Naruto would likely be more confident. With the Sannin as his guardians, he'd have access to top - notch training and knowledge. He might not have the same insecurities as in the original series. For example, Tsunade could help him with his self - esteem, Jiraiya with his understanding of the ninja world, and Orochimaru (in a reformed way) with his knowledge of forbidden jutsu, making him a more well - rounded and confident shinobi.
In this kind of fanfiction, Naruto's growth would be exponential. With Tsunade as a mother figure, he'd be more in tune with his emotions and better at handling stress. Jiraiya would instill in him a sense of adventure and the importance of protecting the village at all costs. Orochimaru, in a less - evil - than - original - story way, could have given Naruto an edge in understanding the nature of chakra and how to manipulate it in unique ways. The story could also explore how Naruto would deal with the different moral compasses of the Sannin, especially Orochimaru's more gray - area ethics.
One possible plot twist could be that Naruto's unique way of raising the Sannin changes their personalities completely. For example, Jiraiya might become more reserved and studious under Naruto's influence. Another could be that the Sannin end up teaching Naruto secrets that were lost in the original timeline. Maybe Tsunade reveals a new form of medical ninjutsu that Naruto then uses to save many lives in future battles. Also, Orochimaru might turn away from his dark path earlier, leading to a different power structure in the shinobi world.
Well, a possible plotline is Naruto growing up with a different fighting style influenced by the Sannin. He might combine the brute strength and earth - based techniques from Tsunade, the sneaky and unpredictable jutsu from Orochimaru, and the toad - related ninjutsu from Jiraiya. This would make him a very versatile and powerful ninja in the fanfiction. Also, his personality could be shaped by their different outlooks. Tsunade's tough love, Orochimaru's calculating nature (but in a good way in this fic), and Jiraiya's carefree yet wise attitude.
I think Orochimaru would be the most changed. In the original series, he was very much into dark and forbidden jutsu. But if Naruto were to raise him, Naruto's positive influence would likely steer him away from that path. He might become more of a healer or a researcher into non - harmful ninjutsu.
His relationships would be quite different. With Sasuke, he might be more of a mentor - like figure early on, as he'd have more knowledge and power from the Sannin's teachings. His relationship with Sakura could be more of an equal partnership in combat, since he'd have more medical knowledge from Tsunade. And with Kakashi, he'd probably still respect him, but he'd also have his own unique insights from the Sannin that could make their interactions more like exchanges between equals.
It could be Jiraiya. He has a really strong bond with Naruto already. He's taught Naruto a lot in the original story too. So in the fanfic, his training could be the most in - depth, covering things like advanced rasengan variations and how to fight against really powerful enemies. His influence on Naruto's character development would also be significant.
Jiraiya would be the most interesting. He has a wild and carefree personality which could be a great contrast to Naruto's initially lonely and neglected state. Jiraiya is also very knowledgeable about the outside world and has many powerful jutsus, especially those related to the toads. He could take Naruto on adventures, teaching him not just about being a ninja but also about life in general. His connection to the prophecy about the 'Child of Prophecy' could also add an interesting layer to the story, as Naruto might be groomed in a different way to fulfill that prophecy under Jiraiya's guidance.
One good Naruto Sannin fanfic could be 'The Sannin's Legacy'. It delves into the backstories of the Sannin and how their actions shaped the Naruto world in ways not fully explored in the original series. Another great one might be 'Sannin Reunion', which focuses on a scenario where the Sannin come together again for a common cause. And 'Sannin: The Hidden Tales' is also a great fanfic as it uncovers some hidden secrets about the Sannin.
One of the best is 'Naruto's Sannin Adventure'. In this, Naruto embarks on a journey with the Sannin, and each stop on the journey teaches him something new about ninja life, power, and friendship. The author does a great job of portraying the relationships between Naruto and the Sannin. There's also 'The Sannin and Naruto's Destiny' which explores how the Sannin are intertwined with Naruto's destiny. It has a complex plot that keeps you hooked from start to finish.
