Well, Boruto might be really shocked. He has seen Naruto in his normal state, but seeing Naruto in the 4 - tails form through a fanfiction would be wild. He might be amazed at the power his father once had to control such a powerful and wild form. He could also start to understand more about Naruto's past struggles.
Boruto could have a mix of emotions. On one hand, he would be proud of his father for being able to handle the 4 - tails form. On the other hand, he might feel a bit intimidated. In the fanfiction, if it shows Naruto in some intense battles in the 4 - tails state, Boruto might think about how he can live up to that kind of power and legacy. He could also start to train harder, inspired by what he reads in the fanfiction.
In a 'naruto saves boruto fanfiction', Naruto might use his powerful jutsu like Rasengan to fend off enemies threatening Boruto. He could also use his experience and wisdom to guide Boruto out of a difficult situation, perhaps one involving a powerful new villain in the ninja world.
In a 'Boruto meets teen Naruto' fanfiction, Boruto could be amazed by his father's skills as a teen. He might see Naruto's determination in a new light and gain a deeper understanding of his own potential. Maybe they'd train together, with Naruto teaching Boruto some of his old - school jutsu.
In such a fanfiction, Naruto could share his old ninja tales with Boruto. Maybe he'd tell about his battles against the Akatsuki. Boruto would be in awe, seeing his father in a new light.
Well, in such a fanfiction, Boruto might be really shocked to see his father as a teenager. Maybe they'll have a sparring match where Teenage Naruto shows off his wild and unrefined yet powerful skills, and Boruto has to adapt to fighting this different version of his dad. They could also have some heart - to - heart talks about Naruto's dreams back then and how Boruto can better understand his own path.
Well, they might be really confused at first. Since RWBY is from one universe and Xerath is from League of Legends. The RWBY characters could be intrigued by Xerath's powerful magic and his tragic backstory as told in the fanfiction. They might question his motives and how his existence could impact their own world.
They might be shocked by the historical events. RWBY characters are used to their own world of Grimm and Huntsmen. The war's scale and the real - world brutality could be overwhelming for them. They could also be inspired by the heroism shown in the fanfiction, perhaps learning lessons about teamwork and sacrifice that they can apply in their own battles against the Grimm.
The RWBY characters' reactions would also depend on the writing style of the fanfiction. If it's a more comical take, they could be making jokes about Broly's appearance or his over - the - top power displays. But if it's a darker, more serious fanfiction, they might be genuinely afraid of Broly and have to figure out how to deal with this new and dangerous entity.
Another possibility is that Naruto's sickness is a sign of a greater imbalance in the chakra world. The Nine - Tails, being a powerful source of chakra, could be at the center of this imbalance. So, the story could revolve around Naruto and his friends trying to restore the balance while also taking care of Naruto's health. This would involve a lot of exploration of the Naruto universe's lore and the relationship between different chakra entities.
Naruto could use his Four Tails form to fight a new and powerful enemy that the normal ninja of the Hidden Leaf can't handle. For example, an enemy with the ability to nullify regular chakra attacks.
In the 'naruto trains boruto fanfic', Naruto might teach Boruto some powerful ninja techniques. For example, he could show Boruto how to master the Rasengan more effectively. Maybe he'd also train Boruto in the art of stealth and how to read an opponent's moves better.
