My Parasite and Me

You have two beings in your head, you and a parasite that needs a host for survival. However it's not all bad since you and your passenger can work together now. The parasites steal skin can sprout from your body on your command and the parasites command. This skin is tough as metal and can work as a shield, sword, axe, or spikes to give your enemies a prickly surprise. You may make your parasite vocal or only internally able to communicate, if vocal though you both talk through the same mouth, your human mouth.

This newfound partnership comes at a price of never being fully alone and the much needed consumption of meat, or fresh flesh.

If possible: Make friends, cause it has more control then you now.
