Learn how to create consistent AI characters for fantasy art using prompts, reference images, seeds, and custom model training. Step-by-step guide for writers and worldbuilders.
Creating a single compelling AI fantasy character is easy. Keeping that same character consistent across multiple scenes, poses, and environments is where most creators struggle.
If you’ve ever generated a perfect hero—only to watch their face, proportions, or style change in the next image—you’re not alone. This challenge is common across all AI character creation, but it’s especially noticeable in fantasy art where visual identity matters most.
This guide walks through a practical, step-by-step process for creating consistent AI fantasy characters. From early character planning to prompt design, reference images, and custom model training, you’ll learn how to maintain visual continuity across an entire project. Whether you’re a writer visualizing a novel’s cast, a game designer building a world, or a digital artist refining characters, these techniques will help you keep characters recognizable and reliable.
AI image generators don’t remember characters between generations. Most models begin from random noise and refine the image based on your prompt. Without strong constraints, the AI has wide creative freedom—leading to different interpretations of the same character.
Even small changes in wording, lighting, or composition can cause noticeable shifts in facial features, body shape, or style. The key to consistency is reducing randomness and giving the model clear, repeatable guidance.
Before writing a single prompt, define your character in detail. Think of this as a digital character sheet that you’ll reference throughout the project.
Include:
Example character blueprint:
Lyra Meadowlight — a halfling druid with honey-blonde curly hair tied with a leather cord, bright green eyes, light freckles, a linen tunic, barefoot, carrying an oak staff with a softly glowing crystal.
This description becomes your consistency anchor.
Your goal here is to create one strong base image that clearly represents your character.
A reliable base prompt usually includes:
Example base prompt:
Portrait of Lyra Meadowlight, a halfling druid with curly honey-blonde hair, bright green eyes, and freckles. Wearing a simple earth-toned linen tunic. Soft cinematic lighting, plain grey background, detailed fantasy illustration.
Generate variations until one image matches your vision closely. Save this image—it will serve as your primary reference.

Seed values control the starting noise pattern for generation. Reusing the same seed while making small prompt changes often produces similar results.
Locking seeds is useful for:
On Fiddl.art, you can lock the seed in the Create interface and tweak your prompt for variations.
Uploading your base image as a reference helps preserve facial structure and style. You can then prompt variations like:
Lyra Meadowlight in a quiet forest clearing at dawn, light mist between tall trees, detailed fantasy illustration.
This approach dramatically improves consistency compared to text-only prompts.
For long-term projects, custom model training is the most reliable solution.
If you’re working on:
Training a character model can save significant time.
Instead of reinterpreting a description each time, the model learns your character as a concept. This dramatically improves consistency across poses, scenes, and styles.
A typical workflow:
Tools like Forge on Fiddl.art are designed for this kind of character-focused training and are especially useful for writers and developers who need dependable results across many images.

These consistency principles apply well beyond fantasy. They work for:
The genre changes, but the process remains the same: define clearly, establish a base, and reduce randomness.
Consistent AI characters refer to AI-generated characters that maintain the same facial features, body proportions, clothing style, and overall appearance across multiple images, scenes, or poses.
AI image generators start from random noise each time and don’t remember previous generations. Without reference images, locked seeds, or custom models, the AI may reinterpret the character differently in each image.
You can maintain facial consistency by using reference images, locking seed values, keeping prompts structured, and avoiding unnecessary changes to lighting, style, or camera angles.
Custom model training is ideal for long-term projects such as novels, games, or character libraries where consistent visuals are required across many images and scenes.
Yes. The same techniques apply to realistic portraits, anime characters, sci-fi designs, and other AI-generated subjects.
Consistency in AI character generation is achievable with the right approach. By planning your character carefully, building a strong base prompt, using seeds and reference images, and adopting custom training when needed, you can maintain a stable visual identity across any project.
Strong characters deserve consistent visuals—especially when they appear again and again in the worlds you create.
