Naruto's character could develop a new sense of curiosity. Summoning Pokemon would expose him to a whole new world of creatures and powers. He might become more adaptable as he has to learn how to work with Pokemon, which have different personalities and abilities compared to the summons he's used to in his own world.
Naruto might also become more empathetic. Pokemon are often shown to have strong emotions and bonds with their trainers. As he forms relationships with the Pokemon he summons, he'll learn to understand their feelings better. This could translate into him being more in tune with the emotions of those around him in his own ninja world, whether it's his friends, allies, or even his enemies. He could start to see the similarities between the Pokemon and the people he knows, leading to a more well - rounded and understanding character.
Naruto's character would become more in tune with nature. Dragons are often seen as symbols of nature's power. By having a dragon summon, he would start to understand the delicate balance of nature better. He might also gain a new perspective on his own power and how it fits into the larger scheme of things. This could lead to him being more empathetic towards other creatures and more protective of the natural world around him.
If Naruto got a unique summon contract in fanfiction, his relationships could change. His friends might be in awe of his new power. But some might also be a bit jealous. Naruto would have to learn to handle these new dynamics. On the battlefield, he'd be more of a leader. His summons could act as his troops, and he'd need to direct them, which would develop his leadership skills.
The character might start off as a shy and unconfident Pokemon trainer. Due to being neglected for his Naruto - related interests, he would gradually become more determined. He would learn from Naruto's never - give - up attitude and start to stand up for his unique training methods.
Naruto might become more serious. Deadshot is a very serious and focused character. So Naruto could lose some of his goofy and carefree nature and become more calculating in his actions.
Naruto might become more cautious. Dealing with the Daleks, who are extremely dangerous and unpredictable, would force him to think before acting. His normal brashness might be toned down a bit.
Naruto's character would likely become more calm and introspective. He'd focus more on inner peace rather than external battles.
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.
Naruto's character would likely become more confident. With a family structure provided by Mikoto, he would feel more secure. He might also become more mature as he is exposed to the Uchiha way of life. For example, he could learn discipline and patience more quickly. His understanding of the ninja world would expand as he learns from Mikoto about different clans and their relationships.
Naruto's character would likely become more withdrawn at first. The sudden change to being a frost demon would make him feel different from his friends. But as he learns to control his new powers, he'd become more confident. His sense of justice would still be there, but it might be tempered with the knowledge of his new, potentially dangerous abilities.
Naruto's character would likely become more complex. He might develop a harsher edge due to Akainu's influence, but still retain his core kindness.
