Arthur Dearborn began his career as a design engineer for the Roxxon Oil Corporation. Dearborn designed a space station that would serve as a reception and storage unit for solar radiation. The solar energy would then be converted into microwave energy, and transmitted down in a tight beam to receiving antennas on Earth. Roxxon liked the idea, but the company accountants said that the cost of keeping a crew on board, to repair and evaluate problems, would make it too costly.

For this reason, Dearborn volunteered for some experiments being done by one of Roxxon\\\'s subsidiaries, the Brand Corporation. The experiments converted Dearborn\\\'s body mass into microwave energy that he could mentally control. Since Dearborn no longer needed food or air to survive, he volunteered to become the entire crew of his solar space station. Roxxon agreed, an built the space station, Star Well I, in orbit. The space station was provided with radar jamming devices, to prevent intervention from governments or rival corporations. A few months after the station be came operational, there was an accident. A transmission malfunction occurred, bathing Allantown, Iowa with the microwave beams, killing everyone.

Iron Man traced the microwave energy to Star Well I. He met Sunturion in his first generation Space Armor, whose real ID was Arthur Dearborn. IM accused the Star Well of causing the deaths, and Dearborn admitted to a slight malfunction at the time of the deaths. Dearborn insisted that the lives of a few hundred people meant nothing since they were developing a power source that could save billions. Before Shellhead could shut down the station, it was attacked by Russian \\\"killer satellites.\\\" Iron Man and Sunturion worked together, and defeated the satellites. A Roxxon leader, Mr. Hale, then contacted the space station. Finding out about about Iron Man\\\'s presence, Hale tried to activate the station\\\'s self-destruct device, but IM had already disconnected it. Iron Man then set out to remove the station\\\'s solar panels, rendering the station\\\'s solar energy gathering powers. Sunturion intervened, and during the battle between the two men, the Star Well was knocked out of orbit. As the massive station began to fall to Earth, IM calculated that its debris would fall right on top of Sarasota, Florida. Iron Man tried to use his deflector beam to push the Star Well away from its course, but it wasn\\\'t powerful enough. Sunturion asked Iron Man to try again, which he did at the same time Sunturion used the energy that composed his body to increase Shellhead\\\'s deflector beam. This time it worked, knocking the Star Well into the Gulf of Mexico. Unfortunately, Sunturion\\\'s body was apparently totally dissipated.

Roxxon lost control of another employee, Stratosfire, who had been given microwave powers like Sunturion. This time, they successfully reintegrated Sunturion and asked him to stop Stratosfire. After stopping the stunned Iron Man from being killed by Stratosfire, Sunturion and IM joined forces to stop her. Iron Man and Sunturion next fought Stratosfire during the launch of a space shuttle containing some orbital \\\"Star Wars\\\" technology. While Shellhead distracted her, Sunturion snuck up behind her and put his hands inside her body. Sunturion then activated a special self-destruct device built into Stratosfire\\\'s body. She had discovered the device and had been jamming the signals to it. Sunturion was caught in the explosion which apparently destroyed Stratosfire. Sunturion reverted to his human form and began to fall, but he was saved by Iron Man. The explosion somehow reverted Dearborn\\\'s molecules back to normal, causing him to lose his microwave powers.

Dearborn\\\'s current status remains unknown.
