a stunning, highly detailed illustration of a muscular, humanoid figure with an ethereal, luminescent aura, radiating vibrant, crimson energy that crackles through their skin, as if their body is a vessel for an explosive, fiery power, their clenched fists glowing with an intense, inner light, set against a dark, foreboding sky with clouds that seem to swirl in turmoil, reflecting the figure's intense, brooding expression, with eyebrows furrowed, eyes blazing like hot coals, and a tight, determined jawline, every muscle tensed, as if on the verge of unleashing a maelstrom of energy, in an ultra-high resolution, best-quality image with razor-sharp lines, intricate textures, and a rich, dynamic color palette.
