Thunderbird Boss in Stormlit Game World

A colossal thunderbird, a mythic avian with iridescent cobalt and gold feathers crackling with electricity, perches atop a jagged cliff above a rain-soaked canyon. In a high-fantasy video game world, the scene feels cinematic and action-ready: dark storm clouds churn, lightning forks illuminate the battlefield, wind-swept rain creates spray, and ancient ruined temple pillars glow with faint runes along the wings. The thunderbird's eyes glow amber; wings ripple as electric energy arcs along every feather, leaving bright trails of sparks. The art style is digital with AAA-game quality, featuring crisp polygonal shading, photorealistic feather detail, PBR materials, and dynamic lighting. Lighting is dramatic with volumetric fog, bloom, and subtle depth-of-field. The composition shows the thunderbird in a powerful pose—an imminent dive or guarding stance—dominating the frame, with a stormy sky and a distant fortified fortress in the background. Color palette blends midnight blues, electric cyan, violet, and gold highlights. This prompt yields a bold, epic boss encounter concept art suitable for a fantasy RPG game's design documents or in-game cinematic.
