Multiplex is the archenemy of Firestorm
Even before he became a supervillain, Danton Black was a cruel and arrogant being. The assistant of Professor Martin Stein, Black was fired when Stein caught him stealing lab materials. But Black twisted everything and said that Stein was the one who stole HIS work, placing a legal junction on Stein's dream project of a nuclear reactor. But Stein wouldn't let his corrupt ex-assistant to ruin his chance, and activated the reactor, which was then blown up by terrorist Ernie Earhart, and fused Stein with high school senior Ronnie Raymond, thus creating the superhero Firestorm. But Black was also caught in the explosion, and gained the power to create duplicates of himself, thus turning into Firestorm's archenemy Multiplex. Multiplex is the greatest thorn in the Nuclear Man's side, and will not rest until he's snuffed out Firestorm's flaming head
