Following the defeat and disappearance of Dr. Nefarious, Klunk returned to his homeworld, Mariona. Here, he built two mechanized suits: Robo-Nefarious, and Robo-Ratchet. He had also built the Kingpin suit on Jorsey to disguise himself as a crime lord. He then stored his three suits in his base on Planet Hydrano. Robo-Nefarious was designed to duplicate Klunk's creator, and possessed new abilities based on the doctor's own abilities. Klunk also apparently took pleasure in acting as a superior and giving orders to a substitute of his maker, finding the experience fun and quite therapeutic. When Klunk's use of the Kingpin disguise was finished, the three suits together would be utilized in Klunk's soon-to-be final battle with Agent Clank.
