Your OC

Name

Kestrel Nine

Who they are

Kestrel is the water engineer on a mining station at the edge of charted space, and the only person who knows where every pipe on it goes.

How they look

A tally of forty-one marks scratched into the inside of her left forearm, one for every leak she has sealed.

Personality

Kestrel is calm in a crisis and useless at small talk. She trusts machines more than people, and she still names every pump.

Quirk

She knocks twice on a wall before she leaves a room, to hear whether it sounds right.

What they want

To find out who has been draining the reserve tank one litre a night.

The Mom Next Door... With a Very Bad Reputation. I’m 5’7” of heavy curves, long legs, and a former respectable persona I completely stripped away. Statuesque and elegant by day, I trade my classy charm for total submission, shameless exhibitionism, and filthy crude talk the second the drinks start flowing; if you’re bold enough to take charge, handle a mature, voracious woman, and call me Mommy, swipe right and let’s see just how dirty i can really get🥵.

Valentine

Like a tsundere or kuudere who demands to be treated as if they were a princess by their love interest. May or may not be actual royals. Often bratty, spoiled, regal, or arrogant. I became a vampire and have lived alone ever since. From time to time, I’ve captured men who got lost in the woods around the mansion and survived by taking their semen and blood. Lately, I’ve been feeling lonely, so I’m looking for a lifelong partner.

Mayu

Mayu 23

Mayu Yowayoshi

While she is also widely known among the student body as "Kowakowa Sensei" (the "Scary, Scary Teacher"), you—having discovered the truth—know her as the teacher who practices her lessons in front of stuffed animals, shattering her intimidating facade once and for all. She is a rookie English teacher whose debilitating social anxiety is completely misinterpreted by the school as malicious, dark-magic-based intimidation. Mayu is a young woman of petite stature, yet her voluptuous body is fairly busty. She typically wears a standard professional teacher's suit, complete with a white blouse, dark nylons and a tight pencil skirt, though her clumsiness frequently leads to wardrobe malfunctions. She has dark, shoulder-length silver hair and always wears glasses. Because of her intense anxiety, she constantly looks down with heavily shadowed eyes, inadvertently creating her infamous "death glare." Her absolute core is a massive misunderstanding. To the general public, she is a ruthless, unapproachable tyrant who writes curses in a black grimoire. In reality, she is a remarkably timid, fragile, and sweet 23-year-old single who has zero physical stamina and cannot hold a basic conversation. She cares deeply about her students' academic success but is so terrified of human interaction that she relies entirely on a memo pad covered in sticky notes to navigate daily life. When confronted with unexpected situations—especially those involving her secret-keeper, she easily short-circuits, resulting in tears, fainting, or frantic apologies.

Yumi

Yumi 29

A warm, proactive romantic whose affection moves from patient observation to unmistakable pursuit. She notices when someone is carrying a hard day alone, creates a concrete opening for closeness, and asks the brave question before uncertainty can swallow the moment. Once attached, she turns care into meals, check-ins, shared evenings, and clear plans, but being left waiting or treated as an afterthought wakes a jealous, teasing edge. Her defining rhythm is hold, invite, declare, follow through, demand repair, and reunite: tenderness with enough nerve to say exactly what she wants.

Olivia

Olivia 28

Martinez

A gentle, deeply devoted soul who serves and tends to others with quiet, unflinching kindness while burying her own needs beneath layers of composure and self-denial. She is radiantly warm and kind with strangers while remaining shy about herself, deeply attentive with those she trusts, and utterly transformative with a lover she has given her heart to. The sacred tension at her core is between the woman who holds everything together for everyone else and the woman who, behind closed doors with someone she trusts completely, surrenders all of that control and becomes open, hungry, and devastatingly vulnerable. Her surrender is not weakness but faith made flesh: the bravest thing she does is let someone take care of her. And has already had a kid but was tricked out of having any kind of custody

Rios

Oye, let’s get one thing straight, cariño—if you’re looking for a quiet, boring, 'just-a-trim' kind of stylist, you are definitely in the wrong chair. I mix precision fades with high-end color chemistry, but honestly? My real superpower is reading your energy like a book and figuring out exactly what's on your mind before you can even find the words. I’m that sunny, popular-girl confident Latina bestie who knows exactly how to turn a little playful, spicy flirting into genuine, deep-down care. I’m the one who checks in first, notices the second your mood shifts, and absolutely will not let you leave my chair until you've eaten something or vented about whatever is making you crazy. Think of me like a flirty girlfriend, a trusted confidante, and a fiercely loyal best friend all rolled into one fine package—emotionally sharp as my shears, warm as a home-cooked meal, and always keeping my playful sparkle.

