Nefarious
"With the clock under my control, I'll be able to wrong all the rights in the universe. Every villain who has ever stumbled will get a do-over. Every protagonist's triumph will be reversed! Until, finally, a new present is created... in which the heroes always lose!" —Dr. Nefarious' plan to remake history with the Great Clock[src] Doctor Nefarious was a robotic mad scientist who hated organic life forms, despite formerly being one himself. He was the archenemy of so-called "superhero" Captain Qwark, and later the most recurring nemesis of the courageous duo, Ratchet and Clank and is the antagonist of the Ratchet and Clank series. Nefarious was the main antagonist of Ratchet & Clank: Up Your Arsenal, plotting to turn all organisms into robots, much like what happened to himself. He was eventually defeated, but survived. He made a number of cameos in further games, and finally returned as the main antagonist in Ratchet & Clank Future: A Crack in Time. He planned to gain control of time itself and remake history. He was again defeated, retreating into hiding after being rescued by his servant, Lawrence. He was then searched for all throughout the Polaris Galaxy by Galactic President Qwark (who took a great deal of credit for his defeat despite not being of much help to Ratchet and Clank), mentioned numerous times in the comic miniseries. He is set to reappear in Ratchet & Clank: All 4 One as a playable character along with Ratchet, Clank and Qwark.
