Buck Cowan was the closest friend of Jack Russell and one of the few individuals who knew he suffered from a curse that forced him to transform into a werewolf. Jack would often ask Buck to lock him up at his house during full moon nights. At one point, Jack provided Buck with a gun loaded with silver bullets to put him down if necessary, but when Jack broke out in his werewolf form, Buck couldn't bring himself to shoot his friend.
Buck was targeted by Atlas, a former actor who had become horribly disfigured in an accident on a movie written by Cowan. He was saved by Jack and when Atlas was about to kill the werewolf, Buck shot and killed him.
Buck was almost killed by Russell in his werewolf form when he tried to protect little Buttons Marston who had become lost in a snowstorm and enountered the werewolf.
