Mister Trick

From Multiversal Omnipedia

Mister Trick was a technology-savvy vampire who originally worked for Kakistos. After Kakistos' death, the ambitious Trick became leader of Sunnydale's vampires, and then allied with Mayor Richard Wilkins.

He organized such plots as "Slayerfest '98" and Ethan Rayne's mentally-devolving candy. He was eventually staked by Faith, who took his place with the Mayor.
