Jason allied himself with Scarecrow and Deathstroke, and planned to destroy both Batman and Gotham. Jason eventually escaped and began plotting his revenge against Batman under the alias of the Arkham Knight. Joker got Jason to hate Bruce, with the final straw being the fact that Batman took on a new Robin, which lead Jason to believe that he was simply replaced. Joker tortured and brainwashed him, while Batman stopped looking for Jason after Joker sent Batman a video of Jason's supposed death. But only a few months into his training, Jason decided to go after the Joker, which resulted in his capture at Joker's hands. Years after the events of Arkham Origins, Batman took in Jason Todd and began to train him as the second Robin. Sometime after this, the Red Hood case went cold. Commissioner Loeb later claimed that the Red Hood was 'run out of the city.' Batman also began to speculate whether the Red Hood was, in fact, one or several criminals that were using the moniker. His actions ended up costing Gotham City millions worth of paper bills, at least at the time the report was made. He also struck again some time later by taking $300K, which lead Kale to vow to capture and unmask the Red Hood, although some notes on the crime-board indicated that Batman wasn't sure if that was actually the Red Hood who had committed the crime. His schemes were detrimental enough in Gotham City for Mayor Hill to make the apprehension of Red Hood a high priority for the GCPD.

According to the information, in addition to the Red Hood's role in the Ace Chemicals heist, he also had undergone several daring heists and major scores against other targets. Outside of the Joker's presence in the plot (and his psychiatric evaluation), the Red Hood was alluded to the on the Crime-Board in the Batcave, listed under the 2nd row as case 152, as well as on a separate billboard. Incident Reports Before Arkham Origins Incident However, while he was once again aligned with his former mentor in wanting to rid Gotham City of its criminal contingent, Todd's willingness to take lives will forever keep them at odds. It was during this recovery that the Red Hood was born, and is implied to have become the permanent holder of the identity. Since Jason Todd changed the Arkham Knight persona, he was able to lay his long-rooted vengeance against Batman to rest, and began to heal the damage that Joker inflicted on him at Arkham Asylum. The Red Hood is most notorious as being the former identity of The Joker prior to his encounter with Batman. As indicated by the name, the criminal wore a red bowl-shaped helmet as a means of covering his identity, although it is strongly implied that the person wearing the disguise was always different. The Red Hood was the alias of a particularly infamous criminal active during Batman's early years as the Caped Crusader.
