Orpheus

Gavin King always loved martial arts and dancing. He eventually joined a professional dance troupe, and traveled the world. In his travels, Gavin witnessed much poverty and violence, and vowed to do something about it. He joined a secret organization which provided him with the training and equipment needed to combat crime in Gotham.

Batman was wary of Orpheus at first, but the two quickly became allies in their war on crime. Orpheus was one of the centerpieces of Batman's plan to unite the gangs of Gotham but before this plan could succeed, he was killed by Black Mask.
