History: Very little is known about the back ground of Captain Ultra. He was first glimpsed in the New York area when he answered a newspaper advertisement placed by the Wizard to recruit a new fourth member for the Frightful Four. Although the Wizard deemed Ultra's superhuman power a worthy addition to the team, he soon rejected the applicant for fainting in the presence of a lit match. Captain Ultra was next glimpsed at the mass meeting for "super heroes" at the Richmond Riding Academy on Long Island prompted by an unauthorized television programming revealing the existence of the Defenders. Among the twenty costumed crimefighters who investigated the spurious open invitation, Ultra accompanied a small band of them into New York City to stop a crime spree. Like the rest of the ersatz Defenders, Captain Ultra became disenchanted with the team and never petitioned the core members of the Defenders for acceptance into their ranks. Captain Ultra was seen in Chicago, where in his civilian identity he relocated, when he stumbled into the thunder god Thor during the Asgardian's brief residency there. Captain Ultra's current activities are unknown.

Strength Level: Captain Ultra possesses superhuman strength enabling him to lift (press) approximately 9 tons under optimal conditions.

Known Superhuman Powers: Besides superhuman strength, Captain Ultra possesses the ability to fly (presumably this is a natural ability and not a properly of his costume) and the ability to see through solid objects (also presumably natural). Ultra can fly at speeds up to 60 miles per hour, the maximum rate of speed at which he can still breathe. He can see through substances up to 18 inches in thickness, at a maximum distance of 20 feet.

Limitations: Captain Ultra cannot tolerate fire, even the minutest flame. Whether this is a physical vulnerability or a psychological aberration is not known.
