the main story, while Batman is following a League of Shadows assassin to find Ra's al Ghul. Robin explains that he was called by Alfred to assist Batman in Arkham City, but the latter declines his help and asks him to look after Gotham in his absence, as well as analyze a sample of the Joker's infected blood. Robin is a playable character with the addition of the Harley Quinn's Revenge DLC, set after the main story, wherein he rescues Batman after the latter is taken captive by Harley Quinn in Arkham City. Robin is also playable in the game's challenge maps, and has two alternate costumes: his classic Red Robin suit from the comics, and Dick Grayson's Robin costume from Batman: The Animated Series. Robin appears as a boss in the mobile game Batman: Arkham City Lockdown, set a few weeks before Arkham City. While attempting to apprehend Poison Ivy, who escaped from Arkham Asylum, he is placed under her mind control, and later forced to fight Batman when he arrives to capture Ivy. Batman ultimately defeats both of them and releases Robin from the mind control. Robin plays a major supporting role in Batman: Arkham Knight, voiced by Matthew Mercer. Throughout the game, both he and Barbara attempt to convince Batman to allow him to assist in taking down the Scarecrow, but Batman insists that Robin looks after the patients infected with the Joker's blood, whom they are keeping at their hideout at the abandoned Panessa Studios. Batman also tells Robin to work on a cure, but avoids revealing that he too is infected. When Harley Quinn and her gang attack Panessa Studios to liberate the patients, Batman and Robin team up to stop her, and in the process, Robin finds out that Batman is infected with the Joker's blood. Robin insists that Batman be locked up for his own safety and let him handle the Scarecrow, only to be locked up himself after Batman refuses, not wanting Robin to get himself killed. Near the end of the game, the Scarecrow kidnaps both Robin and James Gordon to force Batman to surrender to him. While Batman manages to subdue the Scarecrow, his secret identity is exposed to the public in the process. At the end of the game, Batman seemingly commits suicide to protect his loved ones, leaving Robin and Barbara to continue fighting crime in Gotham. Aside
