Well, Jiraiya being alive could mean a different path for Sasuke. Jiraiya might have been able to convince Sasuke to return to the Leaf Village earlier. He could have used his own experiences and wisdom to show Sasuke that there are other ways to seek revenge and power. And this could have led to a more united and stronger Leaf Village much sooner.
In a fanfiction where Naruto gets adopted by Jiraiya, Naruto's training would be intense and unique. Jiraiya has a lot of unorthodox methods. He could introduce Naruto to some very special and secretive forms of chakra control. Naruto might also learn more about the secrets of the Sage Mode much earlier. With Jiraiya's guidance, Naruto could form stronger bonds with other powerful ninjas that Jiraiya knew. This would give Naruto more allies and a greater understanding of the political and power dynamics in the ninja world.
In this fanfiction, Jiraiya might also take Naruto on some adventures. They could go on a journey to explore some hidden places in the Naruto world. Along the way, Naruto would learn not only about combat skills but also about different cultures and histories within the world, which would shape his character in new and interesting ways.
Well, Naruto with the Rinnegan trained by Jiraiya would be extremely powerful. Jiraiya could teach Naruto unique ways to use the Rinnegan's abilities. Maybe Naruto would combine Sage Mode with the Rinnegan powers, creating new and unbeatable jutsu. He could also use the Rinnegan's ability to see chakra flow to better understand his opponents and counter their attacks more effectively.
One possibility in a fanfiction where Jiraiya is alive could be that he returns during the Fourth Great Ninja War. He could use his vast knowledge and powerful jutsu to turn the tide of the war. Maybe he teams up with Naruto again and helps him master new forms of the Rasengan or other powerful techniques.
In such a fanfiction scenario, it could be due to a misunderstanding. Maybe there was false information spread about Naruto that made Jiraiya and Tsunade believe he had done something unforgivable. For example, an enemy could have framed him for a major crime against the village.
Well, one possibility is that Naruto could learn a great deal more about the past of the ninja world directly from Jiraiya. He might also get to witness some of the key events that shaped the present he came from. For example, he could be there when Jiraiya was gathering information on the Akatsuki, which would give him a huge advantage in dealing with them in his own time.
One thing that could happen is that Naruto would learn a lot more about the toad sage mode earlier. Jiraiya could start training him right away. This would give Naruto an edge in battles. He would be able to use the toad - related jutsu more effectively and have a different combat style.
Perhaps in this fanfic, Naruto would be more confident earlier in his life. Since Jiraiya is a strong and experienced ninja, his early presence in Naruto's life could provide a sense of security. They might go on missions together earlier, and Naruto could learn about the importance of teamwork and strategy from Jiraiya at a young age. This could potentially change the course of Naruto's development, making him a more well - rounded and powerful ninja much faster.
Well, one possibility is that Naruto has some kind of premonition in the fanfiction. So he quickly rushes to Jiraiya's location where Pein is attacking. And he uses his shadow clones cleverly, distracting Pein long enough to rescue Jiraiya. He could also have some secret help from a new ally or an unexpected power boost from within himself.
In this fanfiction, Boruto might learn some unique ninja techniques from Jiraiya. Jiraiya could see the potential in Boruto and train him in his own unorthodox ways. Maybe Boruto would be introduced to Jiraiya's toad summoning, which could add a whole new dimension to his combat abilities.
