In a fanfiction where Naruto becomes mute, it would have a profound effect on his growth as a character. His journey to become Hokage would be different. He would have to find alternative ways to lead and communicate with the village. This could involve developing a more refined sign language or telepathic abilities perhaps. Also, his relationship with his mentor figures like Iruka and Kakashi would change. They would need to adapt to his new condition and help him find new ways to express himself.
One way the story could develop is that Naruto would have to rely more on his other senses like smell and hearing. His friends would also have to find new ways to communicate with him. For example, they might use sign language if Naruto could feel the movements. His ninja skills would also change. Instead of relying on visual cues for attacks, he'd depend on sound and vibrations.
If Naruto were born mute in fanfiction, his story would be drastically different. He might rely more on body language and written notes to communicate. His relationships would also change. For example, with Iruka, Iruka might have to be more patient and find different ways to teach him. Naruto would probably face more bullying not just for being the Jinchuriki but also for his inability to speak. His journey to become Hokage would be filled with more challenges as he has to overcome the communication barrier.
If Kushina and Minato abandoned Naruto in fanfiction, it would completely change the Naruto's character development. Naruto grew up lonely and seeking recognition because he was an orphan. Without their abandonment, he might have had a very different personality, perhaps more confident from the start. Also, the relationships in the village would be different. For example, Iruka might not have had the same special bond with Naruto as he did in the original story.
The impact would be significant. In the Naruto universe, a baby from Naruto and Sakura would symbolize a new hope. Since Naruto is a hero and Sakura is a strong kunoichi, their child would be expected to carry on their legacies. Politically, it could strengthen the bonds between different villages. If the baby shows great potential, other villages might try to form alliances through marriage or other means in the future. Emotionally, it would be a big deal for their friends like Sasuke, who might see it as a sign of a new era of peace and stability.
The Naruto storyline would be unrecognizable. In the original, Naruto is a hero. But as a serial killer, he might start targeting those he once protected. The Hidden Leaf Village would be in chaos. The villagers who once saw him as a hero would now be living in fear. His ninja skills, which were used for good, would be turned to evil. He could use his shadow clone jutsu to deceive and then attack his victims. It would also make the other ninja villages view the Leaf Village differently, perhaps as a place that breeds killers instead of heroes.
It could change the power dynamics in the village. For example, if the child is seen as having great potential due to Hinata and Sasuke's lineages, there could be different factions vying for influence over the unborn child. This would add a new layer of political intrigue to the Naruto universe.
It could inspire them to add more complex power systems. Just like Naruto has different chakra natures, RWBY could think about more diverse ways of using their auras. For example, they might consider something like elemental auras.
Well, Naruto could gain dragon - like powers such as breathing fire or flying. His ninja skills combined with dragon abilities would make him nearly unstoppable. Maybe he'd use his new form to protect Konoha from a greater threat than ever before, like an army of powerful demons. He could also use his dragon form to travel long distances quickly to gather information or allies.
Naruto could adapt by using his strong willpower. He has faced many challenges in his own world, so he would rely on that experience. He might start by learning about Shao Kahn's powers and the politics of Outworld. His ability to make friends quickly could also help him. He could form alliances with some of the more reasonable characters in Outworld who were previously afraid of Shao Kahn.
One possible plot could be that Naruto is exposed to some ancient and dark magic during a mission. This magic slowly transforms him into a Youkai. As he turns, he starts to struggle with his new instincts and powers. His friends initially don't recognize him and think he's a new threat. Naruto has to find a way to control his Youkai side and convince his friends that he's still himself.
