Kakistos

Kakistos was a master vampire on Buffy the Vampire Slayer during season three. He was played by Jeremy Roberts.

Kakistos traveled to Sunnydale to hunt down Faith. The two had already faced each other in a fight that resulted in the death of Kakistos' pet alligators and him receiving a massive scar that ruined his right eye. In retaliation, Kakistos murdered Faith's first Watcher before a horrified Faith, who escaped to Sunnydale hoping to avoid Kakistos.
