Who are the main characters likely to be in 'natsu turns into a dragon fanfic'?

Harry is the central figure in 'harry turns into a snake fanfic'. In addition to his closest friends, there could be some new characters introduced. For instance, an old wizard who specializes in transfiguration gone wrong. This wizard could be a hermit living on the outskirts of the wizarding world. He might have the key to understanding Harry's transformation and reversing it. And we can't forget the snakes themselves. There could be a particularly intelligent snake that befriends Harry in his new form and helps him in his journey.

Gray might show up too. He could start as a bit of a rival, not believing that Natsu can really achieve great things with this Dragon God training. But as the story progresses, he could become more of a supporter. And then there's Lucy. She might be worried about Natsu during the training, and also use her celestial spirit magic to help Natsu in some unexpected ways during his training, like summoning spirits that can provide unique challenges for Natsu to overcome.

Igneel could also play a role. Since Igneel was Natsu's adoptive dragon father, he could appear in Natsu's mind during the transformation, guiding him and giving him advice on how to handle his new dragon powers. And there could be other dragons in the story as well. They might be either friendly or hostile towards Natsu depending on their nature.

There could be her friends or family members. If it's about her turning evil due to a betrayal, those who betrayed her would be important characters. Maybe it's a close friend who she trusted completely but was secretly jealous of her.

Obviously Naruto himself is the central character. Sasuke would also likely be involved. Given their history and Sasuke's own complex relationship with Konoha, he might side with Naruto or at least be a key figure in the events. Kakashi too, as he has been Naruto's teacher and is an important figure in Konoha. He could be caught in the middle, trying to understand Naruto's motives and also trying to uphold Konoha's stability.

Obviously, Itachi as a baby would be a main character. Sasuke would also be a key character as Itachi's brother. Their relationship would be very different now that Itachi is a baby. Naruto could also be involved, perhaps being curious about this strange transformation and wanting to help out in some way.

Obviously, Naruto would be one of the main characters. He's the protagonist of the Naruto series, so it's very likely he'll play a central role in the fanfic. Sasuke could also be a main character as he often has his own story arcs that intersect with Naruto's. And maybe Sakura too, since she's part of the main trio. There might also be some new characters introduced specifically for this fanfic related to the Dragon Blade, like a mysterious ninja who has a connection to the blade's history.

Gray would be one of the main characters to interact with Natsu. Their friendly rivalry is well - known in Fairy Tail. Makarov, as the guild master, would also have an important role in interacting with Natsu. He might give Natsu some important tasks or just have a grandfatherly chat with him about his return.

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.

In this 'natsu turns into a dragon fanfic', a great plotline could be that Natsu's dragon form is different from the typical dragons. His friends, like Lucy, Gray, and Erza, try to find a way to reverse the transformation at first. But as they see the potential in his new form to fight a greater evil, they change their minds and instead help him master his dragon powers. This could involve a series of adventures where Natsu has to learn to fly, breathe different types of dragon fire, and communicate with other dragon - like creatures.
