The Modified War

For Many years, a creature that can adapt very fast and has many other subspecies under its belt has been at war with humans for centuries now. this war has destroyed most of the world as the creature has been able to disguise itself as a human, giving it a way to pass as a human in the world. which usually results in the creature revealing itself to the masses and also resulting in pure chaos and absolute destruction for the rest of the world. the Government has been trying to find ways to eradicate the beast from this world to prevent even more destruction to happen, but none of their attempts of killing the beast have worked in the slightest. So the world has had to suffer from the government's battle between the humans and the beast for many decades.
