Most probably, the red dragon is a central figure. Then, there could be a group of adventurers who cross paths with the red dragon. Among them, a brave knight who at first is wary of the dragon but later realizes they can work together. And also, a cunning thief in the group who has his own reasons for being involved with the dragon's story.
The red dragon itself is likely to be a main character. There might also be a young wizard or sorceress who befriends the dragon. Maybe an old sage who guides the dragon on its journey could be another main character.
Often, there are dragon riders. These characters form a special bond with the red dragon and go on adventures together. They might be brave warriors or young apprentices learning the ways of dragon riding.
One of the main characters is Will Graham, the investigator. And there's Francis Dolarhyde, the serial killer.
Sasuke could also be a main character. His relationship with Naruto might change due to Naruto having the power of the Red Dragon Emperor. Maybe he would be jealous at first, but then they could end up working together to face new threats that this power has attracted. Sakura might also be involved, perhaps she tries to help Naruto control the new power or she is worried about the changes in Naruto.
Obviously, the white dragon and the red witch are the main characters.
One possible main character could be a young and ambitious new recruit named Kai. He's eager to prove himself in the Red Dragon Kombat world and has a natural talent for combat.
Obviously, Naruto is a main character in these fanfictions. He's usually the one who gets the red eyes and the connection to the Darkness Dragon. Sasuke might also be involved, either as a rival who is intrigued by Naruto's new power or as a partner in exploring the secrets of the red eyes. Sakura could be there as well, perhaps trying to help Naruto control the power so it doesn't consume him. And sometimes, characters from other clans or villages might make an appearance, like Gaara, who might be interested in the power because of its potential threat or its possible use in protecting his own village.
The wandering rogue is another favorite. This character is full of mystery, always coming and going, and often has a shady past or a secret mission. Their interactions with other characters at the Red Dragon Inn can be filled with intrigue and danger, making for an engaging read.
The dragon and the bear are the central figures. The dragon might be a majestic, intelligent creature with its own set of powers and a complex personality. It could be wise and a bit mysterious. The bear, on the other hand, might be a more instinct - driven character, strong and protective. There could also be other supporting characters like little forest animals that look up to the dragon and the bear for protection, or an old wizard who gives them advice from time to time in their adventures.
Obviously, the beast and the dragon are the main characters. But there could also be other supporting characters like a wise old wizard who gives advice to the beast and the dragon, or a brave knight who tries to interfere in their affairs.
Well, of course, the summer dragon itself is a main character. It could be a majestic and powerful being with a kind heart. There might also be a young protagonist, perhaps a wizard - in - training who stumbles upon the dragon's existence and forms a bond with it.
