Kagaku ninja tai Gatchaman

Observatories and weather stations all over the world are attacked by UFOs. Additionally, authorities in the field of space communication are assassinated one after the other. Even Nambu can't guess the true intentions behind the incidents. In order to protect Dr. Kasshingu of the Irigutchi observatory, the Science Ninja Team goes to his whereabouts. But it's too late, they meet Dr. Kasshingu as he is already dying. The culprit is Galactor. Before dying, Dr. Kasshingu tells them that it was Dr. Raphael's Leapwave which made space communication possible. Upon hearing Dr. Raphael's name, Joe disappears from the sight of Ken and the others. Elsewhere Governor X is afraid of Dr. Raphael because he could unveil his secret. When X learns that Dr. Raphael is the only one able to send out the Leapwave, he goes berserk and orders Gel Sadra to pull the modulation waves of the Leapwave into his base and to reverse them. This way, he gives the nuclear missile launch systems a "go" order, with the aim of provoking a nuclear war. The whole world is plunged into a nuclear crisis without warning. Raphael has learned this and murmers "I am the one who called Sosai X from space. I have to take the responsibility." He then orders Joe to destroy the missiles of both parties with the antigravitational missile. A nuclear war is averted by a hair's breadth.
