Well, Naruto with Madara's hairstyle would look quite different. His usually spiky blonde hair would be replaced by Madara's long, dark hair. It might make him look more serious and less of the goofy, energetic Naruto we know. His face might seem more angular with that hairstyle, and it could also give him an air of mystery, like Madara had.
Sasuke might be a bit taken aback at first. He's used to Naruto's normal look, and this change could make Sasuke see Naruto in a new light, perhaps as a more formidable opponent or an even stranger ally. Sakura would probably be shocked too. She might tease Naruto about it at first but then grow to accept it. Kakashi would likely raise an eyebrow and make a comment about how Naruto is always full of surprises with his new look.
In a Naruto fanfiction where he has Madara's attitude, he could become more power - hungry. Madara was always seeking power to reshape the world according to his ideals. Naruto might start to view the tailed beasts not as friends but as tools for greater power. He could try to gather more chakra and perhaps even attempt to unlock new forms of power that are more in line with Madara's dark and ambitious nature, which would shock his comrades and enemies alike.
Well, if Naruto has Madara's DNA in the fanfiction, it could potentially enhance his physical strength. Madara was known for his great combat skills, so Naruto might inherit some of that power, like being even more proficient in hand - to - hand combat. Also, his Sharingan - related abilities could be affected. Maybe he could gain some of Madara's unique Sharingan powers, such as more powerful genjutsu or better perception skills.
Well, in such a fanfiction, it might start with Naruto being in a situation where he becomes Madara's pet. Maybe at first, Naruto is defiant but as time passes, he could start to understand Madara's motives in some strange way. Madara, on the other hand, might initially see Naruto as just a possession but gradually develop a sense of attachment. It could be a really strange and complex relationship that unfolds as the story progresses.
Well, Naruto would become extremely powerful. He could probably master all kinds of new jutsu. His already formidable combat skills would be enhanced to a whole new level. Maybe he could even use Madara's unique space - time ninjutsu more effectively than Madara himself. With this new power, he could potentially reshape the ninja world and bring about a new era of peace.
With his friends in Konoha, they would be initially worried. But those who truly know Naruto, like Shikamaru and Sakura, would support him in his decision. They would help him adjust to not having that power and encourage him to find his own path again. However, some of the younger ninjas who looked up to Naruto because of his great power might be disappointed at first.
One possible plot development could be Naruto facing internal struggles. He has always been Naruto Uzumaki, and now with Madara's DNA, he might question his identity. Another could be that the village starts to view him differently. Some might fear his newfound power, while others might see him as a potential threat. There could also be a plot where Naruto has to learn to control the new powers that come with Madara's DNA quickly, as an enemy emerges who can only be defeated with these new abilities.
In this fanfiction, Naruto's character development could be seen as a counterpoint to Madara's. Naruto is all about hope, friendship, and protecting the village. Madara has been through a lot of pain and betrayal which led him to a path of destruction. If Naruto is like Madara in this fanfiction, his development might involve a struggle between his own beliefs and the allure of Madara - like power and ruthlessness. However, Naruto would probably still find a way to use any new - found power in a more benevolent way compared to Madara.
Yes, there are likely some fanfictions out there with such a premise. Fanfiction writers often come up with creative and out - of - the - box ideas like this. However, it's not part of the official Naruto storyline.
