Naruto would probably choose a Pikachu first. Pikachu is energetic and has a lot of spunk, just like Naruto. They would both be full of enthusiasm and would make a great team right from the start.
In a fanfiction where Naruto becomes a Pokemon Trainer, he would bring a whole new dynamic to the Pokemon world. Naruto is used to facing tough opponents in the ninja world, and he would apply that experience in the Pokemon battles. He would be fearless in exploring new areas to find rare Pokemon. His loud and energetic personality would attract a diverse range of Pokemon. His training methods might be unorthodox, but they would likely be effective. For instance, he could use his shadow clone jutsu to train multiple Pokemon at once, just like how he uses it for his own training in the ninja world.
Naruto's outgoing and determined personality would make him a great Pokemon trainer. He is not afraid to face challenges, which is crucial in the Pokemon world. His friendly nature would also help him befriend many different Pokemon easily.
I think Bulbasaur would be a good match. Naruto has a strong connection to nature in his own world, and Bulbasaur is a nature - based Pokemon. Naruto could use his knowledge of plants from his ninja training to help Bulbasaur grow stronger.
One idea could be that Naruto discovers a strange portal that transports him to the Pokemon world. Since he has his ninja skills, he quickly adapts. He might start by befriending Pikachu, as it's one of the most iconic Pokemon. His goal could be to become a Pokemon master, using his determination from being a ninja.
Naruto would probably be really curious about Pokemon. He might try to use his ninja skills to catch them in a really acrobatic way. And with the Nine - Tails' power, he could potentially sense the strength of different Pokemon. He'd likely befriend the more friendly - looking ones first and might even try to ride on some of the bigger Pokemon like a Charizard or a Gyarados if he could manage it.
Well, he might use his ninja skills to catch Pokemon in unique ways. For example, he could use his shadow clone jutsu to surround a Pokemon and catch it more easily. His ability to endure tough situations would also make him a great Pokemon trainer in this fanfic scenario.
Well, in such a fanfiction, Ash might experience the life of a Pokemon in a very different way. He could understand their thoughts and feelings more deeply. Maybe he'd have to learn how to use Pokemon moves in his new form, which would be a really strange and exciting adventure for him.
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.
Some Naruto characters like Naruto himself would likely be very excited to see Pokemon. He might try to befriend them immediately. His friendly and outgoing nature would make him popular among the Pokemon. He could use his Rasengan technique in a non - violent way, like creating a spinning energy ball to play with Pokemon or to help them out of tough situations.
I think he could be turned into a Pikachu. Pikachu is known for its spunk and determination, which are traits Naruto also has. Plus, both are quite small but extremely powerful in their own ways. Naruto's energy could be translated into Pikachu's electric powers in an interesting way.
