When Last We Left Our Beyond-Human Protaganist...
...once known as Gordon Pruett, he had been transformed by a Monolith into a "New Seed" who now wanders time and space the way you and I wander local streets...
The remaining three issues after this introduced X-51 aka "Mister Machine", renamed "Machine Man", and now an integral part of the mainstream Marvel Universe.
You can read them HERE, HERE, and HERE, and unless you have the actual issues of 2001 in your comics collection, this blog is the only place I know of where you can do so!
Though Marvel has reprinted the later ongoing Machine Man series, it can't reprint the three issues of 2001 introducing the character, nor can it reference the Monolith's participation in the character's origin due to licensing issues!
NOTE: This wasn't the first series set in the 2001: a Space Odyssey universe!
In 1971, Polystyle's comic weekly Countdown introduced an ongoing two-page strip set sometime after 2001...
It was much more in the Dan Dare/Buck Rogers action/adventure vein than the movie.
