Shin Getter Robo vs. Neo Getter Robo

Years after the Reptilian Empire was defeated, the Getter Team has started training on a new super robot, Neo Getter Robo. But when the Empire's revived leader launches a surprise attack, they are forced to bring in a street fighter named Go Ichimonji to pilot Getter One. With an enormously powerful enemy before them, the new team's only hope for victory may rest on reviving humanity's lost weapon, Shin Getter Robo.
