Man this shit sounds like a flout to human in basic
I may understand that people have lost some single parts of their body, and really needs organic transplantation to stay alife and reach their goal.
But at some point you need to ask yourself, you mixed 2 different persons in a unnatural way.. and which one is the actual living from them both or did they just fusion together ?? How to call them ? I don't know it kinda sounds sick man, if 2 persons decide to stick together like that I wouldn't be sure if I still would want to know them
