Fanfic: Naruto becomes like Madara. How could this transformation happen in the story?

One possible way is through some sort of powerful jutsu gone wrong. Maybe a forbidden jutsu that was meant to do one thing but instead warped Naruto's being and made him take on the form and some of the characteristics of Madara Uchiha. It could also be the result of some dark magic or curse that was placed on him by an enemy who wanted to disrupt the balance in the ninja world.

If Naruto were to become like Madara in fanfiction, it would be a huge shift. Naruto has always been about hope and friendship. But like Madara, he could start to see the ninja world as something that needs to be reshaped by his own hands, regardless of the cost. He may abandon his village's values and try to impose his own version of order. This would lead to conflicts with his former allies. For example, Sasuke might be one of the first to oppose him as Sasuke has his own ideas about the ninja world and would not easily accept Naruto's new Madara - like ways.

Another aspect could be in Naruto's leadership. As he grows older, he realizes the importance of Minato's calm and collected leadership in Konoha. Naruto might start to mimic Minato's diplomatic approach when dealing with other villages, just as Minato was respected for his ability to maintain peace and alliances. He could learn from Minato's past actions and start to handle village politics and international relations in a more Minato - like way.

It could also be that a villain from the Shazam universe tries to take over Naruto's world. In the process, they create a situation where Naruto's chakra system gets infused with the magic of Shazam. This would be a really interesting development as Naruto would have to figure out how to use his new powers in a way that doesn't conflict with his ninja training. He might use his new - found flight ability to quickly get to different battle locations and his super strength to overpower enemies that were previously difficult to defeat.

Well, one way could be through some sort of strange magical or scientific experiment. Maybe a rogue ninja or a mad scientist creates a device that accidentally fuses Naruto's chakra with Frieza's essence. This would start to change Naruto's physical and mental state, gradually making him more like Frieza.

Well, it could start with Naruto being exposed to some dark chakra that warps his mind, making him adopt Bane's ruthless and power - hungry ways. Maybe he loses all his friends in a tragic event and turns to Bane - like methods to gain enough power to prevent such a thing from ever happening again.

Well, it could be that Naruto is exposed to a powerful and corrupting force. This force warps his sense of justice. Deadshot's character represents a more morally gray area compared to Naruto's traditional view of right and wrong. Maybe Naruto has a series of traumatic experiences that make him question his own values. He then sees Deadshot as a model of someone who can get things done regardless of the cost, and thus begins to transform into someone like Deadshot.

Perhaps there's a powerful artifact in the Naruto world that has the ability to transform people into different superheroes from other universes. Naruto stumbles upon this artifact and, not knowing what it does, activates it and is transformed into Ant - Man. He then has to figure out how to use his new powers like shrinking, communicating with ants, and growing back to normal size while still being a ninja.

Well, it could be due to a curse. There might exist a very ancient and powerful curse that was once sealed away. But through a series of events like tomb raiding by some evil forces, the curse was unleashed. Naruto, being in the wrong place at the wrong time, got affected by it and transformed into Shadow the Hedgehog.

Perhaps there's a special artifact. In the Naruto world, there are many powerful artifacts. If one of these artifacts was somehow connected to the Pokemon world, and Naruto interacted with it, it could trigger the transformation. For example, if an ancient scroll had the power to bridge the two universes and Naruto unknowingly activated it while on a mission, his body could start to change into a Pokemon. This would not only change his physical form but also his abilities, making for a really interesting fanfic plot.
