FAILHORROR — NULO Character Bible v1.0

DECISIONES APROBADAS Visor industrial envejecido; terror realista e inquietante; símbolo circular incompleto.

IDENTIDAD NULO es un perseguidor urbano silencioso, originario de la ficticia Santa Vela, al norte de México. Nadie conoce su rostro ni su identidad. Nunca habla y nunca actúa como comediante.

DISEÑO Casco integral industrial negro envejecido, visor ahumado opaco sin ojos visibles, círculo incompleto gris gastado al centro. Chaqueta de trabajo carbón con costura reflectante diagonal, guantes, pantalones utilitarios y botas industriales oscuras. Aro de seis llaves antiguas en la mano izquierda.

ACTUACIÓN Camina lentamente, de forma metódica. Ante una interrupción se detiene dos segundos (The NULO Pause). La comedia nace de la vida cotidiana, no de que NULO actúe de forma torpe.

NULO_TEST_001 — PLAN DE GENERACIÓN HIGGSFIELD (2026-10-09) OBJETIVO: Verificar continuidad facial (visor), símbolo, traje, llaves y microactuación con plano fijo de 8 segundos. Estado: LISTO PARA GENERACIÓN / NO RENDERIZADO. INPUT: Utilizar NULO_V2_01_FRONT_PREVIEW.png del ZIP de Drive como referencia provisional. Priorizar primera prueba a 9:16, 1080x1920 si disponible. No declarar este recorte como referencia definitiva. Exportar mp4 sin texto. PROMPT VIDEO (ENGLISH): A single locked-off medium-wide cinematic shot at night on a realistic residential street in northern Mexico. NULO, the identical tall urban stalker from the supplied reference image, wears the same aged matte-black industrial full-face helmet, opaque smoked visor with the same distressed incomplete-circle mark, dark charcoal work jacket with one worn diagonal reflective seam, black gloves, cargo trousers and heavy boots. Exactly six old mismatched keys hang from a single metal ring in his LEFT hand. He stands under a warm amber streetlamp on damp pavement and looks toward a house off screen. For the first two seconds he remains motionless. A small dog barks once off screen. He turns his helmet slightly, about 15 degrees, toward the sound, then freezes completely for the final two seconds. Grounded realistic live-action horror, tense and restrained, subtle cold fill light, ambient street haze. Continuous single shot, no camera movement, no zoom, no cuts, no dialogue, no text, no face reveal, no weapon, no slapstick. NEGATIVE CONSTRAINTS: no visor transformation, no extra limbs, no key duplication, no changes of outfit or markings, no helmet opening, no neon eyes, no robot appearance, no comedic dance, no jump cuts, no excessive rain, no camera orbit. TIMING: 0–2s freeze; 2–4s offscreen dog bark and subtle recognition; 4–6s ~15 degree helmet turn; 6–8s The NULO Pause, motionless. Audio may be added in post if generator cannot time it. POST AUDIO: 0s faint urban night ambience; 2.5s single distant small-dog bark; 4s tiny metal key rattle; 6s ambience drops slightly; 8s hard cut. No music until visual QC passes. QC GATES: (1) symbol stays at front of visor, (2) 6 keys remain one ring, left hand, (3) face remains fully hidden, (4) jacket seam and helmet silhouette consistent, (5) five fingers each hand, (6) stable shot and lighting, (7) neck turn believable, (8) two-second final pause. Record pass/fail with notes. OUTPUT NAMING: NULO_TEST_001_MODELNAME_v001.mp4; sidecar .txt with prompt, input image filename, model, settings, date, credits, operator, rights. Limit to 3 exploratory generations before diagnosing failure. If model cannot keep keys stable, shoot a medium crop without keys and insert a separate key-detail shot later; document this as a non-canonical workaround. RESPONSIBILITIES: Video lead=generate; Art lead=inspect costume/symbol; Audio lead=foley; Producer=archive and record licensing; Showrunner=final visual approval. HIGGSFIELD CONNECTION: Available integration discovered but not yet installed/connected. Requires account connection before ChatGPT can launch the model directly.

