The Hyperion was a human spacecraft. It was sent to investigate operations at Skybase One. Upon its approach, Jo Grant informed the crew of the Marshal of Solos' recent actions and requested that he be removed. The Hyperion then docked with Skybase One and began refuelling. Jo, Ky and Cotton escaped Skybase One's fuel lock by climbing through the Hyperion's fuel probe. (DW: The Mutants)
