Nefarious

Dr. Nefarious was voiced by Armin Shimerman.The villain of Ratchet & Clank: Up Your Arsenal, Dr. Nefarious is a stereotypical robotic mad scientist who has a hatred for "squishies", despite formerly being one himself.

History
He and Captain Qwark have a deep history going back to when they were in high school where Qwark, being bigger and older (he was 26, according to Nefarious), bullied and humiliated him. His plan was to use the Biobliterator, a superweapon that turns all organic life into robots, to convert all under his "benevolent, iron-fisted rule".

Future
In the end, he ends up getting stuck on an asteroid with his servant Lawrence, unable to get out of their location (for 5 to 10,000 years, according to Lawrence).

Overload
He has a strange habit of overloading in times of extreme stress, causing him to freeze up and pick up random signals of a soap opera in his head. Early on in the game, it is also revealed that Nefarious is Clank's biggest fan, thinking that the Secret Agent Clank series are real.

Still Stuck
He makes a cameo appearance in Deadlocked alongside Lawrence still stuck on the same asteroid only to arrive at the ruins of the DreadZone Station, so he would remain stuck until something else came along, hopefully not in 5 or 10,000 years.
