Hinata saving Naruto from Pain in fanfiction can take on many forms. It could be that Hinata has been secretly training and has a new set of abilities that she unleashes to save Naruto. This not only changes the course of the battle but also the dynamics between the characters. Fanfic writers might also add some emotional elements, such as Hinata's inner thoughts and feelings during the rescue. This makes the story more engaging and gives readers a fresh perspective on the Naruto - Hinata relationship.
One common plot is that Hinata arrives at the crucial moment when Naruto is about to be defeated by Pain. She uses her Byakugan in a new and unexpected way to counter Pain's attacks. For example, she might be able to see a weakness in Pain's jutsu that no one else could.
Another plot twist could be that the situation Tsunade is in is actually a trap set by an enemy to lure Naruto in. So, while Naruto is trying to save Tsunade, he has to also deal with the real mastermind behind the whole thing. This would add an extra layer of complexity to the story.
Naruto's understanding of sacrifice could deepen. If he has to put himself in great danger to save Tsunade, he'll learn more about what it means to sacrifice for others. He might recall the sacrifices of his predecessors like the Hokages and use that as motivation to keep going, even when the odds are against him.
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.
Jiraiya could be a great addition. Since he was Pain's teacher, his presence could add a lot of depth to the story. He could offer insights into Pain's past and also help Naruto understand Pain better.
Naruto could inherit Tsunade's medical ninjutsu skills. This would be a huge addition to his arsenal. He could use it to heal his comrades more effectively during missions. Also, he might inherit her ability to store chakra in his forehead. This would give him an extra boost of power when he needed it most. And perhaps he could also learn some of Tsunade's more precise combat techniques that rely on her strength and accuracy.
In some fanfictions, Naruto might use his new jutsu that he's developed through intense training. He could overpower Kabuto with his Rasengan variations, like the Big Ball Rasengan, and rescue Tsunade while Kabuto is distracted by the powerful attack.
There is also 'Tsunade's Journey'. This fanfic delves into Tsunade's past, exploring her relationships with her former teammates and how those experiences shaped her into the strong - willed woman she is in the Naruto series. It might also include her adventures outside of the village in her younger days.
If Tsunade kisses Naruto, it could strengthen their relationship in a mentor - like way. Naruto might see it as a sign of deep respect and trust from Tsunade. He would likely feel more confident in following her guidance. For Tsunade, it could be a way of showing her pride in Naruto's growth.
