What's His Problem? A pharmaceutical chemist gifted with a super-speed formula by the alien Grandmaster, Sanders joined the Grandmaster's Squadron Sinister as the super-villainous Whizzer. A vainglorious power-tripper at heart, the Whizzer enjoyed outracing the law and continued his criminal career after leaving the Grandmaster's service. Desirous of a more uniquely formidable costumed persona, Sanders later concocted an improved version of the speed formula and continued his criminal career as the super-swift Speed Demon.
