A realistic photograph of Hellboy, depicted from the waist up, facing slightly to the right with a determined, battle-hardened expression. His iconic right hand of doom is prominently featured, glowing with subtle, internal energy, while his left hand holds a smoking pistol. His large, filed-down horns are visible, and his trench coat is rendered with realistic fabric folds. The background is a clean white studio background. The overall aesthetic is hyperrealistic, with a focus on detailed textures and dramatic lighting.
