Perhaps Vette is a wanted criminal in her world and flees to the Naruto world. Naruto initially mistakes her for an enemy but then realizes she is just a misunderstood character.

I think Naruto and Vette would be the most interesting.

They would constantly be bouncing ideas off each other, Naruto with his ninjutsu and Vette with her technological know - how.

They could go on a mission to stop a powerful mutant villain who has plans to take over the world, using Naruto's chakra powers and Wolverine's adamantium claws.

A cool plot might involve an enemy that uses both Chakra and Infinity Stones' power. Naruto teams up with the Avengers. The Avengers are amazed by Naruto's ability to use his Nine - Tails' Chakra.

They combine their powers and skills, with Iron Man creating special suits for Naruto that can enhance his jutsu, and together they fight the powerful foe.
Maybe Ahsoka ends up in the Naruto world somehow. She is mistaken for a powerful shinobi at first. Naruto is intrigued by her different look and the strange weapon she wields.

Well, a plot could involve a villain in the Naruto world who is creating some sort of dark energy that is affecting both dimensions.
