His competitiveness might increase. In the Pokemon world, there are battles and competitions. Kurama, with his strong will, would strive to be the best trainer. He might enter Pokemon tournaments and use his strategic mind, developed from his battles in his original world, to outwit his opponents. This could make him more focused and driven in a new way.
Kurama would likely become more empathetic. As a trainer, he'd need to understand his Pokemon's feelings to train them effectively. For example, if he has a timid Squirtle, he'd have to be patient and gentle, which could soften his usually tough demon - like personality.
He might be more calm. Since the female Kurama could be a stable influence, Naruto wouldn't be as impulsive.
Naruto's optimistic personality would make him a great Pokemon trainer. He would always see the best in his Pokemon and encourage them. His never - give - up attitude would mean he wouldn't quit during tough battles or difficult training sessions.
He might become more empathetic in his human form. Since humans have a wide range of emotions and experiences, Kurama could pick up on these and become more in tune with the feelings of others compared to when he was just a fox demon.
He might become more cautious. Usually, Ash is quite bold and rushes into things. But if he's in a Team Rocket - centered fanfiction, he'd likely be more careful as he's constantly surrounded by danger. For example, he'd think twice before challenging a new Pokemon or entering an unknown area.
Let's say Danny turns into an Eevee. His adaptable nature would be taken to a new level. Eevee can evolve in many different ways, and Danny would likely be constantly thinking about his potential evolution. His personality would become more flexible, able to fit into different Pokemon groups easily. He would be more open to new experiences and relationships, and his inquisitive side would grow. He might start to see the world from a different perspective, as an Eevee has a different way of interacting with the environment compared to being a half - ghost.
If Ash were to turn into a Pokemon in a fanfic, his personality would surely be affected. He's used to being in control as a trainer, but as a Pokemon, he'd have to learn to follow others' commands or work within a group. His once outgoing and friendly nature might become more cautious. He'd have to be more aware of predators and threats. And his competitive spirit might take on a different form. Instead of competing in trainer battles, he'd be competing in Pokemon - on - Pokemon battles, which could make him more aggressive or strategic depending on the Pokemon he turns into.
His confidence might increase a great deal. Since legendary Pokemon are often seen as very powerful, Ash in his new form would feel more capable. He might become more solitary too, as some legendary Pokemon are known to be lone creatures.
Naruto is known for his optimism and that would play a great part in his Pokemon Trainer journey. When his Pokemon are feeling down after a loss, he would cheer them up. His outgoing nature would help him make friends in the Pokemon world who could give him tips on training and new places to explore. His never - say - die attitude would ensure he always tries new strategies in battles, not being afraid to experiment.
Ash's personality could shift to be more protective. Lugia is known as a guardian of the seas, and in his transformed state, Ash might feel a stronger sense of responsibility towards other Pokemon and the environment. His competitive streak, which is a big part of his normal personality, could be toned down as he now has much greater power and a different role to play in the Pokemon world. He would also have to deal with the isolation that comes with being such a powerful and different being, which could make him a bit more introverted.
Well, Ash is known for his adventurous and curious nature. In Mewtwo's body, that adventurous spirit might be redirected. Instead of running around exploring physically, he might use Mewtwo's psychic powers to explore the minds of other Pokemon or discover hidden places in the psychic realm. His personality would also become more complex as he'd have to deal with Mewtwo's memories and emotions. He'd still be the same Ash at heart, but there would be an added layer of depth and thoughtfulness, perhaps a bit of melancholy too as he'd understand Mewtwo's pain of being created for the wrong reasons. And his interactions with other Pokemon and humans would be different. He might seem more intimidating at first because of Mewtwo's appearance, but as soon as he started to communicate, his friendly and helpful Ash - like personality would show through.
