Well, it could be really interesting. Maybe Naruto, with his ninja skills and strong sense of justice, enters the Twilight world and discovers he has a sister in Rosalie. He might use his abilities to protect the Cullens from their vampire enemies. And Rosalie could learn some things from Naruto about loyalty and perseverance.
Their relationship could be a bit of a push - and - pull. Naruto would probably be the more open and affectionate one, trying to get Batman to open up more. Batman, on the other hand, might be a bit standoffish at first. But over time, he would come to appreciate Naruto's positive energy. They could have arguments about how to handle villains, with Naruto preferring to try and understand and redeem them, while Batman is more about justice and punishment.

A 'naruto father of sasori fanfic' plot could be really interesting. Naruto, being Sasori's father, would have to deal with Sasori's natural talent for puppetry.

There could also be a sub - plot about Sasori's mother, who could be someone from Naruto's past or a new character entirely.

This would create an interesting contrast between his old self and his new, more alluring persona.
