In the future, earth is attacked by Galactor with a series of mechanical menaces. Each with their own vehicle and unique weapons, only Gatchaman's high tech group of five young people can defend the earth from Galactor's repeated attacks as they attempt of fulfill their mission to find Galactor's hidden headquarters and finally defeat Galactor. Gatchaman originated the concept of teams of 5 members, with their own vehicles, which has been reused in many incarnations, including the ranger series (which came over to the US as Power Rangers). Gatchman spawned two sequel series: Gatchaman II and Gatchaman Fighter. Gatchaman was brought to US audiences in a heavily edited form known as Battle of the Planets Battle of the Planets and later as G-Force.

From the cellar of a bowling alley, the "Mecha Ball" appears and starts to destroy the city. Because of the Mecha Ball's simple structure, an attack is futile since there is no weak point. Opposing his four eager teammates, Ken decides not to go out, saying that if they attack without a chance for winning, they will only die a useless death. At the same time, Ken watches Jinpei move a pachinko ball with a magnet and gets an idea how to defeat the mecha. When Nambu hears Ken's proposal, he immediately builds a huge electrical magnet in the middle of the alps and decides that the God Phoenix must lure the mecha there.
Scientists from the ISO headquarters are murdered one after the other and Nambu orders the Science Ninja Team to act as bodyguards. The Science Ninja Team separate for their guard duty. During Ken's guard, he surprisingly meets Galactor's Ninja Blackbirds and follows them, but loses sight of them near an amusement park. At the same time, Jun and Jinpei are attacked by a Neon Giant which appeared accompanied by the sounds of a flute. In order to let the scientist escape, they offer themselves as bait, but fall off the street. Jun reports that the Neon Giant resembles the Indian statue standing before the amusement park where the Black Birds vanished. Because of that, the Science Ninja Team waits for the night and sneaks into the park to start investigating.
An ISO volcanic research center is attacked. The God Phoenix, starting the investigation, is surprised by the Magma Giant and escapes into the sea where the Giant cannot follow it. When Joe says that the Magma Giant's face resembles the face of Jesus Christ sculptured into a steep slope in the national park, the Science Ninja Team goes there to investigate. A girl climbing the Jesus Christ sculpture is suspected to be a Galactor agent by Joe and questioned, but she answers that she's here to sculpture the statue, continuing the tradition of her family in the third generation. Together with the girl they go into the cave found in the steep slope and discover a base. The Jesus Christ face sculpted in the slope, is plunged into lava seething in the interior of the base and comes out as the Magma Giant. Seeing this, Ken calls the God Phoenix. At the top of the base, there's a special glas which is actually at the bottom of a sea. The sea is used as a lense to heat the magma, using the sunlight. With a rocket, they break the glas and thus destroy the base. When a message comes in from Nambu that the Magma Giant is heading towards a city, the Science Ninja Team split up in their individual machines and lure the Magma Giant towards the sea. The Magma Giant cannot resist and steps into the sea. Through the sea water he's instantly cooled and becomes a black piece of rock, standing still. The girl then gets her chisel to begin sculpting again.
ISO ships are attacked one after the other by Galactor's black ray. And because Ryu is napping in the God Phoenix, he cannot be mobilized.

During this time the fishing areas in the village become polluted through unknown causes. Since Ryu's father is the co-operative head, is blamed by the village people.

When Lucy tries to answer, she suddenly starts to move strangely and finally breaks through a wall and falls to the ground where she explodes. She was a cyborg manufactured by Galactor, and a radio signal emitted by X caused her to self destruct. Joe is taken aback by Lucy who is now nothing more than a pile of iron fragments. His anger towards Galactor is ignited again.

Egobossler's first attack, backed up by one of Zed's giant mechs, completely startles out heroes. Ken, Jun, Jinpei and Ryu rush to the scene of the battle (leaving Joe behind to quietly expire). The mech is too powerful, and the New Godphoenix is completely trashed in the first skirmish with Egobossler. Fortunately, Chief Engineer Saburo Kamo is waiting in the wings with brand new mechs.
