There could be a really interesting story where Naruto, with his ninja skills, adapts to being a vampire - werewolf hybrid in the Twilight world. Maybe he uses his shadow clone jutsu to confuse other vampires or werewolves. He could also bring in his own sense of honor and friendship from the Naruto universe into this new and dark world of Twilight.
In such a fanfiction, Naruto's chakra system might interact in strange ways with his new vampire - werewolf nature. For example, his chakra could enhance his superhuman abilities even more. Also, his relationships would be quite different. He might have a hard time fitting in at first, but then he could start to form alliances with some of the more open - minded characters in the Twilight world, like Carlisle from the Cullen family who is known for his acceptance of different beings.
A Naruto - vampire - werewolf hybrid in Twilight fanfiction could explore his transformation. How does he deal with the bloodlust as a vampire and the wild nature of a werewolf? He might use his training from being a ninja to control these urges. And his backstory as an orphan in Naruto could be paralleled with some of the outcast characters in Twilight. This could lead to some really deep and emotional storylines as he tries to find his place in this new and strange world.
