To write 'Prince Zuko and OC fanfiction', start with creating a unique OC. Consider their appearance, values, and goals. Let's say your OC is an artist. How would that affect their relationship with Zuko? Maybe they use their art to communicate with him. When it comes to the story, create a conflict. It could be internal, like Zuko's struggle with his identity, or external, like fighting a new threat. You can also include other characters from the Avatar world to make the story more interesting. Write in a way that shows the growth of both your OC and Zuko throughout the story. And don't forget to proofread your work to make sure it flows well.
