There could be a fanfiction where Naruto gets a vision through Madara's eyes. He sees the past events that led Madara to become the powerful and feared ninja he was. This vision makes Naruto understand Madara on a deeper level. He then tries to find a way to prevent the same kind of tragedies that happened in Madara's life from happening again in the present ninja world. Naruto could use this new - found understanding to bring about peace in a different way than he originally thought.
Another interesting concept is the idea of Madara's eyes having a sentient will of their own. In the fanfiction, the eyes could influence the character who possesses them, sometimes for good and sometimes for bad. It would create an internal struggle within the character as they try to maintain their own will while also dealing with the desires of Madara's eyes.
In fanfiction, if Naruto gets Madara's eyes, he might gain new and powerful abilities. For example, he could potentially have enhanced visual powers like the Sharingan's precognition in battle. His fighting style would likely change as he adapts to these new eyes. He might also face new challenges as his body adjusts to the foreign power of the Uchiha eyes.
In fanfiction, if Naruto takes Madara's eyes, he might gain incredible new powers. For example, he could potentially combine the power of the Sharingan or the Rinnegan with his own Sage Mode. This could make him an even more formidable opponent, able to predict attacks more accurately and use powerful genjutsu.
Maybe the fanfic has a plot where Madara's eyes are actually sentient in a way. They start to communicate with a young and inexperienced ninja. The eyes guide the ninja to become stronger and more powerful, but also lead them down a path that might not be entirely ethical. The ninja then has to decide whether to continue following the eyes' guidance or break free from it.
The plot implications could be huge. It could create a new dynamic between Naruto and the Uchiha clan. Naruto would have a part of Uchiha heritage, which might make some Uchiha more accepting of him. Also, it could lead to new alliances as other villages might see Naruto as an even greater threat or an even more valuable ally. And in terms of character development, Naruto would have to deal with the new power and the potential darkness that comes with the Sharingan.
The story would become much more intense. Naruto would suddenly have access to powers that were previously exclusive to the Uchiha. This would shift the power balance in the ninja world.
In the fanfiction scenario where Madara gives Naruto his eyes, Naruto's abilities would transform. Firstly, the basic Sharingan abilities would improve his reaction time and perception. He could analyze his opponents' moves better. With the potential for the Mangekyo Sharingan, he could gain unique and powerful techniques. For example, if he got a fire - based Mangekyo ability, he could combine it with his own Rasengan or other wind - based jutsus to create new and more powerful attacks. This would not only make him stronger in battle but also give him new ways to protect his friends and the village.
Madara could also save Naruto by using his knowledge of the ninja world. Maybe he has some inside information about a plot against Naruto and he intervenes in time to stop it. He might have discovered a secret plan by an enemy group and takes action to keep Naruto out of harm's way. This could involve manipulating events behind the scenes or directly confronting the threat.
It could involve exploring the power of Madara's eyes in unique ways. Maybe the fanfic could show how someone else in the Naruto universe gets a taste of the power of Madara's eyes and how it changes their perspective and abilities. For example, a young ninja might accidentally gain some of the abilities related to Madara's eyes and has to learn to control it while facing various challenges in the ninja world.
