There's a new kind of plane that does not pollute the environment. In the middle of Ken's test flight of this ISO-developed plane, he is attacked by a biplane, piloted by a man who introduces himself as "Katzen Berig". Katzen Berig lashes with his whip at the ISO plane, causing it to crash, but Ken saves himself just in time by deploying a parachute.
Nambu suspects from the name that Galactor is involved and orders the God Phoenix to attack immediately, but the God Phoenix's tailfin gets damaged by the whip. Analysis of the material stuck in the hull of the God Phoenix reveals that this kind of metal, called "super metal whisker", is something that has been researched by the ISO, but not manufactured. Nambu is taken aback at the scientific power of Galactor, but when the production factory is discovered, he gives the Science Ninja Team the order to destroy it.
While the Science Ninja Team conducts a search with the God Phoenix in a mining area, they detect a huge mine. When they discover that this is where Galactor's secret factory is located, they sneak into it. By the end of the battle, they have succeeded in destroying the computer and the nuclear reactor. They try to make their getaway in the God Phoenix, but are caught by the strong magnetic attraction of the mine. They switch to jet propulsion and escape by a hair's breadth, leaving the exploding factory behind them.
