This angry male character face looking upwards exposing its neck is a monochromatic, black-and-white drawing by Tsutomu Nihei in a comic book style. The subject is a humanoid figure with a skeletal appearance, resembling a robot or alien. The figure's face is prominently displayed, showing a large, gaping mouth filled with sharp teeth, giving it a menacing or threatening expression. The head is smooth, with no visible eyes, and the skin texture is suggested through hatching lines and shading, indicating a metallic or bone-like surface. The figure's shoulders and upper torso are also visible, featuring large, bulky, and segmented armor-like structures, with intricate detailing that suggests a mechanical or cybernetic design. The background is completely black, making the figure stand out starkly against the stark contrast. The drawing style uses bold, thick lines for the outlines and finer, cross-hatched lines for shading and texture, typical of comic book art. The overall effect is one of foreboding and otherworldly presence, with the character's skeletal structure and lack of facial features adding to its eerie and unsettling appearance.
