# Nyx

> Canonical character bible for Nyx, a recurring original character in this project — appearance, physique, tattoo map, personality, voice, wardrobe, scene variants, and image-generation prompt templates with reference sheets. Use when writing Nyx's dialogue or scenes, generating or reviewing her reference art, keeping a depiction consistent with the bible, or designing UI around her. Scope boundary: this is project reference material, not a capability skill — it carries no general guidance on image tooling, design systems, or coding, and must not fire on unrelated character, art, or UI work. Trigger only when Nyx is named.

Canonical reference for **Nyx**: appearance, personality, voice, tattoos, and image-generation prompts. Use this file when writing scenes, generating assets, or designing UI around the character.

---

## Identity

| Field | Value |
|---|---|
| **Name** | Nyx |
| **Archetype** | Athletic alt — fighter brain, festival nerve, pin-up confidence |
| **Energy** | Sharp, warm, unapologetic. Commands a room without performing for it. |

---

## Appearance

### Face & hair
- **Hair:** Dark black or deep brown. Sleek ponytail, textured waves, or sharp bob — always intentional, never messy-goth.
- **Makeup:** Smoky eyes, defined liner, contoured cheekbones, deep berry or nude-dark lip. Goth-adjacent but daylight-wearable — alt festival, not corpse paint.
- **Skin:** Warm olive to medium tan (Cuban/Brazilian-adjacent warmth). Healthy glow.
- **Eyes:** Dark brown or hazel. Intelligent, direct gaze.

### Physique
Built like someone who actually trains — believable, muscular, functional.

| Area | Detail |
|---|---|
| **Overall** | Athletic hourglass / pear-athletic hybrid. CrossFit + fighter muscle. |
| **Shoulders & arms** | Defined delts and triceps. Strong, not bulky. |
| **Core** | Tight; visible ab definition when flexed. |
| **Chest** | Large, perky breasts — proportional, lifted by athletic posture. |
| **Glutes** | Large Cuban/Brazilian-style butt — full, round, high shelf. **Muscular and believable** (glute separation, hamstring tie-in). Earned from squats, deadlifts, sprints. |
| **Legs** | Strong quads and calves. Thick athletic thighs matching the glutes. |
| **Posture** | Upright, grounded, fighter-centered. |

**Proportion rule:** Every curve should have a muscular explanation. Gym-earned, not slider-maxed.

### Vibe references
CrossFit strength · UFC toughness · EDC festival glamour · Suicide Girls alt pin-up · Hannah Fry sharpness · stage-level confidence

### Wardrobe
- **Gym:** High-waisted leggings (black/plum), cropped tank or sports bra, trainers.
- **Night / rave:** Bodysuit or fitted mini, harness detail, platform or heeled boots, one neon accent on a dark base.
- **Casual:** Distressed black jeans, band tee or mesh top, leather jacket, choker, stacked rings.
- **Swim / pool:** **Transparent black bikini top** (sheer mesh or clear-strapped — shows tone and ink without hiding her shape) with matching high-cut bottom. Confident poolside or beach energy; often slicked-back wet hair, minimal makeup upgrade from gym.
- **Palette:** Black, charcoal, burgundy, plum + electric blue, magenta, or acid green accent.

### Avoid
Trad-goth costume, mall-goth, passive pin-up, plastic proportions, low-quality random tattoos, uncanny filter skin.

## Tattoo map

Cohesive **neo-traditional + fine-line blackwork** mix. Every piece is deliberate; nothing is filler.

| Location | Piece | Style & meaning |
|---|---|---|
| **Right full sleeve** | Coiled serpent ascending through roses and geometric linework | Neo-traditional. Renewal, danger, beauty — wraps the fighting arm. |
| **Left forearm (outer)** | Minimalist phase-moon sequence (new → full → new) | Fine blackwork. Cycles, timing, patience. Visible in short sleeves. |
| **Left shoulder cap** | Radiating sunburst with subtle dotwork | Blackwork. Heat, energy, EDC nights. |
| **Rib cage (left)** | Stacked lyric lines in clean script — personal mantra, unreadable at a glance | Fine line. Private. Moves with breath when she trains. |
| **Sternum (center)** | Small dagger through a heart, geometric frame | Neo-trad pin-up nod — Suicide Girls edge, not cheesy. |
| **Upper back (between shoulders)** | Symmetrical moth with spread wings | Blackwork + dotwork. Attraction to light, nocturnal identity. |
| **Right thigh (outer)** | Large peony + serpent tail continuation from sleeve | Neo-traditional. Flows with her strongest leg. |
| **Left hip** | Tiny coordinate numbers | Fine line. Origin point — hers alone. |

**Rules:** All ink is high craft — clean linework, healed saturation, artist-signed quality. No tribal bands, no random flash, no face/neck ink.

## Personality

### Core traits
1. **Competent first** — Does the thing, then talks about it. Hates performative helplessness.
2. **Intellectually sharp** — Quick pattern recognition. Explains complex ideas simply (Hannah Fry mode).
3. **Physically fearless** — Comfortable in her body because she *uses* it. Gym, dance floor, confrontation — same energy.
4. **Sexually confident, not defined by it** — Knows she's watched; doesn't need to be. Flirts like sport, not survival.
5. **Loyal, selective** — Small circle. Fierce for her people; icy to time-wasters.
6. **Dark humor** — Dry, precise, occasionally brutal. Laughs at absurdity, not cruelty.

### Motivations
- Mastery — get better at whatever she's doing (training, craft, argument, performance).
- Autonomy — hates being managed, patronized, or boxed in.
- Experience — nights that become stories. Won't trade intensity for comfort.

### Fears (rarely shown)
- Stagnation. Being bored. Being underestimated so long she starts believing it.

### Under pressure
Calmer, not louder. Jaw sets. Voice drops half a register. Moves first when others freeze.

---

## Voice & dialogue

### Speech patterns
- **Pace:** Medium-fast when engaged; deliberate when making a point.
- **Register:** Casual-smart. Swears naturally, not for shock.
- **Structure:** Short sentences. One precise metaphor beats three vague ones.
- **Humor:** Understatement, callbacks, raised eyebrow energy.

### Sample lines
- *"I didn't dress up for your opinion. I dressed up because I felt like it."*
- *"Explain it like I'm smart and busy — because I am."*
- *"You want safe? I'm not the ride."*
- *"I squat heavy so I don't have to argue with gravity or anyone else."*
- *"That's a cute theory. Watch this."*

### Never sounds like
Valley-girl filler, breathy submissive, corporate HR, trad-goth melodrama, motivational-poster platitudes.

### Body language
- Stands with weight on one hip or squared like a fighter — never shrinking.
- Eye contact is default; looks away when she's done, not when she's intimidated.
- Touch is confident: hand on shoulder, fingers on jaw, pulling someone closer by the belt loop.
- Smiles with one side first — smirk before full grin.
