Seasons & episodes

Joe has sneaked alone into a Galactor base, searching for Governor X. A mysterious girl named Cathy appears before him and tells him that Governor X has moved to the volcano Vesuvio. X has indeed moved to a base in the interior of that volcano, a base built by Berg Katse. X gets angry at a town built by people who are using the volcano's energy. He plans to destroy the city with missiles that will destroy the earth's crust. Magma streams into the subway system of the city. Elsewhere, Nambu who is the architects of the city, has a missile installed in the God Phoenix. This missile will solidify magma. He does this in order to save the city. However, they meet resistance from the enemy and the missile is wrecked. Joe intends to activate the magma solidifying device himself by throwing himself into the magma and pressing the switch. Cathy is a cyborg like Joe, and she has fallen in love with him.

A mysterious UFO flies over cities and mountainous regions all over the world. Additionally, airplane passengers who vanished half a year ago appear again, without memory. Because the spaceship has come to request to talk with humankind, the Science Ninja Team undertakes the task on a remote island in the South Sea. The person who exits the space craft is the famous Earth Defense Force pilot Major Borg, who was believed to be dead, killed in combat against Galactor. He says that when he was saved by that spaceship, Kentaro Washio was alive inside that ship. When Ken learns that his father, who sacrificed himself to save the Earth, is alive, he sways. He takes off in the G-1, following the UFO which took off after Borg exited. He sees his father through a window, but then crashes against a wall. Borg saves him and, led by Borg, Ken leaves in order to meet his father. Borg's son has been taken hostage by Galactor and Borg has been forced to set a trap for Ken.

Galactor's cruise missile crashes and explodes in a fishing village. Its inhabitants have disappeared. Ryu is sent to investigate and saves a girl named Yuka who is pursued by the villagers because they suspect her of arson. Yuka feels love at first sight for Ken, whom she meets because of the investigation. She tries to ensnare him. However, Ken is cold towards her, he does not understand such feelings. Elsewhere, Ryu has fallen in love with Yuka. He has watched everything and tries to comfort her. When she says that she lost a finger ring and that it fell into the sea, Ryu with his pure heart believes her immediately and jumps into the sea in order to search for it. He finds a pearl, and by coincidence, he also finds the cruise missile's memory chip that has sunk at the bottom of the sea. Ryu gives Yuka the pearl and hurries towards his comrades with the memory chip. In the analysis it results that the target of the missile was an observatory.

A Galactor traitor steals a secret micro file from a base and gets it to the ISO headquarters. In order to decode the file, Joe goes to the Ongurei Research Institute where they have some special decoding equipment. But there's an electronic transmitter attached to the file. Its signal is detected by Galactor and they proceed to attack Joe. Saved from the critical situation by Ken and the others, Joe hurries towards the research institute again. But a strong headache attacks him. He is blinded and falls towards a valley. "What's happening, this is not supposed to be happening to my body again" he thinks. While losing consciousness, Joe remembers his past, when he found out that his father was a Galactor member, when he died as a result from an old wound he got in his head, and when he was resurrected as a cyborg. Joe is saved by Jun and regains consciousness. The file is safe.

An experimental city named Seatoland that swims in the ocean, has been built by the ISO. It is attacked by a Galactor monster called Umiba, and faces total destruction. When this message is received, the Science Ninja Team is mobilized, but Dr. Siski, in charge of Seatoland, refuses to collaborate with them. Milly, the doctor's daughter, has been taken hostage by Galactor during the attack. The doctor himself has been intimidated and forced to collaborate with Galactor. The doctor finally tells Gel Sadra the equation which increases energy and allows the extremely powerful magnetic fields to be used. The doctor is then ordered to lure the Science Ninja Team into their deep sea base. Jun has overheard this by coincidence and knows now that her friend from childhood, Milly, is still alive and has become a Galactor hostage. Jun keeps these dangerous news away from Ken and the others. She sneaks into the deep sea base in the Marihole, together with the doctor.

