Red Hood

Intro Jason allied himself with Scarecrow and Deathstroke, and planned to destroy both Batman and Gotham. After he unmasked himself in front of Batman, and after he saw how much that Bruce still cared about him, Jason decided to help Batman, instead. He took on a new name, and became a vigilante once more, albeit with extreme tactics, and tried to put an end to crime under the identity of the Red Hood. He tracked Batman's movements to the abandoned Arkham Asylum and freed him from Scarecrow. Jason Todd was still killing but now only to criminals as the Red Hood after the global revelation of Batman's identity as Bruce Wayne. At some point, he allegedly killed Killer Moth, Black Spider and the Clock King among other villains. He also ran Sal Maroni out of the city for good, thus ridding Gotham of the last remnant of the old organized crime ways. Jason then hunted down Black Mask and slowly took down his gang. Always leaving one member for interrogation before shooting them, Jason learns of Black Mask's operation at the docks, and kills all his men there, before going to his office downtown. He enters the building (involving kicking the door down and taking out the four entrance guards in a matter of seconds) and proceeds to wipe out the goons in the room. Black Mask is alerted to his presence, and barges in with backup, stating Red Hood made "a big mistake comin' here". After dispatching the goons, and sufficiently weakening and beating Black Mask down, Jason picks him up and slams him against one of the rooms large windows while telling the crime lord that he should have left Gotham when he had the chance. Black Mask begs for his life, offering "Drugs, Guns, anything you want" but makes the mistake of saying he'll go anywhere he wants, Jason suggests "How 'bout you go to Hell?" and proceeds to forcefully kick him out of the 3-story window onto the street Jason then quips: "Say hi to Joker for me."
