The Great Decisive Battle! The Super 8 Ultra Brothers version of Ultraman Jack (ウルトラマンジャック, Urutoraman Jakku?) is an Ultra who was born from Hideki Goh.


When the other Ultras were having difficulty fighting Giga Chimera, Goh and his friends change into their Ultra forms and helped the four other Ultramen. They later defeated Giga Chimera with the Superior Strike attack. However, Black Silhouette appeared before them, telling them he would always be alive if there was still a darkness in humanity's hearts. However, Black Silhouette was soon defeated by the eight Ultras' Superior Myth Blaster.

Later, Go and his wife would ride their plane and travel with everyone to Nebula M78.

Glitter Ultraman Jack

Ultraman Jack's glitter Mode only appeared in the climax of the Superior Ultraman 8 Brothers film. After the eight Ultramen defeated the Giga Chimera, the dark wizard appeared. The eight all went into Glitter mode and combined their beam attacks to destroy the dark spectre. It was only used by an alternate Ultraman Jack and is not considered canon in the Showa continuity.

Will Power: Hideki Go waves or holds one of his arms above his body and he transforms into Ultraman Jack.


  • Like all Ultras in this universe, Ultraman Jack has a green color timer instead of blue.
