A plot could be that a succubus is sent to the Naruto universe as part of a deal between dark forces. She targets Naruto because of his growing power. But as she gets closer to him, she starts to feel real emotions for him instead of just using him for power. This creates a conflict within her as she has to choose between her original mission and her new - found feelings.
A Naruto and Shuri fanfiction could also focus on a training arc. Imagine Shuri wanting to learn some of Naruto's ninja skills, like how to move stealthily or how to use kunai effectively. Naruto, on the other hand, could be interested in learning about Wakandan science and technology from Shuri. They could train together in the Wakandan forests, with Naruto teaching Shuri basic ninja moves and Shuri teaching Naruto about the latest Wakandan inventions. This cross - training would not only strengthen their individual abilities but also create a deep bond between them.
Maybe a group of succubi are summoned accidentally in the Naruto universe. They cause chaos as they are used to a different kind of world. Naruto and his friends have to figure out how to send them back without harming them, while also dealing with the succubi's alluring powers that are affecting some of the villagers.
One idea could be a crossover where Naruto's world is invaded by a threat from Hawkgirl's universe. Naruto, with his determination and powerful jutsu, teams up with Hawkgirl, who has her mace and flight abilities. They start off not trusting each other due to their different backgrounds but gradually learn to work together as they face the common enemy.
A third idea is to set the fanfiction in a modern-day scenario where the Dalmatians become famous on social media. The 102 Dalmatians have their own Instagram account and attract the attention of a big Hollywood producer. But there are also some jealous animals who try to sabotage their new - found fame.
One idea could be a crossover where a character with ice - make abilities from Fairy Tail ends up in the Naruto universe. They could use their ice - make skills to help the Naruto characters in battles, like creating ice barriers to protect the Hidden Leaf Village from an attack. Another plot could involve a Naruto character discovering they have an ice - make - like kekkei genkai and has to learn to control it while facing challenges from enemies who fear this new power.
Perhaps a magical creature mistakes Naruto for its long - lost love who was known for being extremely charming. As a result, the creature bestows upon Naruto a temporary transformation that makes him sexy. This could lead to humorous situations where Naruto is confused by all the new attention he's getting. He might accidentally use this new - found allure to his advantage during a battle, distracting his opponents with his looks while also using his regular ninja skills.
A plot could also be where Naruto is wrongly accused of being a succubus - like being a danger to the village because of some strange powers he has. Kushina, even though she has passed away, appears to Naruto in his mind or as a spirit guide. She gives him the strength and wisdom to prove his innocence and show that his powers can be used for good, rather than being seen as something evil like a succubus.
One idea could be a story where a new character discovers they have a unique fire - based ability that is different from the typical fire jutsu in Naruto. They could struggle to control it at first, causing chaos in their village, but then learn to harness it with the help of an old master.
A very creative 'Naruto' fanfic idea could be a time - travel one. For example, Naruto travels back in time to prevent the Uchiha massacre. Another idea is a fanfic where the ninja world is merged with the fairy - tale world. So Naruto could be fighting against the Big Bad Wolf or teaming up with Cinderella. And a fanfic where the Sharingan has a completely different power, like the ability to control the weather, would also be a very creative concept.
One idea could be Naruto swapping bodies with Kakashi. Naruto would then have to deal with Kakashi's more laid - back attitude towards life while also handling his responsibilities as a teacher. He might also be able to learn some new jutsu from Kakashi's memories. Another idea is Naruto swapping with Gaara. This would be interesting as they both have had very different upbringings and Naruto could understand Gaara's pain more deeply. It could also lead to a better understanding between the two villages.
