When the other Ultras were having difficulty fighting Giga Khimaira, Seiji and his brothers change into their Ultra forms. The four original Ultra Brothers: Ultraman, Ultraseven, Ultraman Jack and Ultraman Ace revived the defeated Mebius. Later they all joined Tiga, Dyna and Gaia against the Giga Khimaira. They defeated it with the Ultra Superior attack. However, Black Silhouettes appeared and combined into the Giant Black Silhouette, telling them he would always be alive if there was still darkness in humanity's hearts. Mankind's determination allowed the eight Ultras to achieve their Glitter forms, and Giant Black Silhouette was soon defeated by the eight Ultras' Superior Myth Blaster.
Later, Hokuto and his wife ride their plane and traveled with everyone to Nebula M78.
