EPISODIUM
Strange radio waves attack people together with an aurora. Afterwards they run amuck and cause grave accidents. While fishing, Ryu is also bathed in these radio waves. Because Ryu's speech and behaviour are strange after he comes back to the base, an investigation is conducted. It results that Ryu's brain waves are like those of a cat.
Additionally, Nambu is touched by those radio waves as well. In a rage, he tries to activate the switch for the self-destruct mechanism of Crescent Coral. Joe punches him out.
Ken and Joe take Ryu with them and go to the place where Ryu got hit by the radio waves, in order to find clues. Because they can't get any answers, Joe gets angry and punches Ryu, who then hits the boat's panel and suffers an electrical shock. However, this causes him to return to his true personality. They think that an electrical shock might also work in Nambu's case, but because Nambu's brain waves keep changing their frequency, they have to destroy the mechanism producing the radio waves. The God Phoenix is therefore mobilised, and they seek the suspicious aurora Ryu saw.
What they finally find is Thundersaurus, but the Science Ninja Team has to fight hard because the mecha's barrier of radio waves. A rocket is fired, but gets stuck and does not work. But as the mecha increases its electrical voltage, the blind shell explodes. Jun has made all the necessary installation to create the situation in which the increased voltage causes an explosion. The mecha is destroyed and all the people running amuck become their usual selves again.
