He might develop a more complex view of the world. With two bijuu, he'd be in the center of a lot more attention, both good and bad. This would make him more aware of the politics between villages. He'd also have to learn to handle different types of chakra, which could lead to new techniques and a deeper understanding of ninjutsu in general. His relationships with his friends could also change. Some might be in awe of his new power, while others might be worried about him getting corrupted by it.
Naruto's character would grow in terms of self - discovery. He'd have to figure out how to coexist with two powerful entities inside him. This would involve exploring his own identity more deeply. He may also become more empathetic towards the bijuu, understanding their pasts and motives better. As he tries to balance their powers, he would become a more mature and strategic ninja, using his new abilities not just for fighting, but also for protecting the balance in the ninja world.
In this fanfiction, Naruto's character development would be complex. Growing up with a Jinchuuriki, he would have a deeper understanding of the power within. He might not be as loud and brash as in the original. Instead, he could be more of a silent observer at first. As he grows, he would gradually show his leadership skills in a different way. He would use his knowledge of the Jinchuuriki and their power to inspire others, and also be more diplomatic in dealing with different clans and villages, as he has seen the consequences of being an outcast through the Jinchuuriki's experience.
A plot twist might involve the other villages' reactions. When they find out Naruto is the jinchuuriki of two bijuu, they could either see him as a greater threat or try to ally with Konoha. Maybe some villages would send spies or assassins to either capture Naruto or steal the power of the bijuu from him. This would create a lot of political intrigue and danger for Naruto and his friends.
He might develop more self - reliance. Without relying on the power of the tailed beast, Naruto has to work harder on his own training. He could become more strategic in battles as he doesn't have the brute force of the jinchuuriki to fall back on.
Naruto's character development as the Sanbi Jinchuuriki in a fanfic would be complex. He'd have to face new insecurities. The Sanbi might have a different influence on his emotions compared to the Kyuubi. He could become more strategic in his battles, as the Sanbi's powers might require more finesse. Also, his relationships with his peers would shift. Some might envy his new power, while others might be afraid of it, forcing Naruto to reevaluate his place among them.
In a fanfic where Naruto uses the Force, his development would be interesting. He might start to use the Force to better understand his opponents. For example, he could use it to predict their moves, similar to his ability to sense chakra. His ninjutsu training could be combined with the Force training. Maybe he'd learn to levitate himself or objects using the Force, which would add a new dimension to his combat style. And his understanding of the world around him would change as he discovers the power of the Force.
In this scenario, Naruto would experience a significant shift in his character. He would be forced to make tough decisions. For example, he would have to choose between the village's rules and his loyalty to the fem Kyuubi. This would make him more mature. His relationship with the fem Kyuubi would also bring out a more protective side of him. He would have to learn how to control the power she represents in a new way. Additionally, being outside the village would expose him to different cultures and ways of life, which would shape his beliefs and values. All these factors combined would transform Naruto into a very different kind of shinobi compared to the one we know in the original series.
As the Ten - Tails Jinchuuriki in fanfiction, Naruto's character development could be quite complex. He would have to learn to control this new and overwhelming power. This would require a great deal of self - discipline. His sense of responsibility would also grow as he realizes the potential destruction his power could cause if misused. He might become more withdrawn at first, trying to figure out how to handle this new part of himself, but eventually, he would emerge as an even more reliable and powerful hero.
Naruto might become more confident, but also more cautious. The power of the Juubi is immense, and he would need to be careful not to let it corrupt him. He could also become more of a leader, as his power would make him a key figure in the ninja world.
Naruto would likely become more confident in his ability to protect others. Saving Kurenai from Asuma would show him that he can handle complex and dangerous situations within the village. His reputation would also grow, and he might gain more respect from the older generation like Kurenai.
Their relationship might start off rocky. Gaara has been through a lot of pain and isolation, while Naruto was always seeking acceptance. But as they realize they are Jinchuuriki brothers, they could gradually grow closer. Naruto's friendly nature could break through Gaara's cold exterior. They would start to trust each other, sharing their experiences of living with the tailed beasts inside them.
