Cormac was a resident of Fort Bailey in the 19th century and appeared in Ginger Snaps Back: The Beginning.
When Brigitte and Ginger Fitzgerald first arrived at Fort Bailey accompanied by the Hunter, Cormac was in charge of watching the gate and let all of them pass without saying a word. He was immediately reprimanded by James for letting the two unknown girls in. On the day after the hellhound attack, he helped Claude to throw one of the dead werewolves onto the pire.
When a half-transformed Geoffrey Rowlands showed up on the cemetery, mourning on his mother's grave, Cormac fired a shot at the grotesque looking boy, hitting and damaging the tombstone of his alleged grave.
When a transforming Ginger later returned to Fort Bailey to get her sister back, Cormac was tasked with watching the gate again. This time being told to let her in so the men inside could kill her. Being overconfident, James approached her and was quickly killed by a slash to his neck. She then let the hellhounds in who quickly dispatched Cormac and Claude, mauling them to death.
