Hyperion

Hyperion is a member of the Cabal and leader of the Squadron Supreme.

With the Sqaudron Supreme
When he and a group of other heroes decided to take control of there world, but it was ultimately destroyed. He then went searching for another planet to save, and found Earth.

Battling the Avengers
Hyperion arrived on Earth as it was threatened by large meteors (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 himself. He was later broken free by The Red Skull, and the Cabal, with whom he joined. He helped them battle the Avengers some more, and took much offense to the Red Skull's treachery. He is still with the Cabal to this very day.
