Fictional character biography

Legion of Super-Heroes

Star Boy is a member of the Legion of Super-Heroes, a group of young heroes living a millennium in the future. He was born to astronomer parents on an observation satellite orbiting the planet Xanthu with the ability to temporarily increase the mass of an object, up to the mass of a star. Although he temporarily acquires Kryptonian-level powers similar to those of Superboy when he was caught in the tail of a comet, these eventually fade (leaving only his original density-increasing power). Early in his Legion career, he travels to the 20th century to meet Superboy. While he is there, to make Superboy jealous Lana Lang threatens to expose his identity (a secret on Xanthu) if he refuses to pretend to be her boyfriend. However, the Boy of Steel overhears her and her plan fails.
