The Sizzler was an artificial life-form created by Professor Snakelocks from photo-molecular energy siphoned from the Aurora Borealis. She once turned the Metal Men into humans and transformed Dr. Will Magnus into a robot. Like Platinum, Sizzler seemed to be in love with Doctor Magnus (getting jealous when he showed affection to Platinum and vice-versa). She appeared to have exploded when Doc Magnus tried to add a responsometer, causing metal shards to plunge into his heart. Whether Sizzler really exploded or not (considering how powerful and unpredictable she really was, something that Snakelocks tried to warned Doc Magnus about) is currently unknown.

- This version of Sizzler (Earth-One), including all history and corresponding appearances, was erased from existence following the collapse of the original Multiverse in the 1985–86 Crisis on Infinite Earths limited series. Even though versions of the character may have since appeared, this information does not apply to those versions.
