Sarge Steel was a private detective who was later recruited by the C.I.A. He had a sculpted steel fist (later replaced by a fully functioning steel prosthetic) in place of his missing left hand, and had a number of outlandish adventures over the course of several decades, at one point encountering the Sentinels.
- This version of Sarge Steel, including all history and corresponding appearances, was initially erased from existence following the collapse of the original Multiverse in the 1985–86 Crisis on Infinite Earths limited series. However the ending of Convergence retroactively prevented that collapse, saving all the alternate realities, though in an "evolved" form. Even though versions of the character may have since appeared, this information does not apply to those versions.
- Having enlisted in the United States Army in 1960, Sarge Steel was likely born in the year 1942 or 1943.
