The self-proclaimed Supreme Evil Overlord of the Galaxy, Maximus I.Q. (voiced by Colin Fox) has only one driving ambition — to rule the galaxy. He serves as the main antagonist in the series. He presents enough of a danger that he is Betty's most annoying and frequent nemesis, with a cat-like appearance and a somewhat regal bearing (even if he's the only one who believes so). Like any other cat, however, he hates getting wet, to the point where it is enough to distract him from his schemes. He is also ill-tempered, self-important, overbearing, scheming, two-faced, abusive, selfish, and thievish.
