Nano Banana Character Sheet Prompt (Consistent Character)
Character consistency is the hardest problem in AI art — and the one Nano Banana is famous for solving. This prompt turns one reference image into a 3-panel character sheet (full body, face close-up, action pose) with the same face, outfit, and style locked across all three, giving you a reusable character for comics, story posts, games, and brand mascots.
Keep the same character across every image: the Nano Banana character sheet prompt creators use for comics, stories, and brand mascots.
Use the uploaded image as the character reference. Maintain the exact same character in all panels: identical face, hairstyle, hair color, body proportions, and outfit design. Generate a 3-panel character sheet on a clean light background: Panel 1: Full body, standing in a neutral pose, front view, wearing the reference outfit. Panel 2: Close-up of the face, laughing, three-quarter view. Panel 3: Action pose, jumping, dynamic low-angle view. Flat 2D animation cel-shaded style, consistent line weight and color palette across all three panels, character-design reference sheet layout. No text, no labels, no watermark.
See what this prompt creates
Every AI artist hits the same wall: you generate a character you love, and no prompt on earth will give you that exact person again. Gemini's Nano Banana broke the wall — its large context window lets it hold a reference face and outfit across new scenes, which is why "consistent character" became its killer use case. The character sheet is step one of that workflow: one reference image in, a proper design sheet out.
How to use it
- Start with your best single image of the character — AI-generated or a photo. Front-facing, clearly lit, outfit fully visible.
- Upload it to Gemini, paste the prompt, generate the sheet.
- Save the sheet itself: it's now your master reference. Upload the sheet (not the original) when generating new scenes — three views anchor identity better than one.
Why this prompt works
Consistency fails when each generation reinterprets the character from words alone. This prompt attacks that in three ways. It declares the reference image the authority ("maintain the exact same character") and enumerates what must not change — face, hair, proportions, outfit — because unnamed attributes drift first. It asks for the three views in one generation, so the model designs one character and poses it three ways, instead of inventing three cousins across separate calls. And it pins a single rendering style ("flat 2D cel shading, consistent line weight and palette") across the whole sheet — style drift is identity drift in disguise. The clean background isn't decoration either: it makes the sheet easy to reuse as a reference and to cut out for comics or video work.
After the sheet: putting your character to work
- New scenes: upload the sheet and prompt "the character from the reference sheet, [new scene and pose], same art style" — coffee shops, battles, album covers.
- Expressions pack: one more sheet with the same structure: replace the three poses with six facial expressions for reaction images and stickers.
- Outfit variants: keep the face panels identical and change only the outfit line — a wardrobe sheet for a character you'll dress by season or story arc.
- Photoreal characters: swap the style line for "photorealistic, shot on 85mm" — Nano Banana holds real faces the same way, which is how creators keep a consistent 'actor'.
Creators pair this with our character interview prompt — sheet for the look, interview for the personality — and storytellers file it next to the writing prompts. More Gemini-native techniques are in the Gemini AI Photo Prompts collection.

Frequently asked questions
Can I use a real photo of a person as the reference?
Yes — Nano Banana holds photographic faces too. Use your own photo or one you have rights to; turning a real person into a recurring 'character' without their consent is where this stops being a fun tool.
Why did the outfit change between panels?
Outfit drift usually means the reference outfit was partly out of frame. Re-upload a reference where the full outfit is visible, and describe one signature outfit element in words ('red scarf', 'denim jacket') inside the prompt as a second anchor.
How many panels can I ask for?
Three to four panels stay sharp. Beyond that the sheet gets crowded and individual panels lose detail — generate a second sheet for expressions or outfits instead.
Does this work for product mascots and logos?
Yes — brand mascots are one of the most common uses. Generate the mascot once, build its sheet, and every future ad or post starts from the sheet as reference. Keep text and logos out of the sheet; add them in your design tool afterward.
