Black Mask disguises himself as Orpheus, and as such is forced to battle Zeiss, who was sent to kill Orpheus and other 'crime bosses' by grief-stricken Henry Aquista. When Batman arrives on the scene, he gets the better of Zeiss, but is distracted by a large explosive planted by the assassin which he must defuse. As he does, Black Mask deliberately allows Zeiss to escape. Through Onyx, he arranges for the transportation of a large machine for dispersing gasses, and then listens in as Batman gives his allies and police their orders for a final showdown with the gangs in Robinson Park.
