Sea Colossus — You vs a Giant Ocean Titan
BACK2LIFE.APP TUTORIAL

Sea Colossus
You vs an Ocean Titan

Turn a single selfie into a flying superhero battling a skyscraper-sized water titan across a storm ocean — a full five-shot cinematic sequence generated from one structured Seedance 2.0 prompt and three reference images.

Tool: Seedance 2.0
Shots: 5-shot sequence
Difficulty: Advanced
Time: ~25 mins

What You'll Create

This is the most structured prompt format in the series — a full reference-locked, five-shot action sequence written like a mini screenplay. You supply three reference images: your superhero portrait (@Image1), a character board that locks your suit and proportions (@Image2), and a sea monster design board (@Image3). The prompt then locks both characters so they stay identical across all five shots — approach, engagement, charge, strike, and aftermath — while the model handles the ocean physics, storm atmosphere, and final vortex explosion.

Generate the superhero portrait and both boards from your selfie first

Create Your Three Reference Images

The reference lock only works if the images exist first

1

Start with a clear selfie or portrait — good light, face straight to camera. Use an image model (GPT Image 2, or the Back2Life AI Studio) to turn it into a full-body superhero portrait: dark tactical suit with glowing blue detailing works best against the storm ocean palette.

2

Generate a character board from that portrait — front, side and back views plus face close-ups on one sheet. This is @Image2 and it is what keeps your face and suit identical across all five shots.

3

Generate a sea monster design board — a massive humanoid water titan with a translucent ocean body, rotating vortex core, and a whirlpool lower body, shown at multiple angles with scale references. This is @Image3.

4

Keep all three images in 16:9 or square, high resolution, with clean uncluttered backgrounds.

💡

Pro tip: The character board matters more than the portrait. If the model ever loses your face mid-sequence, it is almost always because the board lacked a clear front-facing close-up.


The Three Reference Boards

The exact boards used for the example video — with the prompt that created each one

These are the actual reference images fed into Seedance for the example output on this page. Copy the prompt under each board, swap in your own selfie as the source, and generate your own set — they map to @Image1, @Image2 and @Image3 in the master prompt.

@Image1 — Superhero Portrait
Superhero portrait reference — full body hero in neon circuit suit
📋 Image Prompt — Superhero Portrait (@Image1)
Ultra-realistic full-body cinematic portrait, 9:16, of the man in the reference selfie as a superhero, standing facing camera in a powerful wide stance with clenched fists. Skin-tight black armoured suit made of cracked-scale textured panels, laced with glowing neon circuit lines in cyber cyan, neon purple and electric pink running along the arms, torso and legs. Glowing neon emblem on the chest: a minimal side-profile human head containing a play-button triangle with circuit traces descending below it, drawn in cyan-to-purple gradient neon. High armoured collar, dark tactical utility belt, armoured gloves and boots, long dark navy cape falling behind the shoulders to the floor. Wet reflective black studio floor, drifting blue smoke, dark moody backdrop lit with a cold blue rim light. Photorealistic skin, sharp facial likeness preserved from the reference, dramatic hero lighting, 8k detail.
@Image2 — Character Board
Character reference board — profile, turnaround, costume details, palette
📋 Image Prompt — Character Board (@Image2)
Professional character reference sheet, 16:9, dark UI design on a near-black background, for the superhero in the reference image. Layout: large full-body hero shot on the left standing on a wet reflective floor; CHARACTER PROFILE panel listing NAME: INSTINCT, ALIAS: THE CURRENT, ORIGIN: UNKNOWN, HEIGHT: 6'1" / 185 CM, WEIGHT: 197 LBS / 89 KG, BUILD: ATHLETIC / PEAK HUMAN, EYES: BROWN, HAIR: GRAY, AFFILIATION: INDEPENDENT, ROLE: PROTECTOR / ENFORCER, ALIGNMENT: NEUTRAL GOOD; a short BACKGROUND paragraph; a TURNAROUND section with front, side and back full-body views including the cape with a glowing circuit line down its centre; a FACE CLOSE-UP panel; a COSTUME DETAILS grid with labelled crops of the energy core chest logo, shoulder armour, utility belt, energy veins, armoured gloves and armoured boots; a COLOR PALETTE row of hex swatches #00FFFF cyber cyan, #7A00FF neon purple, #FF00D4 electric pink, #0F172A deep navy, #E6F1FF soft white; a MATERIALS & TEXTURES strip (cracked scale armour, energy vein glow, micro mesh, gunmetal hardware, satin cape weave); a POWER VISUALIZATION panel of the hero crackling with blue-purple lightning; and a SUIT SCHEMATIC line drawing front and back. Same face, suit and emblem in every panel, clean sans-serif labels, studio quality.
@Image3 — Sea Colossus Design Board
Sea Colossus design board — turnaround, close-ups, poses, scale
📋 Image Prompt — Sea Colossus Board (@Image3)
Creature design reference sheet, tall vertical layout on a clean white background, titled SEA COLOSSUS — THE ABYSSAL ENTITY. Subject: a massive humanoid titan made of living ocean water — dark abyssal blue-purple translucent body streaked with glowing cyan and purple energy veins, blazing white-blue eyes, a bright lightning energy core in the chest, and a lower body that dissolves into a churning whirlpool of waves, spray and dripping water. Layout: large hero render top-left with a short description block and a SCALE REFERENCE note (height approx 300–400 meters, 3x the Empire State Building, with a 60–100 meter navy ship shown for scale); a 3D TURNAROUND row with labelled front, side and back views; a DETAILED CLOSE-UPS grid of head & face, energy core & veins, skin & muscle texture, and arm & hand detail; an IN ACTION / POSE EXPLORATION row of four poses including one gripping a warship; a BACK SURFACE DETAIL panel; a SILHOUETTE SCALE diagram comparing the titan against the Empire State Building and a human ship; and a COLOR PALETTE column with swatches #0A0E17 deep abyss, #0E2240 ocean depths, #00E5FF energy blue, #E8F6FF foam white, #4A5560 steel grey. Identical creature in every panel, clean editorial layout, concept-art studio quality.

Paste The Prompt & Generate

Copy it exactly — then customise once you've seen a clean run

1

Upload your three reference images in order — portrait, character board, monster board — so they map to @Image1, @Image2 and @Image3.

2

Copy the full structured prompt below and paste it in. Yes, all of it — the negative prompt block at the end is doing a lot of the heavy lifting.

3

Generate. If a shot drifts (face changes, monster mutates), regenerate — the reference lock keeps most runs consistent but Seedance still varies between seeds.

This YAML-style structure is a template. Swap the sea_monster block for a lava titan, sand colossus or storm giant, rewrite the five shots, and keep the reference_lock and negative_prompt sections untouched.
