Science Ninja Team Gatchaman - Season 1 Episode 61 The Imaginary Red Impulse

Ken is flying over the country Hontwall in his G1 plane. He is shocked when he sees the three Red Impulse planes. The figure in one of the machines is undoubtedly his father. When the Red Impulse commander asks him whether he should lead Ken to the new base, Ken gets into contact with Nambu. However, without listening to Nambu trying to stop him, Ken heads towards the base. Nambu orders the God Phoenix to investigate what is going on in reality. However, the God Phoenix encounters a mecha without the G1 on board. It is caught and brought to the base. Ken asks Red Impulse why he didn't let him know that he was alive. Red Impulse answers that it was because he was looking for the Galactor Headquarter. He says that he would like Ken to hand a briefcase to Nambu containing information regarding the location of some bases. When Ken brings the briefcase to Nambu, he learns that they didn't get any report from the God Phoenix. In order to make sure of the real intentions of Red Impulse, Ken goes back to the base. Because Red Impulse uses some delicate words, Ken understands that Red Impulse is an imposter. The commander is Katse in disguise and there was a transmitter installed in the briefcase. Ken gets angry and grabs Katse by the collar. However, Katse takes advantage of an opening and gets away. Ken is dropped into a subterranean prison under the floor. His abducted team mates are there. Ken escapes from the subterranean prison and contacts Nambu, telling him to get rid of the briefcase. The signal of the transmitter is interrupted and the mecha follows the small transmitter Ken attached to Katse. The Galactor base and the mecha end up attacking each other and are destroyed.
