He could be a protector. Given his strong sense of justice and his powerful abilities, especially with the rinnegan, he would defend the people in the RWBY universe from threats. His ability to summon the various creatures with the rinnegan could also be used to fend off Grimm. For instance, he could summon Gamabunta to stomp on large groups of Grimm.
Naruto could be a mentor - like figure. His experience with different types of combat and his rinnegan - enhanced perception would allow him to guide the RWBY characters in battles. He might help Ruby improve her scythe - wielding skills by teaching her some of his sword - fighting techniques that he learned from Sasuke.
Naruto might also be a catalyst for change in the RWBY universe. His different way of thinking, influenced by his upbringing in the Hidden Leaf Village, could inspire the RWBY characters to think differently about their own world. His rinnegan powers could also open up new possibilities for research in the RWBY world, like how to better understand and use energy, whether it's chakra or Aura.
In the RWBY universe, Naruto would be exposed to different types of threats and challenges. This would force him to adapt and grow. For example, he would have to deal with the Grimm, which are very different from the enemies in his own world. His Kitsune powers might also evolve in response to these new challenges, and he could become more strategic in his fighting style.
The story could start with Naruto already being a well - known figure in his world with the rinnegan. A strange phenomenon occurs that links his world to the RWBY world. When he arrives, he's initially confused but quickly realizes he can use his skills to help. He might teach the RWBY characters some of his ninja techniques, like stealth and misdirection, while also learning about Aura and Semblance from them.
A Naruto mercenary in a RWBY fanfiction could be a wild card. They might be a hired gun for the bad guys, causing trouble for the RWBY team. Or they could be a lone wolf who ends up helping the heroes when it suits their own goals. Their role could also be that of a teacher, sharing Naruto - style combat knowledge with the RWBY characters.
In a fanfiction, their relationship could also be explored in terms of leadership. Naruto has led his team in many battles and has a sense of responsibility towards his comrades. Raven has her own group and her own way of leading. They could compare and contrast their leadership styles. Maybe they would have some disagreements at first, but as they get to know each other better, they could find a middle ground and lead a combined force against a greater threat in the RWBY universe.
If Naruto got the Rinnegan, he might become more cautious. The power of the Rinnegan is so great that he would realize he needs to be more careful with it. He wouldn't be as brash as before.
RWBY crossover RWBY fanfiction can enhance the universe by exploring new relationships. For example, characters who have never interacted much in the original series can form new bonds. This gives a deeper understanding of the characters' personalities. It can also expand on the lore. By mixing different elements from within the RWBY world, new aspects of the history, magic, and technology can be revealed.
One idea could be that Naruto Team 8 is transported to the RWBY world. They could team up with Team RWBY to fight against a common enemy, like the Grimm. Shino could use his bugs to detect the Grimm's movements in ways that the RWBY characters haven't seen before. Kiba and Akamaru could add an interesting dynamic with their more physical combat style.
The chakra system in Naruto could be related to Dust in RWBY. For example, fire - based chakra could be seen as a more natural and internal form of fire Dust. Naruto's clones could be used in RWBY battles in creative ways. They could be used for distractions against Grimm or other enemies, while the RWBY characters attack from different angles. Sasuke's Sharingan could have an interesting interaction with the Aura in RWBY. Maybe it could enhance one's ability to see through illusions or detect hidden threats more effectively.
Well, Ruby would likely be all - eyes and ears, soaking up every detail of the Naruto fanfiction. Since she loves stories, she'd be eager to explore this new - to - her world of Naruto through the fan - made tales. Weiss may compare the fanfiction's portrayal of ninjas and their abilities to what she knows from her own studies or experiences. Blake might see the different relationships in Naruto fanfiction and draw connections to the complex relationships in RWBY. Yang would be the most vocal in her reactions, shouting out her thoughts on the cool jutsus and epic battles in the fanfiction.
Well, Naruto's Rasengan could be combined with Ruby's Crescent Rose. For example, Ruby could use the spinning force of the Rasengan and incorporate it into her scythe attacks. It would add a new level of power and unpredictability. Sasuke's Chidori could be used in a similar way, perhaps with Weiss' Glyphs. She could create Glyphs that enhance and direct the power of the Chidori for more precise attacks. And Naruto's shadow clones could be used in RWBY battles. They could be used to distract Grimm while the RWBY characters set up more powerful attacks.
