Re: Asspultropolis
If it's about his edo tensei (i can't remember if he did it to his edo tensei?), either way, his body wasn't obliterated to nothing and as such he was able to be (in a sense) brought back via edo tensei, which if I recall, uses the corpse matter to recreate it as closely as possible to it's state just prior to death. So it's a (forbidden) technique that as explained in the manga has taken a crazy long time to perfect.
This however, is a completely different kettle of fish.
Prior to Edo Tensei that was explained as locking part of himself away to be released at the right time, if I recall, he never manifested in the real world, did he not?well Naruto was able to punch his dad and he was a spirit...
