Ep. 55: Galactor uses mini-submarines to pollute the Tarushia Sea with PCB, forcing Ken to infiltrate their operations.
Galactor forces Nambu and the Science Ninja Team to choose between their lives and sea pollution by PCB. The God Phoenix pretends to agree, but Ken discovers three tankers controlling mini-submarines and sneaks aboard using a loaded mini-sub. Inside, he finds cleaning work for returning submarines and is discovered by Galactor. After defeating enemies, Ken pursues Katse as the tankers merge into a huge tanker emitting a magnetic force that cracks the God Phoenix. Katse activates a self-destruct mechanism and escapes via a rocket through a floor passageway. Ken and Galactor members exit into the sea, where the members die upon touching the flowing pollution matter. Ken is narrowly saved by a mechanical arm from the God Phoenix. Finally, Galactor releases cleaning capsules into the sea, restoring its former beauty.
