Fictional character biography

Original continuity

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.^[1] 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, Gim joined the

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 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. He also passed along his ability to grow to tremendous size to Violet.

2004 reboot

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.
