Headcanons are a beloved tool in fandoms, letting fans expand upon fictional worlds in personal and creative ways. Not all headcanons are created equal, though — they can be categorized into four main types: Character, Relationship, Scenario, and World headcanons. Each type has its own writing focus and creative potential.

1. Character Headcanons

Definition: Focus on individual characters, exploring traits, quirks, habits, or backstories that aren’t explicitly stated in canon.

Writing Focus:

  • Personality traits: introversion/extroversion, hidden fears, secret hobbies.
  • Habits and routines: how a character spends their day or interacts with minor elements of their world.
  • Development arcs: imagined growth paths or alternative life choices.

Example: Hermione Granger secretly enjoys Muggle board games.

2. Relationship Headcanons

Definition: Explore the dynamics between two or more characters, whether romantic, platonic, or adversarial.

Writing Focus:

  • Interpersonal chemistry: how characters influence each other’s decisions.
  • Emotional depth: hidden feelings, unspoken understanding, or conflicts.
  • Alternative pairings: imagining interactions or relationships not present in canon.

Example: Tony Stark always checks in on Peter Parker after missions, even when not shown in the movies.

3. Scenario Headcanons

Definition: Focus on specific events or situations within the story or imagined “what if” moments.

Writing Focus:

  • Alternate outcomes: imagining a scene unfolding differently.
  • Day-in-the-life moments: ordinary or extraordinary scenarios for characters.
  • Conflict resolution: exploring how characters might react under different circumstances.

Example: What if Katara had joined the Fire Nation’s academy for a day? How would she adapt?

4. World Headcanons

Definition: Centered on the setting, society, or universe of the story rather than individual characters.

Writing Focus:

  • Cultural depth: customs, holidays, or societal norms not detailed in canon.
  • Political or historical context: imagining backstories or events that shaped the world.
  • Environmental details: geography, climate, or hidden places in the universe.

Example: The hidden villages of the Star Wars galaxy have their own local festivals celebrated annually.

Writing Tips Across All Headcanon Types

  • Stay consistent with the tone and logic of the original story.
  • Include small, relatable details that enrich the narrative.
  • Balance creativity with plausibility to make the headcanon believable.
  • Consider your audience: are you sharing with a tight-knit fan group, or publicly for broader discussion?
