One of the hardest things in AI image-making is getting the same character to appear across several pictures. By default every generation is a fresh roll of the dice. With a few habits you can keep a character recognisable enough to tell a story, make a series, or build a brand mascot.
Consistency starts with a fixed block of words you reuse every time. Pin down the details that define the character: "a young woman with short copper hair, green eyes, freckles, round glasses, mustard-yellow jacket". Keep this exact phrasing and paste it into every prompt. The more specific and unusual the details, the more reliably they come back.
Changing the art style breaks consistency as badly as changing the features. Decide on one style — "3D render", "flat illustration", "anime" — and lock it alongside the description. A character drawn as a 3D render in one image and a watercolour in the next will never feel like the same person.
Many image tools let you set a seed — the number that controls the random starting point. Reusing the same seed with the same prompt keeps results close together, so changing only a small part of the prompt (the pose, the background) while holding the seed steady is a good way to get variations of the same character rather than a new one each time.
The most reliable trick is to stop regenerating from scratch. Once you have a character image you like, take that image into the image editor and change one thing at a time — "now put her in a forest", "now have her wave". Because you are editing the existing picture, the face and outfit carry over far better than a brand-new generation would.
This "sheet" becomes your reference, just like an animation studio would use.
Free tools will not give you flawless, frame-perfect consistency — that is still hard even for paid systems. Aim for "clearly the same character" rather than "identical to the pixel". For a short comic, a set of mascot poses or a storybook, that is more than enough. And once you have a consistent character image, you can even bring it to life as a short clip.
