Cyberpunk Portable Device

Against a neutral gray background, a slim humanoid mecha with a matte black body stands facing forward with arms slightly spread. A cyan blue visor gleams sharply on the white face plate, while pointed blade antennas extend from both sides of the head like fighter jet wings, completing the aggressive head design. Neon yellow and cyan blue energy lines flow like circuit patterns along each joint and seam of the matte black armor, with cyan blue energy cells in the center chest and knees emitting intense light. Large blade-type wing units extend in four directions from the back, creating a silhouette like spread wings, with yellow energy points glowing at the wing tips. Shield-type side armor mounted on both hips demonstrates the balance between defense and mobility, while the pointed design of the feet suggests high-speed maneuverability. This cyberpunk concept art illustration captures the sharp and futuristic presence of a next-generation combat humanoid mecha through the sophisticated color scheme of matte black and neon cyan.
