Just outside the Earth's solar system, the Argo receives a distress call from nearby Planet Brumas. Derek Wildstar recognizes the planes attacking the planet as the same ones that flew over Earth during the blackout. The Argo attacks the planes in ou... (more)ter space while Space Marines stationed on the planet make their stand. After defeating the enemy planes, Wildstar sends the Argo's Astro Fighters to the surface, where they destroy the enemy tanks and take the Space Marines on board. Sandor analyzes the tank remnants and verifies that the metal alloy comprising them isn't that of Earth or Gamilon, thus Earth is facing a new enemy. Wildstar reports this to the Earth Defense Force commander, who pardons the Star Force and places them under his command.
