Gim Allon

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. After realizing that Gim Allon's surname Allon was of Israeli origin, writer Paul Levitz identified the character as Jewish in 1980.
