answer me this, will you be alive if hit directly by a nuke?
good question.... As nobody have done it yet... you can't answer that for sure.
and i prove my point, if nobody has survived from a nuke what makes you think they will? just think for a minute. waste of thread.
Yes people have survived nukes and atomic bombs, its quite common, your point really isnt valid, in the shinobi world anything can happen, they could have used body flick and escaped for all we know
