The villains' origins
Dr. Belljar- One in a series of cyborgs, much like Robocrook in World. That's why he looks different in Season 2- it's a different model.
Jacqueline Hyde- Girl with Dissociative Identity Disorder, went to Carmen for help but just made it worse. Works for Carmen in hopes she'll finally cure her (the good side's an optimist).
Medeva- Medieval witch cast into time, saved by Carmen during a trip into the time stream. Works for Carmen to enable revenge against those who defeated her.
Sir Vile- Good knight captured and bound to Carmen's will by Medeva.
Baron Wasteland- Recruited by Carmen during a time trip. In it for the money, of his own free will.
Bugs Zapper- Ditto to Baron Wasteland.
