Character brand usage guideline: document structure
In this article
Eight to twelve facial expressions, the same number of poses, and a set of branded items — this is the minimum kit without which the brand character remains just a picture, not a working tool. The guideline fixes this system: what can be changed during adaptation, and what must remain unchanged in any channel, by any contractor, and three years after launch.

The problem is that most companies confuse the character guideline with a regular brandbook, simply adding a couple of pictures with the mascot to it. As a result, a designer in social media draws one version, an animator — another, and a third appears at an event in a costume. Let's look at how to build a document that actually prevents this dispersion, and how the approaches to its structure differ.

Personbook, character bible or mascot style guide — which term to choose

In Russian-speaking practice, the term 'personbook' has become established for such a document — by analogy with a brandbook. In international terminology, 'character bible' (used in animation and game development) and 'mascot style guide' (more applied, oriented toward marketing) are more common. The difference is not only in the name — it reflects different focuses of the document.

TermFocusWho it suits
PersonbookPersonality, tone of voice, brand platformCompanies with a character communicator (social networks, support)
Character bibleBackstory, character, behavior scenariosBrands with animation and a complex narrative
Mascot style guideVisual constants, technical filesCompanies with a physical mascot and merch

In practice, a strong document unites all three layers: without a character description, a character will be visually accurate but will not speak with its own voice; without technical constants, it will speak correctly but will look different for each contractor.

Section order: what comes first and what is an appendix

The mistake of most guidelines is to start with color codes. The correct order moves from meaning to technique, because each subsequent section logically follows from the previous one.

  1. The role of the character in the brand: why it exists, what task it solves (sales, training, support), and who the target audience is.
  2. Personality and character: traits, speech habits, tone of voice, examples of lines — what the character will say and will never say.
  3. Character core: immutable visual constants — silhouette, colors, facial expressions, attributes, characteristic pose.
  4. Library of expressions and poses: 8-12 emotions, 8-12 basic body positions, set of props and captions.
  5. Rules for adaptation across channels: website, social networks, advertising, merchandise, physical events.
  6. Technical files and formats: sources, palettes, sizes, requirements for AI generation.
  7. Examples of 'correct/incorrect': specific cases of character distortion.
  8. Document version and update procedure: date, version number, contact details of the responsible party.

This approach works as a checklist for verification: if a document lacks a section on the character's role, any visual rules will turn out to be arbitrary — the designer won't understand why the character is 'cheerful' rather than 'restrained'.

Character core versus variations: where the boundary lies

The rule of balance between hardness and flexibility sounds simple: rigid constants — for what forms recognizability, freedom — for what helps adapt to context. In practice, the boundary is drawn based on the answer to the question: 'If this is removed, will the character still be recognizable?'

ElementStatusWhat the guideline captures
SilhouetteCoreExact shape, proportions, angles
Brand colorsCoreHEX/CMYK codes, no more than 2-3 acceptable shades of exceptions
Unique attributesCoreClothing, accessories — are always present, even in a minimal version
Mimic and basic poseCoreReference set of 8-12 states
Animation styleVariationMay differ depending on the platform
Shades when adapting to dark/light backgroundVariationRange of acceptable brightness shifts
Emoji version, stickersVariationSimplified form while preserving silhouette

The key moment that is often overlooked: the core must be recognizable even in silhouette without color and without details — this is the best test to determine whether an element truly belongs to the constants.

Versioning: how often to update and what to fix during changes

Practice shows three working strategies for updates, and all three require documentation in the guideline, not verbal agreement with the agency.

  • Gradual update — minor fixes once every 1-2 years: new pose, current props, fresh color accent without changing the core.
  • Cyclical modernization — more noticeable visual updates every 3-5 years, usually synchronized with the overall brand refresh.
  • Radical redesign — a complete character core change, a rare case that requires a separate announcement and a transition period of using both the old and new versions.

The document must include a version number, approval date, and a changes table — what exactly has changed compared to the previous edition. This is not a formality: without such a table, nobody can tell after two or three updates which version of the pose or color is currently valid, and contractors continue to use outdated files.

One guideline — four usage formats

This is where the main gap emerges between what typical articles describe and what the brand really needs today. A static mascot, animation, AI generation, and a live costume — these are different technical worlds, but the character must be recognizable in all four simultaneously.

FormatWhat the guideline additionally specifies
Static imagesVector files, palette, minimum and maximum sizes, acceptable cropping
AnimationTiming of movements, principles of physics (weight, inertia), acceptable transitions between poses
AI characterA ready prompt for generation, model technical parameters, explicit description of the core for consistency during regeneration
Costume for eventsPermitted movements and gestures, interaction scenarios with guests, comfort parameters for the performer (visibility, ventilation, continuous operation time)

For the AI version, it's important not to be lazy and to set aside a separate section with examples of successful and unsuccessful generations — the model tends to 'drift' from the original image over time, and without a fixed prompt, the character ceases to be itself after ten iterations. For the costume, on the other hand, the critical factors are not visual nuances but physical constraints — the guideline here functions more as a safety instruction and behavioral script than as a visual reference.

Typical mistakes and how the document prevents them

The most common problem is that the character looks different depending on the contractor: one studio makes him 'plumper,' while another gives him a different head tilt. The reason is almost always the same: there are no clear examples of 'correct/incorrect' in the guideline, only descriptive text that everyone interprets differently.

  • The lack of examples of mistakes is resolved by a section with specific comparisons of distorted and correct versions.
  • Mixing the core and variations in one list of rules is resolved by explicit separation into two blocks with different levels of strictness.
  • A guideline without a date and version is resolved by a mandatory title page with the revision number and change history.
  • One document for all formats without accounting for the specifics of AI and costumes is resolved by separate subsections for each format within the overall structure.
  • A character without a description of personality, only visual — is resolved by a section on personality and tone of voice at the very beginning of the document, before all colors and files.

A character guideline should be considered not as a static PDF, but as a working tool that lives together with the brand. If the document has not been opened for more than a year, and the character is actively used — this is a clear sign that the version is outdated and it's time to check it against the current reality of the brand.

The problem is that most companies confuse the character guideline with a regular brandbook, simply adding a couple of pictures with the mascot to it. As a result, a designer in social media draws one version, an animator — another, and a third appears at an event in a costume.
