Soon after Dark Naruto appears, berating Konoha's people for how quickly they changed their ideals of Naruto and have started sucking up to him which sickens him. He mentions that he is the manifestation of the darkness that exists in the heart of Naruto and that Nine-Tails has taken a particular liking to him.
