'''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 Colossal Boy is the first and most common. His name's similarity to the Israeli surname [[Allon (surname)|Allon]] led writer [[Paul Levitz]] to identify the character as [[Jew|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 is a human who gains the ability to increase his size after being exposed to a radioactive [[meteorite]]. With his parents' blessing, he joins the Legion of Super-Heroes as Colossal Boy.<ref>{{cite book |editor1-last=Cadigan |editor1-first=Glen |title=The Best of the Legion Outpost |date=2004 |publisher=TwoMorrows Publishing |isbn=9781893905368 |page=8 |url=https://books.google.com/books?id=5iFklF_oCMgC&dq=%22colossal+boy%22&pg=PA8 |access-date=29 March 2020}}</ref> He has an unreciprocated crush on fellow Legionnaire [[Salu Digby|Shrinking Violet]], and the two eventually marry. For a time, Colossal Boy's mother Marte is President of Earth.

During the [[Legion of Super-Heroes#"Five Years Later"|"Five Year Gap"]] following the Magic Wars, Colossal Boy joins the [[Science Police]] as Earth falls under the control of the [[Dominators (DC Comics)|Dominators]] and withdraws from the [[United Planets]]. Amidst this, "Batch SW6", temporal clones of the Legionnaires, escape the Dominators' captivity.<ref>''Legion of Super-Heroes'' (vol. 4) #38 (late December 1992)</ref>

===1994 reboot===
{{main|Legion of Super-Heroes (1994 team)}}
Following ''[[Zero Hour: Crisis in Time!]]'', which rebooted the Legion's continuity, Gim Allon is known as Leviathan and originates from a Martian colony. He is the Legion's first leader, but resigns after one mission in favor of [[Cosmic Boy]] and becomes deputy leader. Allon is later killed in battle with Doctor Regulus, with Shrinking Violet gaining his powers.

===2004 reboot===
In the "[[Threeboot]]", Gim Allon's species is created by [[Brainiac (character)|Bizarro Brainiac]]. They are normally giant-sized and can shrink down to human size.

===Post-''Infinite Crisis''===
The events of ''[[Infinite Crisis]]'' restore a close analogue of the pre-''[[Crisis on Infinite Earths|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 (comics)|Superman and the Legion of Super-Heroes]]" story arc in ''[[Action Comics]]''. Colossal Boy is included in their number, along with his wife [[Yera Allon]].

In ''[[Doomsday Clock (comics)|Doomsday Clock]]'', Colossal Boy is erased from existence when [[Doctor Manhattan]] alters the timeline. However, he is restored when [[Superman]] convinces Manhattan to undo his actions.<ref>''Doomsday Clock'' #12 (December 2019). DC Comics.</ref>

===The New Golden Age===
In ''[[The New Golden Age]]'', Colossal Boy is among the Legionnaires who arrive in the present and confront the Justice Society over their decision to recruit Legionnaire, a young, heroic incarnation of [[Mordru]].<ref>''Justice Society of America'' (vol. 4) #10. DC Comics.</ref>

==Powers and abilities==
As Colossal Boy or Leviathan, Gim Allon can increase his size into many times normal height, with strength proportionate in [[mass]].<ref>''Who's Who in the Legion of Super-Heroes'' #1 (April 1988)</ref> 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.<ref>''Legion of Super-Heroes'' (vol. 8) #8 (October 2020)</ref>

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.
