The Baltan ship, thought to have been driven off in episode 1, returns and launches three more pods to Earth. This time, however, the Baltans have decided to completely obliterate WINR and Ultraman Powered by sending a regenerated Red King and the bladed monster Dorako to do their dirty work for them.
An energy company has been tracking what they believe to be a moving underground uranium mine. Mr. Keins, the head of the company comes to WINR after one of his drivers is seemingly swallowed by the ground itself. WINR arrives at the site where the company plans to blast open the uranium mine with dynamite. However, instead of a mine, they end up bringing a giant monster called Gabora (who isn't referred by the name) to the surface.
A pair of seismologists working in a remote cavern have detected unusual underground activity. Theresa Beck & Kenichi Kai are sent to investigate and Kai disappears when another tremor rocks the cavern. While Beck tries to console herself for losing Kai, the rest of the WINR team has determined that the seismic activity is being caused by a strange object moving underground toward the city.
While WINR tries to ascertain the implications of the recent Baltan attack and the appearance of the silver and red giant, farmers in a rural community begin reporting that their cattle have been disappearing. WINR launches the Mobile Transport Carrier (MTC), their large roving command center and discovers that the animal disappearances are being caused by a creature burrowing under the ground.
