Leviathan

Gim Allon is a Legionnaire with the power to grow to enormous size, serving alongside fellow heroes in the Legion of Super-Heroes in the 30th century. His colossal stature makes him a formidable frontline defender for the team.

Emerging from the early 1990s DC universe courtesy of Steve Englehart and Neil Vokes, Leviathan made their debut in Congorilla #4 in 1993 — an intriguing entry point for a character who would go on to share pages with the likes of Darkstar, Triad, and Salu Digby across titles like Legion of Super-Heroes and Legionnaires. A Copper/Modern Age creation with a footprint spanning some of DC's most expansive corners, Leviathan is one of those quietly compelling figures whose brief but varied appearances reward the curious reader willing to dig into the era's rich, ambitious storytelling.
