Wakusei Robo Dangard Ace

Synopsis

On Earth, natural resources are running out to the point that humans are thinking of moving to other planets to survive. Their eyes turn to Prometheus, the tenth planet in the solar system, with characteristics identical to those of Earth. A first space expedition takes place but is intentionally destroyed by Doppler, an upstart who wants to become master of Prometheus and destroys anyone who comes near his planet. All except the Danguard Ace, built in secret and protected by Captain Dan, a former officer of Doppler. Will this ship be enough to save humanity from Doppler's hostility?
