After venturing into outer space due to salvaging an alien ship which crashed on Earth, humanity formed the "United Universe". However, not all of humanity agreed with this organization, and a number of rogue planets stood opposed to them.
Eventually, a criminal and leader of the "Anti-United Universe" who goes by Xacalite, stole a battleship named Gloire and later stole planetary buster missiles. The United Universe's computer, YGGDRASIL, responded immediately to the problem by dispatching the prototype SA-08 Super Dogfighter, Silpheed, to attack and destroy Gloire.
