- Iron Hammer was a Nazi villain of the Blackhawks who returned to battle them years after World War II.
- This version of Iron Hammer, including all history and corresponding appearances, was erased from existence following the collapse of the original Multiverse in the 1985–86 Crisis on Infinite Earths limited series. Even though versions of the character may have since appeared, this information does not apply to those versions.
