Kagaku ninja tai Gatchaman

The town "Ghost City" has been destroyed 10 years earlier by environmental pollution. Communication with an investigation team sending data from there is lost. The Science Ninja Team goes there in the God Phoenix, which uses a soft skin (membrane) to protect it against the pollution. But as soon as they enter the city, they meet a Galactor attack. As it turns out, there's a base here. Nambu orders the U.N. military forces to attack. It seems everything is cleared after the attack. In reality however, a jellyfish lens created by Sosai X continues to grow at the bottom of the sea near the city. It uses the polluted sea water as its amniotic fluid. After finishing its growth, the jellyfish lens which turns the sunlight into energy a few hundred times stronger, completely destroys fighter planes from the U.N. forces. It then starts to attack the cities on earth. The God Phoenix dives into the sea near the city and discovers the base and the hiding jellyfish lense. They attack with missiles, but even though they destroy the base, the jellyfish lense flies out of the sea, pursuing the God Phoenix. The membrane protecting the God Phoenix is peeled off and puts it in a difficult situation. Just then, the Red Impulse group gets Nambu's instructions that in order to dissipate the poisonous gas the jellyfish lense breathes, they should throw high pressure oxygen at it. Protected by the Red Impulse machines, Ken flies they fiery phoenix into the jellyfish lense. The high pressure oxygen goes up in flames and the jellyfish lense burns to ashes on the surface of the sea.
