First Web — An AI-Built Marvel Roleplay (Gwen Stacy's Origin)

Stage 1: World Buildingdeepseek-v4-flash
The world “Untitled World” set the house direction — clean hard-shadow cel illustration, readable simplified volumes, controlled outlines and flat local color, with a present-day Marvel Universe, teenage superhero adventure, grounded slice-of-life and lasting consequences. From a single world prompt the AI built the long-form overview, the core conflict, fifteen characters, four places, two lore items and the rules that keep canon bendable.

Stage 2: Roleplay & Story Draftingdeepseek-v4-flash
From a one-line premise the agent wrote the playable spine of First Web: the morning-after opening beat, the central conflict between Gwen’s ordinary life and the changes she cannot interpret, five investigable threads (body anomaly, bite source, ordinary life, city pressure, Warren interest) with clues, actions, discoveries and consequences, a nineteen-edge relationship graph and the Create Your Gwen opening screen.

Stage 3: Character Portrait Artgpt-image-2
Each of the fifteen characters was painted as a vertical card in the world’s own cel-shading style — Gwen in her hoodie and striped tee, Peter with his camera and glasses, Warren with his Oscorp badge and tablet, George in uniform, Mary Jane with her guitar case, Felicia with her bass — so every character keeps one consistent, believable face across the world.

Stage 4: Scene & Location Artgpt-image-2
New York was painted as scene and location art: the Midtown High School exterior, the Stacy home, the Mary Janes warehouse rehearsal room and the city street, plus key cinematic frames such as The Leap and the Sirens night sidewalk — backgrounds with the lower third kept calm for dialogue and scene cards.

Stage 5: Transparent Cut-Outbirefnet-general
Each character card was background-removed with BiRefNet into a true transparent PNG, so Gwen, Peter, Warren, George, Mary Jane and Felicia composite cleanly over any painted scene without a white box — at school, at home, in the warehouse or on a rooftop.

Stage 6: Visual QA & One-Click Publishneta-studio
The build was checked in-browser — scene framing, sprite scale, text contrast in dark and light, the Start Adventure flow and the live scene-media layout — then published in one click to a shareable play link, with the world’s portraits, scene art and prompts left reusable by any fork.

First Web — The Leap · Action-Scene Promptgpt-image-2
"@Gwen Stacy, @Peter Parker, Create a cinematic action-scene cel illustration for the Marvel teen superhero adventure 'First Web'. Scene: a sunlit mid-morning New York City street, crosswalk and parked cars along the curb. Sixteen-year-old Gwen Stacy — shoulder-length blonde hair with soft pink-gradient tips, blue eyes, grey zip-up hoodie over a blue-and-white striped t-shirt, dark blue jeans, black high-top sneakers — was crossing the road mid-block, distracted talking with Peter, when a car nearly hit her. The tingle fires and her body moves before thought: she is airborne in a low reflexive flip, somersaulting high over the car's hood, clearing the vehicle by several feet, hoodie flaring, hair swept upward, eyes wide with startled surprise at her own impossible leap. Beneath her a yellow taxi sedan brakes hard, nose dipping, the driver gaping through the windshield. On the far sidewalk Peter Parker — dark brown tousled hair, thick black glasses, dark grey zip-up hoodie over a maroon t-shirt, film camera on a strap, backpack — has spun around mid-stride, mouth open in alarm, one hand rising. A few pedestrians on the corner turn to stare. Composition: dynamic low three-quarter angle, wide landscape frame, Gwen frozen at the apex of her flip as the clear focal point against the sky, strong diagonal energy, subtle motion lines, hard-edged cel-shadow shapes raking across the street under simple morning sunlight, clean controlled outlines with consistent silhouette hierarchy, broad flat local colors in discrete value steps, smooth low-texture fills, compact graphic highlights. Keep Gwen's and Peter's designs consistent with the reference images. Constraint: no readable text, no logos, no watermarks, no captions, no speech bubbles. Style: clean hard-shadow cel illustration."

