Well, in this 'naruto gets one for all fanfiction', a great plot could be that Naruto gets One for All and it starts to attract the attention of villains from both the Naruto universe and the My Hero Academia universe (where One for All comes from). He has to deal with new threats that are after this power. Meanwhile, he tries to train with his new power secretly so as not to alarm his village too much.

In the 'naruto gets one for all fanfiction', an interesting plot might be that Naruto gets One for All during a strange encounter with a mysterious figure. This new power makes him question his own identity and purpose. He wonders if he's still the same ninja he was before. As he tries to master One for All, he also has to face the fact that some in his village might see this new power as a threat. So, he has to find a way to prove that he can use it for the good of the village while also exploring the limits of this foreign power.
One possible plot could be Naruto suddenly obtaining the One for All power. He might struggle at first to control it as it's a very different kind of power from the chakra he's used to. His friends would be both amazed and a bit worried. Naruto could then try to incorporate this new power into his fighting style, perhaps creating new jutsu that combine his ninja skills with the raw strength of One for All.
A cool plot could be Naruto being reincarnated as an enemy of Konoha in a parallel universe. He has all his memories but has to fight against his former friends and home. This would lead to a lot of internal conflict for him. Also, he could be reincarnated into a time where there are new and strange forms of chakra that he has to learn to master in order to save the world again. For example, a chakra that is a combination of nature and spiritual energy.
Well, sometimes in such fanfiction, the framing is part of a larger conspiracy. Maybe it's not just about getting Naruto in trouble, but it's a scheme by an enemy village to create chaos within the Leaf Village. They might plant false evidence of Naruto collaborating with the enemy, which then leads to a series of events where Naruto has to prove his innocence while also dealing with the distrust of his friends and the village elders. It can make for a really engaging read as we see Naruto struggle against all these odds.
One possible plot could be Naruto getting married to a character from another anime, like Sakura from his own world crosses over to the world of One Piece and marries Luffy. This would create a lot of chaos as Naruto tries to adapt to the new world while also dealing with his new relationship. He could use his ninja skills in the pirate world, and there would be a lot of comical and action - filled situations.
One plot twist could be that the 'pregnancy' actually turns out to be a way for Kyuubi to transfer its remaining power to Naruto in a more permanent and extreme way. Instead of just lending power, it's like a total fusion of their essences. Another could be that the 'pregnancy' is a ruse by an enemy who has manipulated Naruto's connection with Kyuubi to make it seem like this is happening, when in fact they are trying to steal the power that would be created from such a union.
In such a fanfiction, an interesting plot point could be that Naruto's chakra starts to mix with the Sharingan's power in unexpected ways. This could lead to the creation of a new type of Sharingan or a new power altogether. Maybe Naruto's Uzumaki bloodline affects the Sharingan in a way that no one expected. Also, the power struggle within Naruto as he tries to balance his own values with the new power of the Sharingan could be a great source of internal conflict and an interesting plot point.
One possible plot development could be that the village is thrown into chaos without Naruto. His friends might initially feel lost but then come together to find a way to bring him back. For example, Sasuke could put aside his differences and join forces with the others, realizing Naruto's importance to the village and to him personally.
Well, he might get a chakra - enhanced katana. It could be really cool as it can cut through almost anything with the added chakra power.
In this fanfiction, perhaps Naruto uses the Caged Bird Seal to his advantage in a unique way. For example, he could find a way to tap into the seal's energy and use it in his battles. This could make his fight scenes more intense and unpredictable. Also, the seal might attract the attention of some powerful enemies or allies who are interested in its power.
In some of these fanfictions, Naruto goes back and tries to save his parents. He might use his knowledge of the future to outwit the enemies that were once too powerful for his family. Also, he could introduce new jutsus earlier in the timeline, which would change the power dynamics in the ninja world. And sometimes, he gets involved in the politics of the village much earlier, trying to make Konoha a more just place from the start.
Well, often one interesting plot point is how Naruto first acquires the Susanoo. Maybe it's through some kind of forbidden jutsu or a strange connection to an Uchiha ancestor. Another plot point could be how he trains to control it. Since the Susanoo is such a powerful and complex ability, seeing Naruto struggle and then succeed in taming it is really engaging. And of course, how his enemies react when they see Naruto with this new power. They might be shocked or even more determined to defeat him.
