Animating FusionFall: Building a Workflow for Consistent Fan Media
FusionFall has a very specific and recognizable visual style. Its characters use an inverse hull toon shader, giving them a distinctive silhouette defined by bold toon outlines. Preserving this look is essential when creating AI-generated videos or reinterpretations based on FusionFall assets.
This page documents the process I’ve been developing to generate consistent animation and fan media from in-game screenshots, without drifting away from the original art direction.
For a recent project, I created animations of Lance and Ilana from Sym-Bionic Titan. Below, I’ll walk through the steps we used, the tools involved, and how we adapted prompts to better match our visual goals.
Our team currently uses Runway ML’s Unlimited Plan, but for smaller or amateur productions, Leonardo AI offers a cheaper and often more effective solution.
I first asked ChatGPT:
“Describe how you would animate Lance from Sym-Bionic Titan and then write a prompt for that.”
Here’s what it generated:
Prompt: Animate a character inspired by Lance from Sym-Bionic Titan in the visual style of Genndy Tartakovsky. Use sharp, clean linework with flat cel shading and bold silhouettes. The character should appear stoic and disciplined, with reserved facial expressions, mostly neutral or slightly stern. Animate subtle motions: slight brow movement, tight mouth, controlled posture. When in action, depict powerful, efficient body language with punchy, angular movement arcs. Emphasize hold frames on key impacts and avoid excessive smear frames. Background should be minimal or abstract, focusing attention on the figure’s silhouette and precise animation timing.
This prompt produced solid stylistic results, but the animation had too much movement for a character like Ilana, who needed more subtlety. So we changed our approach.
I started with a similar prompt for Ilana:
“How would you do Ilana? Give me a prompt for her.”
But again, it added too much motion. So I refined the request:
“Just make her talk. Maybe the camera zooms in.”
And this was the improved result:
Prompt: Animate a close-up talking scene of a stylized princess character inspired by Ilana from Sym-Bionic Titan, using Genndy Tartakovsky’s visual style. Begin with a medium shot and slowly zoom in toward her face as she speaks. She has an elegant, poised demeanor with soft, expressive facial acting: subtle brow movement, gentle blinking, and clearly articulated lip sync. Her eyes occasionally glance to the side or shift slightly as she thinks. Her posture is upright and noble. Her gestures are delicate, such as one hand near her chest as she emphasizes a point. Use clean linework, flat cel shading, and a minimal background to keep focus on her graceful expression and composed delivery.
Below are the resulting animations created using the Lance prompt above:

Before starting animation, I accidentally ran the Lance video prompt through Leonardo using the Flux model by Kontext. Instead of creating a video, it generated a single still image. The result was unexpected but surprisingly effective. It reimagined Lance with a completely different visual tone that still felt adjacent to FusionFall. We might use this approach more going forward as a stylized reinterpretation technique.
