Always wondered this. I know Flash is the fastest, but how durable is his body? I mean in relation to a normal human, i.e. if he gets hit by a meta powered opponent, do his bones break? If he gets hit by a stray bullet, presumably it pierces his skin/muscles. How hard are his bones and how strong is he? does he have superhuman strength, above a normal peak human like Batman?
I mean its ok being fast, but to actually do damage to someone like, say Superman, you're bones have got to be hard enough not to shatter on impact! Thanks.
