Often, in fanfic, Naruto gets stronger by delving deeper into his Uzumaki heritage. Since the Uzumaki clan was known for their large chakra reserves, he could learn to fully tap into this potential. This might involve special training techniques passed down within the clan that were previously lost or forgotten.
Another common way is through cross - over elements. For instance, if the fanfic involves a crossover with another anime or a different fictional universe, Naruto could gain new powers or knowledge from that world. He might learn magic from a wizarding world or advanced technology - based combat skills from a sci - fi universe, which would significantly boost his strength.
In some fanfics, Naruto's emotional growth is tied to his physical strength. By facing and overcoming personal traumas or internal conflicts, he unlocks new levels of power. For example, if he finally comes to terms with his loneliness as a child or his complex relationship with the Nine - Tails, it could result in a power - up that makes him stronger both in terms of combat abilities and mental fortitude.
In many fanfics, Naruto gets stronger through unique training regimens. For example, he might encounter a powerful mentor who teaches him new jutsu or ways to enhance his chakra control. This could involve intense physical and mental exercises that push his limits far beyond what he learned in the original series.
One common way is in terms of power. In fanfics, Naruto might be given powers similar to Madara's, like his ability to control the Sharingan or some other powerful jutsu. Another way could be in their leadership style. Naruto might be shown leading in a more authoritarian way like Madara did, instead of his usual collaborative style in the original series.
One common way is by giving him new and extremely powerful jutsus. For instance, a fanfic might create a jutsu that allows Naruto to manipulate time, which is way beyond his original abilities. Another way is by making his physical strength and speed far greater than in the original series. He could be shown to move at lightning - fast speeds and lift mountains effortlessly.
One common way is by sharing its chakra. Naruto can draw on this extra chakra to increase his strength and speed. Another way is through its knowledge. Kyuubi has a long memory and can pass on useful information about the ninja world.
Often, Harry uses his intelligence and courage. He could find loopholes in Umbridge's rules and use them against her. For example, if she made a rule that was against the school's original code, Harry could prove it and get her in trouble. Another way is that he could get the support of the magical creatures at Hogwarts. If the centaurs or the house - elves had a problem with Umbridge, Harry could use that to his advantage to get her fired.
Often, in fanfic, Harry gets out of trouble with Umbridge by having allies. His friends from Gryffindor or other houses could band together. They could create a well - coordinated plan. For example, they might stage a false emergency in another part of the school. Umbridge, being the person in charge of discipline, would have to go and deal with it. This gives Harry the chance to escape. Or his friends could use spells to make it seem like Harry is in a different location while he actually slips away.
One way is through enhanced emotional bonds. If Naruto experiences a very strong emotion like extreme love or a sense of justice, it might trigger a stronger connection to the Kyuubi and thus more power. Another way could be through new types of seals. Maybe a fanfic writer creates a seal that not only contains the Kyuubi but also channels its power more effectively to Naruto.
Often, Naruto is shown using his ability to empathize. He has been through a lot himself, so he can understand the Hyuga clan's issues. One common way is that he tries to break down the barriers between the main and branch families. He might talk to the clan leaders and convince them to give more rights to the branch family, like allowing them to learn certain jutsu that were previously restricted.
One common way is through self - discovery. A character realizes their hidden potential and uses it to achieve their dream. For instance, a character might discover they have a rare bloodline ability that helps them become a powerful ninja, fulfilling their dream of being respected in the ninja village.
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.
