A wise old owl could be a new character. This owl could be the one who actually has knowledge about the real threats (or lack thereof) in their world. Maybe he tries to guide Chicken Little and the other animals. Another potential character could be a mischievous squirrel. The squirrel could be constantly causing small troubles that make Chicken Little think the sky is falling all over again. For example, it could knock down acorns that make loud noises.
A wise old sea turtle could be a new character. He could be the one who gives the mermaid advice about the human world and warns her of the potential dangers.
A merman from a far - off part of the ocean. He could have unique powers, like the ability to control the tides. He might befriend Ariel and join her on her adventures, or he could be a rival for her affections.
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 friend for the little sister from outside the Lab Rats' world. This character could introduce her to normal teenage life things like school dances and homework, which would be a contrast to her life as part of the Lab Rats' family. It could also create some internal conflict as she tries to balance both aspects of her life.
Well, of course, there's the little vampire himself. He could have a best friend who is a human, a brave kid who is not afraid of the vampire's nature. There might also be an old vampire mentor who teaches the little one about vampire traditions and how to control his thirst.
The main characters are Abby and Chicken Little. In fanfiction, Abby could be a curious and adventurous character. She might be the one to initiate most of the adventures or challenges that they face. Chicken Little, with his famous 'the sky is falling' catchphrase, brings his own set of comical and sometimes over - worried characteristics to the stories. Their relationship, whether it's a friendship or a partnership in facing difficulties, is what makes them the main characters in these fanfictions.
A young, adventurous boy from a neighboring town. He could be quite different from the characters Little Miss Marker is used to. He's full of energy and new ideas, and together they could get into all sorts of escapades, like exploring an old, abandoned castle.
Obviously, the bumblebee itself is a main character. There could also be other insects like butterflies, ladybugs, and ants. Maybe a wise old spider who lives in a corner of the garden and gives advice to the bumblebee.
In a Nuclear Throne Chicken fanfiction, the other powerful characters in the game who have different goals than the chicken could be antagonists. For instance, if the chicken is on a mission to restore a certain part of the world, those who want to keep the chaos and destruction might oppose it. There could also be a mad scientist - type character who wants to experiment on the chicken to steal its powers, making them a significant antagonist.
If it's a more complex 'little chicken story', there could be a wise old owl that gives advice to the little chicken. There might be some mean foxes or weasels that are the antagonists, always trying to catch the little chicken. And of course, there would be other chicks that are the little chicken's siblings or friends. They could play together, search for food together, and face difficulties together.
