SpaceGodzilla is a Godzilla clone kaiju that first appeared in Toho's 1994 film Godzilla vs. SpaceGodzilla.
SpaceGodzilla was created when Godzilla cells cast into space fell into a black hole and reemerged from a white hole, starting to assimilate crystalline organisms while rapidly evolving, the final result being SpaceGodzilla. How Godzilla's cells were cast into space is unknown, but there are two reasons stated in the film. Mothra may have brought his cells into space after her battle with Battra in Godzilla vs. Mothra. Another suggestion is that when Biollante's spores flew into space, some of her G-cells were responsible for the creation of the space demon.
After being born, the Combat Creature was sighted flying through space in his flying form as he destroyed a NASA satellite. The penguin mecha M.O.G.U.E.R.A. was deployed to attack him, but was ultimately defeated. He later set his sights on Birth Island, home of Godzilla and his son. He captured LittleGodzilla using his telekinetic crystals, forming a prison around the Godzillasaurus cub. He left the island and set up his crystal fortress in Fukuoka, but M.O.G.U.E.R.A. tried to stop him.
SpaceGodzilla overpowered the giant robotic penguin until he teamed up with Godzilla and split into two parts, Land Moguera and the Star Falcon. Land Moguera went for the foundation of his fortress as the King of the Monsters razed the Fukuoka Tower, knowing it was the source if his cosmic clone's power. Godzilla and MOGUERA fought SpaceGodzilla, with M.O.G.U.E.R.A. blasting the heinous space monster's shoulder crystals, critically weakening him. In pain and anger, SpaceGodzilla destroyed M.O.G.U.E.R.A., but not before the punisher penguin knocked him down. His opponent down for the count, Godzilla used his red spiral heat ray several times at his foe, as SpaceGodzilla slowly died. Like Biollante, he exploded into spores and was finally destroyed.
