Dark Subway Symbiote Anti-Hero

A hyper-realistic cinematic scene of a muscular anti-hero merged with a black alien symbiote inside a dirty subway train car. The character is mid-transformation, covered in a glossy black organic suit with sharp tendrils extending from his arms and shoulders. A large white skull emblem spreads across his chest, resembling a dark vigilante symbol. The symbiote appears alive, wrapping and stretching outward like liquid shadow. The setting is a grimy, dimly lit subway carriage with flickering fluorescent lights, scratched metal walls, broken trash and a crushed soda can on the floor. Rainy city lights blur through the window behind him. The atmosphere is dark, gritty, and tense. Ultra-detailed skin texture, wet symbiote reflections, dramatic cinematic lighting, high contrast shadows, photorealistic, shallow depth of field, 8k resolution, movie poster style, dynamic action pose, dark superhero horror aesthetic, volumetric lighting, film still quality.
