Comments:
Cosmic Boy’s power is incorrectly shown radiating from his eyes, rather than his hands, in this story.

Saturn Girl is incorrectly depicted as a brunette in this story, and her costume is colored purple and white, not red and white; moreover, on the cover, she is erroneously shown casting lightning bolts from her eyes.

The element "Sigellian" introduced in this story is named after the story’s writer, Jerry Siegel.

Synopsis:
Superboy is surprised to discover that Cosmic Boy, Saturn Girl and Lightning Lad have travelled back to the 20th century for no other apparent reason than to make him look bad by beating him to the punch with each and every single super-feat he tries. Eventually the whole town of Smallville turns against him, and Superboy exiles himself into space.

There, he comes across a crowd of super-beings on their way through space. Following them, the Boy of Steel finds himself on a new world known as the Superboy Planet, but is immediately thrown into a Kryptonite jail cell by the Legionnaires, who eventually explain the circumstances of his confinement. They tell him that they had come to the past and enlisted the super-heroes of several worlds to build a planet to honor Superboy. While there, however, the Legion used their Futurescope to check Superboy’s future and saw him deliberately destroying an airstrip, a ship, and a factory. Afraid that he would become a super-outlaw, Saturn Girl used her powers to force the citizens of Smallville to ostracize him and trick him into being captured.

Eventually, an explosion frees Superboy, and releases a deadly element from which he rescues the Legionnaires. When Saturn Girl picks up a radio message from the President of the United States which frees him from his "security oath," Superboy reveals that the Futurescope had accidentally turned in on the present, and had shown him destroying poisonous gas for the government, a mission cloaked by national security.

Exonerated, Superboy is honored by the super-heroes.
