Golden Age Origin

Marvo 1.2. Go+, the Superboy of the Year 2680, is a sci-fi hero of the future who fights foes such as the vest-wearing Antmen of Antar, the Antarenes. He is the son of one of the world's greatest scientists, and while only 15 years old, Marvo has inherited his father's intelligence. The "+" at the end of Marvo's name is a status symbol, usually awarded only to ten chosen adult men, which gives a person access to use the "Super-Hypnobioscope" that allows them to learn while they sleep. Aided by his friend Bud, Marvo has all types of adventures.

Superworld Comics was edited by Hugo Gernsbac, who created Ralph 124c 41 +. Marvo and Ralph are clearly intended to exist in roughly the same future reality, though Marvo's stories take place 20 years later.
