Ten years after the disappearance of Ryoma Nagare, Go Ichimonji and Messiah Tyr on Mars, the Saotome Institute is now under the command of Hayato Jin to train new pilots for protecting Earth against extraterrestrial threats both from within and beyond the planet. Of these individuals were Takuma Nagare, Ryoma's son; Sho Kamui, a human-dinosaur hybrid; and Baku Yamagishi, Messiah Tyr's younger brother. In the wake of the invasions between the remnants of the Dinosaur Empire and the swarm of technorganic insect-like aliens from the Andromeda Flow Country, the new Getter Team must work together to defeat both looming threats and using the new machine by the Saotome Institute: The Getter Robo Arc in order to protect humanity from its own extinction.
