On the anime Robotech, sometimes known as Macross, the Super Dimensional Fortress-1 warship crashed to Earth, holding the last known remaining supply of Protoculture. This brought the evil Zentradi to Earth. The Robotech Defense Force was assembled as part of the United Earth Forces to defend the planet against the humanoid giants.
