"Dark Naruto!!" (闇ナルト!!, Yami Naruto!!) is chapter 493 of the original Naruto manga.
Summary[]
Naruto tries to defeat his "inner darkness", the product of his lonely childhood and the lone obstacle in his efforts to tame the Nine-Tails. They are equally matched, so the fight does not go anywhere. Since this is an internal struggle, Naruto returns his attention to the real world and asks Motoi how Killer B overcame the evil in his heart but Motoi couldn't. Naruto then requests that Motoi ask B, however, Motoi weighed down by the guilt of having once tried to kill B stated once again that he could not. He then offers to tell Naruto about B's background so that maybe Naruto could find the answer himself.
