One great 'Naruto and Madara Uchiha' fanfiction is 'The Redemption of Madara'. It offers a unique take on how Madara could have been redeemed in the Naruto universe. It has a great plot that keeps you hooked from start to finish.
One popular theme is redemption. Many fanfictions explore the idea of Madara being redeemed through his interactions with Naruto. For example, Naruto's unwavering belief in the good in people might make Madara question his own actions and motives.
If Naruto becomes Madara Uchiha in fanfiction, it could drastically change the plot. Firstly, the relationships would be turned upside down. Naruto's friends might see him as an enemy, especially Sasuke who has a complex relationship with the Uchiha legacy. The power dynamics in the ninja world would also shift. Naruto, with Madara's power and knowledge, could either rule with an iron fist or try to reshape the world in a more extreme way compared to his original goal of peace. And the Akatsuki's plans would likely be disrupted as Naruto, in Madara's form, might have different motives regarding the tailed beasts.
Naruto would likely be more brooding and introspective. Since the Uchiha are known for their deep emotions and internal conflicts, he would inherit some of that. He might also be more ambitious in terms of power, as Madara was always seeking greater power.
One possible way the storyline could develop is that Naruto would inherit some of Madara's powerful Uchiha abilities, like the Sharingan or even the Rinnegan. This would completely change his power dynamics in the ninja world. He might also face different challenges and enemies, as there could be those who fear his newfound power or connection to Madara.
It would be very different from the original Naruto story. Naruto might have access to some of the Uchiha secrets and powers much earlier. His view of the Uchiha clan and the history of the ninja world would be shaped by Madara's influence. Maybe he would be more powerful from the start, having inherited some of Madara's abilities or knowledge.
One of the most interesting aspects is the character transformation. Seeing Naruto, who was always full of hope and positive energy, take on Madara's dark and brooding persona. It's like a complete 180 - degree turn. Another aspect is how the other characters react. For example, Hinata might be completely lost, not knowing how to deal with this new Naruto. Also, the power - up Naruto would get as Madara. He would have access to the Sharingan and all of Madara's combat skills. It would be exciting to see how he uses them in battles, especially against opponents he used to face as Naruto.
Madara would have to adapt to the different threats in RWBY, mainly the Grimm. In his world, he was used to fighting other shinobi and clans. The Grimm are a whole new type of enemy. However, his Sharingan would give him an advantage in detecting their movements. He might also try to find a way to use the Grimm's negative energy, similar to how he used negative emotions in his own world to fuel his power.
Yes, there might be such fanfictions out there. The Percy Jackson series and the Naruto world with Madara Uchiha are both quite popular, and fans often like to cross over different universes in fanfiction. It could be really interesting to see how Percy Jackson, with his own set of powers and personality from the Greek mythology - based world, would react to or be a fan of the powerful and complex Madara Uchiha from the Naruto universe.
One main theme could be redemption. Madara has made many dark choices in his life. Through the love of another, he could find a path to redemption. For example, if he falls in love with a healer who believes in the good in everyone, she could inspire him to make amends for his past actions.
