Overview: The Jet Cutter, developed by the ISO to gain energy without causing pollution, is stolen. Nambu gives the order to recover it. Ken opposes him, asking whether they have to pay for the faults of the ISO. It's because of a lack of reason which makes him think that he wants to attack the enemies of his father. Jinpei starts crying at the argument between the two men. When Ken sees this, he reluctantly agrees to be mobilized.
Ken and Joe enter the cave where Mekabutta disappeared and are attacked by buddha statues acting as surveillance devices. Ken ignores Joe who suggest they should return to the God Phoenix for the time being, and he runs towards the interior. Joe follows him, but is hindered by the fire being spouted by the buddha statues. Ken discovers the Galactor base and Mekabutta in the interior of the cave, but gets knocked unconscious when he touches an iron grating with high voltage which comes falling down. When Ken wakes up in the God Phoenix, Mekabutta has already left the base and is heading towards an uranium mining factory.
The God Phoenix pursues Mekabutta, but the Jet Cutter is loaded aboard the mecha and it spouts continuously heat of 40'000 degrees celsius from its four faces, on each side one. The God Phoenix has to fight hard against it.
But Ken, using the multiple firebird figure, lets the Jet Cutter shoot without pause, thus causing Mekabutta to self-destruct because of overheating.
In the God Phoenix, on the way home, Ken apologizes for being hotheaded because of this desire to fight the enemies of his father. Joe tells him that if they defeat Galactor one by one, Katse will be cornered.
