Jo Nah

DC

Ultra Boy, whose real name is Jo Nah, is a superhero from the 30th century in the DC Comics universe. He is a prominent member of the Legion of Super-Heroes.

Hailing from Rimbor, Jo Nah gained his powers after being swallowed by an ultra-energy beast as a child. This incident granted him a unique ability: to possess any one super-power at a time. He can switch between super-strength, flight, invulnerability, energy blasts, super-speed, super-vision, and super-intellect, but can only use one at any given moment.

Ultra Boy is known for his strategic thinking and leadership skills within the Legion. His weakness, the inability to utilize more than one power at once, forces him to make tactical choices in combat. His romantic relationship with fellow Legionnaire Phantom Girl is a significant aspect of his character.

Over the years, Ultra Boy has undergone various reboots and reinterpretations along with the rest of the Legion, but his core powers and personality have largely remained consistent.
