Dr. Misuno, a Galactor, succeeds in diminishing the earlier invented detection device, which discovers the electrical waves emitted when the Science Ninja Team transforms. Galactor plans to use it in an operation to track down the Science Ninja Team and follow them to their base. They rebuild some previous mechas and have them rage everywhere. Catching the short moment when the Science Ninja Team transform, they succeed in their plan. The Science Ninja Team, not knowing the Galactor plan, reunites in the God Phoenix, and wants to attack the mechas. However, Nambu suspects it's a Galactor trap and orders them to return to the Crescent Coral, leaving the mechas to the UN troups. However, the God Phoenix is followed by some crab-shaped bulldozers. When they notice their followers, Cresent Coral is already in sight. They contact the base and tell them to change their location. The base and the God Phoenix are however already surrounded by some mechas. The crab bulldozers aim at the propulsion system of the base, but G-4 is mobilized and protects the system from the bulldozers. Desperately returning the fire, they manage to defeat the mechas and the base is saved. But Crescent Coral has been detected and, additionally, the secret of the capability to change its location is known as well. In the ears of the Science Ninja Team, the continuously approaching steps of Galactor are resounding.
