Ultra Boy

The Origin of Ultra Boy by Siegel, Swan & Klein

Ultra Boy Real Name: Jo-Nah

A member of the Legion of Super-Heroes, Ultra Boy from the planet Rimbor has comparable powers to Superboy and Mon-El, though he can only use one super ability at a time. His Penetra-Vision is more powerful than theirs as Ultra Boy can see through even Lead but not the super-dense material known as Inertron.

As an adult, Jo married long-time girlfriend, Phantom Woman (Tinya Wazzo).
