Ten years ago, an unknown alien race appeared in our atmosphere. Several goverments tried to make contact with their enormous ships via several means, but none of them were answered. Few days after their arrival, a new kaiju called Kamoebas appeared in Osaka, however it was stopped and put down by the Anti-Kaiju division of the JSDF before any considerable damage could be done. Another kaiju, named Ebirah, appeared off the coast of New Mexico but it was quickly slain by Godzilla himself.
It was soon revealed that the aliens sent those kaiju, not expecting the Earth to be prepared for them and having kaiju of their own. Because of this, the Niir'Lak Empire, as they called themselves, declared war on Earth. Their conventional army was launched to the Earth with walkers, hovercraft and blasters that looked straight out of a sci-fi film. However, the most worrysome part of their arsenal were their kaiju, almost all of them known foes of Godzilla and the Earth itself. Gigan, King Ghidorah and Orga were among them and they wanted revenge. At first it was thought they were being mind controlled but no, their actions were voluntary.
Humanity held off the attacks with the help of Earth kaiju and the use of some mechas. However, tragedy fell upon us. Two new hostile kaiju appeared in New York, one of them looked like the Devil himself, while the other looked like a less refined version of Kiryu. The new monsters were dubbed "Mechagodzilla" and "Destoroyah", and soon the Niir'Lak revealed the origin of Destoroyah. They had discovered prehistoric organisms on Tokyo Bay, one of the places they had conquered, and soon realized they were mutated by the Oxygen Destroyer used in 1954 against the first Godzilla and they were forming a new superorganism. They took them and made the beast obey them since its first stages, essentially creating a living superweapon.
Kiryu was dispatched to intercept them and Godzilla soon appeared to fight them. At first it seemed like the Earth pair was winning, but Mechagodzilla unleashed its true power and overwhelmed Kiryu, devastating half of Manhattan in the process. Even then, the hardest blow happened when Destoroyah evolved from his land form to his final form. Godzilla barely held his ground and was forced to use his spiral breath several times. By the end of the fight, Destoroyah fired a powerful energy beam from his chest, which collided with Godzilla's spiral breath causing an explosion the completely leveled New York. After the explosion, the only thing left was Destoroyah's limbless body and no sign of Godzilla whatsoever.
After that, the invaders started to conquer more and more terrain, defeating most human opposition and either killing or brainwashing most kaiju they found. Barely a year after the Battle of New York, humanity was defeated, our countries were turned into exploitation colonies or protectorates. The most powerful Earth kaiju like Mothra, Rodan and Anguirus have disappeared, and every supposed sighting of Godzilla has been confirmed to be just Zilla. However, Gezora's corpse has recently appeared on Queensland's coast, sparking a small bit of hope...
Here's my first story on this site! The story will be told from both the kaiju and the humans' perspective. Hope you like it, and please leave any review or comment you want, I'd really appreciate it :)
