Sarada is a very popular character to include. She has her own goals of becoming Hokage and her Sharingan gives her a lot of potential for interesting storylines. For example, she could be on a mission to unlock new powers of her Sharingan.
Shikadai is another one. His intelligence and laziness create a fun dynamic. A fanfiction could focus on him coming up with a brilliant battle strategy against a new and powerful enemy, but having to overcome his own reluctance to get involved in the first place.
Obviously Naruto and Boruto themselves are very popular. But characters like Hinata, Naruto's wife, also add a lot to the family dynamic in fanfiction. Sasuke is another one, as he has a complex relationship with Naruto and can be involved in the story in many ways. For example, he could be a mentor to Boruto. And of course, the older generation like Kakashi can also be included to give some wisdom and guidance to the family.
One great 'Boruto Naruto Next Generation' fanfic is 'The Legacy Continues'. It focuses on Boruto's journey to discover his own ninja way, separate from his father's shadow. The story has well - developed original characters that interact realistically with the established Naruto universe characters.
Boruto is an obvious choice. He is the main character of the new generation. Sarada, with her Sharingan and strong - willed personality, is also very popular. Mitsuki, being Orochimaru's creation, has a lot of mystery around him and is a great character to include. Then there's also Cho - Cho, who provides some comedic relief while also being a capable kunoichi.
One idea could be Boruto going on a solo mission to a far - off land that has a unique chakra - based mystery. Maybe there's an ancient power there that's starting to awaken and Boruto has to figure out how to stop it from being misused.
Definitely Sasuke. His relationship with Naruto is so important in the original story, and when it comes to a fanfiction with kid Naruto and Boruto, Sasuke can act as a mentor or a challenging rival for both of them. Another great character is Hinata. She has a special connection to Naruto, and in a fanfiction, she could play a role in guiding Boruto or providing support to kid Naruto in a new situation.
Obviously Naruto and Boruto themselves are the most essential characters. But Sasuke can also be a great addition. His relationship with Naruto is well - known, and his skills and experience can add depth to the story. He could act as a mentor to Boruto as well.
A unique plot makes a 'Boruto Naruto Next Generation' fanfic stand out. For example, if it takes the story in a direction not explored in the official series, like a different type of villain or a new power system.
It's decent. The anime keeps many elements from the manga but adds some filler episodes and plot tweaks.
It has some connections and similarities, but also brings new elements and storylines.
Obviously, Bolt himself is a central character. His friends like Sarada, the daughter of Sasuke and Sakura, often appear. Naruto and Hinata also show up as Bolt's parents, guiding him or being a source of his inspiration or conflict.
