Shin Getter Robo vs Neo Getter Robo

Years after the Reptilian Empire's defeat, Getter Team has begun training on a new super-robot, Neo Getter Robo. But a surprise attack from the Empire's revived leader forces them to recruit a street fighter named Go Ichimonji as Getter One's pilot. Faced with an enormously powerful foe, the new team's only hope for victory may lie in the resurrection of Shin Getter Robo, the lost weapon of humanity.
