I think Gaara would be an interesting character to include. His control over sand in the Naruto world could be related to a Ground - type Pokemon he might have. He could have a very unique bond with his Pokemon. Ino could be useful too. Her mind - reading ability could potentially be used to understand the thoughts of Pokemon, helping in training and battles. And Kiba with his love for dogs could have a strong bond with a dog - like Pokemon, like Growlithe or Arcanine.
Definitely Sasuke. His skills and his drive for power would make him a formidable Pokemon trainer. He would likely focus on training strong and rare Pokemon. Hinata could also be part of the team. Her kind heart would make her great at taking care of Pokemon, and her Byakugan could potentially be used to spot hidden items or Pokemon in the wild. Rock Lee would be another good choice. His hard - working attitude would inspire his Pokemon to train hard and be strong.
Naruto himself would be a great addition. His determination and ability to never give up would translate well into being a Pokemon trainer. He could bond quickly with his Pokemon. Also, Kakashi would be good. His intelligence and strategic thinking would help in planning battles. And then there's Shikamaru. His lazy - but - brilliant mind could come up with unique battle strategies using the Pokemon's abilities.
Sakura and Bulbasaur could work well together. Sakura has her medical ninjutsu skills, and Bulbasaur can use its plant - based attacks. Sakura could heal Bulbasaur if it gets injured in battle, and Bulbasaur could protect Sakura with its vines and poisonous attacks. Also, Kakashi and Lucario would be a great match. Kakashi's intelligence and wide range of ninja techniques would pair up nicely with Lucario's ability to sense auras and its powerful combat skills.
In a Team Naruto fanfic, Naruto, Sasuke, and Sakura are the core. But don't forget Shikamaru. His intelligence can be a great asset to the team in strategic situations. Ino could also be added for her mind - related jutsu and her friendship with Sakura. Choji can bring some heart to the story with his loyalty and his unique jutsu. And of course, Kakashi, who can be the guiding force for the team, teaching them valuable lessons both in and out of combat.
If Naruto turned into a Pokemon trainer in a fanfiction, his team could consist of Pikachu because of its popularity and electric type which could symbolize Naruto's energy. Also, a Torterra as it is big and strong like Naruto's own strength. And a Greninja, which is a very ninja - like Pokemon that could match Naruto's ninja skills.
Naruto himself is obviously a must - as the main character of the fanfic. Sasuke could also be a great addition. Even if Naruto is on a solo mission, Sasuke's influence on Naruto's growth and their complex relationship can add depth to the story. Kakashi too. His wisdom and experience can be a guiding force for Naruto, even if he's not physically present with him all the time. Maybe Naruto recalls Kakashi's teachings during tough situations.
Shino would be a great character to include. He has a unique set of skills with his bugs and a calm, mysterious personality. His interactions with Kiba, who is more hot - headed, could create some interesting dynamics. Also, Hinata could be added. Her shy nature and her long - standing feelings for Naruto could add a touch of romance and emotional depth to the side - story.
A good team could be Pikachu for its popularity and electric type moves which are useful in many situations. Charizard as it's a powerful fire type. And Bulbasaur which can cover different types with its grass and poison attacks. These three are classic and can handle a lot in the story.
Gengar could be an interesting addition to the team with Hypno. Although Gengar is a Ghost/Poison - type, it has a mischievous nature that could complement Hypno's more serious demeanor. Gengar could use its sneaky abilities to set up traps for opponents, and Hypno could then use its psychic powers to finish them off when they're caught in the trap.
It's really hard to say. Team Rocket has a lot of experience in underhanded tactics and has some powerful Pokémon at their disposal. But Team Plasma has a large following and their ideological drive can give them an edge in terms of determination. It could go either way depending on the specific plot and the Pokémon each side has.
Shikamaru is a great character to focus on. His high intelligence makes for interesting plotlines. He can strategize his way out of difficult situations. For instance, in a fanfiction, he could be the key to solving a mystery that involves the entire ninja world.
Mewtwo could be an interesting addition. Given its origin as a genetically - engineered Pokemon, it can bring a whole new level of complexity to the fanfic. It's extremely powerful and its internal struggle between its power and its sense of self can be explored in the context of the rescue team's adventures.
