Machine Man, aka Robot X-51, aka Aaron Stack. Created by Jack Kirby for one of the issues of 2001: A Space Odyssey. First encountered him as a backup strip in Marvel UK's Transformers comic, where he went to the distant future of 2020, and met Arno Stark, the Iron Man of 2020. Tried and failed to do the King justice by emulating his heavy shading style.
