"Finding Mr. Right"
While Harley Quinn was aiming to make Batman her arch-nemesis, she ended up finding Robin instead. Harley refused to fight him since he was a kid, and walked away. The next day on the news, Damian makes up a story about how he fought and beat Harley, much to her fury. Harley tries to kidnap Lois Lane to attract Superman, who does come, but he lets Robin handle the situation once he comes in. However, once Superman leaves Harley has no interest in fighting Robin and walks away from the whole thing.
Eventually, Harley plans to make Robin confess that they aren't arch-nemeses. He gets hung by a rope over a tank of water, where King Shark would try scaring him into confessing that they aren't really enemies. Robin talks to Harley about how as the "sweet potato pie" of Gotham, everyone believes everything he says, but the newscasters were secretly recording and airing this confession. Damian is angry at this trick, but soon gives up. However, his nosebleed, a problem he had shown throughout the episode, soon drips blood into King Shark's tank, driving him into a violent rampage.
Harley Quinn fights against King Shark to try calming him down, which attracts Joker's attention. He comes in to try killing Harley, and Poison Ivy comes in to protect her, the newscast trying to interview everyone coming in. Eventually, King Shark is after Robin, who calls out for his father, Batman, to save him. Once he finally gets there, Batman sprays King Shark with the shark repellant which knocks him out. They soon escape to the Batcave to have a talk and Batman opens up about not having a nemesis until his late 20s.
With Batman missing, Robin steals his outfit and attempts to "take up the mantle" of Batman, only for Jim Gordon to mock and dissuade him. Nevertheless, he did manage to let Gordon know of Batman's disappearance, and confirmed that Batman was not responding to his texts (although he refused to share the contact info with Gordon).
- This version of Damian seems to not be as prepared for crime-fighting as the main continuity version, since he was calling for help immediately after he realized he was in danger. He also seems not to care that much about secret identity, since he called Batman in front of TV cameras "Father" and "Dad".
