Naruto is stronger in fanfiction because of his ability to connect with others. He has made friends all over the ninja world. This network of friends often provides him with support in battles, whether it's intel or actual combat help. Also, his training under Jiraiya was very comprehensive. Jiraiya taught him not only combat skills but also how to be a better person. This made Naruto grow both physically and mentally. And compared to Sasuke, Naruto seems to be more adaptable to different fighting styles in fanfiction, which gives him an edge in combat.
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.
There are fanfictions where Naruto, using his Uzumaki clan's sealing techniques along with his chakra, is able to break through Sasuke's genjutsu. Genjutsu is one of Sasuke's strong points usually, but Naruto's unique abilities give him the upper hand. Also, in certain stories, Naruto's connection to the nature energy in his Sage Mode is so strong that he can heal himself during a fight with Sasuke, while Sasuke doesn't have such a convenient self - healing ability.
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.
In fanfiction, it's possible for Naruto to be stronger than Goku. Fanfic writers often tweak the power levels and rules of the characters' universes. For example, if the fanfic writer decides to nerf Goku's Saiyan abilities while enhancing Naruto's Sage Mode and all his ninja skills to an extreme level, Naruto could end up being stronger.
Well, it depends on the specific fanfiction. There are various interpretations out there. Some fanfictions focus on Naruto's growth after the original series and give him abilities like super - charged chakra control or the ability to nullify Madara's strongest jutsu. However, in the original canon, Madara is an extremely powerful opponent. But in fanfiction, the rules can be bent to make Naruto stronger.
Well, it depends on the specific fanfic. Some fanfictions might give Naruto an edge over Madara by, say, having him master some super - secret jutsu that completely nullifies Madara's powers. Or they could boost Naruto's physical and chakra capabilities to an extent where he can easily defeat Madara. However, in the original Naruto lore, Madara is an extremely powerful foe, but fanfic authors have the freedom to change the power balance as they see fit.
Another plotline might be Naruto's strength leading to a different kind of peace in the ninja world. Since he's stronger, he can enforce his ideals more effectively. He could start a new era of cooperation among the ninja villages by using his power to make the other villages see the benefits of unity, and Sasuke might be reluctantly following his lead.
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.
Naruto is better in fanfiction because he has a more relatable journey. He starts from being an outcast in the village but still manages to hold onto his positive attitude. His will to protect everyone is unwavering. For example, he never gives up on Sasuke even when Sasuke turns his back on the village. His growth is not just in power but also in character, which makes him a more appealing character in fanfiction compared to Sasuke who is often more brooding and focused on revenge.
