The plot might involve Naruto having to adjust to the new world of RWBY while also dealing with his own godlike status. He could end up teaching the RWBY characters some of his jutsu, like the Shadow Clone Jutsu, which could be useful in battles against large numbers of Grimm. And perhaps there would be some sort of conflict where his powers are both a help and a hindrance, like attracting unwanted attention from powerful enemies in the RWBY world.
In this fanfiction, Naruto's godlike abilities could change the power dynamic in RWBY. For instance, his ability to sense chakra might be translated into sensing the Aura in RWBY. He could use his Rasengan in creative ways against the Grimm. There could also be a story arc where Naruto has to find a way back to his own dimension but realizes he has a responsibility to help the RWBY world first. Maybe he discovers some connection between the two dimensions that was previously unknown, like a shared origin of certain powers or a common enemy that exists in both dimensions.
Naruto's powers would be quite unique in RWBY. His ability to create shadow clones could be used for scouting or for overwhelming opponents. His Rasengan could be a powerful attack against Grimm.
One possible plot could be that Naruto, with his godlike powers, somehow ends up in the RWBY universe. He teams up with Ruby and the gang to fight a new, powerful enemy that threatens both their worlds. His unique jutsu and combat skills would add a new dimension to the battles in RWBY.
One possible main antagonist could be a powerful being that controls the different dimensions and sees Naruto's hopping as a threat to his order. Another could be an evil version of Naruto from another dimension who wants to stop our Naruto from spreading his 'good' influence. Maybe a group of rogue dimension - travelers who are causing chaos in different dimensions and Naruto has to stop them.
One idea could be Naruto arriving in a dimension where chakra doesn't exist and he has to learn new powers. Another could be him meeting alternate versions of his friends in different dimensions, like a super - evil Sasuke in one dimension. Maybe he also discovers a dimension where the Akatsuki are the good guys and he has to figure out how to work with them.
A really exciting plot could involve Naruto getting trapped in a time - loop within the Juubi dimension. Every time he tries to find a way out, he ends up back at the starting point. He has to figure out how to break the loop by solving a mystery related to the Juubi's power. This would require him to interact with different versions of characters he knows, who may have different personalities and motives in this strange dimension.
One interesting plot could be Naruto traveling to a dimension where the Akatsuki are the heroes. It would be a complete role - reversal, and Naruto would have to figure out how to interact with them. Another could be a dimension where everyone has a different type of chakra, like water - based chakra for all shinobi, and Naruto has to adapt his skills.
The plot could involve Naruto having Alucard's powers and abilities, like his vampiric strength and regeneration. Maybe he uses these new powers to protect Konoha from a new kind of threat that normal ninja skills can't handle.
One possible plot could be that Naruto, in his godlike state, tries to understand Kaguya's past and motives more deeply. He might use his newfound power to communicate with her on a different level, perhaps even showing her a different way of seeing the world. This could lead to a redemption arc for Kaguya, where she starts to regret her past actions.
Perhaps Naruto, in this fanfiction, makes a deal with a devil - like entity to gain ultimate power, making him godlike. But this power comes with a price, like losing his connection to his friends. So he has to struggle between his new - found power and his old self. He could be on a path of destruction until someone or something makes him realize the error of his ways. This would create a complex plot full of internal and external conflicts.
The plot could center around Naruto's journey to adapt to his blindness while still being godlike. He may start by feeling frustrated and lost, but then he begins to train his other senses intensively. His relationship with Sasuke could take an interesting turn as Sasuke might see Naruto in a new light. There could be a sub - plot where Naruto has to prove himself to the village elders again, since they are skeptical about his ability to protect the village while blind. And all the while, he's still got these incredible godlike powers that he's learning to use in new and different ways.
