How to Keep the Same AI Character Across Different Scenes
For a storyboard, comic sequence, or recurring character post, the hardest part is often not the first image.
It is getting later scenes to still look like the same person. One portrait may show the face clearly but hide body proportions, hairstyle details, or clothing from other angles. That is why a reference-based workflow matters. With a model such as Nano Banana, you can work from existing visual references instead of describing the character from memory each time. The process becomes easier when you prepare those references before changing scenes.
Before You Start Prepare a Character Reference Set
Do not begin with the first scene. Begin with the character.
Choose images that clearly show the features you want to preserve. A useful set may include a close portrait, a wider body view, and an alternate angle. If a jacket, hairstyle, glasses, or another accessory defines the character, make sure at least one reference shows it clearly.
Avoid references that disagree with one another. If one image shows short hair and another shows long hair, the model has to decide which version is correct. The same problem appears with different clothing colors, ages, or body proportions.
Your goal is not to collect as many pictures as possible. Your goal is to give the model enough consistent information to answer a simple question: what makes this character recognizably the same person?
Step 1 Choose a Master Identity Image
Pick one image as the main identity reference. This should be the clearest representation of the character’s face and overall look.
A front-facing or three-quarter portrait usually works well because the main facial features and hairstyle are visible. Neutral lighting is useful because heavy shadows can hide details.
Save this master image separately. Before moving on, write a short identity note, such as “same face, shoulder-length dark hair, round glasses, green jacket.” It simply reminds you which visible features matter most during review.
Step 2 Add References That Fill Missing Information
The next references should answer questions the master portrait cannot. This is where multiple images become more useful than several copies of the same angle.
-
Add a Clear Face View
If the master image is wider, add a closer portrait where facial features are easy to inspect. Keep the lighting straightforward and avoid expressions that distort the face too much.
This helps when later scenes use different expressions, angles, or wider framing.
-
Add a Full-Body View
A close portrait says little about height, body proportions, clothing fit, or posture. A full-body reference fills that gap.
Choose a natural pose. If a signature outfit matters, make sure the important parts are visible. This supplies information that a close portrait cannot.
-
Add One Useful Side or Detail View
The last reference should solve a specific problem. It might show the side profile, the back of a hairstyle, a jacket pattern, a distinctive bag, or another feature hidden in the first two images.
Kimg AI currently presents Nano Banana AI as supporting multiple reference images for character consistency, so this kind of complementary reference set fits the workflow naturally. Do not add another image unless it contributes useful information.

Step 3 Write the Prompt Around the New Scene
Once the character is defined visually, stop redescribing every feature in long paragraphs. The prompt should mainly explain what changes.
A simple structure is:
Keep [identity details] consistent with the reference images. Place the character in [new scene], doing [action]. Use [lighting or mood].
For example:
Keep the same face, hairstyle, glasses, green jacket, and body proportions from the references. Place the character in a quiet bookstore, standing beside a shelf and reading a paperback. Use soft afternoon window light.
This makes the scene instruction easy to isolate if the result changes the character too much.
Avoid changing the location, outfit, age, hairstyle, artistic style, and camera treatment in the same step. Build complexity only after the basic identity survives a simple scene change.
Step 4 Generate Only One New Scene First
Do not create ten scenes immediately. Make one second scene and use it as a test.
Choose something simple. If the master image is a standing portrait, place the same character in a café, bookstore, classroom, or street scene with a straightforward pose. The purpose is to test continuity, not drama.
Once the result appears, compare it with the master reference before doing anything else. If the face, hair, body, or signature clothing has drifted, correct that now. Continuing with an unstable second image makes later scenes harder because you may accidentally treat the drifted version as the new character.
If the second scene works, save it as an approved checkpoint before continuing.
Step 5 Compare the Character Side by Side
Never review a character series one image at a time. Put the master reference and new scene beside each other.
Use a short checklist:
-
Face shape and key facial features
-
Hairline, length, and hairstyle
-
Body proportions
-
Signature clothing or accessories
-
Apparent age
-
Skin tone and other stable visual traits
Separate intentional changes from accidental ones. A new expression or planned outfit change is fine; an unrequested change to a defining feature is not.
If you are building several panels, create a simple continuity note. Write down any planned changes such as “removes jacket in scene four” or “hair becomes wet after rain scene.” This prevents intentional story details from being mistaken for model errors.
Step 6 Expand the Series in Small Batches
After two scenes match well, add one or two more. Change the setting or action, but keep most identity instructions stable.
This is the stage where you can introduce more challenging camera angles, stronger expressions, or different environments. Make those changes gradually. If a new angle causes the face to drift, return to the last approved image and your original reference set instead of accepting the change.
For a storyboard, you may also want to keep clothing and props stable across adjacent scenes. For a social character series, background variety may matter more than strict continuity. Decide the rules based on the project rather than applying the same standard to everything.
Small batches make problems easier to trace. You always know which recent change caused the series to move away from the approved character.
Common Mistakes That Break Character Consistency
|
Mistake |
Why It Causes Trouble |
Better Approach |
|
Using conflicting references |
The model receives different identities |
Choose one consistent appearance |
|
Changing many traits at once |
Identity and scene changes compete |
Change scene first |
|
Accepting a weak second image |
Later scenes inherit the drift |
Fix inconsistency early |
|
Reviewing images separately |
Small differences are easy to miss |
Compare side by side |
|
Losing the master reference |
No stable baseline remains |
Keep an untouched source set |
The most important mistake is accepting “close enough” too early. Character drift tends to compound. If scene two is slightly wrong and scene three is based on scene two, the series can move farther away from the original with each step.
Conclusion
Character consistency becomes easier when you stop treating every image as a fresh start. Build a clear reference set, choose one master identity image, add only references that provide missing information, and test the character in one simple new scene before expanding the series. Compare images side by side and fix drift as soon as it appears. You do not need a complicated system to begin. Three useful references, one short preservation instruction, and two test scenes are enough to show whether your setup is stable enough for a longer story.
