One common theme is self - discovery. The original characters often have to figure out their place in the Naruto Shippuden world. Another is friendship, as they interact with the known characters. And power - up is also common, like the oc developing a new jutsu or getting stronger in some way.
One great 'naruto shippuden oc fanfic' is 'The Hidden Legacy'. It has an interesting original character who has a unique jutsu. Another is 'A New Path in Konoha' which focuses on an oc's journey to become a great ninja in the village. There's also 'OC's Redemption' that shows how an oc overcomes their past and fits into the Naruto Shippuden world.
One great Naruto x Hinata fanfic in Naruto Shippuden is 'A New Beginning'. It focuses on their relationship development after Naruto returns from his training. The story beautifully depicts how Hinata's feelings for Naruto become more obvious and how Naruto starts to see Hinata in a new light.
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.
One interesting concept could be an OC who is a long - lost relative of a major character, like a cousin of Naruto. This OC could have a unique chakra ability that they discover during their journey. Another idea is an OC from a different hidden village who comes to Konoha as an exchange student and has to adapt to the new environment while also hiding a secret mission.
One great 'Naruto Shippuden Naruhina Fanfic' is 'A New Beginning'. It explores their relationship post - war in a very heartwarming way. The author does an amazing job of depicting Hinata's growth and how Naruto finally realizes his true feelings for her.
I really like 'Sharingan Awakening in Shippuden Fanfic'. It focuses on a character who discovers their Sharingan in a unique situation during the Shippuden era. The story is full of action and emotional moments as the character struggles to master their new power.
One great fanfic could be about their adventures before Naruto was born. It might explore their relationship dynamics, how they trained together and supported each other. Maybe in this fanfic, Jiraiya tries to convince Tsunade to take on more dangerous missions with him, showing his trust in her abilities.
First, create a well - rounded male OC. Give him a clear backstory, like where he's from, his family situation, and what his goals are in the Naruto Shippuden world. For example, he could be from a small village destroyed by the Akatsuki and his goal is revenge. Second, make his abilities unique but still fit within the Naruto universe. Maybe he can control a special type of chakra that no one else can. Third, focus on his relationships with the canon characters. If he has a rivalry with Rock Lee over who's the better taijutsu user, it can create great tension and interesting storylines.
There's also 'A Male OC's Journey in the Shinobi World'. This fanfic focuses on how the male OC adapts to the harsh environment of the Naruto Shippuden universe. He forms an unlikely friendship with Sasuke which is interesting to read. The story also delves into his struggle to find his place among the powerful shinobi and his attempts to master new jutsus.
