Sure. The characters are a huge part of Naruto Shippuden fanfiction. Fanfic writers use the characters to attract readers who are fans of those characters. They might focus on a character's backstory that wasn't fully explored in the anime and expand on it. Also, the interactions between characters in the original show give fanfic writers ideas for different scenarios in their stories.
By their unique abilities. Naruto's Rasengan, Sasuke's Sharingan, these abilities can be the starting point for many fanfiction ideas. Writers can think about how these abilities could be used in different battles or situations not shown in the original.
I don't think it's strange at all. Naruto is a very curious person. Fanfiction can offer new perspectives on his own life and the lives of his friends. He might learn something new about himself or get inspired by the creative ideas in the fanfiction. It could also be a form of entertainment for him during his downtime.
A Naruto x Hinata fanfiction could focus on a mission they go on together during Naruto Shippuden. They are forced to rely on each other in a dangerous situation. Hinata gets injured protecting Naruto, and Naruto is filled with a new - found determination to protect her. This experience deepens their bond, and Naruto starts to see Hinata in a whole new light, leading to the start of their romantic relationship.
A really interesting Naruto and Tsunade fanfiction in Shippuden could be set during the Fourth Shinobi War. Tsunade is leading the medical efforts, and Naruto is on the front lines. But Naruto gets severely injured and Tsunade has to use all her skills to save him. This near - death experience could bring them closer, and Naruto could gain a newfound respect for Tsunade's abilities and the sacrifices she makes for the village.
Sure, Naruto Shippuden has a manga. The manga provides the original story and inspiration for the anime adaptation. They share many key plot points and character developments.
One great Naruto Shippuden Akatsuki fanfiction could be about a new character who infiltrates the Akatsuki. This character might have a special power that the Akatsuki wants to use for their own ends. The story could explore the moral dilemmas the character faces as they get closer to the Akatsuki's inner workings. They could start to question whether the Akatsuki are all bad or if there's some truth to their motives.
I really like 'The Uchiha's Redemption'. It focuses on Sasuke's journey in a different light. Instead of just his revenge plot, it delves deeper into his internal struggles and his attempts to atone for his past mistakes. It's a great read for those who want to see more depth in Sasuke's character.
One of the most popular is 'Naruto Shippuden: Sakura Hiden - Thoughts of Love, Riding Upon a Spring Breeze'. It's popular because it shows Sakura in a new light, with her own adventures and growth.
Sasuke would likely be more critical. He'd scoff at some of the fanfiction that portrays him inaccurately. But he might also secretly enjoy the ones that show his growth and development in a new light. He'd be all like 'This one has some truth to it, but this other one is just nonsense'.
Yes, there might be some popular ones. However, it depends on the fanfiction platforms and the fan communities. Some stories might gain popularity because they offer a unique take on the Naruto Shippuden world with the addition of hypnosis. They could have interesting plot twists, like a character using hypnosis to turn allies against each other, which can attract a lot of readers.
