Another plot idea is that her relationship with Sasuke could be very different. Since she's raised by Jiraiya, she might be more confident and less desperate for Sasuke's attention. She could focus more on her own growth as a ninja and on protecting the village in her own way. Also, her training with Jiraiya could lead to her having a special bond with the toads, and she might be able to summon really powerful toads earlier than in the original story.
One idea could be that she grows up with a different fighting style, influenced by Jiraiya's more fluid and unpredictable techniques. Maybe she becomes really good at using transformation jutsu in unique ways, like transforming into mythical creatures Jiraiya told her about during their travels.
A possible plot could involve her dealing with the Akatsuki in a different manner. With Jiraiya's teachings, she might be more strategic and less impulsive. For example, when facing Itachi, instead of being immediately intimidated, she could use the knowledge Jiraiya imparted about genjutsu counter - measures. This would make for a very different Naruto in terms of character development and how she impacts the overall story.
One idea could be that as a female Naruto, she might face different challenges in the ninja academy. For example, the boys might underestimate her at first. Minato could train her in unique ways, like focusing more on stealth and agility which are often associated with female ninjas in some stories. This could lead to her developing her own signature jutsu that combines her natural strength and her newfound skills.
One idea could be that Jiraiya focuses on Naruto's rasengan training in a more extreme way. He takes Naruto to a secluded place full of natural challenges like strong water currents or rocky terrains. There, Naruto has to constantly adapt and use his rasengan in different situations to overcome obstacles. Another plot could involve Jiraiya teaching Naruto some secret clan jutsus that he discovered during his travels, which could give Naruto an edge in future battles. And also, Jiraiya could train Naruto in stealth and espionage skills, which are essential for a shinobi but Naruto hasn't had much focus on before.
Well, it might have Naruto learning all sorts of cool jutsu directly from Jiraiya from a very young age. Maybe he'd grow up to be even more powerful and confident earlier in life. He could also inherit Jiraiya's carefree yet determined attitude more deeply.
One plot idea could be Naruto learning some unique and forbidden jutsus from Jiraiya. For example, a jutsu that allows him to communicate with the spirits of the past Hokages for guidance. Another could be Naruto and Jiraiya going on a special mission to a hidden and dangerous land where Naruto has to use all his skills and new knowledge from Jiraiya to survive. Maybe they discover a new chakra source there.
Well, perhaps there could be a plot where they both get trapped in a mysterious dimension. In this dimension, they have to rely on each other's skills. Jiraiya's knowledge of sage mode and Orochimaru's various jutsu could be combined to find a way out. It could also explore their relationship in a more in - depth way as they face different challenges together.
Well, one possible plot could be that Naruto grows up with a stronger sense of toad-based jutsu from the start. He might learn more about the toad world and its secrets earlier, which could make him a more formidable ninja even as a young genin. For example, he could use some basic toad techniques during the Chunin Exams, surprising his opponents.
A possible plot could be that Naruto, under the care of Tsunade and Jiraiya, discovers new aspects of his heritage. Tsunade might know some secrets about the Uzumaki clan that she shares with Naruto. Jiraiya, being his godfather - like figure, helps him explore these new revelations. Meanwhile, the Akatsuki could still be a threat, and Naruto, with his new skills and knowledge, has to fight against them to protect the village and his loved ones.
One possible scenario in this fanfiction could be that Naruto grows up with a more balanced upbringing. Tsunade might teach him medical ninjutsu and how to control his emotions better. Jiraiya, on the other hand, would surely train him in powerful combat techniques and in the ways of the sage. Naruto would probably be more mature and well - rounded at an earlier age, with a combination of Tsunade's tough love and Jiraiya's adventurous spirit guiding him.
A plot could involve Tsunade and Jiraiya in their younger days. Maybe they both had a crush on each other but were too shy or focused on their ninja training to admit it. As they grow older and more experienced, their feelings resurface. Tsunade might start to notice how Jiraiya has always been there for her, through her losses and tough times, and this realization blossoms into love.
One interesting idea could be how Naruto's character might develop differently with a unique influence. Maybe the '18' represents 18 different mentors or experiences that shape him in ways not seen in the original story.
