The Lumpy Space Princess could be a great addition. She could be a sort of mentor to Jake Jr, teaching her about the ways of the different kingdoms in Ooo in her own sassy way.
How about adding a new character, like a young wizard from a far - off land. This wizard could have powers that Jake Jr has never seen before, and they could either become friends or rivals as they interact in the fanfiction. Maybe they team up to fight a common enemy, like an evil sorcerer who is trying to take over Ooo.
The Ice King could also be included. He could start off as an antagonist, trying to capture Jake Jr for some wacky reason, but then as the story progresses, he could end up being an unexpected ally. This would add an interesting dynamic to the story as Jake Jr has to deal with his unpredictable behavior.
Another plot could involve Jake Jr trying to prove herself to Finn and the other heroes. She could take on a difficult quest, like finding a rare ingredient to cure a sickness that has befallen the Candy Kingdom. This would show her determination and growth as a character. It could also involve her making new friends along the way who help her in unexpected ways.
An American wizard detective. He could be investigating strange magical happenings in the wizarding world of America. The Potter character could cross paths with him and end up teaming up to solve a big case.
A young and curious wizard could be added. This wizard could be intrigued by the devil's unbreakable nature and try to study it, leading to some interesting interactions. Another character could be an angel who has lost its way and forms a strange bond with the devil. Or perhaps a talking animal, like a raven, that serves as the devil's confidant and gives it advice from a different perspective.
A mysterious old Pokemon trainer who has a lot of knowledge about ancient Pokemon moves. He could guide Rusty on his journey.
One potential character could be a new time - traveling warrior from a different dimension. This character could bring in unique fighting styles and powers that the Dragon Ball characters have never seen before.
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.
