Character consistency is the hardest part of AI image generation, which is why this prompt is marked advanced. Three tricks make it work: first, spell out 'same character, consistent facial proportions and colors in every panel' bluntly, even repeating it; second, use a multi-panel character sheet layout so the model references itself within a single image — this holds consistency far better than generating separate images one at a time; third, write the physical traits specifically (color, accessories, body shape) — the more specific, the more stable the result. GPT Image 2's instruction-following and multi-region layout control make it more reliable for sheets than older models, but it's still worth generating a few and picking the most consistent set. Always add 'original design, not resembling any existing cartoon character' to avoid infringement risk — this matters a lot for small businesses that plan to use the result as commercial branding. Skip having the AI render expression labels or speech bubbles, since it's prone to typos there — add that text in post. Once you've picked the best panel, regenerate it enlarged on its own to get a clean final asset.
