One possible plotline could be that Naruto gets an eye transplanted from an Uchiha. This new eye might give him the ability to use Sharingan techniques. He could struggle at first to control it, like Sasuke did when he first awakened his Sharingan. It might also change his perception of the ninja world, as he now has a power that was once exclusive to the Uchiha clan.
A possible plotline could revolve around the technology or magic behind Harry's prosthetics. The fanfic could explore how the prosthetic limbs and eye were created. Were they made by a combination of Muggle technology and wizarding magic? Or perhaps it was an ancient, forgotten magic that was rediscovered to create these prosthetics. The story could also focus on Harry's emotional state. He could initially feel self - conscious about his new body parts but gradually grow to be proud of them as he realizes they make him stronger in a way.
In the fanfic, it might be set in an alternate universe where Sakura has a different personality. She could be more aggressive and competitive with Naruto. During a sparring match, she goes too far and seriously hurts Naruto. This could then be the starting point of a story about Naruto having to forgive her and them rebuilding their friendship.
One possible plotline could be that Naruto leaves the village due to some sort of political unrest. He meets a girl from another land during his travels. They bond over their shared experiences of being outsiders in a way. As they travel together, they face various challenges like bandits and natural disasters. Their relationship deepens through these hardships and they eventually decide to get married. It could also involve Naruto teaching his new partner about the ninja way.
Another plot could involve Naruto being revived due to the strong will of the people. In the Naruto universe, the will of the people can have a strong influence. So, all the people who Naruto has helped and inspired over the years unconsciously create a kind of spiritual energy. This energy is noticed by a sage or some other powerful being who uses it to bring Naruto back. Once revived, Naruto uses his new - found spiritual connection with the people to fight an even greater evil.
One possible plotline could be that Naruto is granted wings as a result of some ancient and powerful jutsu he accidentally activates. With the wings, he could gain new abilities like enhanced speed in the air and new combat techniques. For example, he might be able to use the wind generated by his flying to create more powerful Rasengan attacks. Another plotline could be that the wings are a gift from a mysterious being who sees Naruto's pure heart and wants to help him in his fight against evil. He then has to learn to control the wings and use them to his advantage in battles against stronger opponents.
One possible plotline could be a comical take where Naruto, perhaps as a baby or in a situation where he's regressed to a younger state in diapers, accidentally uses his newfound baby - like clumsiness to his advantage in a prank - like way against his friends. For example, he might 'accidentally' spill something on someone while being carried, leading to a series of funny events.
One possible plotline could be that Naruto and Ino are on a mission together. They start off bickering like they used to in the original series, but as the mission progresses, they begin to understand each other better. For example, they might face a powerful enemy that forces them to rely on each other's unique skills. Naruto's brute strength and Ino's mind - control abilities could complement each other in combat. Another plotline could be a more emotional one where Ino helps Naruto deal with his inner demons related to his past. She could use her skills to get inside his head in a more positive way and help him come to terms with things.
Perhaps a plot where Himawari discovers a new and rare chakra ability, and Naruto helps her to understand and control it. They might go on a journey to find someone who can further teach her about this power. This could involve meeting old friends of Naruto's along the way and having various adventures together.
One possible plotline could be that Sakumo is in a dangerous mission situation where he is outnumbered and on the verge of defeat. Naruto, with his powerful jutsu and never - give - up attitude, arrives just in time. He uses his Rasengan to take out the main threats and then uses his shadow clones to rescue Sakumo from the surrounding enemies.
In this fanfic, it could be a fight in an alternate universe where Naruto and Hinata belong to rival clans. Their clans' long - standing feud forces them to fight each other. However, during the fight, they start to realize that the feud is baseless and they might even develop a new understanding of each other and their clans' history.
