Hi @Belle, the following is a set up I'm thinking of a survival island 1x1 story. I'm thinking of something along the lines of a [b]DR. Monrow Island[/b]. 
I am an escapee from the asylum where I was being used in experiments, being given various drugs, swapping body parts with various animals (my face has been extremely altered, looking more primate than human at this point.)  One night after given a dark looking substance I gained a surge of adrenalin and bashed my way into the surrounding jungle. 
As I wake I find myself at the sore with the latest supply boat. You are the only one left, sleeping among dead bodies and open chains of the strongest left to fend themselves out among the island's darkest creatures. 
You wake when you hear the snap of the rock breaking your chains. The tear in my misshapen eyI'msays im looking for a friend, not food.

Thanks for reading. It is just a setup idea and if you like to alter it to something more to your liking I am eager to hear.
