Gatchaman

After Leader X is seemingly destroyed for good at the end of Gatchaman II, a fragment of him that survived grows and mutates into Z. With the head of the Egobossler family, Count Egobossler (and his two subordinates Mechandol and Kempler), Z is bent on destroying the Earth, and the Science Ninja Team, once more. In the wake of Anderson's death, Dr.Nambu has become the new head of the ISO, while the team is now confined to the Gallatown (aka "G-Town") underwater base. Engineer Kamo is introduced, and after the New GodPhoenix is destroyed early on, the team receives the new Gatchaspartan as their mecha. The Gatchaspartan has a special mode as well, called Hypershoot, that can only be utilized by Ken (with his new "Gatchafencer" sword). As the series progresses, it is learned that the radiation exposure from constant use of the Hypershoot is slowly killing Ken, and that continued use would mean death. Meanwhile, Z plans to destroy the earth with an antimatter asteroid, codenamed "Poison Apple".

A.D. 2066 - Shortly after a small country separates itself from the United Nations, members of the International Science Organization mysteriously disappear without a trace. Renowned scientist Kouzaburou Nanbu realizes that the secret organization known as the "Gallactor" is making its move to conquer the world. To counter this terrorist group, he prepares his ultimate weapon: five brave heroes that comprise the Science Ninja Team - Gatchaman.

This is the condensed theatrical adaptation of the original TV series' first season. The sinister mutant Berg Katse has launched armies of henchmen and giant weapons of mass destruction against Earth. But the forces of evil are about to meet their match! The Science Ninja Team stands ready to take the battle back to the bad guys.

Two years after the defeat of Galactor and the apparent death of Condor Joe, a cruise ship is attacked by Leader X, killing nearly everyone on board. One of the survivors, a young girl, is captured by X and rapidly aged into the bizarre, masculine-voiced villainess Gel Sadra. Though she has the appearance of an adult, Gel Sadra is not immune to throwing childish tantrums and behaving immaturely. In the midst of the revival of Galactor, the Science Ninja Team is called back into action, with a shady man known as Hawk Getz acting as the replacement for Joe. Getz is quickly revealed to be a Galactor agent in disguise (and had killed the actual Getz who was to join), and winds up killed by a mysterious feather shuriken. After hints spread in the first three episodes, Joe reappears in the fourth episode, having somehow survived his fatal injuries at the end of the first series, and rejoins the team. It is later revealed that he was rescued by an ex-Galactor scientist at the brink of his death, and was the subject of various cybernetic augmentations. Later in the series, a female scientist known as Dr.Pandora is introduced, who had lost her husband and daughter in the cruise ship disaster. Unbeknown to her, her daughter Sammie survived and is in fact Gel Sadra.
