Carter was a Watcher who was corrupted by James Horton, who convinced him that Immortals were abominations bent on subjugation of mortals, and must be destroyed. Like Horton, his vocation warped into that of a Hunter. He used his position as an officer of the Seacouver Police Department to this end when possible. Later he hunted Carl down, armed with his ax and a shotgun. He threatened Carl, when suddenly Duncan MacLeod and Carter's partner, Kenneth Dixon, showed themselves. Ordered to stand down, Carter tried to use his weapon, and was shot by Ken. He fell to his death in the harbour.
