Who are the likely characters in the 'kobayashi becomes a dragon fanfic'?

Well, it could be about Kobayashi suddenly finding herself in a situation where she starts to transform into a dragon. Maybe it's due to a magic spell gone wrong. She then has to deal with newfound powers and instincts.

Obviously, Chell is the main character. There could also be other characters from the original story that interact with Chell during her transformation into a core. Maybe some mentor - like figures who guide her through the process, or antagonists who try to stop her from achieving this new status.

Obviously Percy himself. Also, Annabeth would probably be there as his girlfriend. Grover, his satyr friend, might also make an appearance. And the gods, like Poseidon, Percy's father, would surely play a role, either guiding Percy or testing him on his path to godhood.

Obviously, Rarity herself is the central character. Her friends from the Mane Six, like Twilight Sparkle, who could help her understand the magic involved in becoming an alicorn. Also, Spike might be there, as he's always around Twilight and could play a role in Rarity's journey, perhaps by providing some useful information he's found in his library duties.

Obviously, Natsu would be the main character as he is the one turning into a dragon. His friends like Lucy, Gray, and Erza are also likely to be main characters. They would play important roles in either helping Natsu deal with his transformation or being affected by it 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.

There could be new characters introduced, like old family retainers of the noble family Harry is now part of. Maybe an old wizard who serves as an advisor to Harry on matters of the lordship. And of course, some antagonists such as rival lords or wizards who don't want Harry to gain too much power.

Tohru is a very prominent character. She is strong - willed and has a deep affection for Kobayashi. Her attempts to blend into human society while still being a dragon lead to many interesting scenarios. Kobayashi is the ordinary human who gets caught up in this extraordinary situation. She is often the voice of reason. Kanna, on the other hand, is cute and innocent. She is like a child in many ways and her interactions with the other characters are really sweet.

In addition to Natsu's Fairy Tail friends, there could be some dragon characters. Maybe Igneel, Natsu's adoptive father dragon, could play a role, perhaps in the form of a spirit or a memory guiding Natsu. There might also be other powerful dragons who are either allies or enemies depending on how they view Natsu's transformation into the Fire Dragon King.
