Originally criminal mastermind and mad scientist Gerard Shugel, who was active during the 1940s, when Gerard's body was stricken with a terrible disease, he transferred his super-intelligent brain into the enhanced body of a rare white gorilla. Now the super-strong Ultra-Humanite, Gerard travels through time hoping to find the perfect era in which he can conquer the Earth.
One of Superman's oldest foes, his main claim to fame is his ability to transfer his own consciousness from one living body to another, but he also has invented a vast array of advanced weapons, vehicles, and other arcane technology with his genius level intellect.
A fiendish "mad scientist", Gerald he is paralyzed from the waist down and confined to a wheelchair. His "great goal" is the "domination of the Earth". Portrayed as nearly bald in two texts and as completely bald in two others, he is a "mental giant" and the "head of a vast ring of evil enterprises" whose "fiery eyes burn with terrible hatred and sinister intelligence." His real name is never given, but he has been known as the Ultra-Humanite (Ultra, for short) ever since "a scientific experiment resulted in [his] possessing the most agile and learned brain on Earth!"
