To act like Jiraiya in fanfiction, Naruto should adopt Jiraiya's courage. Jiraiya was never afraid to face strong opponents. Naruto could show this by taking on difficult missions alone or standing up against powerful villains without hesitation. Jiraiya was also a bit of a loner at times, and Naruto could have moments in the fanfic where he goes off on his own to train or to think. This would add depth to his character, showing that he's not just the boisterous Naruto we know, but also someone who can be introspective like Jiraiya.
Naruto is often depicted as his usual enthusiastic and determined self. He is eager to learn from Jiraiya and respects Tsunade. Jiraiya is usually portrayed as the wise and sometimes lecherous mentor. He has a wealth of knowledge and experience. Tsunade is the strong - willed and tough - as - nails female character. She is respected for her medical skills and leadership. In fanfiction, these traits are often exaggerated or explored in different situations.
The training makes Naruto more confident in his abilities. Jiraiya constantly challenges Naruto and as Naruto overcomes these challenges, he realizes his own strength. He starts to believe in himself more, which is evident in the way he faces stronger opponents without hesitation later on. Also, Jiraiya's teachings about the ninja way and the importance of protecting those you love make Naruto more determined and focused on his goals.
Jiraiya might comfort Naruto by sharing his own experiences. He could tell Naruto about the times he faced difficulties and how he overcame them. For example, he might talk about his training with the toads and how he grew stronger through perseverance.
One plot idea could be that Naruto decides to follow in Jiraiya's footsteps as a spy. He disguises himself and infiltrates an enemy organization. Just like Jiraiya, he has to gather intelligence while also being careful not to blow his cover. Another idea is that Naruto starts his own training school in the style of Jiraiya, teaching a new generation of ninjas his unique techniques and the values he learned from Jiraiya.
Jiraiya's training in the fanfiction might focus on Naruto's inner strength as well. He could help Naruto better understand and control the Nine - Tails' power. This new - found control would give Naruto a sense of calm and authority. His character would shift from being just a loud - mouthed underdog to a more respected and powerful ninja. Naruto would also learn about loyalty and sacrifice from Jiraiya, which would shape his values.
Their relationship would be very strong. Jiraiya would see Naruto as not just a student, but also as a connection to Minato. He would be strict but also very affectionate. Naruto would look up to Jiraiya as a father figure, since he never really had one. They would share many adventures together, with Jiraiya teaching Naruto about life, love, and ninjutsu.
His character would develop with a stronger sense of loyalty towards Jiraiya. He would inherit Jiraiya's values like protecting the weak and seeking justice. Naruto would also be more well - versed in the ninja arts and history due to Jiraiya's teachings. This would make him more respected among his peers at an earlier stage. Moreover, he might be more patient and less impulsive as Jiraiya could teach him the importance of thinking before acting.
He might be more confident from the start. Since Jiraiya is known for his charisma and self - assurance, Naruto could inherit some of that. He may not be the underdog we saw in the original series as much.
Jiraiya would likely become more protective. He has always been a bit of a free spirit, but with a son in the picture due to time travel, he would be more cautious. His focus would shift from just his own adventures and spying to ensuring his son's safety and growth.
Jiraiya's reaction might be complex. He might be in awe of Naruto's new power but also sad about his departure. He could see it as a natural progression in Naruto's journey, yet still feel a pang of loneliness. He might start to reflect on his own life and training methods, wondering if he could have done something differently to keep Naruto with him. At the same time, he would be eager to see what Naruto will achieve in the world with his newfound abilities.
