If Naruto merged with Madara, the story might take a turn towards exploring new forms of ninjutsu. They could start teaching the new generation their combined techniques, and the ninja world would see a new era of powerful shinobi. Also, their relationship could be a central theme, with Naruto constantly trying to keep Madara's darker side in check.
In such a fanfiction scenario where Naruto merged with Madara, their chakra would blend in an unprecedented way. Naruto's vast chakra reserves combined with Madara's Uchiha blood and powerful chakra would make them an almost god - like entity. Their merged form could have abilities like instant teleportation across great distances, the power to nullify any ninjutsu with a simple thought, and they could also potentially reshape the very fabric of the ninja world, creating a utopia where all ninja clans live in harmony, using their combined knowledge and power to ensure there is no more war or hatred.
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.
At first, it might be very rocky. Naruto would be suspicious of Madara given his reputation. But as time goes on, if Madara shows genuine care and teaches Naruto useful skills, Naruto could start to respect him. Eventually, they could develop a father - son - like bond.
Often, the story starts with Naruto realizing the potential of a full merge. Then he has to overcome some internal struggles. After the merge, he usually goes on a power - up spree. He might take on stronger enemies that he couldn't face before.
One way the story could develop is that Naruto would have an innate understanding of powerful Uchiha techniques. Since Madara was a master of the Sharingan and had many powerful jutsu. Naruto might be able to quickly master the Sharingan if he inherits it. For example, he could use it to enhance his combat abilities against stronger enemies. He could also have a different relationship with Sasuke. Maybe instead of being rivals, they could be more like cousins with a shared heritage to explore.
Naruto's character would likely become more complex. He might start off as a more cynical version of himself, influenced by Madara's jaded view of the ninja world. But his natural kindness and will to protect others would still be there, just hidden deeper. As he grows, he would constantly struggle between Madara's teachings and his own inner values.
One possible way the storyline could develop is that Naruto would inherit some of Madara's powerful chakra and Sharingan - like abilities. Since Tsunade is known for her medical ninjutsu and superhuman strength, Naruto might also have a natural affinity for healing. This could lead to a new type of combat style for Naruto, where he combines his inherited skills with his own Rasengan - based techniques. He could use his Sharingan - like power to predict his opponents' moves and then counter with his Rasengan, while also being able to heal himself or his comrades in the heat of battle.
Naruto would likely become more open - minded. Since Madara is from an older generation and has a different perspective, Naruto would learn new ways of thinking. He might also gain more confidence, knowing that someone as powerful as Madara has his back. This could make him bolder in his actions towards achieving peace in the ninja world.
Naruto would likely be more brooding. With Madara as his father, he might inherit some of that Uchiha intensity. He'd probably be more cautious about making friends, knowing the Uchiha's history of being ostracized.
His character would likely become more serious. Madara's influence would make Naruto think more about power and strategy. He'd be less impulsive perhaps.