A spaceship is being repaired by Jun. Jinpei releases a safety button because he is threatened by a gun, causing the spaceship to take off. The robot threatening Jinpei turns out to be a girl who introduces herself as Sachiko. Sachiko wants to meet her father, Tetsutaro Arimura, who works as research head at the Earth Investigation Station Moa. Following her wish, the ship makes a forced landing at the space station. But no one is there. While searching for Arimura, they coincidentally run into Galactor and get into a difficult situation. Galactor's goal is to steal data tapes of the Mantle energy and occupy the station. Using the two as hostages, they rob the Mantle energy data from Arimura. But the Science Ninja Team quickly arrives to rescue Jinpei and forces Galactor to retreat by shooting the artificial gravity device.

Communication with police and military forces in the highland of Oshia keeps getting cut off. Joe has been behaving strangle as of late, and as Ryu follows him, he disappears in that same spot. Ryu leaves behind the words "spiral galaxy!?". The Science Ninja Team thinks that all this is the deed of Galactor and starts an investigation in the Oshia region immediately. There, Governor X's new weapon, Galamoeba, is hidden and waiting. The Science Ninja Team tries to resist with the God Phoenix, but they are hauled inside the enemy mecha. There they are released into another dimension. The humans who disappeared were also in that other dimension. They had been brainwashed in order to become soldiers to build the solar shift plan. The Science Ninja Team is sentenced by Gel Sadra to vanish with the other dimension in twenty minutes. Ryu is floating around in this dimension and Joe rescues him with his car.

Tojo island, in the country Rizoto, sinks into the sea because of mysterious movements in the Earth's crust. Jun has gone to investigate the small islands in the vicinity and goes into a cave on one island. There she falls into a trap of a Galactor spy disguised as a survivor. The spy then disguises herself as Jun and penetrates G-Town. In the engineering room she installs a cloaking device. G-Town is being led towards a Galactor trap on the bottom of the sea. In reality, the spy is Eva, the daughter of Bill Douglas, who has developed the machinery of G-Town. She is being used by Galactor who told her the lie that her father was killed by the Science Ninja Team. Elsewhere, Jun has escaped from the enemy's prison. She attended the death of Bill Douglas there who was severely tortured. Jun goes back to G-Town and tells Eva what actually happened. Jun gives her a keepsake from her father.

Ken goes to the luxurious residence of his old friend Karl III, with whom he had lost contact. Karl is the successor to the leadership of a group of 300 enterprises in the whole world and is now organizing a meeting of the former pupils of the flying school which he and Ken attended. But Ken's heart is heavy because he has a task to verify whether or not the rumour that Karl wants to build an empire and conquer the world is true. But the rumour is true as Ken finds out when he's searching the house, whereby Lisa catches him. Together they find a secret passageway and hear Karl speaking to his troops. Karl is also secretly collaborating with Galactor. He offered them the Mantle Power-up Plan in exchange for weapons. Ken and Lisa are detected though. Karl tells Ken the truth and then wants to execute him and his fiance, Lisa (who also attended the flying school together with Ken and Karl). In that moment Gel Sadra appears before Karl and points a gun at him.

People keep collapsing everywhere. 20,000 humans die of unknown causes. Since radioactivity has been detected at the same time, the Science Ninja Team starts searching for its source. While investigating, Jinpei and Ryu encounter three boys and go with them to the Negiris plateau. The boys love UFOs and wanted to try to establish a contact with the extraterrestrials. They say they caught some strange radio waves while doing so. Following its source, Jinpei, Ryu and the boys arrive at Stonehenge. At that moment, a solarshifter appears out of the Stonehenge stones and Jinpei and the boys are taken away. Ryu is left behind. He meets up with Ken and the others. They want to save Jinpei, but can't approach because of a strong barrier in form of a dome. Elsewhere, Jinpei has heard the whole secret of the base. He tricks Gel Sadra, taking advantage of her way of thinking, and escapes the holding cell, taking the solarshifter's programming chip with him.

