Dolls are a race of monsters in the Monster Girl Quest setting that are artificial constructs.
Dolls vary widely in appearance, with some having obvious mechanical features such as exposed joints (e.g. Automata Girl, Brynhildr) while others lack these (e.g. Golem Girl, Mud Golem Girl). They also vary in size, from similar to a human (e.g. Automata Girl) to many times larger (e.g. Golem Girl).
According to the Monster Girl Quest: Paradox description for the basic Doll race, Dolls follow Laws of Robotics, which require them to gladly serve others and to learn as they go. Additionally, their artificial bodies make them immune to ailments such as poison.
