An outcast little monster could be introduced. This character has been shunned by the rest of the community for being different. Maurice befriends this outcast, and together they try to change the perception of the other little monsters. It could be a story of acceptance and friendship that shows the power of unity even among those who are different.
A wise old little monster could be added. This character could act as a mentor to Maurice, guiding him with ancient knowledge and wisdom. For example, when Maurice is faced with a difficult decision, the old monster can offer insights based on the history of the little monsters.
A witch character would be great. She could either be a helpful mentor to Gregory, teaching him magic spells, or a mischievous troublemaker who constantly plays pranks on him.
You could add a ghost dog as a new character. It could be Lenore's loyal companion, following her everywhere she goes in the afterlife. The dog could have a backstory of its own, like it was a lost puppy in the living world and now it has found a friend in Lenore.
One idea could be that Maurice discovers a hidden power within himself. Maybe he can communicate with a long - lost species of little monsters. This would lead to an adventure where he has to convince the other little monsters to trust this new discovery and use it to their advantage.
A wise old owl could be added. It could give advice to the little white horse. Also, a mischievous fox that sometimes gets the horse into trouble but also helps it out of tight spots.
A young demigod who has the power to communicate with the spirits of the monsters. This character could help Percy understand the motives of the monsters better and maybe find non - violent solutions to some of the conflicts.
Hermione would be a great addition. She could use her vast knowledge of magic and research skills to help Harry and Buckbeak in their adventures. For example, if they were on a quest to find a rare magical herb to cure Buckbeak of a strange illness, Hermione would know exactly where to look.
A group of fairy siblings. They are very mischievous but also very kind - hearted. They can offer their unique fairy magic to assist Jane and the dragon. For example, they can create illusions to deceive their enemies or use their small size to get into places that are otherwise inaccessible.
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 character like a water spirit that has the power to change the tides. This spirit could be both a friend and a mentor to Ariel. It could teach her about the deeper secrets of the ocean and how to use the power of the water to her advantage. Also, a young mermaid princess from a neighboring kingdom who is very competitive with Ariel. They could start off as rivals but then become friends through various adventures. This would add a new dynamic to the story.
Grover Underwood could be included. His knowledge of nature and his ability to sense danger could be very useful. He could provide some comical relief in the midst of the serious prophecy - related events. And his loyalty to Percy would ensure that he is always there to support him, even when dealing with the often - prickly Artemis.
