Multiplex

A nuclear physicist who was present during the same experimental reactor accident that created Firestorm, he gained the ability to split himself into numerous duplicate bodies — making him one of the Nuclear Man's earliest and most persistent foes.

Few villains feel as tailor-made for their nemesis as Multiplex, who burst onto the scene in Firestorm #2 in 1978 — a Bronze Age debut crafted by the sharp creative team of Gerry Conway and Al Milgrom. A DC antagonist built from the ground up to challenge one of the era's freshest heroes, Multiplex has haunted the pages of Firestorm and The Fury of Firestorm across an impressive span stretching all the way to 2025, proving his staying power in a crowded rogues' gallery. He's shared panels with heavy hitters like Green Lantern, The Flash, and Superman, and made his mark in Justice League of America as well — not bad for a villain who's been keeping Firestorm honest for nearly five decades. If you're tracing the Bronze Age roots of one of DC's most distinctive corners, Multiplex is exactly the kind of deep-cut character that rewards the curious collector.
