In "Spiral" the leader of the Knights of Byzantium. After their attack on the Scooby Gang in the Winnebago, The General is taken captive inside an abandoned gas station protected by a magic protection spell cast by Willow. While tied to a post, he explains (for the first time) the history of "The Beast" (Glory) and the true significance of The Key which his order has sought for centuries to destroy.

When Ben morphs into Glory, Gregor is killed by a hubcap she throws like a frisbee into his chest.
