Pretorius is a madman who had his own head removed from his body and placed on tiny, spider-like robotic legs, which could attach to a larger android body.
His plans always revolved around either obtaining or controlling the Mask of Loki (Pretorius is one of the few characters in the series aware of The Mask's true identity), or as part of some increasingly insane "science experiments" which if carried out would result in the death of thousands or even the end of mankind. He mostly pronounces Stanley Ipkiss' last name as "Ipp-kiss".
In the episode "Sister Mask", Pretorius did eventually gain the mask and as with Dorian Tyrell, he retained his own personality while wearing it (while the mask is said to release one's own inhibitions, those who have no inhibitions seem to retain full conscious control while wearing the Mask, such as the Joker in the DC crossover). Pretorius was also likely a parody of drug dealer/mob boss Eugene Rapaz from the original comics as both of them share the same face (though Rapaz wore small, rounded-lens dark glasses while Pretorius had round optic implants that looked similar as well) and is also named after Doctor Septimus Pretorius from Bride of Frankenstein.
He often says "Mental note" so he remembers to learn from his mistakes after he is foiled or needs to accomplish a task.
