Superboy #52

In "The Power-Boy from Earth," Superboy meets Power-Boy, a survivor from Earth’s distant past awakened on the planet Juno. Though forged in the ancient world of 10,000 years ago, Power-Boy’s strength is matched only by a single, fatal flaw—one that keeps him forever out of reach from his new ally. Ma Vorne and Pa Vorne, the only known figures from the story’s Earth, remain part of the mystery behind this forgotten hero’s legacy.
