Quilt is a character and body in Kaiba.
Quilt assists Patch in his factory. She helps him gaurd the "secret" of his work (see: Patch's history), and brings him to the lab to recharge him when he exhausts his energy supply. Quilt possesses Patch's eyes, and everything she sees is simultaneously visable to Patch.
Quilt is a small patchwork dog made of recycled dog bodies. Her fur is a combination of muted greens, violets and greys, and she has a red windup gear in place of a tail.
Patch sewed together parts of dog bodies abandoned by their owners to create Quilt. Shortly afterwards, he removed his eyes and gave them to Quilt.
