The main characters are Naruto and Natsu, but it's possible that some original characters could be created for this fanfiction. Maybe a character who has the power to bridge the two worlds of ninjas and wizards. However, Naruto and Natsu would still be at the center of the story, with their relationship and adventures being the main focus.
In addition to Naruto and Natsu, there could also be other important characters. For example, Sasuke from Naruto's world might make an appearance if there's a connection between the two worlds. From Fairy Tail, characters like Lucy could also be involved as she often teams up with Natsu. They could all interact in various ways, depending on the plot of the fanfiction.
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.
Well, the two brothers would obviously be the main characters. Their names might be Naruto and Natsu, though it's a fanfic so the author could give them some unique twists to their personalities compared to the original Naruto series.
Obviously, Natsu is one of the main characters. He is a powerful dragon - slayer with a fiery personality. The fairies also play major roles. For example, Lucy, who is a celestial wizard and Natsu's friend. She often provides support with her summoned spirits. Happy, the blue flying cat, is also an important character. He is Natsu's sidekick and often adds some comical elements to the story.
Lucy could be a main character. Since she's often by Natsu's side, she would likely be deeply involved in his recovery. She could use her celestial spirit magic to try and protect him while he's injured or search for a way to heal him.
Happy, Natsu's flying cat companion, would definitely be a main character. He would be there to provide comic relief as always, but also be a source of emotional support for Natsu during his transformation into a dragon god. Erza might also be a prominent character. With her strong leadership skills and powerful magic, she could be guiding the guild during the times when Natsu is still coming to terms with his powers and the changes it brings to the guild.
Definitely Ruby Rose. Since she's the main protagonist in RWBY, it's likely that Natsu would cross paths with her first. Their personalities are quite different, with Ruby being more innocent and Natsu being more brash, so their interactions would be interesting.
There could also be some new characters introduced specifically for this fanfiction. For instance, an ancient dragon who knows all about Natsu's true nature and acts as a mentor to him. This dragon could have a complex backstory and motives, and its interactions with Natsu and the other Fairy Tail members would be a major part of the story.
The main characters are Erza and Natsu. Erza is often portrayed as a strong and disciplined mage, while Natsu is a hot - headed and powerful dragon slayer.
The main characters are Natsu and Juvia, of course. Natsu is a fiery and passionate character, while Juvia is more emotional and often has a melancholic side.
Obviously, Natsu and Mirajane are the main characters. Natsu, with his red - haired, energetic self, brings his unique charm and his powerful fire magic. Mirajane, with her white hair and her ability to transform into different forms, adds her own flavor to the story. And the baby, which is new to their lives, serves as a catalyst for new adventures and character development.
