Jack Forton

Jack Photon is the strongest member of the werewolf clan (after Mizen Forton, the clan leader). He is second-in-command of the Photon household. He hates humans. The scar on his face is one that was left by Nine.

Werewolves (in general)
For clarification, "Photon" is a collective surname that all werewolves use. Werewolves are able to recover from most injuries, however, if another werewolf harms them it'll leave a scar. Werewolves and mages use different kinds of magic, so when one group uses their magic on the other it can cause deep bodily harm due to the different magic conflicting with each other.
