Perhaps in this fanfiction, Weiss discovers a strange portal and steps through it, ending up in the Naruto world. She meets Naruto and is intrigued by his ninja abilities. They could start training together, with Weiss learning some ninja techniques and Naruto learning about Dust. Their combined skills could then be used to protect Konoha from a new threat that has some similarities to the Grimm from her world.
One idea could be a crossover where Naruto's world is in danger and he somehow gets transported to Weiss's world. There, he has to team up with Weiss to fight a common enemy. Maybe a powerful dark mage that threatens both their universes. Another plot could involve Weiss learning Naruto's ninja techniques and incorporating them into her combat style, creating a unique fighting style that surprises their friends and foes alike.
Another plot could involve a RWBY character ending up in the Naruto universe. Say, Weiss gets sent to Konoha. She might initially struggle with the different culture and the use of chakra, but eventually she could use her Glyphs in unique ways by combining them with chakra. This could also lead to some interesting interactions between her and the ninja students there.
One plot idea could be that the Faunus OC is initially misunderstood by Weiss. For example, the OC might be a cat Faunus and Weiss has some preconceived notions about cat Faunus being sly.

One idea could be that Naruto and Weiss are both summoned to a strange dimension. They initially don't trust each other due to their different backgrounds. But as they face various challenges like powerful monsters, they start to learn from each other's skills. Naruto teaches Weiss about his chakra control and shadow clones, while Weiss shows Naruto how to use Dust magic. Eventually, they become friends and find a way to return to their respective worlds.
Perhaps Salem discovers a way to use Naruto's chakra for her own evil purposes. So, Naruto has to find a way to stop her while also dealing with the new and unfamiliar world of RWBY. He might learn some new skills from the RWBY characters along the way.
One idea could be that Naruto and his friends get transported to the RWBY world. They team up with Ruby and the gang to fight a common enemy that combines the threats from both universes, like a group of powerful ninja - Grimm hybrids.
Well, a 'naruto x rwby fanfic' could center around a training arc. Imagine Naruto training the RWBY team. He could help Ruby improve her speed and combat skills by teaching her some of his ninja movement techniques. Yang could learn from Naruto how to better control her temper during battles, similar to how Naruto had to control his Nine - Tails' chakra. Meanwhile, the Naruto characters could also be learning about the Grimm and how to fight them.

Well, a possible plot for 'naruto in rwby fanfiction' is that Naruto is mistaken for a new type of Huntsman. He then has to prove himself in the Beacon Academy.

In the Naruto world, she would face different challenges than in RWBY, and having to think on her feet like Naruto does could make her a more well - rounded fighter and person.
