion.

Two weeks later, a concerned Alfred Pennyworth sends a distress signal to Nightwing. Meanwhile, at a monastery in the Himalayas, Bruce's twelve-year-old son Damian Wayne watches a news report of Batman's disappearance and sets out to return to Gotham. Batwoman's civilian alter-ego Katherine Kane meets with her father Colonel Jacob Kane explaining she feels responsible for Batman's apparent death, as his sacrifice reminds her of the childhood trauma she still carries. In the past, Katherine, her sister Elizabeth, and her mother Gabrielle were abducted and held for ransom. When her father attempted to rescue the three, both Beth and Gabrielle were killed, leaving Kate as the sole survivor. Kate later joined the military, but was discharged for unstated reasons. After her expulsion, she began frequenting nightclubs and overindulging in promiscuous sex and drugs. One night as she left a nightclub in a heavily impaired state, she was attacked, but was saved at the last minute by Batman. This experience motivated her to become Batwoman.

Batman apparently resurfaces and is quickly noticed by Robin and Katherine. Both of them intercept Batman and deduce that it is Nightwing wearing an older version of the Batsuit. They begin their own investigations into the Heretic, unconvinced that Bruce is truly dead. 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 he 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, revealing himself as 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 to feel like a real person, but Talia arrives and kills him for defying her orders, much to Damian's anger. Nightwing and Batwoman then arrive, having located Damian through a tracker in his costume. They are joined by Luke, clad in an exosuit designed by his father and styling himself as Batwing. The three rescue Bruce and Damian, but Talia and most of 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, 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 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 Calculator is killed by Alfred, interrupting the mind control and killing the Mad Hatter in the process as well. Bruce, still brainwashed, defeats Nightwing. Talia orders him to kill Nightwing and Damian, but thanks to a speech Nightwing gave, Bruce resists the brainwashing. Incensed, Talia escapes in a vessel only for Onyx to confront and attack her to avenge Heretic's death. The vessel crashes and explodes, with the two being presumed dead. 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.
