The Battle of the Rainbow Galaxy
The Star Force has arrived at the Rainbow Galaxy nebula. General Lysis's task force begins its attack by deploying fighter planes to lure the Star Force's Black Tiger squadron away from the Argo. The plan works, and once the squadron is away, the Gamilons launch precision bombers, and use SMITE to teleport them into close range of the Star Force. The attack cripples the Argo's radar. The Black Tigers are recalled, and drive off the bombers, but not before the Argo suffers significant damage. Not relenting, Lysis next sends torpedo planes, warping them to the opposite side of the Argo. They inflict severe damage to the ship before being driven off, and nearly all of the Argo's gun turrets are destroyed. The Black Tigers then return to the ship for refuelling.

The Drill Missile flies backward, right into the Gamilon fleet, striking the very battle carrier from whence it came. The debris from the exploding ship strikes the other three carriers, wiping them all out. Only Lysis's command ship remains. Stunned at this turn of events, Lysis attempts to ram the Argo, chasing the Star Force into the black gas cloud. With the Star Force unable to see his ship, Lysis maneuvers beneath the Argo and grapples onto the lower hull. He contacts the Star Force by video to inform them that the battle is now over -- he has placed a bomb against their hull. Captain Avatar tries to convince Lysis that th

Star Blazers: The Quest for Iscandar
In the distant future, the war between the human race and the Gamilon has taken its toll on the planet Earth. Constant bombardment of radioactive asteroids has rendered the planet's atmosphere uninhabitable. As a means of relief aid, Queen Starsha of the planet Iscandar offers the Earth Forces a device that can completely neutalize the radiation off the planet. For this task, the space battleship Yamato is launched from the remains of its World War II ancestor on a 148,000 light-year journey. However, the crew of the Yamato has only one Earth year to travel to Iscandar and back, or the human race will come to an end.
