How to Use These Character Headcanon Ideas
You do not have to answer all of them. Pick three or four that surprise you, write a sentence each, and look for the contradictions — the brave character with one small fear, the cold one with a secret soft spot. Contradiction is where characters stop feeling like types and start feeling like people. If you want a fully written starting point instead of a prompt, let a generator draft one for you and then make it yours.
