A fanfic
Fanfic is when someone writes a story about characters they like from a book, show, or game. They usually don’t care if the original author would throw a fit.
I read a fanfic where Dobby and Harry Potter got married. It was weird but also sweet.
My brother wrote a fanfic where Goku and Vegeta had a kid who could fight like both of them. It was epic.
My friend wrote a fanfic where SpongeBob and Patrick went to a party. It had a lot of dancing and a lot of pizza.
