Meanwhile, Jiro, and Rumiko wake up in a baseball stadium and try to escape, but are stalled by Alien Bat.
Goh arrives at the stadium, and encounters Zetton II, under Bat's control. Goh tries to transform into Ultraman, but unable to. He hears the original Ultraman's voice and tells him that Zetton was the only monster that he couldn't defeat and if Goh rushes in to battle he will lose just like him. Alien Bat then tells him of the bat invasion of the land of light and that the ultra brothers will be unable to stop them. He threatens to unleash Zetton II on the city. An angered Goh leaves abruptly.
Goh reports his findings to his teammates at MAT, who decide to have one contingent fight Zetton, who is rampaging in the city, while another contingent rescues the Sakatas.