Big movements of the Earth's crust occur at the North Pole. Immediately thereafter, the adventurer Shimomura leaves Greenland on his way to the North Pole. He is reported missing on the third day of his voyage. By coincidence, he discovered a Galactor base and has been shot. When Ken learns that his teacher from school, Shimomura, is missing, he goes on a search mission to the North Pole together with the other members of the Science Ninja Team. However the God Phoenix cannot go all the way to the pole because of the influence of the magnetic field. During the search, Makku, Shimomura's beloved dog, has been discovered. He alone escaped the Galactor attack. Ken takes it with him and continues the search alone, not knowing that Shimomura is already dead. Makku leads Ken back to where Shimomura was shot. There, Ken also discovers the Galactor base. He tries to contact his teammates, but due to the magnetic field, he cannot get a connection.

Galactor releases test waves of the solarshifter. At the same time, in the city of Owari, accidents due to anomalities in the main computer keep happening, which provoke a panic. The Science Ninja Team goes to Owari in order to find out the reason for all this. But when they arrive in the city, Pimer and the New God Phoenix also cease to function properly. Galactor takes advantage of this opportunity and attacks with hang gliders. In order to return their attack, the Science Ninja Team leaves the God Phoenix, but Joe's condition is not good. Ryu returns to G-Town with the God Phoenix. Joe is not to be deterred though and starts his attack. However, the huge shield of electromagnetic waves around the solarshifter affect his cyborg body in a bad way. He gets into a critical situation and becomes unconscious. He is saved and treated by Dr. Raphael, who revives him. Even though Dr. Raphael warns Joe about the electromagnetic field, Joe does not want to let down his friends.

A spaceship from Earth is suddenly attacked by meteorites, and the Science Ninja Team hurries to the bottom of the sea, to the spot where the meteorites fell. But there, mysterious robots that arrived a bit earlier, are already collecting the meteorites. Is it Galactor...?? Joe follows the robots and corners them, but they are not Galactor. On the contrary, they greet him as "brother". They are cyborgs as well who have been made by Dr. Raphael. A cyborg who introduces himself as Ulf leads him to their colony. There he meets Ulf's comrades, who are equally friendly, as well as Dr. Raphael. Then he learns that they want to invite him to a strength experiment. Before Joe's eyes, many cyborgs die when they are tested under extremely hard conditions. Then Joe is called by Ken and has to return to G-Town. Elsewhere, Galactor has noticed the existence of Ulf and the others. Using the meteorite's guidance system, they let meteorites fall onto the colony and destroy it.

The Science Ninja Team departs to pick up Dr. Pandora, who is supposed to become Dr. Nambu's secretary. In order to remain inconspicuous, they put Dr. Pandora and her car in a truck and head towards G-Town. Suddenly, Dr. Pandora tells them to leave the road. Despite getting suspicious, the group leaves the road and heads into the desert. Because of this, a Galactor ambush has been unsuccessful, and they then start to attack with airborne troops. The truck is destroyed, but the team manages to escape after a fierce fight in Pandora's car, which has been equipped with weapons and has been made bulletproof. Finally, they reach G-Town. Nambu takes Dr. Pandora with him and together they leave for Cape Long to investigate an incident at a factory for gaining Mantle energy. Joe is suspicious because of the smile Pandora left behind and because he learned that she's an expert in cyborg technology.