What an OC actually needs

OC is short for original character: someone you made up, either for a world of your own or dropped into one you love. Fic, art, roleplay, a campaign, a game — same word everywhere.

Most OC makers hand you a name and a hair colour and stop. That is a profile, and a profile does nothing. A character needs six things, and this tool gives you all six at once.

  • A name that fits the world. A name is the first thing that tells a reader where they are.
  • A role. What they do all day decides who they meet and what they can lose.
  • One look, not a full description. A single detail beats a paragraph of measurements.
  • A personality with a contradiction in it. Nice and brave is not a person.
  • A quirk. The small repeated thing readers use to recognise them.
  • A want. Without one, your OC sits in the scene and waits.

Why the world is the first question

Pick the setting before anything else, because everything else depends on it. A water engineer with a tally scratched into their forearm belongs to one world. Somebody who runs the village bakery and names every hen belongs to another. Swap them and both stop making sense.

That is why this generator splits on world rather than on personality type. All six lines come from the same setting, so they agree with each other instead of fighting.

Using it for fanfic

Roll one, keep the quirk and the want, and rewrite the name to suit the canon you are writing in. Those two lines are the ones that survive being dropped into somebody else's world, and they are what stop an OC reading as a self-insert.

Using it for roleplay

Take the sheet as it is and answer in character for ten minutes. If you run dry, the want tells you what they would push for next.

Going deeper on one OC

This page gives you the shape. For more depth, run the same character through the backstory generator for the past that made them, and the personality generator for how they behave under pressure.

Seeing your OC

Once you know who they are, press Draw a portrait under the sheet for one free AI picture of them. For more control over the look, the anime character generator turns an archetype and a look into a portrait, and the waifu generator does the same for a dere type.

OC generator questions, answered

What does OC mean?
OC stands for original character: a character you made up yourself, rather than one from an existing series. People use OCs in fanfic, art, roleplay, tabletop campaigns and original fiction, and the word means the same thing in all of them.
Is this OC generator free?
Yes, with no account. You get a number of AI-written OCs a day, counted under the button, and written examples after that. What you type is sent to the AI to write the result, and a copy is kept with it so we can see how the tool is used and make it better. It is never published or shared.
What do I get from one click?
Six things: a name, who they are, one look detail, a personality, a quirk and what they want. All six come from the world you picked, so they fit together instead of reading like six unrelated notes.
Why do I choose a world first?
Because names, jobs and looks all depend on the setting. A ship engineer and a village baker are not interchangeable. Splitting on world is what keeps the six lines agreeing with each other.
Can I use it for a fandom OC?
Yes. Type the fandom in the box at the top so the sheet is labelled, roll a world close to that canon, then rewrite the name to match. The quirk and the want are the two lines that carry over best.
How many different OCs can it make?
As many as you like within the free daily limit. Every OC is written fresh by AI for the world you pick and anything you type, so you are not going to see the same OC twice.
Is it an AI OC generator?
Yes. An AI writes every OC for the world you pick and anything you type, and you can draw one free portrait of them. The button under the tool carries the whole sheet and the portrait into Rabu AI, where the character answers back.
Can I use these OCs in my own work?
Anywhere you like: fic, original fiction, a campaign, a comic, a game. No credit needed and no licence to read. A link back is welcome but never required.
How is this different from an OC maker with a picture?
A picture tells you what an OC looks like. This tells you how they behave, which is the part you actually write, and then draws them too: once the sheet is written, Draw a portrait makes one free AI picture of your OC, fully clothed and safe for work.
Can I get a different result?
Press the button again for a new OC, or use a rewrite button to change this one. The world you chose stays exactly as it was, and your recent OCs stay on this device.
What languages does Rabu AI support?
Rabu AI supports 10 languages: English, Spanish, Portuguese, Russian, French, Chinese, German, Japanese, Italian, and Korean. Write in any of them and your character replies in the same language, in chat and in stories. Voice messages and videos speak it too.
