The ISO discovers a new energy source in the Himalaya, but an investigation troop sent there is annihilated by the Yeti. Because of several rumours about Yetis, Jinpei goes to the Himalaya alone. There he is attacked by the Yeti, but it is a Galactor Yeti Mecha. The God Phoenix goes to the Himalaya to look for the missing troop according to Nambu's orders. They get the message from Jinpei about the apparition of the Yeti and head towards the location this message came from. Elsewhere, matters have developped in such a way that Jinpei has been saved by Galactor members and is now working as a servant in the base. While working, he secretly sends a bird scramble signal. Additionally, when he brings food to Katse's chamber, he hears there Katse speaking with X. The God Phoenix appears in the vicinity of the base and Galactor turns towards it, attacking it with missiles and flame throwers. However, because of Ken's tactic the God Phoenix keeps turning back and while it is continously shot at, an avalanche gets started and the base is hit hard. The God Phoenix breaks into the base. Ken and the others corner Katse again. Ken tears away Katse's mask. Katse covers his face and from behind him, X appears with a flash and introduces himself as the ruler of Galactor. The Science Ninja Team is blinded by the light and they lose consciousness. When they wake up again, Katse and X's form have disappeared. A certain anxiousness arises now that they are aware of X's existence. The mountains of the Himalaya still enclose that secret.
