Another possible character could be Kakashi. As their sensei, he could train Naruto and Souna together. He would guide them in developing their ninja skills and also give them advice on how to deal with the challenges they face as brothers. Kakashi's wisdom and experience would be crucial in their growth, and his presence could add more depth to the story, especially when it comes to the relationship between Naruto and Souna.
It could be about Naruto having a special bond with Souna as his brother. Maybe they go on adventures together, face challenges in the ninja world side by side, and Naruto uses his skills to protect Souna from various threats.
In some fanfics, the twin brother might have a special bond with a female character. For instance, Sakura could be intrigued by the twin brother's different personality compared to Naruto. She might initially be confused about her feelings towards both brothers, which could add a romantic sub - plot to the story along with all the ninja action.
Obviously, Naruto and Sona's brother would be the main characters. Naruto with his energetic and determined personality, always ready to take on any challenge. And Sona's brother, who could have his own unique traits, maybe he's more reserved but very intelligent.
Well, Naruto is surely a main character. The brother is the other main focus. The brother could have a distinct personality. He might be more introverted compared to Naruto's outgoing nature. Other characters like Jiraiya could also be part of the story. Jiraiya could be the one who discovers the existence of Naruto's brother and helps Naruto understand his new family connection. There could also be antagonists in the story who target Naruto and his brother for some reason, adding more drama to the fanfiction.
Obviously, Naruto and Kushina would be the main characters since it's about Naruto being Kushina's brother. But there could also be other important characters. Minato might be a significant character as he was Kushina's husband. Also, characters like Jiraiya could be involved, as he was Naruto's teacher and had a connection to Minato. And then there are Naruto's friends like Sasuke and Sakura, who could interact with Naruto in this new family - centered scenario.
In addition to Naruto and Superboy, there could be other characters from both universes. Maybe some of Naruto's friends like Sasuke or Sakura could be involved. From Superboy's side, perhaps his friends or mentors from the superhero world might make an appearance. They could play important roles in the story, either helping or hindering the relationship between Naruto and Superboy.
The main character is Naruto for sure. As for the orphans, they could be a diverse group with different personalities and backstories. Some might be shy, some brave. And there could be an older orphan who becomes Naruto's right - hand in looking after the others. Also, if there are any antagonists, they could be people who try to take advantage of the orphanage or its resources, and Naruto has to stop them.
There could also be other characters from the Naruto series like Sasuke, Sakura, and Kakashi. They might interact with Naruto and Koneko in different ways. For instance, Sasuke could be initially suspicious of Koneko but later become her ally. Sakura could help Koneko with her medical ninjutsu training if Koneko shows an interest. And Kakashi could be the one to guide them in some difficult missions or training sessions.
The two main characters are Naruto and Natsu. Naruto has his friends like Sasuke and Sakura in his world, but in this fanfiction, his connection with Natsu is what matters most. Natsu also has his Fairy Tail guild mates, but here, his newfound brother Naruto is the key relationship. Their interactions, their differences in powers and personalities, and how they support each other would be explored through their characters.
Obviously, Naruto is one of the main characters. And then there's his new brother. Depending on the fanfiction, there might also be other well - known Naruto characters like Sasuke or Sakura. They could be involved in the story in different ways, like being friends or foes to the new brother.
