One possible plot could be Naruto teaching Sasuke some new and unique jutsu. For example, Naruto, as a sensei, might introduce Sasuke to a special type of nature transformation that he learned during his travels. This could lead to Sasuke evolving his own fighting style and becoming even more powerful.
A plot twist could be that their deaths were faked by themselves. They might have discovered a great threat to the village that required them to go undercover. So, they faked their deaths to deceive the enemy. Or, perhaps their deaths lead to the awakening of an ancient evil that was sealed long ago. And it turns out that their deaths were somehow a sacrifice to keep this evil at bay for a while, but now the remaining characters have to find a way to defeat it once and for all. This would completely change the direction of the fanfiction.
In this fanfiction, perhaps Naruto becomes the sensei of Team 8 and takes them on a special mission. Along the way, he shares his own experiences as a ninja and how he overcame his challenges. He might also help Shino understand the importance of teamwork on a deeper level, since Shino is often more independent. Naruto could also introduce new training methods that are different from what they are used to, which would lead to the growth of each member of Team 8.
One possible plot could be that Naruto travels back in time. He then uses his knowledge of future events and his ninja skills to train Kushina. Maybe he helps her become an even more powerful kunoichi and also gives her advice on her relationship with Minato.
Well, perhaps in this fanfiction, Naruto travels back in time and becomes Kakashi's sensei. He could use his knowledge of future events to guide Kakashi in a different way. For example, he might prevent Kakashi from making some of the mistakes he made in the original story. Also, Naruto could introduce Kakashi to new forms of chakra control or combat strategies that he learned from his own adventures. This would change the dynamic between them and also have a significant impact on the events in the Naruto world as Kakashi is an important character.
Well, one possibility is that Anko could teach Naruto some unique jutsu. Maybe she'd focus on his stealth skills since she's good at that. For example, she could train Naruto to be better at sneaking around and surprising his opponents, like how she moves in the shadows.
Well, one possibility is that Naruto could end up in the world of Mahou Negima Sensei by some sort of magical accident. Maybe he'd be confused at first, trying to figure out the new magic - based rules and different social norms. He might then use his ninja skills in unexpected ways, like using his speed to dodge magical attacks. And he could form new friendships with the characters from Mahou Negima Sensei, teaching them about ninjutsu in return.
Well, perhaps in the fanfiction, Naruto being Kurenai's sensei could lead to him teaching her some unorthodox methods. Since Naruto has his own way of doing things, he might introduce her to new ways of fighting or thinking that completely revolutionize her ninja skills. This could create interesting storylines where Kurenai has to adapt to Naruto's teaching style while still holding on to her own values.
Well, the plot might involve Kushina seeing Naruto's potential right from the start and training him intensively. She could also share her own experiences of growing up as an Uzumaki, which could help Naruto better understand his heritage. And perhaps they go on special missions together where Kushina guides Naruto not just in combat but also in making tough decisions. There could be a lot of emotional moments as Kushina fills the role of both a sensei and a mother - like figure to Naruto. Also, Kushina could introduce Naruto to other Uzumaki - related things like ancient seals or special chakra control techniques that were unique to their clan.
The plot might start with Sasuke attacking the village again, but this time with a more sinister plan. Naruto, who has always tried to bring Sasuke back, finally snaps. He realizes that Sasuke is too far gone. Naruto's revenge could be a long - drawn - out process. He first has to figure out Sasuke's motives and weaknesses. He might team up with some unlikely allies, like Orochimaru who also has a history with Sasuke. Their encounters would be full of intense combat, with Naruto determined to make Sasuke pay for his actions.
A possible plot could be that Karin discovers a hidden power within herself that could either save or destroy the ninja world. Naruto and Sasuke, being two of the most powerful ninjas, are called upon to either help her control it or stop her if she goes rogue. This would create a complex dynamic between the three characters as they grapple with trust, power and their own personal beliefs.
