The super-hero Hyperion, whose secret identity is "Mark Milton", is a member of the Squadron Supreme, originally introduced as the preeminent super-hero team of Earth-712. This character first appeared in Avengers (vol. 1) #85.
This Hyperion looks VERY similar to a villain named Hyperion (eventually identified as "Zhib-Ran") who was introduced as a member of the Squadron Sinister in Avengers #69 (Oct. 1969). The reason that the hero and the villain look so similar is that the Grandmaster (one of the Elders of the Universe) created the Squadron Sinister based on the Squadron Supreme.
Some indexers refers to Mark Milton (who was introduced in Avengers #85) as "Hyperion I" because he was the "original" Hyperion and Zhib-Ran as "Hyperion II" because he was the copy. Other sources refer to Zhib-Ran as "Hyperion I" because he was introduced first, and "Hyperion II" because he appeared in a later-published comic.
