There is little know about Hyperius. Native of earth-8, he joined earth-5 Captain Marvel to help to save the multiverse from the menace of Mandarkk. His relationship with other inhabitants of earth-8 and their main team, the Retaliators is unknown. For the natives of earth 8 Hyperius right now is missing.
If Hyperius has even been member of a team analog to the Justice League of America, (including doppelgangers of their teammates) is unknown but not dismissible.
