far enough and that the criminal needed to die. Five years after his parents' death, the Joker waged war on Gotham City, leading an endless army of criminals to attack Gotham. After watching some of his men burn down a comic book store, Bao finally decided to take matters into his own hands and became the Clownhunter. Using a baseball bat with a batarang attached to the end, he patrolled the Narrows and killed roughly twelve of Joker's men during the war. With the aftermath of Joker's defeat, Batman confronted Boa at his room. Having heard that he'd been forced to fight his parents zombified bodies during one of the fights, Clownhunter berated the Dark Knight for destroying their bodies and for not killing the Joker directly. In response, Batman told him to give up the vigilante path and gave him the contact details of Leslie Thompkins, warning him that he'd be arrested if he killed any more of Joker's thugs.
