Getter Robo

A group of mechanical dinosaurs emerge from beneath the Earth's surface, aiming to destroy humanity and take over the planet. Following the destruction of a prototype Getter Robo by one of these machines, the Saotome Research Institute activates a fully operational version. With a shortage of pilots, Ryo Nagare recruits Musashi Tomoe, a martial artist, and Hayato Jin, an outcast, from his college to join him in piloting the Getter Machines against the threat.
