Sasuke is very likely to be involved. He has a close relationship with Naruto and is also an important figure in Boruto's life. His skills and knowledge could be crucial in any adventure or situation that Naruto and Boruto find themselves in. Another character could be Hinata. As Naruto's wife, she would surely be concerned about any strange events involving Naruto. And for Boruto, she is his mother, so she would play a role in any family - related or village - threatening situations.
Physically, Naruto can use his Rasengan or other powerful jutsus to fend off enemies attacking Boruto. His combat skills are top - notch, and he won't hesitate to engage in battle to keep Boruto safe.
The most popular characters in 'Boruto meets Naruto fanfiction' are Naruto and Boruto, as they are the main focus of the concept. However, characters like Jiraiya can also be very popular. His connection to Naruto and his own legendary status add depth to the fanfiction. Shikamaru is another character that fans like to see in these stories. His intelligence and laid - back attitude can create some interesting interactions with the main characters.
The Boruto characters would probably have a range of reactions. Characters like Sarada might be interested in fanfictions that explore her mother's story more deeply. However, they also might be a bit confused by some of the more out - there concepts in fanfiction. Fanfiction often takes creative liberties that might not align with the official story, and the Boruto characters would have to adjust to that when reading.
Often, they are shown as more mature and experienced. Naruto is still the strong Hokage but also a loving father. Hinata has become more confident in her role as Naruto's wife and as a mother. For example, she might be more assertive in decision - making for the family.
They might be quite surprised. Some characters like Naruto himself would probably be amused to see the different interpretations of his son's adventures in fanfiction. He might find it interesting how fans imagine Boruto's growth and the relationships within the new generation.
Naruto would likely be excited. He loves his son so much that seeing different stories about Boruto would be like seeing different potential futures for him. He might even get some inspiration from the fanfiction to give Boruto some advice in real life.
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.
