Ultra Boy is a member of the Legion of Super-Heroes.

Jo Nah first appeared as a competitor at the Intergalactic Games on Olympic 12. When the Fatal Five attacked the games, Jo, along with Kem of Bismoll, helped the Legion defeat them, calling out the names of four of his various ultra-powers as he activated them ("Super strength!" "Invulnerability!" "Super-speed!" "Freezing breath!"). Phantom Girl complimented his skills and thought to herself that he was cute. Jo Nah appeared later as a full Legionnaire and offered his services to help the Legion stop the Sun-Eater.
