Yullian
Late in the series, 80 is joined on Earth by the Princess of the Land of Light (the Ultra Planet), Yullian (ユリアン, Yurian?), 80's childhood friend (and in Ultraman: Super Fighter Legend, his girlfriend). She originally comes to Earth to warn 80 that King Galtan the Great is planning to assassinate him, but she ends up sticking around for a while and joins UGM (replacing Emi Jouno, who had been killed in action). She assumes the identity of Ryoko Hoshi. While not using any attacks as Yullian (other than Double Power, a combined attack with 80), she does shoot the Princess Ray, an infrared beam fired from the fingertips, as Ryoko.
She later makes a cameo appearance in the first episode of Ultraman Mebius and also participates along with several other Ultras in fighting against Ultraman Belial in the film, Ultra Galaxy Legends but she fails to stop Belial and is frozen once he steals the Plasma Spark and remains frozen until Ultraman Zero returns it.
