Claw was once a human whom Dr. Sevarius mutated at some point. The trauma from the metamorphosis, physical or otherwise, rendered him mute.
Claw lived with the other mutates for some time with Xanatos, until the connection between Xanatos and Sevarius was revealed. After that, he moved to the Labyrinth, where Fang bullied him into submission. After finally standing up for himself, Claw guarded the homeless residents of the Labyrinth with the other mutates.
When Thailog stormed the Labyrinth to reclaim the clones, Claw made a stand, and attacked Thailog, but he was held back by the clones who had quickly succumed to Thailog's will.
Claw has all the typical characteristics of a mutate; bat wings that enable him to fly, a feline body giving him superhuman strength, and an electric eel's ability to create electrical charges. The source of the feline DNA used to create Claw was a tiger (Panthera tigris).
Despite his shy demeanor, Claw is physically the strongest of the mutates, perhaps even stronger than Wolf. He even managed to wrestle Thailog to the ground briefly, though he was roughed up by that encounter. ("Masque")
As for his personality, Claw tends to be somewhat cowardly and timid, though he shows the potential for change. He appears to be suffering from a case of PTSD, as he has not spoken since his transformation.
