Heroes, villains, creatures and mascots
Describe any character, from a starship engineer to a swamp witch or a bakery mascot, and get finished character art in the style you name. Upload a sketch to steer the design.
An AI character generator turns a written description into character art. On OC Generator you describe a character's role, look and style, or upload up to 3 reference images, and Seedream 4.5 draws them in 2K or 4K for 10 credits an image; Nano Banana 2 keeps an existing character consistent for 20 credits. Signing up is free; images use purchased credits.
Fantasy, science fiction, cozy slice of life, steampunk, gothic or superhero: name the setting and the outfit and props follow it.
Generate humans, elves and orcs, talking animals, robots, monsters and brand mascots, each with a clear silhouette.
Anime, comic ink, watercolor, painterly concept art, pixel art, 3D render or flat vector; one style word changes the whole look.
Upload up to 3 images, such as a rough sketch or a costume reference, and the model follows their shapes and colors.
Keep a character recognizable across scenes with Nano Banana 2 and an uploaded picture, so the same cast can appear throughout a comic or a game.
Role, look, outfit, props and art style in one or two sentences.
3:4 or 9:16 for full-body art, 1:1 for avatars, 16:9 for scenes; 2K or 4K with Seedream 4.5.
Make up to 4 versions per run, keep the best and refine one detail at a time.
An AI character generator draws a character from a description. Instead of picking from preset parts, you write what the character is like, and an image model turns the words into a picture: face, outfit, pose, light and background.
It is a quick way to explore a design before you draw it yourself or commission an artist, to give a story or tabletop game a visual cast, or to make a mascot for a stream or a small brand.
A character creator usually means a builder where you adjust sliders and pick parts, as in many games. A character generator invents the image for you from a prompt. OC Generator is a generator: you describe, it draws, and you refine with words or reference images.
It makes images only. Names, backstories and game statistics are yours to write; put the visible parts of them, such as a scar, a uniform or a lucky charm, into the prompt.
Character designers come back to the same few rules:
Writers use generated art to keep a cast in mind while drafting, game masters hand portraits to players, and indie developers rough out party members and enemies before the final art. For a recurring character, save the best image and upload it whenever you need them again.
Both models draw characters from text and accept reference images. Pick by the job.

Start with Seedream 4.5 at 10 credits: it draws detailed new designs and outputs 2K or 4K. Use Nano Banana 2 at 20 credits once you have an image you like and want that same character in new poses or scenes.
Creating an account is free, but generating images is not: each image uses purchased credits, 10 with Seedream 4.5 and 20 with Nano Banana 2. There are no free trial credits.
Yes, from drawings. Upload up to 3 images, such as a sketch, a costume reference or an earlier character image, and describe what to make. Turning photos of real people into characters is not allowed.
No. OC Generator makes images only. Write your character's name and backstory yourself, then put the key visual details from it into the prompt.
