Hyperion's History
Early Life
Hyperion is a superhero from an alien world, where he, along with his team, ruled with an iron fist. When the people rejected their rule, The Squadron Supreme forced Doctor Spectrum to destroy their planet. At some point, the Squadron Supreme separated and Hyperion began his search for a new planet he could "save".
Hyperion
Hyperion arrived on Earth as it was threatened by a giant meteor (implied to be the remains of Hyperion's planet. Although the Avengers were able to stop most of the asteroids, Hyperion destroyed the largest one, an "earth-killer", making him the day's hero, even earning the admiration of J. Jonah Jameson. Not long after, Hyperion invited the Avengers, who had taken an interest in the new hero, to his Citadel, where he shared with them his "tragic" story. However, the Avengers soon saw through his lies and became worried about Hyperion's extreme ways after witnessing him deal with the Wrecker. Although Hyperion was a worthy foe, the Avengers were able to take the rogue hero down, and imprison him in a place where he could never break out.
Cabal
Some time later, S.H.I.E.L.D. was keeping Hyperion contained on the Tri-Carrier. Interested in his abilities, the Red Skull and his Cabal freed him from his prison and asked him to join them. Hyperion, wanting to get revenge on the Avengers for trapping him in the first place, accepts the offer. Hyperion serves as a member of the Cabal and aids the Red Skull while having the chance to take revenge on the Avengers. When he is saved by Iron Man from Red Skull's trap, Hyperion and the other Cabal members aid the Avengers in defeating Red Skull.
Nighthawk
It was revealed that Hyperion's team didn't perish when Nighthawk appeared on Earth. Nighthawk has mentioned about knowing of Hyperion's time with the Cabal and considered him the "hammer" of the group. At the end of the episode, Hyperion appears on the Tri-carrier and frees Nighthawk with the intent to reform their group.
The Dark Avengers
Using the Reality Gem, Doctor Spectrum alters reality so the Avengers are all criminals with darker costumes and the Avengers Tower is headquarters of the Squadron. Due to a spike in energy, Iron Man sees the real reality and manages to convince his team to come together. However Spectrum has created a machine that will give him complete control over reality, and plans to alter history so the Avengers were never born. Captain is able to get a hold of the stone and revert reality back to normal. The Squadron leaves with Nighthawk activating explosives placed at the base of Avengers tower. The Avengers manage to prevent the structure from falling onto New York in time for J.A.R.V.I.S. to activate the repair systems.
Terminal Velocity
While Speed Demon put a belt on Hulk which not only gave the Green Goliath super speed, but also turned him into a bomb, Hyperion kept the rest of the Avengers busy.
Spectrums
While the team of Hawkeye, Black Widow, Falcon, and Hulk were on the Citadel, they found a holographic recording of some security footage. In it, we learn Bill, better known as Dr. Spectrum, was the only member of the Squadron against destroying their home-world. However both Hyperion and Nighthawk forced him to reveal the Power Prism, which ultimately reduced the planet to debris.
Avengers' Second To Last Stand
The Avengers are challenged by the fully formed and incredibly powerful Squadron Supreme for a battle that will end with only one team as the victor.
Avengers Underground
Believing to have bested the Avengers, each member of the Squadron took a part of the world, where they wouldn't have to see one another. While ruling England, Hyperion was weakened by Captain America using the power prism to turn the sun blue, allowed Black Widow to effortlessly beat him. However Nighthawk revealed he only revived Nuke to supercharge Hyperion, giving him more strength then ever. Hyperion then headed down to the center of the Earth in order to destroy it, believing the planet wasn't worthy of their rule. While Iron Man dealt with Nighthawk, the other Avengers fought Hyperion with Ant-Man's use of using the underground insects to great effects. It was mentioned that all members of the Squadron were locked up in the Vault.
