Can I use TV characters in a fantasy book as scary characters? Is it violating copyright laws?
What circumstances would those be?
One possibility is if your use of the characters falls under the legal principle of "fair use." This principle allows for some uses of copyrighted material without permission, such as for purposes like criticism, commentary, news reporting, teaching, scholarship, or research. However, the specific facts and circumstances of your use will determine whether it falls under fair use or not, so it's important to think carefully about how you plan to use the characters and consult a legal expert if you're unsure.
