Since Tsunade is known for her medical skills, Naruto could be trained in advanced medical ninjutsu much earlier. This would not only make him a more versatile shinobi but also give him an edge in battles as he could heal himself and his comrades quickly. Jiraiya, on the other hand, would introduce Naruto to more complex and dangerous combat scenarios. His training might involve long - distance missions and battles against powerful opponents to toughen him up. Also, the combination of Tsunade's strict discipline and Jiraiya's more laid - back but still effective teaching style would create a unique learning environment for Naruto.
One challenge is the time gap between their eras. Sakura is from a more modern time in the Naruto series, while Hiruzen is from an earlier generation. So, it can be difficult to create a believable scenario where they interact in a way that doesn't seem forced.
It could be Orochimaru. Since Orochimaru has a long - standing feud with Jiraiya and is always up to no good. If Naruto ditches Jiraiya, Orochimaru might see this as an opportunity to manipulate Naruto. He could try to convince Naruto that Jiraiya was holding him back and that he can offer Naruto more power, all while having his own evil plans for Naruto.
Yes, there are quite a few. Some fanfictions might focus on their interactions within the Hidden Leaf Village. For example, they could be involved in a joint mission where Hiruzen, as the experienced Hokage, imparts some of his wisdom to Kushina. This could lead to a great story of mentorship and friendship.
One common theme is friendship. Given their different positions in the village, a story could be built around how they become friends. Another theme could be protection. Since Kushina is a jinchuriki, Hiruzen might be involved in protecting her from those who would seek to use her power for evil.
There are quite a few. One such fanfic is 'The Mentor's Wisdom' where Hiruzen imparts his knowledge and skills to Naruto in a detailed and engaging way.
One idea could be Hiruzen teaching Naruto some of the most secret and powerful jutsu in the village. For example, a special fire - style jutsu that was once used by the First Hokage. This would give Naruto an edge and also show the bond between him and Hiruzen. Another plot could be Hiruzen training Naruto in the art of political leadership. Since Naruto is destined to be a great leader, Hiruzen could impart his wisdom on how to handle different clans and political situations within the village.
One plot idea could be that Sakura, through some time - travel jutsu, ends up in Hiruzen's era. She uses her medical ninjutsu knowledge to help in a major epidemic that is plaguing the village at that time. Hiruzen, impressed by her skills, takes her under his wing as a sort of special advisor for medical matters in the village.
There may be some interesting Kushina and Jiraiya fanfictions. You could search on platforms like Archive of Our Own or FanFiction.net. When looking, pay attention to the tags and summaries to find ones that focus on the elements you're interested in, such as their friendship or potential collaborations in the story.
One great fanfic could be about their adventures before Naruto was born. It might explore their relationship dynamics, how they trained together and supported each other. Maybe in this fanfic, Jiraiya tries to convince Tsunade to take on more dangerous missions with him, showing his trust in her abilities.
