Getter Robo Arc

The fifth entry in the Getter Robo series follows events several years after Getter Robo Go, set in a post-apocalyptic Earth. Hayato, now an older scientist, finishes developing Getter Robo Ω, originally designed by Professor Saotome. The robot is piloted by Takuma, son of Ryoma, Kamui, a human-dinosaur, and Baku, the younger sibling of Tayel. They join forces with the reformed Dinosaur Empire to combat the Andromeda Flow Country, an insectoid force invading from beyond time and space.
