A Venusian man who would become known as Sub-Zero was a part of an expedition that was launched to establish first contact with Earth. Before the spaceship could enter Earth's atmosphere, it passed through a comet. Everything inside was frozen. One crewman managed to survive, but the exposure turned him into a living ice man that froze everything he touched. He managed to steer the ship towards earth, crash-landing it near Salt Lake City. He painfully escaped the craft while covered in ice and then made his way to the nearest building.

The building happened to be full of scientists experimenting with "gamma radiation." They used the gamma rays to return the Venusian to his original humanoid form, though his ability to freeze objects remained. Blending in with America's civilian population in the city of Centro, he became a detective and used his superhuman abilities to fight crime.

He was originally known as Sub-Zero Man, but he became simply Sub-Zero shortly thereafter. He teamed up with fellow heroes Blue Bolt and Twister and also had a sidekick by the name of Freezum. His enemies included the likes of the Green Turtle and Professor X. He could shoot ice from his hands to stop wounds from bleeding, to create a protective shell to prevent injury and could cause freezing in a specific, localized area, once freezing water underneath a submerged car to lift it out of the water. He could create cyclones by hurling blasts of cold air.
