Place of Birth



A freak accident irradiated Ultra Boy with a hyperkinetic energy bouncing inside of him that could be used for various effects.

He comes from the rough and tumble planet Rimbor, where he can never return to, or he'll be executed for a crime that, according to Triplicate Girl, he never committed.

Ultra Boy has dated Light Lass and Triplicate Girl earlier. He's currently dating Shadow Lass. Despite his ability to fly he shows a strong love of automotive transport; getting a good deal of pleasure from driving a (presumably incredibly antique) Car.

When Ultra Boy's powers began to go out of control, Shadow Lass forced him to seek help from Karate Kid.In a battle later in the same arc however, while Karate Kid and Ultra Boy are battling numerous foes Karate Kid questions why Ultra Boy isn’t using the full extent of his powers. Ultra Boy responds that he is just following the Kid’s teaching and Karate Kid; as they are being overwhelmed veritably orders Ultra Boy to stop trying to control himself and cut loose. Implying that his habit of rapidly switching between powers and not worrying was the key to managing them.

Powers and Abilities



Ultra-Energy Empowerment: Ultra Boy can utilize the ultra-energy in his body in a variety of ways, but only one at a time. He can utilize it for any of the following:

  • Ultra-Speed: When using this power he can move, he can think and run faster than the eye can follow. An extension of this speed is his ability to fly.
  • Ultra-Invulnerability: When using this power, he is impervious to harm by nuclear forces. If propelled at sufficient force, by either his flight ring or a super-toss, Ultra Boy can use his ultra-hard body like a human missile.
  • Ultra-Vision: Ultra Boy's penetra-vision makes him able to see through solid matter, although he appears to be unable to see through lead. As part of his same ultra-vision power, Ultra Boy can use telescopic vision, in combination with penetra-vision if desired. He also has microscopic-vision and is able to analyze fingerprints.
  • Flash Vision:Ultra Boy's flash vision works like heat vision but is stronger.
Ultra-Aura of Protection: Ultra Boy's ultra-energy radiates an aura, which protects his clothing from being torn when invulnerable, and from burning-up from the friction when traveling at super-speed.

Strength level

One Power at A Time: As mentioned above, one serious limitation to his ultra-powers is that he can only use one at a time. This means that if he wants to fly through space at super-speed he must wear a spacesuit to survive in the cold vacuum. When using his power for super-strength he is not invulnerable and can therefore get tired, feel muscular pain or even pull a muscle.

While he can switch his ultra-energy from one power to another almost instantaneously, Ultra Boy can be caught off-guard and unawares.

Penetra-Vision Limitation: Ultra Boy's penetra-vision appears unable to penetrate lead.
