Another plot could be that in a different dimension or alternate reality, older Naruto meets young Sasuke. They have no prior knowledge of each other, but Naruto senses something special in Sasuke. They start training together, and Naruto helps Sasuke unlock new powers. As they grow closer, they face threats to this new world they are in, and their bond becomes the key to saving it.
One possible plotline could be that older Naruto, having achieved great things in the village, takes young Sasuke under his wing. He tries to teach Sasuke the values he has learned over the years, like the importance of friendship and protecting the village. Sasuke, being young and headstrong, might be initially resistant but gradually comes to understand Naruto's point of view.
A fanfiction could also be set in a scenario where older Sasuke and young Naruto are accidentally sent to a different dimension. In this strange new world, they have to rely on each other to survive. Sasuke's calm and calculated nature combined with Naruto's boundless energy and optimism would make for an interesting dynamic. They'd have to find a way to get back home while also dealing with the unique challenges of this new dimension.
One possible plotline could be that Naruto, having a fundamental difference in ideology with Sasuke, decides to take a stand. Maybe Sasuke is on a path that Naruto believes will destroy the village or their friends. So Naruto uses his newfound powers, perhaps a combination of Sage Mode and Nine - Tails chakra, to directly confront Sasuke. Naruto could try to break Sasuke's resolve through sheer force and the power of their friendship memories.
One possible plotline could be that the older brother was thought to be dead but actually survived and returns to protect Naruto from the shadows. He might have some special powers or knowledge that he uses to keep Naruto safe without revealing his identity at first.
One possible plotline could be that Naruto, in his 'godlike' state, is pushed to the brink by Sasuke's actions which threaten the safety of the village. Naruto might see no other option but to end Sasuke's life to protect everyone he loves. For example, if Sasuke were to ally with a powerful and evil force that was bent on destroying Konoha, Naruto's extreme power could be the only thing to stop him.
One possible plotline could be that they go on a mission to a far - off land to retrieve a powerful and ancient artifact. Along the way, Hinata's Byakugan helps them detect hidden traps and enemies. Sasuke uses his Sharingan to analyze combat situations quickly, and Naruto with his Nine - Tails chakra provides the brute strength. They face many challenges together and in the process, their teamwork and understanding of each other deepens.
One possible plotline could be that Sasuke has been misled by some false information. Maybe he believes that the female Naruto is in some way a threat to Konoha's future. So he kidnaps her to keep her away from the village. However, as he spends time with her, he realizes his mistake and they end up working together to clear up the misunderstanding.
Well, perhaps Naruto and Sasuke are forced to join Orochimaru. Maybe Orochimaru has some kind of leverage over Konoha that makes them comply. In this fanfiction, they could start to learn unique jutsus from Orochimaru but also have to constantly resist his more evil intentions. They might also meet some interesting characters within Orochimaru's lair.
Maybe in this fanfic, Sasuke has gone too far in his quest for power and revenge. He starts attacking innocent people or trying to take over the Hidden Leaf Village. Naruto, as the hero, has no choice but to stop him. Naruto could use his talk - no - jutsu at first, but when that fails, he resorts to physical combat. He might start with his basic Rasengan and gradually level up his attacks as Sasuke counters with his Chidori and other powerful jutsus. In the end, Naruto destroys Sasuke's evil intentions and either kills him or imprisons him, depending on the tone of the fanfic.
One possible plotline could be that Naruto is somehow influenced by a dark power. This power makes him believe that by taking Sasuke's eyes, he can gain ultimate power to protect the village. So, he sneaks up on Sasuke when he's vulnerable and steals his eyes. But then, he realizes the horror of what he has done and has to deal with the guilt and the consequences from both his friends and the village.
One possible plotline could be Naruto going back in time and meeting young Kakashi during his ANBU days. Naruto might be shocked to see the cold and distant Kakashi at that time. He could try to break through Kakashi's walls and get to know the real him. Maybe Naruto would share some of his own experiences and wisdom from the future, which could have an impact on Kakashi's development.
