Examples

Headcanons for real OCs

Six OCs made in the OC maker, each with the headcanons the generator wrote from one line about them. These are the first few it gave, unedited.

Juniper Wholesome

“an old fairy who runs a tea shop inside a hollow tree and remembers every customer's order”

Juniper hums softly while preparing tea, her melody changing with the seasons.
She has a collection of tiny, hand-painted teacups from around the world, displayed proudly on a shelf.
Juniper always offers a warm, extra biscuit to regular customers without them asking.
She dislikes loud noises and prefers the gentle rustling of leaves outside her shop.

Dex Funny

“a delivery robot who is always late because he stops to help everyone on the way”

Dex has a habit of spinning in circles whenever he's confused, which is often.
He loves collecting random shiny objects from people's porches but has no clue why.
Despite being a delivery robot, Dex can't resist stopping for an impromptu dance party with strangers.
He hates loud noises and will dramatically cover his speakers when a car backfires.

Sable Angsty

“a former royal knight who left her order after a betrayal and now works as a bodyguard for hire”

Sable always checks the locks twice before settling in anywhere, haunted by a past betrayal that nearly cost her life.
She finds comfort in old, worn-out battle gear, believing it carries the echoes of her honor and past victories.
Despite her tough exterior, she quietly protects stray animals she finds during her travels, recognizing a kindred loneliness.
Sable keeps a faded pendant from her royal days hidden beneath her armor, a reminder of who she once was.

Pico Wholesome

“a shy red panda who is an apprentice mail carrier and is scared of thunder”

Pico always carries a tiny notebook to doodle little red pandas during slow moments at work.
They love the smell of fresh rain but get nervous when it turns into a thunderstorm.
Pico has a habit of quietly humming cheerful tunes while sorting mail to calm their nerves.
With close friends, Pico becomes surprisingly playful and enjoys gentle teasing games.

Riven Funny

“a demon who quit the underworld to open a tiny ramen stall and takes bad reviews very personally”

Riven insists on wearing a chef's hat almost twice their size, but it always slips over their eyes mid-shift.
Despite being a demon, Riven is terrible at scaring people and instead just accidentally makes everyone laugh.
They refuse to serve anyone who doesn't appreciate extra garlic, calling them 'soul-starved'.
Riven practices ramen slurping techniques in front of the mirror like it's a sacred ritual.

Mira Mixed

“a mermaid lifeguard who has never actually been on land but gives everyone advice about it”

Mira always twirls a small shell necklace when she's thinking, a gift from her first rescue.
She dislikes loud noises on the beach because they remind her of storms underwater.
She's fascinated by human shoes, even though she can't wear them, and has a secret collection of them in a hidden underwater cave.
With friends, she’s protective but also enjoys playful teasing to lighten tense moments.

How to get good ones

Write who they are, not what they look like: "a grumpy ghost who keeps lighting lanterns for lost travelers" works better than "grey hair, green cloak". Pick a mood if you want the list funny or a bit sad.

Take what fits

They're ideas, not facts. Throw out the ones that don't feel like your character, and run it again for a new batch.
