Character Design Prompt Generator

Choose how many prompts you want, from 1 to 10, and press Generate Prompt. Each result is a one-sentence brief in the form "Design a cunning character who is a mage in a steampunk setting, located in a castle, who is part animal." The list holds 500 of these, and every one fixes the same five things: personality, role, genre, location and a twist. What the character looks like is left entirely to you, which is the point of a design prompt rather than a description.

It's built for illustrators doing daily sketch practice, character-design students who need constraints, and writers or game masters who want an NPC with a hook. If you use AI image tools, the sentence also works as a starting prompt, though you'll want to add style and framing words yourself.

The five slots, and what's in each

Every prompt draws one option from each of five sets of eight:

• Personality: brave, comic, cunning, eccentric, heroic, mysterious, villainous, wise.
• Role: assassin, detective, explorer, inventor, mage, pirate, scientist, warrior.
• Setting (genre): ancient, cyberpunk, fantasy, futuristic, medieval, modern, post-apocalyptic, steampunk.
• Location: castle, city, desert, forest, mountains, space station, underwater, village.
• Twist: on a quest for a lost treasure, has a secret identity, has a twin, is a time traveler, is part animal, with a magical artifact, with a robotic companion, with a unique ability.

Eight options in five slots makes 32,768 possible sentences; the list contains 500 of them, with no duplicates. The interesting prompts are the ones where slots collide: a pirate on a space station, a mage in a cyberpunk city, a medieval assassin with a robotic companion. Those contradictions are where a design starts to get specific.

Turning a prompt into a design

A brief like "a wise detective in a modern setting, located in the mountains, who has a secret identity" gives you decisions to make, not answers. Work through them in order. Personality sets posture and expression: wise reads as stillness and a level gaze; eccentric reads as asymmetry. Role sets the silhouette and the props: a detective carries evidence, a scientist carries instruments. Setting decides materials and technology, so the same detective in a cyberpunk city gets neural implants where the modern one gets a phone. Location adds weather and wear: mountain characters are layered and wind-burned, underwater ones need a way to breathe. The twist is the storytelling detail that goes in last, often as one small object, scar or companion that hints at more.

For the parts this generator leaves blank, the site has dedicated pickers: the Random Eye Color Generator, Random Hair Color Generator and Random Height Generator settle the physical build, and the Likes and Dislikes Generator adds a few traits that show up in how the character dresses and what they carry. The whole set is under all people & character generators.

Practice ideas

• Thirty-minute sketch. One prompt, one timer, no reference. The constraint is the exercise.
• Silhouette first. Generate three prompts and draw only a black shape for each. If a viewer can't guess the role from the shape, redesign.
• Same character, five settings. Keep the personality and role from one prompt and redraw them in each of the eight genres. Good for portfolio pages that show range.
• NPC table. Game masters can generate ten prompts and keep them as a list of ready characters for when players wander somewhere unplanned. Add a job with the Random Job Generator if the role slot is too heroic for a shopkeeper.
