Jokuu was sent by Yapool along with Bryer to fight Ultraman Zach. The two made their entrances into the arena, after Bryer was defeated, Jokuu was next to fight Zach. It seemed Zach had no chance, as from his battle with Bryer, his feet were frozen, and to make matters worse, if that ice and Jokuu's web combined, it would turn into strong stone, which Jokuu did. Jokuu cut, punched and kicked Zach. But Jose shot the stone with a Photon Laser, freeing Zach. Now that they were even, Zach won by punching Jokuu in the chest, his guts spilling out of his chest.
