He followed Talon at first, until they moved into the Labyrinth. With Talon refusing to call himself a leader, the greedy and aggressive Fang decided to take that role for himself. Along with a cowed Claw, he organized a gang of thugs, and after finding a cache of Cyberbiotics weapony, he made an attempt to take over the Labyrinth. This was stopped with the help of Brooklyn and the Manhattan Clan, after which Talon finally assumed a leadership role.
