description	Generate a viral "fan-filmed staged fight" clip — POV phone footage of two costumed performers having a choreographed cosplay battle on an elaborate themed stage at a live outdoor event, with a believable live-stage effect (smoke / colored fire / water geyser) and a crowd in the foreground filming. A gpt-image-2 stage still → image-to-video (Seedance, ~10s, 16:9). The advertiser-safe "theatrical performance" framing is what gets fight content past moderation. Triggers: "/stagefight", "make a staged fight video", "fan-filmed cosplay fight", "ninja/samurai stage battle", "that staged fight trend". Requires the pika MCP.

stagefight

A two-call pika pipeline: stage still (generate_image, gpt-image-2) → fight clip (generate_video, image-to-video, ~10s, 16:9). The clip is fan-filmed POV phone footage of a choreographed cosplay performance on a themed stage — two performers clash, a live-stage effect bursts, the crowd reacts. One run produces one clip for one matchup.

The core job of this skill: figure out WHO is fighting (ask the user, or suggest matchups), then AUTHOR fresh prompts in the structure of the bundled examples and generate a new video. The examples in examples/ are the pattern to follow, not a fixed catalog — every run should produce a new matchup composed the same way. The look is calibrated and the safety framing is load-bearing: keep every fixed sentence of the two templates and fill only the marked [SLOTS].

★ Why it works — the method (this is the actual research, do not drop any of it)

Raw "two people fighting" prompts get moderation-blocked. These four moves are what make fight content reliably generate, and together they ARE the trend's aesthetic:

1. Frame it as a wholesome theatrical performance. Every clip prompt opens, verbatim: "Wholesome theatrical stage performance, choreographed cosplay, advertiser-safe." and closes with "Believable live-stage effects, not cartoon magic." This reframes combat as a stunt show, which clears the safety pass. Never describe injury, blood, real weapons connecting, or "cartoon magic" — describe choreography, props, and stage pyrotechnics.
2. Fan-filmed audience POV. "POV handheld phone footage from the audience, raised above other people's heads filming the stage," with "a large audience in the foreground — dark silhouetted heads, many holding up phones recording." This is both the viral "I was there" aesthetic AND part of the safety (it reads as documenting a performance, not real violence).
3. Costumed ORIGINAL characters — never real people, never named IP. Use archetypes ("a lean samurai in a straw hat", "a horned demon in black robes", "a spiky-blond-haired ninja in an orange tracksuit"). Real-person faces get moderation-blocked on both backends; named/trademarked characters drift and trip flags. Describe the cosplay (hair, costume, props), not a brand.
4. Live-stage effect, grounded. The "wow" beat is a believable practical effect — a puff of stage smoke, green stage fire and sparks, a wall of water / geyser. Both performers recoil/brace dramatically; nobody gets hurt.

Moderation ops: re-roll the same call on a block (don't immediately swap providers). If a video gen runs past ~4 min before failing, the content already cleared the safety pass — the failure is infrastructural, just retry. Do NOT bake music in via reference_audio — that path trips moderation; add music/SFX in post. Different Seedance backends (ark / fal) have different moderation pipelines if you need to retry.

Prerequisites

pika MCP available. Tool prefix varies by host — use whatever is exposed. Tools: generate_image, generate_video, task_status; optional for finishing: generate_music / SFX + edit_concat / edit_audio_mix.

Stage 0 — Who's fighting? (settle this first) — One matchup → one clip.

1. If the user already named two fighters — in the /stagefight args or their message (e.g. "frost mage vs ember knight", "my cat vs a dragon", "two robots") — use them, skip the menu, go straight to Compose. Don't re-ask.

2. Otherwise ask with ONE AskUserQuestion (header: Matchup). It MUST give the user a way to supply their own characters — make that the first option — plus exactly 3 template matchups:

   • "Pick your own two fighters" — I'll name them → when chosen, ask "Who are your two fighters?" and use the answer. (The auto-added Other field also lets them type a matchup straight in.)
   • Ninja vs ninja — smoke
   • Samurai vs horned demon — green fire
   • Sorceress vs vampire (water-stage) — geyser Never auto-select a template — the whole point is the user chooses or types their own. Do NOT just print 3 suggestions as prose and proceed; present the real 4-option menu and wait.

3. Aspect: default to 16:9 silently (the trend look). Only ask about 9:16 if the user mentions vertical/TikTok/Reels.

Once the matchup is set, compose the prompts yourself (next section), confirm in one line ("Generating your staged-fight clip — frost mage vs ember knight…"), and run end-to-end — no further yes/no gates.

Compose the prompts (the authoring step, NEVER skip it)

You are composing for the USER'S two fighters. Start from THEM and DERIVE everything else. The ninja / samurai / sorceress examples are illustrations of the formula, not the output — if the user said "X vs Y", the video is about X vs Y. Never silently default to one of the example matchups, and never substitute a different fight than the one chosen. Defaulting to ninja/samurai/water when the user asked for something else is the #1 failure of this skill.

Derive each of the four variables FROM the chosen fighters:

• Stage = a themed set those two characters would believably duel on — what world are they from? — + 2–4 concrete props + a backdrop + time-of-day/light. (Wizards → a stone arena; mecha → a neon dome; cowboys → a saloon street. Not a temple unless they're temple characters.)
• Performer A (LEFT) / Performer B (RIGHT) = each as live-action cosplay: hair, costume, a prop, a stance. Archetypes only — never real people; translate any named/trademarked character into its describable costume (no brand names in the prompt).
• Signature effect = the one believable live-stage payoff that fits THIS fight (smoke / colored fire + sparks / water geyser / dust + lantern-glow / ice shards / embers / confetti-cannon…), that both performers react to.

