A headcanon is a fan's personal interpretation or belief about a fictional character, relationship, or universe that isn't officially established in the source material (canon). Headcanons can include anything from a character's favorite food, secret hobbies, childhood memories, to relationship dynamics between characters. They're a creative way for fans to expand on their favorite stories.

What is the difference between headcanon and canon?

Canon refers to officially established facts within a fictional universe created by the original authors or creators. Headcanon is a fan-created interpretation that fills gaps in the official story.

Headcanons aren't official but are widely accepted in fan communities.
