Naruto's character would likely become more aggressive. Yujiro is a very aggressive character, and Naruto might start to show similar traits. He could be quicker to anger and more assertive in his actions.
Naruto's character would become more unpredictable. His usual straightforward and determined self would be mixed with Deadpool's randomness. He might start taking risks he wouldn't normally take, just for the fun of it.
If Naruto were to act like Yujiro in a fanfiction, it would change his relationships too. He would no longer be the overly - friendly Naruto we know. He might become more aloof and selective with his friendships. His interactions with Sasuke could be different. Instead of constantly trying to bring Sasuke back with kindness, he might use a more forceful and intimidating approach, just like Yujiro would deal with those who oppose him.
His character could become more resourceful. He'd have to make do with what he has in the wild. He'd learn to use natural materials to build his traps and shelter. This new way of life might also make him more empathetic towards animals and the environment. He'd realize that every life is precious, and he'd only take what he needs to survive. This could lead to a more mellow and philosophical Naruto, who sees the world from a different perspective than the brash and eager - to - prove - himself Naruto we know from the original series.
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.
Sakura would be worried sick. She'd try to figure out what happened to Naruto to make him act this way. She might try to talk to him, use her medical ninjutsu to check if he's under some kind of genjutsu or has some other problem. She'd be very vocal about her concerns and would try to get the other villagers to help bring Naruto back to his normal self.
Well, he might become more protective. Just like Whitebeard who was extremely protective of his crew, Naruto could start showing that same level of protectiveness towards his friends and the village. He might be more willing to use his power to shield them from any harm.
Well, if Naruto acts like an Uchiha in fanfiction, his character development could be very different. Uchihas are often known for their brooding and more introverted natures compared to Naruto's original outgoing self. He might become more focused on power and revenge, like some of the Uchihas. His relationships would also change. For example, his bond with Sasuke might be less about rivalry and more about a shared Uchiha - like identity. He could also start to use Sharingan - like abilities, which would change the way he approaches battles and his overall growth as a ninja.
