Marvel has admitted that this character is a cheeky rip-off of Super-man. Introduced in Avengers #85 (1971) by Roy Thomas and John Buscema, with a few exceptions and different names, Mark Milton of Earth-712’s origins is pretty much the same as the DC character. He would join with Nighthawk and others to form the Squadron Supreme. He would clash with the Institute of Evil as well as the Scarlet Centurion, a young Kang. A contest between the Centurion and the 616 Grandmaster led to the pair tricking the Squadron in taking part in a Contest of Champions. This caused Grandmaster to create his own Squadron Sinister, which he used against the Avengers.

He would later meet the 616 Avengers who had travel to his universe by accident. While they would team up on occasion, the Squadron would often be manipulated into attacking the Avengers. They were later manipulated in taking over their own Earth until they were freed with the help of the Defenders. Sick of crime and injustice as well as wanting to end the world’s problem like hunger and even death, he led the Squadron in taking over their world and made many controversial choices. He was replaced by an evil version of himself but would escape and killed the doppelganger. Nighthawk and a team called the Redeemers led a team to bring down Hyperion. The battle resulted in Nighthawk’s death, but he convinced his old friend that they should give up on ruling the world. Hyperion and the Squadron surrendered.

At some point, the Squadron found themselves trapped on Earth-616 by the Nth Man. After a few adventures, they were able to return to their home world where they found it taken over by the Grand Directorate. They worked together with the son of Nighthawk and freed their world. He was later plucked out of his world by the Exiles to help them defeat King Hyperion. The Squadron were later tricked by Proteus into believing that the Exiles were abusing their powers and would clash with the Dimension hoppers. After finding out the truth, Hyperion suggested that Power Princess join them to help them defeat Proteus. His universe was later destroyed with Power Princess being the sole survivor.

Hyperion and the Squadron have been a popular choice of characters that people want as figures for a while. He would receive a figure as part of the Hit-Monkey wave. He was also supposed to get a Sentry swap figure but that was held back and later placed in the All-Father wave.
