Commander Steel (also known as Captain Steel, Citizen Steel and Sergeant Steel) is the name of three superheroes appearing in comics by the American publisher DC Comics, all members of the same family. The first Steel appeared in Steel, The Indestructible Man #1 (1978), and was created by Gerry Conway and Don Heck. His stories were set in World War II. The two later characters called Steel are his grandsons. Nate Heywood / Steel, his grandfather Henry Heywood / Commander Steel, and Nate's father Hank Heywood all appear in Legends of Tomorrow, portrayed by Nick Zano, Matthew MacCaull, and Thomas F. Wilson respectively. Publishing history Steel first appeared in a series set in 1939, Steel: The Indestructible Man, written by Captain America writer Gerry Conway. The series was canceled after five issues, and Steel later made a guest-appearance in Justice League of America. Steel was also a member of the World War II era All-Star Squadron team. He made a prominent appearance many years later in four issues of the Eclipso ongoing series, where he was killed. After this, he appeared in issue #2 of the 2010 series, DC Universe: Legacies, which chronicled the superheroes of the 1940s. The character served as an homage to the Marvel Comics character, Captain America. "Steel was intended to be a tip of the hat to the original Captain America. My favorite Cap stories, when I was growing up, were the ones Stan and Jack set in World War II, so I was just trying to recapture that feeling." Starting in 1984, the second Steel appeared as one of the lead characters in Justice League of America, until its cancellation during the Legends crossover in 1987. He made a single appearance several years later in issue #38 of Justice League America, a continuation of Justice League International, where he was killed. In 2006, he played a leading posthumous role in a single story arc of JLA Classified, which chronicled a previously unrevealed adventure of the Detroit-era JLA. In 2010, he played a major role in the two-issue Justice League of America vol. 2 tie-in to Blackest Night, where he was temporarily resurrected. The third Steel made his debut in the 2007 relaunch of Justice Society of America, where he appeared for several years until the team was split into two separate groups by writers Bill Willingham and Lilah Sturges, where he appeared as one
