Batman: Bad Blood (2016)

Batwoman intercepts a group of criminals in Gotham City that includes Electrocutioner, Blockbuster, Firefly, Killer Moth, and others. When a fight ensues, Batman soon arrives. They are confronted by the apparent leader of the criminals, a man called the Heretic, who reminds Batman of his vision of Damian Wayne as Batman.

Heretic detonates explosives planted within the facility. Batman flings Batwoman to safety and apparently perishes in the explosion. Weeks pass. Both Batman and Bruce Wayne's disappearances have not gone unnoticed - Alfred Pennyworth takes up the guise of Wayne in electronic communications using gadgets in the Batcave to maintain appearances, while sending out a distress signal to Dick Grayson. Meanwhile, Damian Wayne watches a news report of Batman's disappearance and sets out to return to Gotham. Katherine Kane meets with her father Colonel Jacob Kane revealing she feels responsible for Batman's apparent death and asks his help to track down Heretic. It is revealed that she was traumatized when she, her sister Elizabeth and her mother Gabrielle were abducted and held for ransom, although she was the only one not killed by her captors before her father rescued her. After her time in the military, she became a drunkard who was saved by Batman, the appearance of whom motivated her to never need to be saved again, resulting in her becoming Batwoman. At the same time, Batman, wearing a different Bat emblem, apparently resurfaces and is quickly noticed by Robin and Katherine Kane. Both of them intercept Batman and quickly deduce that it is Grayson wearing an old version of the Batsuit. They begin their own investigations into the Heretic, unconvinced that Bruce is truly dead. Soon the Heretic and his henchmen attack Wayne Enterprises, forcing Lucius Fox to open the way into the vault by threatening his son Luke Fox, a soldier recently returned from Afghanistan. Though Grayson and Damian quickly arrive, they are unable to prevent the Heretic from escaping with Wayne technology, and Lucius Fox is non-fatally stabbed. Before they leave, Heretic kills Electrocutioner when he is about to kill Robin. Heretic returns to his headquarters where it is revealed that he is working for Talia al Ghul. They have Bruce Wayne captured and Mad Hatter is slowly brainwashing him with a machine projecting laser like beams into his eyes and brain causing him to experience nightmarish visions of his parents and friends as well as several bats attacking him. Mad Hatter claims Bruce's memories and experience, as well as his mental and emotional trauma, is causing the mind-controlling process to take longer on him than normal. The Heretic, apparently obsessed with Damian Wayne, then breaks into the Batcave and kidnaps Damian. Heretic explains that he is a clone of Damian, created by a genetics program created by Ra's al Ghul and the League of Assassins, using Damian's DNA to genetically engineer a perfect soldier with accelerated growth and development, but he was the only subject of the program to survive with Mad Hatter giving him an actual mind and consciousness. Due to his feeling of not being a real person, he wishes to have Damian's memories and personality implanted within his own brain with the mind programming machine being used on Bruce, but Talia arrives and then shoots Heretic dead for his disobeying her orders to leave Damian out of the conflict. Grayson and Batwoman then arrive, having located Damian through a tracker in his costume. They are quickly joined by Luke Fox, clad in an advanced combat exosuit and styling himself as Batwing. The three rescue Bruce and Damian, but Talia and her henchmen escape. Weeks pass and Bruce seems to have recovered from the ordeal, though he remains adamant that Katherine and Luke not be involved, insisting that their heroics remain within the "family". Meanwhile, Katherine is suddenly attacked by her father. After disabling him, she discovers he had been brainwashed. She brings this to the attention of Grayson, Damian, and Luke. Dick immediately concludes that Bruce is still under the effects of Mad Hatter's mind control, though Damian is unconvinced. Luke reveals that the League of Assassins are planning to brainwash a number of world leaders at a tech summit held by Bruce Wayne with the use of advanced earpieces being distributed to the attendees. As the brainwashing is taking place, Nightwing, Robin, Batwoman, Alfred, and Batwing arrive and fight Talia and her henchmen. During the fight, Mad Hatter is killed, thus stopping the mind control from undergoing to completion. Bruce, under the effects of the brainwashing, is made to fight Nightwing and defeats him. Talia then orders him to shoot Grayson and Damian dead, but Bruce, with the help of Grayson's pleas, resists the effects of the mind control and disobeys her. Incensed, Talia escapes into her auto pilot vessel only to be met by Onyx, a member of Heretic's team who attempts to murder her in revenge for the ruthless death of Heretic, causing the vessel to crash, resulting in both her and the latter's death. The "Bat family" then returns to the Batcave to plan their next move. Nightwing explains that none of the Mad Hatter's programming can function without his being around to activate it. The Bat skylight shines in Gotham City where Batwoman, Nightwing, and Batwing assemble to meet Batman and Robin on top of the police station where they see Penguin escaping cops by car. Batwoman and Batwing fly down, as Batman, Robin and Nightwing fire their grappling guns. On a nearby building, Batgirl observes the group launch their chase and fires her own grappling gun to join the pursuit.
