Challengers of the Unknown [Ace Morgan; Professor Haley; Red Ryan; Rocky Davis]; June Robbins
After hearing a television report about a burglar with the ability to walk through walls, the Challengers begin to patrol the city with honorary member June Robbins coming along for the ride. They arrive too late to stop another robbery, but they pursue the thief to his island hideout. The hideout of the burglar, Anton Zammer, is the abandoned laboratory of the late Prof. Macon, who left behind a number of inventions Zammer now intends to use for his own gain. He starts with a shrink ray which allows him to capture and cage the Challs. Fortunately, their honorary member doesn't get shrunk, and has the smarts to save the day.