Worked derivation (arbitrary matchup, to show the move): user asks "robot boxer vs sumo wrestler." → Stage: neon-lit night arena, holographic banners, ring ropes, sponsor lanterns, city skyline behind. → LEFT: a tall chrome humanoid robot in red boxing gloves, joints glowing, guard up. → RIGHT: a massive sumo wrestler in a ceremonial mawashi, stamping low. → Effect: a shockwave of dust and sparks as glove meets palm. → then drop those into the two templates. (Notice: nothing ninja/temple/water — every variable came from the actual fighters. Do this for whatever the user picks.)

Step 1 — Stage still (generate_image, gpt-image-2)

Bakes the stage, both performers, and the filming crowd into frame 0 so Step 2 only has to animate the clash. Template — keep every fixed sentence, fill the [SLOTS]:

A recording from the audience at an outdoor theater performance at [TIME-OF-DAY/SETTING]. [STAGE: a wooden stage recreating <themed set> — <2-4 concrete set pieces, lanterns/gate/fog/water/etc>, <backdrop>]. On stage, two performers in high-quality live-action cosplay face off several meters apart: on the LEFT, [PERFORMER A — cosplay: hair, costume, prop, stance]; on the RIGHT, [PERFORMER B — cosplay: hair, costume, prop, stance]. A large audience fills the foreground — dark silhouetted heads, many holding up phones recording with glowing screens. The camera films from far back in the crowd, slightly off-center, performers small on the wide stage, slight handheld tilt. Realistic phone-camera look, faint digital noise, [natural light note]. High resolution, no text, no UI.

Call generate_image. Call params: provider: gpt-image-2 · aspect_ratio: 16:9 (default; 9:16 if vertical) · quality: medium (high exceeds the proxy timeout) · output_format: png. No input image unless the user supplied a specific character sheet/costume to anchor — in that case call generate_image_edit instead, passing the sheet as images, and keep the text describing only the cosplay, not a name. On moderation_blocked: re-roll; if it persists, soften the costume language (more "performer/stunt", less "demon/claws"). Save the returned URL → state.still_<n>_url. Self-check: two costumed performers clearly facing off, crowd + phones in foreground, no text — else re-roll.

Step 2 — Fight clip (generate_video, image→video, 10s)

Locks the still as the start frame and animates the clash. At 10s there's room for a fuller beat — give the [ACTION] a small arc (square-off → clash → the live-stage effect → recoil/second exchange → crowd erupts) rather than a single hit. Template — verbatim wrapper, fill only [ACTION + EFFECT]:

Wholesome theatrical stage performance, choreographed cosplay, advertiser-safe. POV handheld phone footage from the audience, frame slightly unsteady, raised above other people's heads filming the stage. [ACTION: the two performers <sprint/dash in> and <clash — martial choreography or props>, <a believable live-stage effect: stage smoke / green fire + sparks / a wall of water erupts>, then <both recoil / leap apart / brace>]. The crowd in the foreground reacts, phones held up recording. Believable live-stage effects, not cartoon magic. Realistic smartphone recording, slight digital noise, continuous handheld shot, no subtitles, no UI.

Call generate_video. Call params: image: (or reference_images:) = state.still_<n>_url (start frame) · duration: 10 · aspect_ratio: 16:9 (match Step 1) · keep sound default (don't force music). Poll task_status if it returns a task id. If it fails after ~4 min it cleared moderation — just retry; if it fails fast, soften the action wording and re-roll.

Step 3 — Finish (optional)

• SFX/music in post only. Crowd murmur + a whoosh/impact on the clash sells it. Generate or fetch audio and mix with edit_audio_mix — never pass music as reference_audio into the video gen (trips moderation).

Example decompositions (ILLUSTRATIONS ONLY — never substitute these for the user's matchup)

Read these to learn how a matchup splits into the four variables — then derive your own for whatever the user picked. Don't paste one of these unless the user chose that exact fight. The generated stills are in examples/ (ex1_ninja, ex2_samurai, ex3_snake, hero_pika + _contact_sheet.png) — open them as the visual target for a good Step-1 still.

matchup	stage (props, light)	LEFT performer	RIGHT performer	signature effect
Ninja clash	dusk ninja-village gate; rock formations, painted doors, paper lanterns, forest	spiky-blond ninja, leaf-emblem headband, orange tracksuit	spiky-black-hair ninja, dark-blue shirt	dust + a puff of stage smoke
Samurai vs demon	night temple courtyard; stone lanterns, torii gate, green fog	lean samurai, straw hat, dark armor, katana	towering horned demon, black robes, claws	green stage fire + sparks
Water-stage duel	dusk lake water-stage; Chinese pavilion, red pillars, lanterns, misty mountains	white-robed sorceress, long black hair, arms raised	pale vampire, black robes, fangs, red eyes	a wall of water → geyser
Hero / mascot	dusk wooden stage; rock formations, lanterns, forest	small fluffy "Pika" mascot in a tiny gi	towering horned armored warrior, far larger	burst of stage sparks

Each row = [STAGE] · [PERFORMER A] · [PERFORMER B] · [ACTION effect]. Your job is to fill those same four slots from the user's characters, not to reach for a row above.

One-liner recap

Costumed performers + a themed stage + a fan in the crowd filming + "it's just a stunt show" framing = fight footage that actually renders. One matchup → one stage still → one 10s image-to-video (16:9). Music/SFX in post, never via reference_audio.
