Gim Allon, also known as Leviathan, and Micro Lad, is a fictional character in the 30th and 31st centuries of the DC Comics universe who has gone by a variety of superhero names over the past several decades, although originally (and most commonly) Colossal Boy. He is a member of the Legion of Super-Heroes. He first appeared in Action Comics #267 (August 1960). In the 1990s, the entirety of the Legion of Super-Heroes were changed in what was referred to as a "reboot" of those characters continuity, including Allon. Later on, these superheroes were again restarted in what has been referred to as the "threeboot" of the Legion of Super-Heroes. This last version is currently being published by DC Comics.
Fictional character biography
Gim Allon was mutated by a radioactive meteorite, gaining the superhuman ability to increase his size. His superhero codename became Colossal Boy. With his parents' blessing, he joined the Legion of Super-Heroes, becoming a member in good standing. He had an unreciprocated crush on fellow Legionnaire Shrinking Violet; this crush was only returned when Violet was replaced by a shapeshifting impostor, a Durlan named Yera. The two were married; when the deception was exposed, he discovered that he was still in love with Yera, and they remained married. For a time, Colossal Boy's mother Marte Allon was the President of Earth.
During the "Five Year Gap" following the Magic Wars, Gim joined the Science Police and ultimately never returned to the Legion. 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 the destruction of Krypton over a millennium earlier, a few dozen surviving cities and their inhabitants reconstituted their world as New Earth. The SW6 Legionnaires remained, and their version of Colossal Boy assumed the code name Leviathan.
In 1994, following the events of the Zero Hour crossover, the original continuity of the Legion ended and their story was restarted from the beginning. In this continuity, Gim Allon was known as Leviathan and was from Mars instead of Earth. Like his previous counterpart, he was a Science Police officer who was given his powers after being grazed by a meteorite.
He was the first official leader of the team, but he resigned after one mission, following the death of the first Kid Quantum and realizing that Cosmic Boy was more suited to the role. Cosmic Boy persuaded him to retain some leadership as deputy.
Allon then became ensconced in a love triangle. While he nursed a crush on Kinetix, Shrinking Violet nursed a crush on him. This ended in tragedy when the Emerald Eye, on orders from Violet to give each member of the team their heart's desire, caused him to die in battle with Doctor Regulus, fulfilling his wish to have a heroic death.
In the 2004 relaunch, Gim Allon is a member of race of giants created by Bizarro Brainiac 200 years prior to the start of the 31st century. Allon considers his superpower to be the ability to shrink to six feet tall and prefers the code name Micro Lad. Still, all Legionnaires, as well as the public in general, know him as Colossal Boy. He often affects a bemused manner with his comrades, enjoying his time spent with "little people." Gim is often both the first and last Legionnaire in a fight, as his size grants him first strike ability as well as serving useful in the cleanup operations which inevitably follow.
(An Imskian villain used the name Micro Lad in the original continuity.)
The events of the Infinite Crisis miniseries have apparently restored a close analogue of the Pre-Crisis 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. Colossal Boy is included in their number, along with his wife Yera (who has taken the name Chameleon Girl).
Powers and abilities
As Colossal Boy or Leviathan, Gim Allon could increase his size to many times the height of a human, with proportionate increases in strength and mass. In the 2004 version of Legion of Super-Heroes, the character insists that his powers involve shrinking instead of growing, although the effect upon opponents appears to be the same.
In other media
Colossal Boy made a cameo in the Justice League Unlimited episode "Far From Home".
Colossal Boy appears in three episodes of the first season of the animated TV series Legion of Super Heroes. In "Timber Wolf," he is only seen on a monitor. In "Lightning Storm", he helps the Legion stop a squid-like alien in space. He appears in "Chain of Command" for a mission. He became a semi-regular character in the second season. He was voiced by Adam Wylie.
