DC Comics
In DC Comics, Sarge was eventually put in charge of the United States' governmental agencies involved with "superhuman" activities for many years. He was apparently the head of a small agency known as the CBI (Central Bureau of Intelligence), which also included King Faraday, and Faraday's two well known agents Richard Dragon and Ben Turner. He was eventually depicted as a Federal Cabinet Secretary of Metahuman Affairs (giving him control of agencies such as the Suicide Squad).
Around this time Sarge is sent in to investigate the country of Bialya. The entire place had re-opened, now a trendy vacation spot, after months of a media blackout. Sarge encounters Captain Atom, Major Force and the second Rocket Red as various attacks rattle the country.
Around this time, the manipulative, caterpillar-shaped alien criminal Mr. Mind is handed over to Steel's custody. Mr. Mind takes control of Steel, hiding inside his artificial hand in order to escape the detection of superhumans. Controlling Steel, Mind causes the nuclear devastation of the midwest American city of Fairfield. Though superhumans contained the bombs to the literal limits of the town, many thousands died.
Later, Lex Luthor would be elected as President. Luthor appoints Amanda Waller as his successor until Luthor was re-exposed as a criminal in the events of Superman/Batman: Public Enemies.
Steel has since resumed his old Cabinet posting as a member of the Horne Administration. He is currently in charge of Nemesis and Diana Prince as part of the Department of Metahuman Affairs. During his time at that post the villain Circe kidnapped Steel, tied him up, duct taped his mouth shut, locked him in a closet, and had him replaced with her shape-shifting henchman Everyman. Using Steel's pull at the agency, Circe and Everyman helped bring about the events of Amazons Attack.
In the end, Steel is freed, but he's left overtly suspicious over Wonder Woman's motives, questioning she may still serve the Amazons cause, to him perceived as harmful and dangerous. He correctly guesses the love story buddying between Nemesis and Wonder Woman, and so decides to keep Diana and Tresser in constant surveillance.
Recently, he has been seen composing an essay accusing prominent female historical figures of being Amazonian spies. It is then revealed that since his kidnapping by Circe that Doctor Psycho has been tampering with his mind, enhancing his suspicious nature. Doctor Psycho eventually manages to switch bodies with Sarge Steel.
