Sasuke could be one of his teammates. Despite their past differences, they could put aside their rivalry on the baseball field and use their respective skills to the team's advantage. Sasuke's speed and precision would be great assets.
Shikamaru could also be on the team. His strategic mind would be useful for planning plays and outsmarting the opposing teams. He could analyze the opponents' weaknesses and come up with winning strategies during the baseball games.
Rock Lee would be a great teammate. His high energy and physical strength could be used for powerful batting and fielding. He could also inspire the team with his positive and hard - working attitude.
For Naruto's soccer team in this fanfiction, I think Shikamaru would be a great teammate. His strategic mind could come up with amazing game plans. Choji might also be on the team, using his large size to block opponents or gain possession of the ball. Ino could use her mind - transfer jutsu in a non - harmful way to communicate with her teammates during the game and anticipate the opponents' moves. And of course, there's always the possibility of Lee being on the team. His extreme physical training would make him a fast and strong player on the field.
Maybe Naruto discovers baseball in the Hidden Leaf Village and decides to form a team with his ninja friends. They could use their ninja skills in unique ways on the baseball field, like using shadow clones to confuse the opposing team.
His favorite could also be Jackie Robinson. Since Naruto has always fought against discrimination in his own world, he might admire Jackie Robinson for breaking the color barrier in baseball. Naruto would see Jackie as a hero, not just in baseball but also as someone who overcame great odds and prejudice.
Kakashi could also be an opponent. He would be a very challenging one, using his vast knowledge and experience. He might teach Naruto some chess strategies during the game, just like he teaches him ninja techniques.
It could be Sasuke. Sasuke is highly intelligent and has a great strategic mind. He would approach shogi with the same intensity as he does his ninja battles. He would be able to analyze Naruto's moves quickly and counter them effectively.
Sakura could be one of his teammates. She has her medical ninjutsu skills which would be useful in treating injuries during missions. Also, her super strength could come in handy in combat situations.
Another teammate often included in fanfiction is Kakashi. Some fanfictions might create scenarios where Itachi and Kakashi interact during missions or even in their off - time. It could be interesting to see how their different skills and personalities clash or complement each other. For example, Kakashi's laid - back attitude contrasted with Itachi's more serious and reserved nature.
Shikamaru is an obvious choice. Shikamaru is a master strategist, and shogi would be right up his alley. He would give Naruto a really hard time with his complex strategies and deep understanding of the game.
Sasuke could be a great opponent. Their rivalry could translate well into a game of chess. Sasuke's calculating nature and sharp intellect would make him a formidable adversary for Naruto, and their games could be intense battles of wits.
In this fanfiction, Naruto might befriend Klein. Klein is an easy - going character in SAO, and his friendly nature could make him a good match for Naruto. Another potential ally could be Sinon. Given her excellent marksmanship skills, she could complement Naruto's more close - range combat style. They could work together in battles and help each other out in different quests within the game.
