One possibility could be Boruto as a new - age Naruto - like character. Sarada, with her Sharingan and Uchiha heritage, could be another member, similar to Sasuke. And for the third member, maybe a new character like a young ninja from a small and previously unrecognized clan who has a unique chakra ability. This new character could bring in fresh dynamics to the team.
The new member could be really laid - back. They don't get stressed easily during missions, which sometimes annoys Sasuke who is always so serious. For example, when they are facing a tough enemy, the new member might crack a joke to lighten the mood.
Well, a cool plot for a 'Naruto New Team 7 Fanfiction' might be that the team gets transported to a different dimension. In this dimension, the rules of chakra are all messed up. They have to adapt quickly and find a way back home. Along the way, they meet alternate versions of their predecessors. This would be really interesting as they could learn from these alternate versions and gain new skills. Also, a plot where the new Team 7 has to protect a sacred artifact that is coveted by various criminal organizations in the ninja world would be exciting. They would have to constantly be on guard and use their teamwork to keep it safe.
Naruto faces a whole new set of challenges. Firstly, the ANBU has a strict code of conduct which he needs to adapt to. The missions are often solo or with very small teams, so he has to rely more on himself rather than his comrades like in Team 7. Also, the enemies he faces in ANBU are often more powerful and cunning. He has to keep his identity a secret, which is a big change from his more open - natured role in Team 7.
A new character could be an old hermit who lives in a hidden cave in the mountains. This hermit has mastered a unique form of chakra control that allows him to manipulate the elements in ways not seen before. He takes an interest in Team 7 and decides to train them. He teaches Naruto how to combine his wind chakra with the earth beneath him to create powerful tornado - like attacks. For Sasuke, he shows how to infuse his fire chakra with lightning to make it more potent. And for Sakura, he helps her develop a new form of medical ninjutsu that can heal internal injuries more quickly.
One idea could be that the new member is from a far - off village that has a unique jutsu. For example, they could have a jutsu that allows them to control plants, which would add an interesting dynamic to Team 7's battles. The plot could involve the team initially being skeptical of this new member, especially Naruto who is used to his core group. But as they go on missions together, they start to see the value of the new member's skills. Maybe the new member has a dark past related to Orochimaru, and Team 7 has to help them overcome it while also dealing with Orochimaru's possible return.
The team dynamics would be quite unique. There would be a lot of self - competition. Each Naruto would be trying to outdo the other in terms of strength, speed, and ninjutsu. But at the same time, they would also understand each other deeply since they are the same person. They might have an unspoken agreement to push each other to be better.
It could be some of the younger ninjas from the village who look up to Naruto. Maybe a young genin who has a special ability with earth jutsu, and another who is really good at stealth but lacks confidence. Naruto would then help them grow.
Kurenai might be a good sensei for Naruto's different team. Her expertise in genjutsu would be valuable. She could help the team develop their skills in this area, especially if the new team members have some potential in genjutsu. Kurenai is also very perceptive, which would be great for guiding Naruto and his new teammates through difficult situations.
The scenario where Team 8 saves Team 7 instead would be quite interesting. It could introduce new conflicts and resolutions, and potentially reveal hidden strengths of Team 8 that weren't previously showcased.
