Ultra Boy

Superboy #98

Ultra Boy first appeared in Superboy #98 (1962), in which he was sent back in time to Superboy's home town of Smallville to prove himself worthy of joining the Legion by learning Superboy's secret identity. In his first adventure he only demonstrated his vision powers, known as "penetra-vision". It was implied he had malicious intentions in learning Superboy's secret identity. Later, in Adventure Comics #316, he explained that he could channel his ultra-energy to provide him other powers, though only one at a time. Later he was romantically linked for many years with fellow Legionnaire Phantom Girl.[3] He was considered one of the Legion's 'big 3' (along with Superboy and Mon-El) and served two terms as leader.[4][5]

The names of his parents are Crav and Mytra Nah. His girlfriend on Rimbor before he joined the Legion was An Ryd; she is later murdered by Pulsar Stargrave, who frames Ultra Boy for the crime.

Ultra Boy is a skilled actor; this, combined with his rough background on Rimbor and social standing, helps him infiltrate criminal groups when he appears to "go bad". This skill also makes him a valuable member of the Legion Espionage Squad; he is the only member without overt "spy" powers.

Between volumes 3 and 4 of the Legion of Super-Heroes, a five-year gap in the chronology occurred, during which the team disbanded. During this period Ultra Boy proposed to Phantom Girl, but she was apparently killed in an accident. Now known simply as Jo Nah, he had become a smuggler and an outlaw on his homeworld of Rimbor. He rejoined the Legion after assassins destroyed an entire apartment building trying to kill him.

A later storyline in the Volume 4 Legion of Super-Heroes (vol. 4) Annual #1 showed his acting skills. It was shown that for years Ultra Boy had played "dumber" than he was, to not give away any advantage to his foes. When the time sorceress Glorith began manipulating Legion history, she figured only the smarter legionnaires might notice her manipulations, and thus acted to neutralize ones like Brainiac 5. She never suspected Ultra Boy would figure out her plan, which involved provoking a battle between the Legion and Mordru at the zenith of his power, which would destroy or weaken both, allowing her to pick up the pieces. Realizing what this would mean, Ultra Boy first (in a fake diplomatic blunder) prevented the Legion from attacking Mordru, then, in disguise, visited Mordru and instead provoked him into attacking Glorith. This proved successful, leaving both Mordru and Glorith severely weakened. Years later Glorith finally figured out who was responsible and in revenge sent Phantom Girl into the past, leaving Ultra Boy believing her dead. Later still the Legion found themselves on the wrong side of the law and Ultra Boy adopted a new identity as Emerald Dragon.

During the "Five Year Gap" following the Magic Wars, Earth fell under the covert control of the Dominators, and withdrew from the United Planets. A few years later, the members of the Dominators' highly classified "Batch SW6" escaped captivity. Originally, Batch SW6 appeared to be a group of teenage Legionnaire clones, created from samples apparently taken just prior to Ferro Lad's death at the hands of the Sun-Eater. Later, they were revealed to be time-paradox duplicates, every bit as legitimate as their older counterparts. After Earth was destroyed in a disaster reminiscent of Krypton's destruction over a millennium earlier,[6] a few dozen surviving cities and their inhabitants reconstituted their world as New Earth. The SW6 Legionnaires—including their version of Ultra Boy—remained.

In the continuity that follows the 1994 Zero Hour: Crisis in Time! storyline, Ultra Boy's background is very similar to the original. He was a gang leader on Rimbor (running a gang called the Emerald Dragons, a reference to his Five Years Later identity), before being eaten by an Ultra Energy Beast and gaining his powers from eating the creature's flesh. He initially does not join the Legion but instead joins a rival group called the Workforce, and is briefly romantically linked to Spider Girl (Sussa Paka) before meeting and falling in love with Apparition, the post-Zero Hour incarnation of Phantom Girl, when the Workforce and Legion are stranded on Planet Hell, a prison complex located inside the sun. Eventually Ultra Boy leaves the Workforce and becomes a member of the Legion.

Ultra Boy and Apparition eventually marry and have a son named Cub, just before the Legion's reality was rebooted for the second time.

The Legion was rebooted again in 2005. Ultra Boy in this version seems much the same as his previous versions but does not have a romantic link with Phantom Girl; he is in a relationship with Shadow Lass. Trained by Karate Kid in a more responsible and tactical use of his superpowers, it's known by at least Triplicate Girl that on Rimbor, "he is charged for a crime he never committed", but refuses to say more on the question. He is later cleared of this crime (revealed to be Vehicular Homicide) when Legion business manager M'rissy discovered evidence that led to his innocence.[7] Kinder and mellower than his gruff exterior may express, he's the first one to sense Imra's displeasure and insecurities for being constantly neglected by her boyfriend, Lightning Lad. This however leads to a brief affair with the Titanian girl.

The events of the 2005–2006 "Infinite Crisis" storyline have apparently restored a close analogue of the Pre-Crisis on Infinite Earths Legion to continuity, as seen in "The Lightning Saga" story arc in Justice League of America and Justice Society of America, and in the "Superman and the Legion of Super-Heroes" story arc in Action Comics. Ultra Boy is included in their number.

In the "Watchmen" sequel "Doomsday Clock", Ultra Boy is among the Legion of Super-Heroes members that appear in the present after Doctor Manhattan undid the experiment that erased the Legion of Super-Heroes and the Justice Society of America.[8]

As a member of the Legion of Super-Heroes, Ultra Boy is provided a Legion Flight Ring, which allows him to fly and protects him from the vacuum of space and other dangerous environments. Although he has the equivalent innate abilities, the ring allows him to forgo them and leave another of his powers available for use.
