A mutant with the ability to subconsciously manipulate thermodynamics to create fields of intense cold, Hypothermic is surprisingly powerful but also somewhat fragile.

Hypothermic worked solo briefly under the code name Iceblue, but got in over his head and was almost killed or badly maimed fighting a gang of street thugs. Luckily he was saved by Hype, the Hypersonic Man, another mutant crime fighter. The two worked well together and teamed up on and off for many years; Hypothermic dropped the Iceblue name in favor of his current moniker to accentuate the heroic duo thing.

At Hype's urging and sponsorship, Hypothermic joined the Millennial Men supergroup and quickly proved to be a mainstay for the team. Over the ensuing years Hypothermic has fought more supervillains than he can recall, helped fend off several alien invasions and two dimensional incursions, stood firm in the face of supernatural horrors from beyond, disrupted seemingly endless villainous schemes, and has done his part to save the world at least a dozen times...all while somehow managing to retain his rather corny sense of humor.

Despite his long experience, incredible power, and history of success, Hypothermic still enjoys patrolling the streets for everyday crime like a neophyte or low powered hero, and is famous for inviting old friends to go out and "patrol" with him to catch up on old times. The surrealism of the likes of Hypothermic and his old bud Hype, or other world-class superheroes like Microwave, or Proto, or Tennebrae and so on taking down street thugs seems to be entirely lost on him.
