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.
In the fanfiction, the hawk summon might expose Naruto to a different side of the ninja world. This could make him more empathetic towards other creatures and shinobi who have unique summons. It could also make him more responsible as he has a new powerful ally to take care of.
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's character would likely become more stoic. Vergil is known for his calm and collected demeanor, so Naruto might start to suppress his more exuberant emotions. He could become more calculating in battles, thinking several steps ahead like Vergil does when facing his enemies.
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.
Definitely Pikachu. Since Naruto is often in need of a quick and agile ally, Pikachu's speed and electric attacks would be very useful. Plus, Pikachu's cute appearance but powerful abilities would create an interesting contrast with Naruto's ninja style.
His character might be more hardened. Growing up with Yahiko, he'd be exposed to the harsher side of the ninja world earlier. So he'd be less likely to trust blindly.
