Summoned to a lab, the Challs observe a monkey with super abilities. It was given a pill derived from a meteorite, then boosted into space. Rocky is chosen to take the pill and rockets into space unaware the monkey has lapsed into a coma. The rocket crashes and Rocky emerges with super powers, including freeze rays, super strength, and invisibility, but he becomes irrational. A crook takes Rocky in hoping to use him to rob banks. Rocky's decency wins out and when the Challengers and June appear Rocky shocks the crooks. Grazed by a bullet Rocky recovers his memory and his powers wear off.