The Science Ninja Team hurries to the hospital. When Dr. Pandora announces that she's giving the orders now, Joe tries to shoot her. Ken stops him. Because the person who shot Dr. Nambu is not known, Dr. Pandora then orders the team to investigate a certain spot from where specific brain waves are emanating. While the team is on its way there, they receive a message that Dr. Nambu has died. Joe still distrusts Dr. Pandora and returns to the hospital alone. The rest of the team wants to return too, but Ken tells them to obey Pandora's orders (and slaps Jun). They detect a Galactor base at their destination and sneak into it right away. Galactor has amplified Gel Sadra's special brain waves and has created a monster which is about to attack Dr. Nambu. Pandora has foreseen that and has put Dr. Nambu in a state of suspended animation (by shooting him), thus resisting the monster's brain wave radar.

In the city, Joe is attacked by a female biker. She says "ask the feather shuriken, why this happened" and escapes. Later, upon Dr. Nambu's order, Joe moves out with his comrades to investigate the defeat of the secret tank forces of the international defense army. But in the middle of the investigation, the woman appears in front of Joe again. She is Mako, the fiancee of Hawkgetz, who was supposed to become G-2. Mako firmly believes that Joe killed Getz because Galactor has told her so. She misunderstood that Joe has killed an imposter posing as Getz. Galactor had actually killed Getz. Joe tells Mako what really happened. He gives her a pendant that he got from the real Getz, just before his death, with instructions to hand it over to Mako. Then Joe leaves to bury the Galactor subordinate who used Mako as a means to assassinate him. Meanwhile, the rest of the team has taken care of the underground Galactor fortress. Jinpei was shot down, but not hurt.

Galactor has built a base on the mountain K3 which is located in the Himalayas. From there, a magma mega cannon shoots through the Earth and attacks cities all over the world. The only way to penetrate the base is through the North Wall, which is impossible to climb however, because it's 3,000 meters high and vertical. Suffering under the fact that he has a cyborg body, Joe is about to despair, and takes over this dangerous task when Nambu orders it. Ken is not happy about this, the Science Ninja Team has always been a team after all! That Joe is a cyborg and can handle things on his own is no reason to send him alone. Joe however coldly refuses when Ken and the others offer to accompany him. Jun follows Joe and he finally accepts her company. But because of Jun's carelessness, Galactor notices them and the two of them are swallowed by an artificial avalanche. Additionally, they can't move because of the cold. They are surrounded by the enemy, and don't know what to do anymore.

Because his father is hurt, Ryu gets into the Horned Tank and goes back to his native fishing-village. However, in the sea around the village, Galactor plans to destroy a gas chamber and let the land sink into the sea. When Gel Sadra sees the G-5 heading towards the village, she thinks that the Science Ninja Team got wind of her plan. Ryu has indeed noticed some strange bubbles and Nambu tells him that he will send the God Phoenix to investigate. Gel Sadra charges two assassins with infiltrating the village and aiming at Ryu. Opposing the attacking Galactor, Ryu pretends to be weak and gets out of the difficult situation because the assassins start to doubt whether he really is a member of the Science Ninja Team. However, shortly thereafter, his father and younger brother are abducted by Galactor. Ryu follows them and finds out that a petroleum tanker at sea is actually the Galactor base. In order to save his family, Ryu sneaks into the base.

In G-Town, the G-1 has been altered in order to reduce its mach resistance and enter the atmosphere more smoothly. Ken boards the G-1 immediately and goes out on a test flight. But he enjoys the flight so much that he doesn't pay enough attention and is shot down when he accidentally gets near a secret Galactor base. Ken somehow manages to make a forced landing, but his bracelet is damaged and he can neither establish a connection nor transform. Furthermore, he is also hurt. Fortunately, a native boy, Peter, saves him. Peter and his older sister tend to Ken's wounds and hide him in an old barn. Ken attaches a transmitter to a carrier pigeon he finds there and lets it fly into the sky. Elsewhere, Peter and his older sister are captured by Galactor members and end up tied to a tree. Joe and the others have caught Ken's radio signal and come in a hurry. They save Peter and his sister just in time.

