Dalk

Dalk (ダルク, Daruku) is the Doll of Gō Koga. Dalk takes the form of an adult Human-sized creature composed entirely of metal. Her face is light gray in coloration with completely green eyes, thin red eyebrows that are constantly inwardly diagonal, a small nose, and a dark gray mouth with an equally dark tongue. The rest of her body is dark gray in coloration, with her head featuring seven triangular spikes arching outward along the edges with vertical symmetry. Her upper torso has two large breast-shaped mounds of metal on the front, multiple small bumps on the back, and a thick raised double-pointed line wrapping diagonally around the back to point downward at the front, while each of her shoulders terminates in a large metal sphere attached to the joint; each of these spheres has two arms comprised of a bone-shaped upper arm and a sharp, serrated forearm with two blades, both attached to each other and the shoulder joint by smaller metal spheres. Below the waist, Dalk has a spider-like body composed of three different sections attached to each other: the first directly below her hips is completely spherical with two legs featuring sharp tips connected to the bone-shaped thighs by small joints, the second spherical segment connected to the first has two more identical legs and an additional bean-shaped plate of metal on the underside where the legs originate from, and the third segment is more conical in shape with four spheres half-embedded in the metal at 90-degree angles. Prior to Koga and herself being empowered by Bitto serum, Dalk took on a smaller, more humanoid form where her eyes were narrow instead of circular and her head was devoid of spikes, instead being completely smooth with a small spherical protrusion on either side of her face, resembling hair.
