Leviathan

Bursting onto the scene in 1996's Showcase '96 #8, courtesy of creators Tom McCraw and Roberto Flores, Leviathan is a DC character rooted in the Copper/Modern Age who carved out a niche in the far-future corners of the DC Universe. With appearances across titles like Legion of Super-Heroes: The Beginning of Tomorrow and The Legion, this character keeps remarkable company — sharing pages with Legion luminaries like Saturn Girl, Chameleon, and Gim Allon. A relatively rare find in the catalog with just three recorded appearances, Leviathan carries the allure of a deep-cut discovery for fans who love to dig into the rich, sprawling mythology of DC's 30th-century adventures.
