Professor Dementor

Professor Dementor is a supervillain and mad scientist in Kim Possible, who seeks to dominate the world. He is a sort of foil to Dr. Drakken, as they are similar in villainy style, but Dementor seems to be more famous and successful. His real surname is Demenz (the German word for dementia), his first name is unknown.

His voice is performed by comedian Patton Oswalt.

History
Little has been revealed of Dementor's past or origin. He was apparently well-known as a supervillain before Drakken became a high-profile evil-doer; a running gag from the earlier seasons has others confuse Drakken for Dementor, much to the former's chagrin.

Description
Dementor has something of a Napoleon complex, and is quick to anger. He generally follows a pattern of gloating, followed by exasperation, with a course of ranting to follow. He has an over-the-top German accent.

He wears a distinctive black mask, brown trousers, and a red coat.

Skills
Dementor is a better scientist than Drakken, and he is also capable of stealing devices for his own needs. His henchmen are of superior quality, as well. Kim generally has to work hard to foil Dementor.
