The Battle of Gamilon
Trapped between depth charge bombardment and the sulphuric acid seas of Gamilon, the Star Force desperately tries to find a way out. At his command centre, a building suspended from the ceiling of Gamilon's upper shelf, Leader Desslok monitors the battle's progress. He lashes out at General Krypt's offer to relax and have a drink. On the Argo, out of ideas, Wildstar seeks advice from Captain Avatar who suggests that they actually submerge the ship for 10 minutes in the acid sea, and seek out a volcano to disrupt using the Wave Motion Gun. After a few minor pieces of the ship have fallen off, IQ-9 spots the desired volcano. One hit from the Wave Motion Gun sends Gamilon into seismic upheaval. Desslok momentarily loses his sanity, exploding into a fit of uncontrollable hysteria. The Star Force ascends from the Gamilon sea. Leader Desslok orders the ceiling missiles above the central Gamilon city to be dropped upon the Argo. His aide, General Krypt, wigs out at this suggestion, knowing that it will destroy the city as well, and begs Desslok to end the battle and seek a truce. This earns Krypt a snide comment from the Leader (though in the Japanese version, it's a shot in the chest). Missile fire rains down on the Star Force, and so Wildstar orders the Argo to fly directly above the central city in hopes of discouraging further attacks. But this does not dissuade the Gamilons, and ceiling missiles drop like stones, wrecking the city and causing further volcanic eruptions. Gamilon's tectonic structure becomes unstable, and huge sections of the upper shelf collapse and fall upon the cities below. A shot from the Argo'smain guns strikes Desslok's command centre, which plummets to the ground below. Desslok himself is covered in rubble, but falls through a trap door, his fate uncertain. Gamilon falls still and silent. Wildstar finds Nova weeping on the main gun deck, and declares that he believes that this was their last battle. The Argo, badly damaged, lifts off. As C

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.
