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.
The fanfic could portray Naruto as having greater physical strength and endurance. Maybe he can take more hits and keep fighting, while Minato might get tired more easily. Also, Naruto's strategic thinking in combat could be shown as superior, allowing him to outwit Minato in battles.
One reason is Naruto's vast chakra reserve. His Uzumaki heritage gives him an almost unlimited supply, which can be emphasized more in fanfic. So he can keep going in a fight longer than Kakashi.
One reason is that Naruto has the Nine - Tails' chakra. In fanfic, this power can be further enhanced or manipulated in ways that make him far more powerful than Sasuke. Another reason could be his more outgoing personality. He might be able to form alliances more easily, leading to him having more resources and power - ups at his disposal.
Often, in fanfic, Naruto is made stronger than Itachi because the writers want to explore new story arcs. If Naruto is stronger, new and exciting battles and relationships can be created. For instance, Naruto could be the one to protect Sasuke from Itachi in a different way. Also, Naruto's positive and determined nature makes him a popular character to be super - powered in fanfics.
One reason could be Naruto's unwavering determination. He has always been able to push past his limits. In many battles, his willpower has been a key factor in his victory. Another could be his unique chakra nature and the amount of chakra he has at his disposal. Naruto has a vast reserve of chakra, which gives him an edge in long - drawn battles. Also, his ability to form strong bonds with others might contribute. These bonds could potentially unlock new powers or give him the strength to fight against Kaguya.
Well, in some fanfictions, Naruto might be considered stronger because he has access to more powerful forms and jutsus. He might have mastered the Nine - Tails' chakra in a more advanced way than Minato could. Also, Naruto has trained with many powerful shinobi, which could give him an edge in strength compared to Minato.
One feat could be Naruto's ability to use Sage Mode more effectively. In some fanfictions, he might be able to maintain it for longer periods or use it in combination with his other powers more seamlessly. This gives him an advantage over Minato who didn't have the same level of Sage Mode proficiency.
One possible reason could be Naruto's pent - up anger towards Minato for leaving him as an orphan. He might feel that Minato sacrificed himself without fully considering the consequences for Naruto.
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.
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.
