Opul Lun Sat-Yr-9 (also spelled Sat-Yr-nin) is a fictional character in the Marvel Universe.

Opul Lun Sat-Yr-9 was a dictator who ruled Earth-794 with her lover Kaptain Briton. When he fled from her, traveling to Earth-616 where he knew he had an identical looking counterpart, Earth-616's Captain Britain, she sent armored troops to retrieve him. They mistakenly attacked Captain Britain twice, but were repelled on each occasion, the first time by Britain and his ally Meggan, the second by Britain's sister Betsy. Sat-Yr-9 next hired the interdimensional mercenary group, the Technet, but Briton swapped places with Britain, and the Technet took the wrong man back to Earth-794. Britain later convinced the Technet of their error, but Sat-Yr-9 tried to stop them departing with him; the Technet slaughtered her soldiers, and the already psychotic Sat-Yr-9 became completely unhinged. After they departed, she started slaughtering her subjects, leading Roma to send Captain UK on a mission to overthrow and imprison her.

While Britain was on Earth-794, Briton was killed by Betsy when he tried to rape her.

Escaping to Earth-616 through a dimension gateway that had been opened by Widget for an unassuming civilian on Earth-616, Sat-Yr-9 incinerated her alternate reality counterpart, a businesswoman named Courtney Ross, and took her place. An example of interdimensional similarities, Ross was Captain Britain's ex-girlfriend. As Ross, she tried to create a rift between Captain Britain and his current girlfriend Meggan.

Opul Yun Sat-Yr-9 has not been a contender in any CBUB matches.
