UOTE=Hyoga;3174569]Hmmm, I dont want to be mean, but people really need to read the manga before they post stuff. Its getting old having to explain to a few why something that has been explained about 20 times is the way it is.....example: why itachi and nagato have their eyes...[/QUOTE]
Lets assume the pages have been long and some people cannot go through it all so let me answer the question again like this: If Deidara came with his whole body, why shouldn't Itachi and Pain come with their eyes?
The impure world ressurection technique requires one's DNA and restores him at the prime of his strenght!
Pls don't ask again, seriously.
