Okay, long story short, I want to know if there is an SCP already with someone who cannot heal and cannot die. I have an image of a living, conscious, severed head being stored cruelly in a locker on the site somewhere, with other body parts stored perhaps in different lockers, but he can still move and feel all of them as if they were connected to his body. Occasionally, different parts may be approved for experimentation (i.e. Will this kill him? or If we plant an explosive in his severed leg and discharge, will he still be able to feel all the parts?)
I also want to know if this is somewhat out of character, which I think it is (the foundation is generally not unnecessarily cruel) and if so, what could be done to draw the idea back into a more believable, acceptable sphere?
