The race between Black Ghost and the Cyborg team has started. Their goal is to find the head that controls robot 0013 and they hope to find some information on it. The submarine sent by Lord Kulo gets the head before the heroes but Joe follows it with the dolphin. The sailors of the submarine notice that they are being followed and leading the Cyborg team to the Black Ghost weapon experiment called Dragone Trigone. A battle starts there with both the little sub with the robot head in the cargo and the great submarine sent out by the Black Ghost. They should kill the Dolphin however they only manage to kill each other with two excellent torpedo shots thanks to Joes good maneuvering skills. Just before the explosion the heroes track a S.O.S. signal sent from the South Pole.