DECISIÓN DE PRODUCCIÓN APROBADA — 09 OCT 2026 Coordinación editorial, dirección creativa, prompts y control documental: ChatGPT con GPT-6 (el equipo lo denomina Astra).

Estado de la integración Runway: conexión de cuenta pendiente de autorización por usuario. No afirmar que NULO_TEST_001 está renderizado hasta recibir un archivo o resultado verificado del generador. Próximas acciones: 1) conectar Runway en ChatGPT; 2) abrir paquete de 9 referencias NULO v2 en Drive; 3) crear animación de 8 s con referencia frontal y prompt NULO_TEST_001; 4) comprobar ocho criterios QC; 5) guardar resultado y observaciones en Drive; 6) definir la imagen maestra definitiva tras la prueba. Responsables: dirección creativa GPT-6 + aprobación humana; operador de video Runway; arte supervisa consistencia; sonido y montaje en post; producción archiva masters, prompts y permisos.

Master image prompt (EN)

Original grounded cinematic Latin American horror design: NULO, human urban stalker. Worn matte-black industrial full-face helmet, opaque smoked visor, distressed incomplete gray circle at the center; charcoal work jacket with a diagonal reflective seam, black gloves, dark utility trousers and heavy boots. Exactly six mismatched old keys on one ring in the LEFT hand. Scale: Tall silhouette; exact height not previously established. Palette: charcoal #282B2C, black #111313, worn gray #777A76. Physically plausible photographed materials, serious restrained presence, no humorous pose. Neutral lighting, isolated full silhouette or location plate for a bodiless phenomenon, 10 percent empty margins, no collage, no text, no brands. Preserve every defining feature from the identity reference. New production measurements are design proposals. Exactly six mismatched old keys in LEFT hand. Keep face hidden behind the same opaque visor. Never close the incomplete circle.

12 / PRODUCTION SHEET

8-second performance test (EN)

Single locked-off eight-second realistic cinematic shot, vertical 9:16. Use the approved master when available; until then label output exploratory. Character or phenomenon: NULO. Worn matte-black industrial full-face helmet, opaque smoked visor, distressed incomplete gray circle at the center; charcoal work jacket with a diagonal reflective seam, black gloves, dark utility trousers and heavy boots. Exactly six mismatched old keys on one ring in the LEFT hand. For 0–2 seconds NULO stays still. At 2 seconds an off-screen small dog barks. During 2–6 seconds the helmet turns approximately 15 degrees toward the sound. During 6–8 seconds he freezes completely. Exactly six keys stay on one ring in the LEFT hand; opaque visor and incomplete circle never change. Warm motivated street light with soft cool fill. Continuous shot. The action must be understandable with the sound muted. No dialogue, no text, no lip-sync, no comedy performance; the everyday interruption carries the humor. Keep identity, scale, anatomy, costume, palette and prop count stable.

13 / PRODUCTION SHEET

Generation constraints (EN)

No dialogue, captions, speech bubbles, readable text, lip-sync, comic dance, cartoon rendering, celebrity likeness, borrowed franchise design, gore, extra limbs, identity morphing, outfit changes, duplicated props, mirrored handedness, camera orbit, jump cuts or uncontrolled zoom.

14 / PRODUCTION SHEET

Sound and silent comprehension

Original task or material foley; restrained local ambience. No dialogue, vendor calls or franchise music. Sound may reinforce the beat but must not explain it. Test comprehension with sound off.

15 / PRODUCTION SHEET

Quality control

1 Stable identity/shape; 2 silhouette and scale; 3 materials/palette; 4 props and handedness; 5 anatomy or VFX layers; 6 camera and light; 7 serious performance; 8 meaning understood without audio or text.
