Heroes Uprising

It first appeared on the coast of Mindanao, Philippines. An unknown species we can call it. Everyone thought it was harmless as a sheep. But then, it accidentally tasted the flesh of a human. After that, things started to go haywire, it multiplied as it feast on human flesh, no one can stop, nothing can. Bullets bounce off of its skin, tank shell or any kind of explosive are ineffective. Even trying to poison it didn't work. The Philippine Government was on it's last straw. That's why they choose to abandon everyone on Mindanao and containing said creatures on Mindanao region. But who would've thought that they were smarter than it actually looks? No one. They started to adapt, think, and most of all, communicate with each other. They evolved too fast for humanity to follow. They grew extra limbs, gills, fins, wings, and even human functions. They waited patiently on Mindanao, evolving, scheming, and most of all, building it's lair. After year 2035, they attacked out of nowhere, from the sky, from the sea, under the ground. They came out of nowhere, striking every military force or bases on every corner of the world. But, that attack, which earned their name as Deviano, was a blessing in disguise for the whole humanity. Humanity on it's last legs discovered a whole new element. An element which they called Cord Particle. An element in which the Devianos greatly hate. An element which gave hope to humanity. They experimented on it, from using it for bullets, to actually injecting it to humans themselves. Hence, the warriors humanities last hope were called. Cordials, the last defence and last offence of humanity to survive against Deviano alike.
