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. 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. 

Dementor employs a staff of henchmen, supposedly supplied by HenchCo. He has no other known allies, and hasn't teamed up with other villains in the past. Dr. Drakken is a sworn enemy of Dementor; they frequently attempt to steal the same valuable technology, sometimes from each other's lairs. He is a foe of Kim Possible; in their first meeting she was tricked into stealing the Transportulator from his lair by Dr. Drakken, and their relationship has only gotten more hostile from there. It was Dementor that cracked the secrets of Kim's Battle Suit and turned its power against her.

Talents and 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.
