Synopsis:
Multi-Man has escaped prison again and learned how to alter his body into two new forms: one possessing anti-gravity abilities, the other a form of pure energy. The Challs trail the crook while Prof stays behind to work on an antidote for the formula.

Ace and Rocky are captured by Multi-Man’s men and tied up. The villain reveals that he plans to find a way to combine the three forms and gain all the powers at the same time. Then he plans to blackmail the world into surrender.

June and Red free their captive comrades and follow their foe, but they arrive too late to stop him from combining the three forms into one. Prof arrives in a helicopter and battles the airborne foe. When Prof uses the antidote on him, Multi-Man falls to the Earth. He survives in his super-intelligent form, but now has amnesia, forgetting everything including his own identity.
