The Mouse Miraculous is a pendant necklace that is circular and dark gray with lighter gray markings and five pink rats in a circle on the front of it.
When in camouflage mode, it appears as a bronze Chinese coin when worn by Marinette, and a golden pendant when worn by Chloé.
The Mouse Miraculous provides its wielder with enhanced characteristics such as strength, speed, stamina, endurance and agility. The Mouse Miraculous' tool is a Jump Rope, with each end of the rope appearing to have handles attached, which are black with large, silver-colored spheres.
Its special superpower, Multitude, allows the user to shrink down and create numerous clones of themselves for an unknown amount of time.
A French teenage girl. After Wang Fu relinquishes his duty as guardian and lost his memory in the process, Marinette becomes the new guardian of the Miraculouses. She is currently storing the Mouse Miraculous in the Miracle Box when not in use.
