Ultra-Humanite is a villain from the DC Universe.
Originally a criminal scientist active during the 1940s, the Ultra-Humanite escaped death by transplanting his brain into other bodies; including film star Dolores Winders, a giant ant, and a genetically enhanced albino ape.
The Ultra-Humanite is the first supervillain faced by Superman, and among the first supervillains of the Golden Age of Comics. He was designed to be the polar opposite of Superman; while Superman is a hero with superhuman strength, Ultra-Humanite is a criminal mastermind who has a crippled body but a highly advanced intellect. The Ultra-Humanite served as Superman's nemesis until Lex Luthor was introduced in the comics. The origins of the super-criminal known as the Ultra-Humanite are shrouded in mystery. Even he claims not to remember his true name or appearance and attributes his vast intellect and mental prowess to scientific experiments of an unknown nature.
Ultra deals Superman electricity sufficient "to kill 500 men", and Superman lapses into unconsciousness. With Superman now helpless, Reynolds and the Ultra-Humanite attempt to kill him with a buzz saw, but Superman's invulnerable skin obliterated the saw into tiny pieces. Reynolds is killed by one of the flying pieces. Ultra's henchmen set fire to the cabine and leave Superman behind to perish. The Ultra-Humanite is carried outside to a waiting aircraft. Superman regains consciousness and deliberately crashes into the plane. The Man of Steel is unable to find the Ultra-Humanite's body
A mysterios epidemic sweeps through the city, killing hundreds. A young scientist, Professor Henry Travers, concocts an antidote. Ultra kidnaps Travers, but he is rescued by Superman. Ultra's henchmen fire an unknown ray and knock out Superman. Ultra tries hypnotizing him by placing a helmet on his head, but Superman fakes being controlled, and when he is taken to spread the plague with a henchman, he destroys the "fantastic airship of Ultra's creation" that was spreading its "cargo of Purple Death". Superman returns to Ultra's stonghold where the villain tries to blast him, but Superman places the Ultra-Humanite in front of the gun, killing him.
