Hyperion, Marvel's super-powered pastiche of DC's Superman, has played both hero and villain in his many comic iterations. Different versions of this character have acted as leader of both the Squadron Supreme and Squadron Sinister, pursuing everything from protecting the public to ruling over them as an unquestioned god. Touring his many comic appearances will help readers understand Hyperion's varied personalities, where his current allegiances lie, and even how he wound up as one of the mightiest Avengers.
Hyperion's powers are pretty straightforward; if Superman can do it, Hyperion can do it. Same goes for the evil Hyperion, Zhib-Ran. Crafted by the tournament-hungry Grandmaster in 1969's The Avengers #69 with motives to defeat the infamous Kang the Conqueror. Grandmaster weaves false memories into Zhib-Ran, telling him that he's a hero named Hyperion. Thus Zhib-Ran thinks he's doing good as he squares up against Thor. Happily, Thor is quick to beat Zhib-Ran and Grandmaster flees, leaving his Squadron Sinister behind.
After working for the evil alien Nebulon, Zhib-Ran's brainwashed mind is cured. For a stint it seems he'll stay a newly reformed heroic Hyperion. He briefly works with Dr. Strange and Black Panther, but it doesn't last. Evil Hyperion returns, eager again to destroy both Earth-612 and Earth-712. It's these intentions that prompt the classic Hyperion vs. Hyperion battle.
Since Hyperion exists on many alternate Earths, Zhib-Ran is able to impersonate one of them for several years before being bested by his heroic self. The evil Hyperion is killed, defeated for good this time. But it's not the last readers see of Marvel's evil Superman. The next time he graces the comic scene, he's again created - this time in SHIELD Agent Phil Coulson's government-sponsored lab. Before that, however, a new Hyperion entered the scene. Featured in Jonathan Hickman's Avengers #1, this Hyperion is from Earth-13034, plucked from his damaged reality by AIM and quickly joining the Avengers. An Eternal who went by the human name Marcus Milton, this Hyperion added vital might to the Avengers roster as they pushed back against the end of the Marvel Multiverse. The Avengers finally had Marvel's Superman as their first line of defense, though even he was ultimately unable to defeat the sinister Beyonders, who were circumvented by other means.
It's likely this individual who provided the genetic materials that Coulson uses to create his own "evil" Hyperion. In 2018's Avengers #10 the Squadron Supreme are reimagined. Crafted by the devilish Mephisto and the Power Elite, their purpose is to protect those loyal to Coulson and United States defense - there's even a nod to the idea of them being Marvel's version of the Justice League, with Coulson calling them DC's finest heroes (though he's referring to Washington.) This brainwashed and programmed version of Hyperion may be misguided, fighting to protect American lives but not feeling as responsible for the rest of the world, but he isn't exactly a villain. Still, given who created and controls him, Hyperion is likely to be used for more evil ends before he can be stopped.
