He is summoned by Lincoln to track down Emperor Zombie, an undead occultist and originally a groundskeeper at Hyde Park.

This will allow him access to the temple of Gung, a warlord who nearly conquered the world over ten thousand years ago with supernatural power gained from "a fabulous melon-sized jewel", which Zombie obviously plans to use for himself.

Out of revenge for his first defeat, Zombie developed what he refers to as a "petty vengeance fetish", killing the seven replacement servants after him, and before Mr. Groin (Patton Oswalt), in gruesome ways.

On August 20, 2006, The Amazing Screw-On Head TV pilot was aired online at scifi.com with a survey to decide whether or not the show went to series.
