Miraculous are ancient magical jewels that grant their holders extraordinary powers when inhabited by small, god-like creatures known as kwamis. Each Miraculous is tied to a specific concept, such as creation or destruction, and provides a unique transformation, weapon, and special ability. To activate a Miraculous, the holder must wear the jewel and speak a specific transformation phrase associated with its kwami. For example, in Miraculous: Tales of Ladybug & Cat Noir, Marinette Dupain-Cheng says “Tikki, spots on!” to transform into Ladybug, while Adrien Agreste says “Plagg, claws out!” to become Cat Noir. Upon activation, the kwami merges with the holder, surrounding them in magical energy that forms their superhero suit, mask, and weapon in a rapid transformation sequence. Once transformed, the holder gains enhanced abilities along with a special power unique to their Miraculous. However, using this special ability typically triggers a time limit for inexperienced users, requiring them to detransform once the energy is depleted. To return to their normal form, the holder speaks a de-transformation phrase, releasing the kwami from the Miraculous. Miraculouses are stored and protected within the Miracle Box, overseen by a Guardian who ensures they are used responsibly. Because of their immense power, they are often sought after by villains, making their protection essential to maintaining balance between good and evil.
