Heroism Wiki

The Cat Miraculous is a magical jewel wielded by the superhero Cat Noir and an item featured in the animated series Miraculous: Tales of Ladybug & Cat Noir.


The Cat Miraculous is connected to the kwami Plagg and has been worn by many for years. Whenever Plagg goes inside, it transforms the holder into a cat-themed superhero. The Cat Miraculous has incredible powers of speed, endurance, and strength. Its special weapon is an unbreakable staff, which can be utilized as both a weapon and a communicator. Its special superpower is called the Cataclysm, giving the user the ability to damage or destroy an object, like structures or metal bars.

This jewel is currently owned by Adrien Agreste, a student in Miss Bustier's class at Collège Françoise Dupont in Paris, France. But in the past it was owned by an ancient Chinese Black Cat.


The ring has a thick band with a circle surface surrounded by a lining with four pointed diamond shapes on each diagonal side. In charged mode, it is black and a glowing green cat paw print appears in the circle. If a minor uses the miraculous, once they've used Cataclysm, the ring starts running out of power, each toe of the paw print will disappear one at a time as an indication of how much power and time he has left until he turns back. Until the ring turns completely black, which is how the activated mode of the miraculous looks.

In its camouflage mode, the ring changes color depending on whose possession it's in:

  • In the possession of Adrien Agreste, it is silver and the circle is blank.
  • When worn by Marinette Dupain-Cheng, the ring is rose gold/grayish amaranth and the circle is blank.

Powers and Abilities

The Cat Miraculous grants its wielder incredible powers of superhuman speed, endurance, night vision, and strength. Its special weapon is a staff, which can be utilized as both a weapon and a communicator to other heroes. Its special superpower is Cataclysm, which gives the user the ability to damage or destroy an object, such as structures, akumas' hiding places, or metal bars. It also gives the power of night vision to its user. As long as the superpower isn't used, the wielder can remain transformed indefinitely. However, as soon as the superpower is used, the wielder's Miraculous weakens and the transformation usually wears off in about five minutes.

If the Ladybug Miraculous and the Cat Miraculous are used together while also using a special invocation, the holder will achieve ultimate power. The person wielding them can make a wish that can alter reality. However, because the universe must maintain balance, every action has a reaction; for instance, a wish to become human would result in someone losing their humanity.