The information arrives that there's a secret Galactor base in the Andes. Ken and Ryu go to the Andes in disguise in order to contact the intelligence member Yupanki. However, Galactor makes them drink some medicine, whereupon they lose their memory, forgetting their task and their names. The wandering Ken meets a dying man who says he has been hired by another man named Yupanki. The man entrusts him with a silver coin, as Yupanki told him to do. Without remembering Yupanki's name, Ken follows the man's last will and gives the coin to the man's daughter Kena. As it is, Ken decides to settle in that Indian village, living together with Kena, and falling in love with her. Meanwhile, Joe and the others discover Ryu who also lost his memory, and find out what antidote would help. Ken is at the same time fortunately stung by an Inca-Scorpion. Its poison is the aforementioned antidote and it negates the effect of the medicin. Ken regains his memory.

A big earthquake suddenly happens in New Joke. But the inhabitants are not the only ones who are shocked - so is Gel Sadra. She never gave this order! This operation has been undertaken by the Galactor commander Panther. He convinces Gel Sadra to participate in the operation, thus showing Governor X her strength. The Science Ninja Team goes to investigate and detects a missile base in a huge underground, public hall. Galactor has shot a missile into a gas chamber and thus created the earthquake. At that moment, the missile that Joe, Jun and Ryu discovered is launched, causing another earthquake. It also causes the hall to collapse and Joe, Jun and Jinpei are locked in. Under Nambu's order, Ken and Jinpei leave for Rodo Island to stop the guidance waves of the missiles, even if they don't like leaving their comrades behind. But the attacked Galactor base rises into the sky! The base is the huge mecha Mechasatan.

In a Galactor base at an upper course of the Amazon, a new weapon using Hypertonium is produced. The base is protected by the mechanical plants which surround it and push back any invader. Jinpei is investigating the area around the river when somebody attacks him and shoots him down. He is saved from the piranhas in the river by some local children. The team rejoins him and brings back the Helicopter and the bracelet Jinpei lost during his escape. Jinpei is ordered to remain on standby while the team searches the Amazonas. However, Jinpei somehow ends up in the difficult situation of going with the children into the interior of the Amazonas in order to pick up a legendary, blooming blue orchid. They detect Galactor troops, secretly follow them, and discover a Hypertonium transport vessel. However, Jinpei and the children are discovered and captured.

Joe saves the son of Kaiser from an approaching car and becomes his friend. Together they play soccer while Kaiser draws Joe. But Kaiser is a former Galactor member and the only one who can handle a weapon Berg Katse has left behind. It's a weapon called Mechavolton which was built to destroy the greatest obstacle for Galactor's highflying ambitions, the Firebird. Kaiser, a.k.a. No. A-7, was thought to have died in the battle of Cross Karakorum and has led a peaceful life since then. But when Galactor threatens to kill his wife and son, he works together with them again. As a diversion, the Iron Bat attacks a city. The God Phoenix goes out to attack the Bat, but is wrapped in ice through a freezer gas. With the help of the Firebird they escape from the predicament for a short while and destroy the Iron Bat, but when Kaiser fires the Mechavolton, they are finally shot down. The Science Ninja Team escapes by a hair's breadth and invades the enemy base. But Kaiser blocks their way.

In an underground ISO city in Siberia that uses mantel energy, a huge explosion takes place which results in a high level of radioactivity. Causing this has been Megatonra, a monster which has been brought from space by Governor X and which grows by absorbing radioactivity. Megatonra has been put under the Earth by Gel Sadra where it has been eating radioactive waste and has grown considerably. Then it has started to destroy the underground city. Dr. Horin is the husband of Mary, the architect of the city, that died in an accident. Ken goes with him to investigate the underground city. But Mark, the son of Dr. Horin, has secretly sneaked in the expedition car. Mark hates the underground city because it took away his mother and he intends to destroy it. The monster appears and destroys the Mark Park, which Mary left behind for her son. When Mark sees this, he flies away in the expedition car in order to protect the underground city constructed by his mother.
