Gim Allon, also known as Colossal Boy, Leviathan, and Micro Lad, is a superhero appearing in books published by DC Comics, primarily as a member of the Legion of Super-Heroes in the 30th and 31st centuries. Created by writer Jerry Siegel and artist Jim Mooney, the character first appeared in Action Comics #267 (August 1960).

He has gone by a variety of superhero names over the past several decades, although originally (and most commonly) Colossal Boy. His name's similarity to the Israeli surname Allon led writer Paul Levitz to identify the character as Jewish in 1980.

In the 1990s, the entirety of the Legion of Super-Heroes were changed in what is referred to as a "reboot" of those characters' continuity, including Allon. Later on, these superheroes were again rebooted in what has been referred to as the "Threeboot".

Fictional character biography

Original continuity

Gim Allon as Colossal Boy, in his Silver Age costume; art by Curt Swan and George Klein.

Gim Allon was mutated by a radioactive meteorite, gaining the superhuman ability to increase his size. With his parents' blessing, he joined the Legion of Super-Heroes under the codename Colossal Boy. 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 Allon. 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, Colossal Boy joined the Science Police as Earth fell under the control of the Dominators and withdrew from the United Planets, during which "Batch SW6", temporal clones of the Legionnaires, escaped captivity. This universe was erased from continuity after Zero Hour.

1994 reboot

In 1994, following the events of the Zero Hour: Crisis in Time! 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. He was still human, as Mars had been colonized by humans in this continuity. 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 Empress' Emerald Eye of Ekron, 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. He also passed along his ability to grow to tremendous size to Violet.

2004 reboot

Main article: Legion of Super-Heroes (2004 team)

In the 2004 relaunch, Gim Allon is a member of a 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 cleanup operations.

An Imskian villain used the name Micro Lad in the original continuity.

Post-Infinite Crisis

The events of the Infinite Crisis miniseries 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).

In the "Watchmen" sequel "Doomsday Clock", Colossal 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.

The New Golden Age

In the pages of "The New Golden Age", Colossal Boy is among the Legion of Super-Heroes members that arrive in the present and confront the Justice Society of America over their decision to add Legionnaire (a younger version of Mordru wanting to avoid the path of evil) to their ranks.

Powers and abilities

As Colossal Boy or Leviathan, Gim Allon can increase his size into many times normal height, with strength proportionate in mass. He additionally possesses expertise in law enforcement. In the 2004 reboot of the Legion of Super-Heroes, he is giant-sized normally and can shrink down to six feet tall.

Equipment

As a member of the Legion of Super-Heroes, Gim Allon is provided a Legion Flight Ring, which allows him to fly and survive in the vacuum of space and other dangerous environments. Brainiac 5 modified his ring so it would enlarge with him, thus supporting the additional mass.
