1x72 - Science Ninja Team Gatchaman

In Amazonia the old entemologist (insect researcher) Toda who is continuing his research, notices unusal behaviour in the locusts. He notifies every authority and department, but he is not taken seriously. Jinpei, who heard his story, returns with him to Amazonia. The unusual appearance of the locusts is a Galactor deed. With a guiding radio signal emitted by a locust mecha a swarm of locusts is made to attack the city. In the research hut of Toda, they are attacked by a swarm of locusts. While protecting the hut with a pesticide, they capture the mecha locust leading the swarm and Toda finds out the frequency of the radio signal. However, because of the interfering radio signals, Jinpei cannot contact Ken and the others. He comes up with a plan and sprays the form of the bird head shape into a meadow with the pesticide. Having received a message about the unusal appearance of the locusts, the God Phoenix has come to Amazonia. They discover the mark and join Jinpei and Toda. Because of the appearance of the God Phoenix, Katse accelerates his plan and releases mecha locusts and their locusts swarms, heading for the capitals of the world. Ken hears the story about the radio signal from Jinpei and has the God Phoenix emit the the same frequency. He lures the locust swarms released in the world towards the sea and blows them up with a rocket. Only Ken and the other know that the true credit belongs to the old scientist who piled up years of research and was ignored by everybody.
