One common theme is the development of their relationship. Writers often explore how they go from being just comrades to having deeper feelings for each other. For example, in many fanfics, there are moments where they start to understand each other on a more personal level during missions or while dealing with village politics.
One great piece of fanfiction could be 'The Bond Between Shikamaru and Temari'. It delves deep into their relationship post - Shippuden, showing how they support each other in rebuilding the ninja world. It has some really well - written emotional moments between them.
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.
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.
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.
It's possible that in some very niche or dark fanfictions, Naruto Shikamaru could be presented as a sociopath. But this is a huge deviation from his canonical character. In the original series, Shikamaru is known for his laziness on the surface but deep down he has a strong sense of duty and connection to those around him. Fanfiction writers may use the idea of him being a sociopath to add an edgy or different perspective, but it goes against the essence of who he is in the official story. For example, his relationships with Naruto, Choji, and others show his capacity for friendship and loyalty, which is the opposite of sociopathic behavior.
Well, normal Naruto Shippuden fanfics are likely to be centered around the adventures, growth, and battles of the characters. They might explore different what - if scenarios within the framework of the Naruto universe. But 'naruto shippuden diaper fanfic' is likely to be more of a novelty or a very specific and strange take on the characters. It might not have the same depth or connection to the original story as normal fanfics do. For example, normal fanfics could focus on how a character overcomes a difficult battle, while a 'diaper fanfic' would be more about a really odd situation involving diapers which has little to do with the main Naruto themes.
Another interesting novel is 'Naruto Shippuden: Kakashi Hiden - Lightning in the Icy Sky'. It focuses on Kakashi's story and his past, which is really fascinating. There are a lot of details about his relationships and his growth as a ninja.
