THE LEVIATHAN PROTOCOL — two-reference workflow

=== STEP 1 · ESTABLISHING FRAME ===
Model: Nano Banana Pro (image) · two reference images: your face + the creature design sheet

Photorealistic cinematic establishing frame, 16:9. A lone tactical airborne hero (use reference 1 for the exact face/identity) in a black tactical jacket, three-quarter rear, hovering low over a violent storm ocean. Ahead rises a colossal water-and-mist elemental (use reference 2 for the design): a ~300m translucent ocean-water body draped in a flowing mist shroud, glowing electric-blue veins, a bright blue vortex core in its chest, glowing eyes, whirlpool lower body, water cascading off its arms. Dark overcast storm sky, heavy mist, crashing waves. Steel blue, charcoal gray, deep ocean black, cold white highlights. Single hero, single colossus, no text — a water spirit fully formed of water and mist, no bare skin.

=== STEP 2 · MOTION (Seedance 2 · image-to-video) ===
Start image: the establishing frame from Step 1 · 16:9 · 720p · 15s · genre: epic

One continuous storm-ocean battle.
THE APPROACH — the hero accelerates low over the waves toward the colossus; hold a beat on its glowing face.
THE THREAT — the colossus swings a massive water fist; the hero barely twists aside as it smashes the ocean beside him.
THE CHARGE — the hero hovers back and gathers a bright blue energy orb between his hands.
THE STRIKE — he fires a concentrated energy beam across the gap into the colossus's chest core; it detonates on the core and the chest ruptures. The hero stays at range — he never touches or passes through the body.
THE AFTERMATH — the colossus disperses into water; pull back to an aerial wide as ripple waves spread and the lone hero hovers above the battlefield.

Preserve the hero's exact identity and the elemental's design throughout. Steel blue, charcoal, deep ocean black, cold white highlights, bright blue energy.
