Science Ninja Team Gatchaman - Season 1 Episode 100 Gatchaman 20 Years Later

A by-product of the Mantel plan is the Mantel condensation energy formula whose immense destructive power is kept a secret. In order to bury that equation forever, Ken goes together with Dr. Maxim towards the North Pole Sea in a cargo plane. Underway, a screw in the throttle comes loose and they get into trouble steering the plane. However, Ken puts in a clip as replacement and makes a forced landing. But the cargo plane is swallowed by a sudden crack appearing in the ice field. When Ken and the doctor come round, a physician appears before them. He explains that twenty years have passed since and that the present is a world where Galactor has been victorious. Ken is not convinced and is shown the devasted surface of the Earth where the slanting ISO building and the graves of the Science Ninja Team are. Moreover, Jinpei, now grown up and a Galactor member, shows up. He says that they had been defeated, but that Ken should accept this peaceful world, and convinces him to hand over the equation data. Dr. Maxim agrees to hand over the data. In order to take out the data inserted into his own body, he goes to a capsule in the cargo plane. Elsewhere, Ken goes to the cockpit and guesses that it's a Galactor trick since the clip did not get rusty. He sends a Bird Scramble. They corner Katse who is disguised as the physician, but Katse sets the self-destruct mechanism and manages to escape. The party goes in the God Phoenix to the North Pole Sea again in order to submerge the data there. The Doctor did notice the trick very early and he had the intention of eliminating himself with the data in the capsule.
