Superman meets a super powered man who claims he is also a survivor from Krypton. The man proves to be Superman’s equal and also is invulnerable to Kryptonite. He tells Superman about a substance on another planet that will also give Superman immunity to Kryptonite. When the Man of Steel leaves, the man reveals himself as a criminal given temporary powers from a meteorite. The crook and his partners try to rob a government depot with Superman on another planet. However, Superman has seen through the story and prevents the theft. The crook’s powers wear off, allowing Superman to apprehend the gang.
