One interesting story could be about a fairy leviathan that forms an unlikely friendship with a young mermaid. They go on adventures together, exploring the deep sea and encountering other magical creatures. The fairy leviathan uses its magical powers to protect the mermaid from various dangers.
First, think about the characteristics of the fairy leviathan. Is it more fairy - like or more leviathan - like? Decide on its appearance, powers, and personality. For example, if it has a very gentle nature but powerful magic, that can shape the story. Then, come up with a basic plot, like a quest it has to go on or a problem it needs to solve.
There could be a fanfiction where the fairy leviathan and zero are from different worlds but are brought together by fate. Their relationship starts off rocky as they don't understand each other's ways. But as time passes, they learn to appreciate and rely on one another, and they end up saving both of their worlds from a great evil.
Begin by outlining the story. Decide on the main events that will happen. Consider how the fairy leviathan's magic and zero's abilities will interact. You could have them combine their powers to defeat a common enemy. In the story, include details about their emotions and thoughts. For instance, if they face a difficult decision, show how each character feels about it. Also, use descriptive language to bring the world you create to life. Describe the scenery, the sounds, and the smells. This will make your fanfiction more immersive for the readers.
