Getter Robo Arc

From deep within the Earth's surface, the Dinosaur Kingdom make their move to wipe out mankind and conquer the planet with their mechanical dinosaurs. After a prototype Getter Robo is shot down by a mechanical dinosaur, the Saotome Research Institute decides to use the real Getter Robo, which is combat-capable. Due to a lack of pilots in the institute, Ryo Nagare goes to his college to persuade martial artist Musashi Tomoe and outcast Hayato Jin to join him and pilot the Getter Machines to combat the new threat and protect mankind.

Takes place after the final defeat of the Dinosaur Empire and the death of Musashi Tomoe in the original Getter Robo series. Dr. Saotome, creator of Getter Robo, fears that the peace the Getter Robo team has won will be short lived and that an even greater enemies would appear. Dr. Saotome's fears are justified when the militaristic Hyakki (or "Hundred demons") Empire appears, but Dr. Saotome is prepared with the creation of an even more powerful Getter Robo, Getter Robo G and a new Getter Robo base. Also with Musashi Tomoe dead, Dr. Saotome needs a third pilot which he finds in baseball player Benkei Kuruma.

Humanity is under attack by demonic creatures called Oni. Unable to fight back by any other means, the scientist Dr. Saotome creates a series of giant robots that harness the mysterious power of Getter Rays, giving them the strength necessary to fight the Oni. The strongest of these is Getter Robo, and Saotome must enlist three very different men to pilot it - martial artist Ryoma Nagare, criminal leader Hayato Jin, and monk Benkei Musashibou. Together, the Getter Team fights to end the Oni menace forever.

Sent to jail after being accused of murdering Getter Robo creator Dr. Saotome, Ryoma Nagare must once again team up with his former comrades and pilot Getter Robo when Saotome returns from the dead and threatens humanity by unleashing his greatest creation - the Shin Dragon. Their efforts, however, are in vain as they fail to stop a nuclear warhead from hitting Shin Dragon, resulting in a massive Getter Ray contamination that wipes out 99% of the planet's population. Thirteen years after this great catastrophe, mankind continues to fight for survival against the Invaders. Out of the remains of the nuclear blast comes Shin Getter, piloted by the artificial human Go. With remnants of the Japanese military by his side, Go - along with co-pilots Kei and Gai - must use Shin Getter to exterminate the Invaders once and for all.
