exists on Earth-1124, where she is visited by the Deathlok of Earth-7484 and the Killraven of Earth-691, attempting to seduce and offering herself to Killraven, although he ultimately resists her and returns to Earth X. When Kaptain Briton flees to Earth-616, where he has an identical looking counterpart, Captain Britain, Sat-Yr-9 sends armored troops to retrieve him. They mistakenly attack Captain Britain twice, but are repelled on each occasion. Sat-Yr-9 hires the interdimensional mercenary group, the Technet, but Briton swaps places with Britain, and the Technet take the wrong man back to Earth-794. Britain later convinces the Technet of their error. When Sat-Yr-9 tries to stop them departing with Britain, the Technet slaughter her soldiers; the already psychotic Sat-Yr-9 becomes completely unhinged. She kills her subjects, leading Roma to send Captain UK on a mission to overthrow and imprison her. Later, Sat-Yr-9 seizes the opportunity to escape when an unassuming dimensional traveller from Earth-616 inadvertently enters her cell; she kills him, steals his suit and exits through the portal he came through.

Sat-Yr-9 later unmasks herself, revealing to Brian that she murdered Courtney and has taken her place; he swears revenge on the impostor for the crime as she and Jamie leaves. Still posing as the Earth-616's Courtney Ross, she has joined the Hellfire Club as its White Queen, with Viper, a former HYDRA assassin, as her self-proclaimed "White Princess" and bodyguard. Someone claiming to be Courtney Ross has been seen in issues of Uncanny X-Men during the House of M crossover, as well as in the early issues of New Excalibur. Upon meeting Captain Britain during the House of M event, she was attacked and was accused of being her impostor, Sat-Yr-9, but upon revealing that she did
