as i'm expanding my knowledge base of characters i'm trying to do some research on Mr Fantastic, now the question is this, can he be killed?
he can stretch and warp his body in amazing ways, pretty much like Plastic Man, but not as versatile, and we know Plastic Man is pretty much immortal, does the same hold true for Mr Fantastic?
has he ever been mortally wounded? or effected in such a drastic manner than his life was in danger?
does radiation or aging effect him in the same way is does normal people, as his DNA is now unstable does he age at all?
