The 'jiraiya vs pain' in RWBY fanfiction could be a battle of wits as much as a battle of powers. Jiraiya is a very experienced ninja, and Pain has his own ideology - driven powers. In a RWBY setting, the battle could be affected by things like Dust, the special energy source in RWBY. Jiraiya might be confused by this new element at first, while Pain could try to incorporate it into his attacks. It would be a clash of two different power systems and fighting styles.
Their relationship could become deeper as Jiraya risks his life more often to protect Naruto. Naruto starts to see Jiraya as a true father figure, someone he can rely on completely.
The biggest difference is the creativity of the fanfiction writers. In the anime, the fight follows a set storyline. But in fanfiction, anything can happen. For example, Naruto could suddenly gain a new power that was never in the anime. It's like a whole new world of possibilities.
Konan could be really interesting. In some fanfictions, she might have a different backstory or motivation that affects the Naruto vs Pain fight. For example, she could be secretly trying to stop Pain from going too far in his destruction of the Leaf Village.
In the fanfic, Jiraya might protect Naruto from the Akatsuki. He could disguise Naruto and lead the Akatsuki pursuers on a wild goose chase, using his vast knowledge of the ninja world to outwit them at every turn. This way, Naruto can continue his training without interruption.
It's really hard to say who would win. Jiraiya has his Sage Mode which gives him enhanced strength, speed, and perception. But Pain has the Rinnegan which allows him to use powerful abilities like the Six Paths techniques. In the RWBY fanfiction context, it might depend on how well they adapt to the RWBY world. If Jiraiya can quickly figure out how to use Dust to his advantage, he might have an edge. But if Pain can use his powers to disrupt the balance of the RWBY world, he could also come out on top.
It's hard to say for sure. If the fanfiction focuses on Hinata's growth, she could potentially defeat Pain through her own skills and some unexpected twists. But Naruto is also likely to be a major factor, so it could be a combined effort of both of them that overcomes Pain.
In this fanfiction, Naruto might be extremely enraged seeing Hinata in danger against Pain. Hinata, on the other hand, would likely show her newfound strength and determination. Maybe she'd manage to land a few surprise attacks on Pain before Naruto fully jumps into the fray.
Well, the Naruto vs Pain fight in the original series is epic. Fanfiction allows fans to explore different scenarios and what - ifs. Maybe they want to see different character developments during that intense battle.
Maybe in the fanfiction, Naruto loses his chakra early on in the fight against Pain. But then he discovers a hidden power within himself that is not related to chakra, like a spiritual power from his Uzumaki heritage, which he uses to turn the tables on Pain.
