History
Hyperion was the baron of Utopolis and leader of the Squadron Sinister, a group of superhuman villains. As ruler of his domain, Hyperion pursued an aggressive foreign policy; secretly allying his domain to the Bar Sinister in opposition to Higher Avalon and rapidly conquering his neighbours, annexing eight provinces in six weeks.[1][2] Unbeknownst to Hyperion, members of his Squadron Sinister were conspiring against him, most notably Nighthawk and Zarda.[1]
When a Thor visiting Utopolis was killed, Hyperion soon became aware that someone was trying to frame him.[3] Despite this, he was unable to identify the traitor in his midst and was outplayed by Nighthawk, who succeeded in killing him.[4]
