A young dragon - trainer. This person could have unique knowledge about dragons that even the Red Dragon doesn't know. They could help the Red Dragon unlock new powers or skills.
A mysterious oracle. This character could predict future events related to the Red Dragon and Yona's journey. Their prophecies could drive the story forward and create new conflicts.
A young dragon slayer from a far - off land who has a unique magic related to the elements that haven't been seen in Fairy Tail before. Maybe his magic is connected to some aspect of the Dragon Cry.
A character with the ability to transform into different elements like fire, water, or earth. This would add a new dynamic to the battles. Another could be a small, alien creature that has the power to control the minds of others, creating chaos among the heroes. There could also be a warrior from a lost civilization in the Macho Universe who has a unique fighting style that combines swordsmanship and Ki blasts.
A group of nomadic mice. They have different skills and traditions compared to the Redwall mice. Their arrival at the abbey could cause some cultural clashes at first, but eventually, they could learn from each other and contribute to the abbey's growth. This would add more diversity to the characters in the fanfiction.
A young stargazer from Earth could be a new character. This character could be someone who has always been fascinated by the stars and dreams of traveling to other planets. When the Little Prince lands on Earth again, they meet and the stargazer becomes his guide on Earth, showing him all the new things that have happened since his last visit. Another potential character could be a talking moonbeam. It could offer the Little Prince advice and wisdom, as well as some magical abilities to help him on his journey.
A new character could be a therapist who has a unique approach to helping the main character. This therapist could introduce new ideas and methods of healing that the main character hasn't encountered before.
A healer from a far - off land could be an interesting addition. This character could bring in new knowledge of magic and medicine that the existing characters are unaware of. Maybe they have a special connection to nature that allows them to heal in ways not seen before in the story.
A young Martian inventor could be a great addition. This character could create unique gadgets and machines that help the protagonists in their adventures. For example, a flying device that can travel at high speeds across Mars.
A mysterious traveler passing through the town could be a new character. This person has seen many strange things in their travels and is not afraid of Edward. In fact, they see his potential and encourage him to leave the town and see the world.
A healer character could be added. This healer could be the one who discovers a hidden power within the apprentice that could change the course of their journey. Another potential character could be a mysterious traveler. This traveler has seen many different worlds and has knowledge that could either help or hinder the apprentice.
Another plot idea is a story where the Red Dragon has to face a new and powerful enemy alone, without Yona and the other dragons by his side. It could show his individual strength and his ability to strategize in difficult situations.
