Kagaku Ninja-tai Gatchaman

Synopsis

In the deep black sky, the blue-white moon is shining.

Suddenly, a meteorite falls down to Earth. According to analysis, the meteorite has the same composition as the moon. So Ken proposes approaching the moon in the God Phoenix to investigate.

Approaching the moon, the God Phoenix encounters a swarm of meteorites heading for Earth. Ken discovers a wrapped-up body in the middle of the swarm and, because this is not a meteorite, he attacks. But bird missiles have no effect. The body falls to the Earth, becomes a scorpion-shaped mecha, and attacks an oil refinery.

Following Nambu's instructions from Earth to find the source of the radio waves steering the mecha and the meteorites, Ken asks Jun to trace the signal they detected while the mecha was on its way to Earth.

The Science Ninja Team find the carrier sending out the control signal and leaves Ryu behind in the God Phoenix while they sneak inside the mecha. The other members question the commander, but he doesn't reveal anything. Joe loses his patience and fires carelessly into the control panels with a machine gun. Shortly after the Science Ninja Team escapes, the meteorites hit the carrier because the computer was destroyed.

Meanwhile on Earth, the Reddo Imparusu squad reports that the now-unguided scorpion mecha has been destroyed.
