A medium shot from a low-angle perspective captures a colossal black dragon dominating the frame, its massive body coiled with immense power as it spreads its enormous wings wide. The dragon is depicted mid-roar, its mouth open wide to reveal sharp teeth, with piercing golden eyes that glow with intensity. Its scales are a deep, matte black with a rough, obsidian-like texture, and its powerful muscles ripple beneath its skin. Violent arcs of purple lightning crackle and surge across its entire body, emanating from its wings and claws, illuminating the scene with electric flashes. The background is a dark, storm-filled sky with swirling charcoal clouds and distant flashes of purple light, emphasizing the dragon's immense scale and presence. The atmosphere is epic and menacing, characterized by a high-contrast color palette of deep blacks and vibrant purples, with cinematic lighting that highlights the metallic sheen of the scales and the electric energy of the thunder.
