Y'know, maybe Drek was right. I am a mad scientist.
~ Dr. Nefarious

Dr. Nefarious, also called Neffie (by Drek), and jokingly called "Steve Nefarious" by Zed, is the main antagonist of the 2016 PS4 reboot video game of Ratchet & Clank as well as the game's movie adaptation from the same year. Much like his original counterpart, Nefarious is an unstable mad scientist and the archenemy of Ratchet and Clank, this version is much more evil, however.

He was voiced by Armin Shimerman, who also portrayed Letek in Star Trek: The Next Generation.


Dr. Nefarious was a highly insane, twisted, unstable, and psychopathic scientist. He even went as far to destroy his former boss, Chairman Drek, and proved to be even more psychotic and dangerous.


Doctor Nefarious was a mad scientist and former Galactic Ranger, who manipulated the Blarg Chairman in order to gain vengeance.

At the end of the movie he survives the destruction of the Deplanetizer, albeit seriously injured.

Small robots called Repairbots who passed by transformed him into a robot, despite his protests. Nefarious lifted himself up and realized his new body actually was that of a robot, although he did not want it and broke into a devilishly hysterical and then maniacal evil laugh.


No! Get away from me! not stick that thing in… (yelps and screams in pain) Quit…trying to repair me, you moron! (groans and grumbles in pain as Repairbots leave, then grabs one and pulls himself out) I AM NOT A ROBOT!!! (looks down at hands and starts laughing) Hehehehehahaha… Hahahahahahaha…Hahahahahahahahahaha!
~ Nefarious' Villainous Breakdown and evil laugh in the mid-credits scene of the 2016 film.



  • Nefarious's new personality in the reboots have gained quite a lot of criticism from fans, due to sharing very little similarities to his original counterpart, being a mad scientist actually being one of the few things they share in common.
    • Which has also lead some fans into comparing the original Chairman Drek to the new Nefarious and the new Drek being more similar to the original Nefarious.
