What is a headcanon?

A “headcanon” is a detail about a character or setting that isn’t official in the source material — a fan’s personal interpretation, treated as canon inside their own head. The generator gives you a starter set of traits you can mix into an existing character, an original cast, or a tabletop RPG NPC.

How to use the output

Regenerate until something sparks. Keep the parts you like and swap the rest. The most useful traits tend to be the contradictions — a character whose vibe and motivation pull against each other usually has more story in them than one who’s internally consistent.
