Counterattack! The Subterranean Torpedo Plan

Katse is happy that he has defeated the Science Ninja Team. An order comes in from X to make sure that the Science Ninja Team is dead. Meanwhile, the Science Ninja Team spends its days at Nambu's villa. Without means to do anything after the heavy blow of losing the base, the data of the Mantel plan, and a place to produce missiles. Then the message is received that a tourist city without any strategic value has been attacked. The Science Ninja Team wants to get mobilized, but Nambu stops them and leaves the field to the UN troups. Despite the attack on the city, the Science Ninja Team does not appear. Katse is convinced that the Team is dead and proceeds to his operation of destroying UN bases and factories with subterranean torpedoes. Based on the destroyed locations, Nambu derives where the torpedoes were launched from and sends the Science Ninja Team there. The Ninja Team sneaks into the base and discovers there a storage room for the torpedoes. Joe collects everybody's small detectors and installs them on the torpedoes. During the celebration for the destruction of the Science Ninja Team, Katse is in the middle of a speech with a tape in his hand that came in with X's latest plan for conquest. Katse and the Galactor members are startled by the Science Ninja Team appearing there. Seizing the opportunity, they grab the tape. Katse orders the torpedoes launched and the base destroyed, then flees from the base. The God Phoenix follows the mecha and fires the last Bird Missile. A transmitter has been installed in the missile and the torpodoes go one after the other in direction of the mecha. They bring the tape back to Nambu, but when they try to play it, it disintegrates in a column of white smoke.
