What is a Headcanon?
A headcanon is a fan's personal belief or interpretation about a fictional character or story that isn't confirmed in the original source. Fans use headcanons to imagine character backstories, relationships, personality traits, or unseen moments—then share them through fanfiction, art, or roleplay.
The term combines "head" (your personal thoughts) + "canon" (official story material). Unlike fanon (widely accepted fan theories), headcanons are individual—they exist in your head only, unless you choose to share them.
Common Headcanon Types
- • Character backstories not shown in canon
- • Hidden relationships or shipping dynamics
- • Personality quirks and habits
- • "What if" scenarios and AUs
How Fans Use Headcanons
- • Writing fanfiction and fanart
- • Roleplay character development
- • Social media discussions (Tumblr, Reddit)
- • Creating shareable content cards
