The Arthur Dearborn incarnation of Sunturion first appeared in Iron Man #143 (February 1981) and was created by writers David Michelinie and Bob Layton, and penciler John Romita Jr.[1] The Mike Stone incarnation of Sunturion first appeared in Daredevil #224 (November 1985), and was created by writer Jim Owsley and penciller Dan Jurgens.

He accepted being subjected to this process so that he could guard and maintain the satellite Star Well I, developed as a means of gaining clean energy; the station's main flaw was that the need to maintain a human crew would not make the process cost-effective, but by making Dearborn something other than human they were able to minimize the demands of an organic crew as Dearborn no longer needed to eat or drink and required only minimal creature comforts.

Iron Man advises Sunturion that, despite his admiration for Dearborn's goals, the satellite is now evidence of Roxxon's criminal activities and must be confiscated.

Sunturion sacrifices himself to boost Iron Man's deflector beam, allowing the satellite to fall harmlessly into the Gulf of Carpentaria.

Sunturion locates Stratosfire and activates her "Zed Control": a Roxxon-implanted self-destruct device that dissipates her energy and reverts Dearborn to his human form.
