==Plot==
Hideki Go is having recurring nightmares of the original Ultraman's imfamous final battle with Zetton. He wakes up and gets a call from an unknown figure. He is ordered to go to a baseball stadium. Meanwhile, Jiro, and Rumiko wake up in a baseball stadium and try to escape, but are stalled by Alien Bat.
Go arrives at the stadium, and encounters Zetton II, under Bat's control. Go 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 Go 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 Go leaves abruptly. 
Go 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. MAT manages to rescue the Sakatas, but Go is shot down by Zetton. Meanwhile, Bat transforms into a giant and the duo start to continue to rampage throughout the city.
Ultraman Jack, touched by Go and MAT's courage allows the former to transform one last time.
With the assistance of MAT, Ultraman manages to stab Alien Bat and kill him. He then destroys Zetton with his Ultra Hurricane and Spacium Beam, avenging the original Ultraman's defeat.
Go, presumed to be dead, has a funeral service held by MAT and the Sakatas near the ocean. When MAT leaves, Go appears to Jiro and Rumiko one last time. Go knows he needs to go to M78. He tells Jiro to recite the 5 Ultra Oaths but he refused to. Go saids goodbye to Jiro and transforms into Ultraman. Jiro shouts the 5 Ultra Oaths at both Go and Ultraman while they vanish into the sky and return to to M78.
