Maximus I.Q.

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.

His citadel contains various stolen items, such as a Starcruiser from "Best (Mis)Laid Plans" and a table (from when he was five) from "The Minion".

He commands a sizeable army consisting of both robot subjects and the ninja-like Blood Monks of Morbidia, and he is also one of the larger collectors of glass and rubber ducks. He loves ducks. And he is the "father" of The Betty Clones. Despite his hatred of Betty, he has occasionally teamed up with her: whether it's to foil the plans of his father, Max Sr., or, in "Takes One to Know One", to recover one of his stolen ducks from the villainness Pandora.

Among Maximus's many goals is to destroy Galactic Guardian Headquarters, as well as to locate and destroy Betty's home planet, both of which he has come close to doing on numerous occasions, before being ultimately repelled by Betty every time.
