The Ninja Puppet, Sasori’s Hiruko, is a medium-sized, intricately designed puppet with a wooden and metallic construction, featuring a segmented, scorpion-like tail and a humanoid upper body. Its surface is a mix of smooth, polished wood and rough, battle-damaged metal plates, with a color scheme of dark reds and blacks, accented by glowing purple chakra lines. The puppet's design includes ornate engravings and embossed patterns, with a distinctive, menacing faceplate and articulated limbs for dynamic movement.