First Web — Sirens · Night-Scene Promptgpt-image-2
"Create a cinematic wide 16:9 opening frame for an animated sequence in a grounded teen superhero drama. Style: clean hard-shadow cel illustration — clean controlled outlines with a clear silhouette hierarchy, broad flat local colors in discrete value steps, one or two hard-edged cel-shadow shapes under simple light logic, smooth low-texture fills, compact graphic highlights. Scene: a New York City sidewalk at night outside an old athletic center, wet asphalt reflecting light, a brightly lit twenty-four-hour laundromat window on the left, an ambulance and a police car at the curb with red-and-blue emergency lights strobing across the street. In the lower-left foreground, seen from behind and slightly to the side, a lean sixteen-year-old girl in a homemade mostly-white wrestling-style suit — white fitted hoodie with the hood up, white knit full-face mask with uneven hand-cut eye holes ringed in shaky hot-pink web lines and a pair of blue eyes showing through, a large hand-painted hot-pink spider on the chest with paint drips, white leggings with wobbly blue stripes, baby-blue fingerless gloves, white high-top sneakers with pink laces — has stopped dead mid-step, shoulders rigid, one gloved hand frozen mid-motion. Beside her a sixteen-year-old boy in a dark grey zip-up hoodie and thick black glasses has turned toward her, one hand rising toward her arm, face pale with alarm. Ahead down the sidewalk two EMTs in dark uniforms kneel over a woman in a long coat lying on the ground — one performing chest compressions, the other squeezing a ventilation bag; a dropped handbag rests near the curb and a single shoe lies several feet away near the crosswalk; a police officer holds a small crowd back at the edge of the frame. Composition: wide landscape frame, medium-wide shot, the two teenagers anchored in the lower-left foreground, the emergency scene receding down the sidewalk ahead of them, emergency-light color washing the wet pavement, hard cel shadows. Constraint: no readable text, no logos, no watermarks, no captions, no speech bubbles."

First Web — Nightfly · White Widow Promptgpt-image-2
"@White Widow V1, Create a cinematic action-scene cel illustration for the Marvel teen superhero adventure 'First Web'. Scene: night over midtown Manhattan. White Widow V1 — Gwen Stacy's hooded white-and-charcoal handmade prototype suit, hood worn up over the full-face mask, pale baby-blue angular lenses with a thin hot-pink inner edge, small hand-painted pink spider at the center chest, asymmetrical charcoal panels on one shoulder, the torso sides, one forearm, the thighs and lower legs, charcoal gloves and boots, compact matte-white and charcoal mechanical web-shooters on both wrists — rockets low and fast along an open avenue, the instant after a near-ground dive. She has just come out of a steep plunge and is swinging parallel to the street, body stretched into a long athletic arc, one arm flung back gripping a taut web line that catches the light, the other arm trailing, legs swept behind her in a dancer's line, hood and fabric snapping in the wind. Her silhouette is lean, narrow-shouldered, and unmistakably a slim teenage girl, not a bulky hero. Below her the asphalt rushes past close enough to blur: a yellow taxi swerving, crosswalk stripes, tail lights smearing into red streaks, storefronts and street lamps throwing pools of warm gold, midtown traffic reduced to long light trails. The darkening city climbs into a canyon of lit windows around her; the Empire State Building rises in the distance, its upper floors glowing against the deep blue night, Times Square's far-off glow scattered along the avenues; somewhere a siren's red wash tints a wet crosswalk. Her body reads calm, weightless, and exultant — the freedom of flight she just named as her own. Composition: dynamic low three-quarter tracking angle, wide landscape frame, the low horizontal rush of the street leading the eye, strong diagonal momentum from the web line through her body, subtle motion lines, motion-blurred light streaks on the ground, White Widow as the clear focal subject against the dark canyon of buildings, restrained background detail. Style: clean hard-shadow cel illustration, crisp controlled outlines with consistent silhouette hierarchy, broad flat local colors in discrete value steps, one or two hard-edged cel-shadow shapes under simple directional light, smooth low-texture fills, compact graphic highlights. Keep White Widow V1's design consistent with the reference images. Constraint: no readable text, no logos, no watermarks, no captions, no speech bubbles, no other characters, no Peter Parker, no unmasked face."

Gwen — Unmasked White Widow · Character Promptgpt-image-2
"Clean hard-shadow cel-shaded full-body character portrait of Gwen Stacy wearing her original White Widow V1 field suit without a mask. Gwen has a slim, lean, long-limbed build, narrow shoulders, bright blue eyes, and shoulder-length blonde hair fading into soft pink ends. Her entire face is visible, with a calm determined expression and a trace of grief. A functional white hood is still worn up behind and around her head, while her blonde-and-pink hair spills naturally around her cheeks and shoulders. The mask is completely absent. The full-coverage handmade prototype suit is mostly matte white with original asymmetrical charcoal-black panels across one shoulder, both sides of the torso, portions of the thighs and lower legs, plus charcoal gloves and boots. A small simple hand-painted pink spider sits at the center chest. Restrained pink forearm panels and tiny baby-blue edge accents break up the white. Practical dark seams and reinforced patches show that Gwen and Peter built it rather than a costume company. No web patterns, no large emblem, no classic canon spider-suit shapes, no visible web-shooters. Neutral relaxed protective stance, arms resting naturally, full figure centered from hood to boots, simple cool-gray studio background. Clean controlled outlines, broad flat colors, discrete cel-shadow steps, no text, no logos, no watermark, no extra characters."
