Yes. In many fanfics, Naruto is often depicted as stronger than Jiraiya. Naruto has the potential to grow far beyond his master. He has unique powers like the Nine - Tails chakra and has mastered many advanced jutsu over time, which can make him stronger in fan - created storylines.
One reason is his Nine - Tails chakra. It gives him a huge power boost that Jiraiya doesn't have. Another is his ability to learn quickly. Naruto has shown throughout the series that he can pick up new jutsu fast.
Well, Naruto has had the advantage of learning from many great shinobi over time. He also has a unique bond with his friends which could potentially give him more strength. Minato, on the other hand, had a shorter lifespan to develop his powers. Naruto has had more time to grow and surpass his father in strength.
Yes, in many fanfics Naruto is depicted as stronger than Kakashi. Fanfic authors often like to explore the growth potential of Naruto to an extreme level, surpassing his former teacher.
In a lot of fanfics, Naruto is stronger than Sasuke. Naruto has always had an incredible willpower and in fanfics, this can be translated into him achieving greater power levels. His ability to make friends and allies can also lead to him getting more support and resources in the story. For example, he might get some special training from an ancient sage that Sasuke doesn't have access to. Also, his positive attitude can attract more powerful beings to help him out, which gives him an edge over Sasuke in terms of strength.
Well, it depends on the specific fanfic. Some fanfics might focus on Naruto's growth post - Shippuden and give him abilities that make him stronger than Itachi. For example, they could have Naruto master a new form of Sage Mode that gives him an edge over Itachi's Sharingan - based techniques. However, other fanfics might keep Itachi's power level relatively high and not have Naruto overtake him. So, there's a lot of variation among different fanfics.
In some fanfics, Naruto can be made stronger than Goku. Fanfic writers have the freedom to manipulate the power levels and abilities of characters. They can give Naruto new and overpowered abilities that surpass Goku's. However, in the original canon of their respective series, Goku has extremely high power levels and abilities that are on a different scale.
One possible reason could be that Naruto feels he has learned all he can from Jiraiya at that point. Maybe he wants to explore his own path independently and test his skills without Jiraiya's constant guidance.
A fanfic like this might explore how fem Naruto's presence affects Jiraiya's typical behavior. Jiraiya is known for his pervy tendencies in the original series, but with a fem Naruto, he might have to control himself more. It could also be about how fem Naruto looks up to Jiraiya as a strong ninja and a source of wisdom, and how she tries to learn from him to become a great kunoichi.
One great Jiraiya and Naruto fanfic is 'The Mentor's Legacy'. It delves deep into how Jiraiya's teachings continue to influence Naruto even after his death. It has some really heart - warming moments where Naruto reflects on their time together and uses Jiraiya's wisdom in his battles.
