Shin Getter Robo vs. Neo Getter Robo

Years after the Reptilian Empire was defeated, the Getter Team starts training with a new super robot, the Neo Getter Robo. But when the Empire's leader suddenly returns and launches a surprise attack, they're forced to bring in a street fighter named Go Ichimonji to pilot Getter One. With their enemy stronger than ever, the team's last chance might be reviving humanity's lost weapon-the Shin Getter Robo.
