Ultra Galaxy Fight: New Generation Heroes (2019)

In a different planet, Ultraman X and Geed were defeated by an identical pair of black Ultramen while Zero and Grigio were ambushed by Ultra Dark Killer. To confront the threat of the Dark Killers, Taro assembled the help from New Generation Heroes. The entire event would eventually lead to the cold opening of Ultraman Taiga, which had the seven of New Generation Heroes (excluding Grigio) themselves chasing against Ultraman Tregear.
