For the young lad who would one day become Master Man, however, there seemed no such threat to his personal heallth. In order to cure himself of ailments as a toddler, a mystery physician had him ingest the Vitacap, which permenantly endowed him with superhuman abilities. Comparable to another powerhouse red head in Al Pratt aka the Atom of Earth-Two, Master Man possessed superstrength, endurance, and speed. A mighty mite of equal parts intellect and physique like Al and Ray Palmer aka the Atom of Earth-One, all equally colorfully clad.
Master Man quickly detached himself from society as he moved to a mountaintop headquarters. Coming back down to Earth-S only to clean up its human filth, his career was rather shortlived. As such, he never came to associated with fellow costumed crimefighters of his world, either the Crime Crusaders Club or the Marvel Family.
