Gatchaman

A shining object collides with the luxury liner Queen Margareth. A child with special chromosomes is abducted from the sinking ship. Governor X has returned and with the help of his scientific power the child grows very quickly. It is given the name of Gel Sadra and enters on the task of being the new Galactor leader. Soon, numerous scientists and soldiers begin to disappear. Elsewhere, Dr. Nambu has already predicted the counterattack of Galactor. He has had the Science Ninja Team resume their activities at their underwater carrier base G-Town, which capable of changing its location. The revived Science Ninja Team greets Getz as the new G-2 and is ordered by Nambu to investigate some ruins on Easton Island. But Getz is a member of the enemy forces. The ruins are a trap and Gel Sadra is waiting there. The Science Ninja Team ends up in the ruins facing an enemy robot in the form of a statue representing a deity, equipped with laser rays. It shoots at anything that moves.

.. and the team doesn't know what to do. But thanks to a bomb somebody installed in the robot statue it is destroyed, and the team sees Getz killed by a feather shuriken. They pursue a fleeing shadow which looks like Joe. But was it really Joe? Could he be alive? The shadow leads them to a secret Galactor base which uses the ruins of the shrine as camouflage. Galactor continues in its preparations to launch the missile. The Science Ninja Team wants to stop them and they get into their individual mechas The five of them start an all-out attack on the base. Because of the Ninja Team's attack, the Galactor operation ends in failure, but Ken's Eagle Sharp is wrapped in the explosion's flames and crashes in a forest. While losing consciousness, Ken faintly hears Joe's voice. When Ken regains consciousness, a man is standing before him. It's the former Galactor physician, Doctor Raphael. He tells them of his childhood, revealing his hate for Galactor. Then Jinpei notices that Raphael's shadow is similar to Joe's. Dr. Raphael tells them that it was him who saved them from Galactor.

Somebody sneaks into Galactor's Headquarters and a plan to build a huge base in San Frangeles is relayed to the Science Ninja Team. Ken and the others are baffled at the voice of the communication. It sounds exactly like Joe's. Elsewhere, Galactor has a corps of knights, clad in black armour made of a special Sigma lightray-strengthened steel, sneak in places to steal nuclear energy. The plan is to have them destroy the city of San Frangeles while the base is still being completed. The Black Knights are actually internationally wanted criminals. Since the Science Ninja Team has been told that the escapees have secretly built a town, they go to the ruins of the prison on Alamo Island by San Frangeles. Jinpei is given precise instructions by a voice that sounds like Joe's and the Ninja Team discovers an enemy base that is still being constructed on the bottom of the sea. They sneak into it and install a time bomb. However, they are captured by Gel Sadra. The Science Ninja Team dares to try the Tornado Fighter to escape. The base explodes and they end up floating on the sea, from where they are again rescued by a mysterious person.
