Katse, opposed to Sosai X's orders to destroy the Mantle Plan, asks whether it wouldn't be better to conquer Earth after the Mantle Plan was finished. X promises to Katse the rank of President Z and lets him start the operation. But behind his back, X laughs and says that Z is a symbol for murder.
Institutions of the Mantle Plan are attacked one after the other by a jellyfish mecha. The God Phoenix faces it, but its missiles have no effect. On the contrary, the launching ramp gets hit. The God Phoenix wants to escape with the multiple firebird. But mines are released upon the God Phoenix and it is wrapped in flames in no time at all. The God Phoenix makes a forced landing in the desert and explodes in the end.
While the rebirth of the God Phoenix is being carried out by the ISO, the Science Ninja Team has no means to intervene and can only watch Galactor's attacks. They are in an irritated state when they receive the message that the revived God Phoenix is finished. Each of their individual mechas has been outfitted with a weapon. But Nambu tells the five team members that the purpose of those weapons is not to kill, but for defending themselves.
When the message arrives that the jellyfish mecha is attacking the ISO headquarters, the God Phoenix is deployed immediately. Guiding the mecha to a mountain region, they defeat it with the weapons on their invidivual mechas and the Super Bird Missiles.
But in Ken's heart there is the doubt that if the development of new weapons continues, peace might still be far away.
