How about a team with Kiba, Neji, and Karin? Kiba with Akamaru has great tracking abilities, Neji can use his Byakugan for perception and defense, and Karin has her unique sensing abilities which could be useful in various missions.
A third plot might be an all - female alternate team with Hinata, Ino, and Temari. They are tasked with protecting a princess from another land during her visit to Konoha. Hinata's gentle fist and Byakugan, Ino's mind - transfer jutsu, and Temari's wind - based attacks would be used to fend off assassins and ensure the princess's safety.
First, come up with a unique concept for your alternate universe. It could be something like a world where ninjas use modern technology. Then, think about how the characters will be different. For Naruto, maybe he's not an orphan or he has different abilities. Next, plan out the plot. You can start with a small change in the Naruto universe and build on it. For instance, if the Uchiha clan was never massacred, how would that change the relationships and the overall story?
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.
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.
Sakura would be heartbroken. She'd likely spend hours upon hours by Naruto's side, trying to jog his memory with stories of their adventures together. She might even get a bit overbearing in her attempts. Sasuke, who has his own complex relationship with Naruto, would be conflicted. He'd see Naruto's forgetfulness as a sign of weakness at first but then realize the importance of their bond. Kakashi, being the experienced leader, would start by observing Naruto carefully to see exactly how much he has forgotten and then start a systematic process of helping him remember.
Power exploration is also a big theme. Different dimensions may have different power systems. So, Naruto has to learn about new types of chakra or abilities. In some fanfictions, he might even combine his original powers with the new ones from the alternate dimension. This can lead to really cool battles and power - up moments. Another common theme is friendship. Even in alternate dimensions, Naruto still values his friends. He might meet alternate versions of his friends or make new ones. The relationships he forms and how they help him through difficult situations are often explored in these fanfictions. It adds an emotional depth to the stories.
In alternate naruto fanfiction, Hinata can be extremely popular. Writers might give her a more assertive role. For example, in some stories, she could be a powerful leader instead of the shy girl in the original series. Also, Itachi is a popular choice. His complex character and the mystery surrounding his actions make him ripe for exploration in alternate storylines, such as what if he didn't have to carry out the massacre of the Uchiha clan.
In some alternate naruto fanfiction, there might be a scenario where Naruto was raised in a different village. Imagine if he was brought up in the Sand Village. His personality and skills would likely develop differently, influenced by the Sand's culture and fighting styles. He might form different relationships and have different goals compared to his original story.
