Kagaku Ninja-tai Gatchaman

Synopsis

While flying, Ken is surprised to encounter the plane of the Red Impulse commander. He pursues him, but Red Impulse gets away using some superb flying technique; Ken longs to be able to use similar techniques.

The Science Ninja Team gets order to guard the super powerful plane "Blue Hawk", pride of the country Toritan. But the crew of the plane has been killed before take-off and replaced with Galactor members.

Nambu learns of this situation after take-off. He mobilizes Red Impulse in order to protect the Science Ninja Team from the Blue Hawk, since it is more powerful than the God Phoenix.

The God Phoenix continues to accompany the Blue Hawk without knowing the situation on-board. Red Impulse appears, attacking the Blue Hawk and, after shooting a timebomb into it, disappears again. Ken sees that and firmly believes that Red Impulse is actually an enemy. Ignoring Nambu who wants to stop him, he pursues Red Impulse alone in the G-1.

While Ken is away, the other four members get abducted and taken to a base located in a volcano. Ken however, follows Red Impulse, who in turn is following the signal emitted by the time bomb. They arrive together and save the team just before they're executed.

Nambu tells them that Red Impulse is a friend battling on their side. The G-1 and the Red Impulse plane fly through the sky wing-to-wing, reminiscent of bird parents flying with their children. Nobody at the time knows the meaning of the tear appearing in the Red Impulse commander's eye.
