During World War II, government scientists developed a "Super-Soldier formula" based on experiments with cellular samples from an alien corpse. They administer the formula, as well as solar radiation, to a young man named Clark Kent. The mixture of the formula and the radiation give Kent incredible powers and abilities, including super-strength, heat vision, and flight. Reporter Jimmy Olsen, who sneaks into the Super-Soldier program laboratory, makes a deal with the government: he will not tell the world about the project if the government makes him the "official press flak" for the Super-Soldier.
Super-Soldier gains a sidekick for a short time named American Girl and becomes a member of the All-Star Winners Squadron. Clark Kent was romantically interested in Lois Lane and dismayed when she marries Lex Luthor, a cold-hearted billionaire. In Super-Soldier: Man of War #1, Super-Soldier, aided by Sgt. Rock and his Howling Commandos, Jimmy Olsen, and Agent Peggy, fight Major Zemo, a member of HYDRA, a Nazi organization, who is secretly working for Lex Luthor, the behind-the-scenes leader of HYDRA and friend of Adolf Hitler himself.
By March 1942, Super-Soldier "had the war all but won nearly single-handedly until the rise of Ultra-Metallo", in the words of Jimmy Olsen. Ultra-Metallo is a massive robot later revealed to be sent by Lex Luthor. Super-Soldier sacrifices himself to take down Ultra-Metallo, the two of them sinking beneath the icy waters, with Jimmy Olsen as one of the few witnesses. Instead of reporting to the world that Super-Soldier was dead, Jimmy Olsen instead reports that Super-Soldier had retired, after declaring the war won by America.
Fifty years after Super-Soldier's battle against Ultra-Metallo, the JLA discover the frozen body of Super-Soldier in JLA #4. After thawing the great hero out, he joins the team and begins working at the Daily Planet as Clark Kent. In Super-Soldier #1, he discovers that Lex Luthor is still alive and well, having injected himself with Green K, a part of the meteorite that landed next to the space rocket so many years before, to greatly lengthen his lifespan, though it turns his skin a hideous shade of green. Lex Luthor, with HYDRA at his side, first kidnapps an aged Jimmy Olsen to give Super-Soldier a message. Jimmy returns, badly beaten, informing Super-Soldier that HYDRA is in Washington, D.C. Super-Soldier heads there, where he discovers that Lex Luthor and HYDRA have revived Ultra-Metallo, who is now powered by Green K itself, which weakens Super-Soldier.
Super-Soldier, discovering that lead protects him from the harmful Green K, used an enormous lead pipe to take down Ultra-Metallo before it can detonate a "K-Bomb" at the White House. Super-Soldier finally exposes Lex Luthor, and Luthor was incarcerated. After taking down Lex Luthor, he fought against the monstrous alien known as Doomnaut. At the end of Super-Soldier #1, Super-Soldier reveals that he is becoming weaker due to the fallout of the K-Bombs that were inside Ultra-Metallo. In the Amalgam Comic Lobo the Duck #1, an alternate future is shown where Super-Soldier, among many other heroes, is dead. As the Amalgam Universe is separated in Marvel versus DC #4, Super-Soldier's current status is unknown.
Powers and abilities
Initially, the combination of the Super-Soldier formula and exposure to solar energy gives a Super-Soldier a wide array of powers including super-strength, flight, invulnerability, and heat and x-ray vision.
