Synopsis
The world is plunged into chaos when the supposedly dead Dr. Saotome resurfaces, wielding a terrifying new weapon called the Shin Dragon.
His sudden return forces Ryoma, a pilot with a complicated past with Saotome, to reunite with his old comrades, Hayato and Mushashi.
Together, they must pilot the Getter Robo to stand against Saotome's destructive ambitions and protect humanity.
However, their mission is complicated by the emergence of the Invaders, a mysterious alien force capable of possessing people and turning them into monstrous beings, adding another layer of threat to the already dire situation.
