It could also be a heartwarming story where Naruto in diapers is being taken care of by his parents. This would be an AU (alternate universe) since his parents died early in the original series. It could show a different side of Naruto's family life and how his parents would have interacted with him as a baby, with some tender moments and family - oriented adventures.
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.
One possible plotline could be Tsunade teaching Naruto more about medical ninjutsu. Since she is a great medical ninja, she could pass on her knowledge to Naruto, which would add a new dimension to his skills. Another aspect could be her guiding Naruto in leadership, as she is the Hokage. This might help Naruto in his future role as a leader in the village.
Perhaps in the fanfic, Futa is a new character in the Naruto world who has some sort of connection to Tsunade's past. Naruto gets caught in the middle of their relationship. It could involve Futa having some secrets that Tsunade is desperate to know, and Naruto helps in uncovering those secrets while also growing as a ninja himself.
A plot could involve a time - travel scenario. Sayo Hitsugi somehow gets sent back in time and meets a younger Naruto. Together, they try to change certain events in the ninja world's history that could have a major impact on the future. Or perhaps there is a plot where Naruto has to protect Sayo Hitsugi from a group of rogue ninjas who are after her for some unknown reason. Naruto's loyalty and determination to protect his friends would be put to the test.
Maybe in the fanfic, Death is not a traditional Grim Reaper - like figure but rather a form of an evil curse that has been plaguing the ninja world. Naruto, being the hero, is the only one with enough positive energy and determination to face it. He could start by gathering allies who have also been affected by this 'Death' curse. Together, they form a plan. Naruto would be the vanguard, using his speed and strength to break through the defenses of the curse - based Death and then use his willpower to shatter it completely.
One possible plotline could be that Naruto discovers his new wings during a battle. Maybe he's in a really tough fight against a powerful enemy and suddenly, wings sprout from his back. This gives him an unexpected advantage in the air, allowing him to dodge attacks more easily and launch aerial assaults. Another could be that the wings are a result of some new chakra form he unlocks. He has to learn to control them, which could lead to some comical training scenes with his friends like Sasuke and Sakura trying to help him figure out how to fly.
One possible plotline could be that Naruto has a sudden and extreme power-up that makes him overconfident. This overconfidence leads him to challenge Neji in a spar that gets out of hand and he ends up 'destroying' Neji in the sense of completely overpowering him. Maybe Naruto has unlocked a new form of his chakra that Neji can't counter with his Gentle Fist technique.
