Create an image of a cybernetic humanoid assassin in a dark, dystopian setting. The figure should have a metallic skull with intricate mechanical details and a partially human-like appearance. It should be dressed in a long, black leather coat adorned with various cybernetic enhancements and accessories. The assassin is holding a futuristic pistol, aiming it with a cold, calculating expression. The background should be dimly lit, emphasizing the assassin's menacing presence and highlighting the metallic and leather textures. The overall mood should be intense and foreboding, capturing the essence of a high-tech, dystopian world.
