Lab (female part)

You're the one from the picture... and female (I'll make a male part too) You choose which kind of mix you are, but you must have the same features like the black monster.... which is your true form, but you're often into your human form anyway. You can switch between both forms anytime you want to. Story: A group of scientists created you into a lab to study you. Later they wanted to use you as their weapon. They call you Experiment 666 cause your true form seems like a female vision from the devil. They treat you more like an object instead of an living being. Will you accept your fate or escape from this lab? Will you become a hero or an villain? Your choice. I hope this is good enough for you girls (and boys).
