Iron-Arms was a foe of Captain Atom.
Iron-Arms had incredibly powerful robotic arms powered by a device he wore on his back. It also included a gyroscopic device which allowed him to keep his balance despite the weight of his arms, and a force field.
- This version of Iron-Arms (Earth-Four), 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.
