One Line Drawing, Many Poses — AI Pose Transformation and Coloring at Once
When drawing a webtoon, there are many moments when you need the same character in a variety of poses. You've finished the base line art — but drawing that character in an attack scene, a defense scene, and a running scene requires hours of additional work.
With XBRUSH's Pose Change feature, you can generate multiple action poses from a single piece of line art. What made it especially interesting was that pose transformation and coloring happen simultaneously.
XBRUSH's Pose Change feature generates action poses and full coloring from a single webtoon line drawing in one step — cutting hours of manual pose variation and coloring work down to a single prompt.
The Line Art Characters We Used
Ten fantasy hero characters drawn in webtoon style — Hunter, Holy Knight, Barbarian, Mage, Ghost Blade, and more. We selected three of them to test the Pose Change feature.
1. Hunter — Attacking Alongside a Wolf
The Hunter character's original concept sheet, including a full-body pose and three facial expressions — the character design is fully established at the line art stage.
The original line art of the Hunter standing with her wolf companion. We fed this into XBRUSH's Edit > Pose Change (nanobanana) and entered the prompt: "Attacking together with the wolf, and add coloring."
The results: a pose running alongside the wolf with a spear in hand, another aiming a gun with the wolf charging beside her — multiple action scenes generated in full color. The original costume and character style carried through into every variation, with pose and coloring transformed simultaneously.
2. Holy Knight — Jumping Attack with Shield and Hammer
The Holy Knight's original line art, holding a shield and hammer in a straightforward standing pose. Prompt: "Blocking with a shield while raising a hammer overhead in a jump attack, add coloring."
3. Barbarian — Swinging an Axe to Attack
The Barbarian's original line art, facing forward with dual axes in a threatening stance. Prompt: "Swinging a weapon in an attack, add coloring."
The results for both characters. The Holy Knight appeared in silver armor with a blue cape, hammer raised high. The Barbarian was rendered with a muscular build in heavy armor, swinging an axe in a dynamic downward strike. The flat line art gained color and dimensionality that wasn't present in the original sketches.
Pose and Coloring in One Step
Two things stood out as practically useful about this workflow:
- Pose and coloring happen together. No separate coloring step needed — the action pose and color palette are both generated at once.
- Character identity is preserved. Costume, weapons, body type — the core design elements from the original line art carry into each new pose variation.
The full workflow from line art to colored action pose follows these steps:
- Prepare the line art — Use a clean, well-defined line drawing with clear character silhouette and distinct costume details.
- Open XBRUSH Edit > Pose Change — Upload the line art to the Pose Change tool (nanobanana model).
- Write the action prompt — Describe the target pose and specify "add coloring" to trigger simultaneous color generation (e.g., "Attacking together with the wolf, and add coloring").
- Review the generated variations — Multiple results are produced in one run. Select the pose that best fits your scene.
- Use as a reference or foundation — Apply the output as a draft for manual illustration refinement or as a scene composition guide.
This works best as a way to generate references or rough drafts rather than finished art. The use case is quickly visualizing how a scene might look, and using that output as a foundation for the actual illustration work.

Frequently Asked Questions
Q: Does Pose Change work on any line art style, or does it need webtoon-style drawings?
It works best with clean, well-defined line art. Webtoon-style drawings with clear outlines and distinct character silhouettes give the most consistent results. Looser or more painterly sketches may produce less predictable pose transformations.
Q: Can I control which color palette the character gets when coloring is applied?
You can guide the coloring through the prompt — for example, specifying armor color, skin tone, or costume details. However, the AI makes final decisions on the palette, so results may vary. Running multiple generations gives you options to choose from.
Q: Is Pose Change suitable for creating final production art, or just reference images?
It works best as a rapid reference and ideation tool. The output gives you a colored pose variation you can use as a foundation for manual illustration work — checking proportions, scene composition, and mood — rather than as print-ready finished art.
