---------------------------------------------------------------------------------------------------------------
After butchering and consuming everyone in that underground laboratory and escaping under the guise of a human, you went into hiding in society. Switching between appearances to stay hidden along with eating people that no one would miss, especially criminals. You'd sometimes eat some grimm too.

What happened to you is that you were born as a bizarre pile of biomass created by nature's natural selection. When some humans made contact with you years later, you immediately infected and possessed one of them and began to evolve rapidly. It was then you developed a personality and can think like an intelligent species. All before being captured, experimented on, and then escaping not long after.

Luckily for the world, you aren't super bloodthirsty or a complete psychopath. Your personality is that of someone humble and wanting peace. Just like how mother nature is and must be respected as so.

Speaking of the world, you figure out that the world you reside in now is called Remnant. Compared to the laboratory below, the outside world is much worse with the Grimm and humans fighting each other.

But it is also the world where you will actually find your place in these harsh lands of savage beasts and advanced weaponry. Along with those whom you will reside alongside with. And if anyone wishes to take them from you, they will know the color of death from within.

You are the monster.

You are the parasite.

You are...

Carrion

This is your story.
