The ravages of decomposition sometimes take their toll. While searching the many graves in the graveyard they found themselves, the Exterminals realized that most of the corpses have been reduced to dust, and dust doesn't do a very good job of killing Spectrals. Due to the lack of options, they had to make do. While searching, they found the 280-year-old corpse of a victim of the Great Spectral War, with only its head, brain, heart, and long Cadavian neck remaining. This was substantially more than most of the coffins they searched, so they revived him. He still was only a head and neck, however, so Peeyache used some scrap metal and knowledge he learned from Seelsteal to build him a robotic body, a "robody" if you will. With his new-fangled Robody, Cybusk is doing better than ever. He's gotten along with the Exterminals pretty well if you ignore the time he suggested that maybe the Spectrals weren't actually that stupid and evil if Seelsteal took the time to teach Peeyache the very detailed and intricate skill of constructing robots. That's how Cybusk lost most of his remaining teeth.
