​Doctor Blizzard (secret identity Keith Nolan, often mistakenly referred to as Professor Snowflake or, as he was once derogatorily called, Mr. McFlurry) was an unpopular superhero and the lesser-known fourth member of the Super Squad in Supermen: The Musical. Later, it was discovered that he was actually the Mystery Hero Slayer, and the primary antagonist of the show.
