In the future, when the situation calls for it, the pendant necklace will temporarily be lent to Mylène Haprèle, who will use it to transform into a currently unnamed mouse heroine.
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.
