Yo-yo

The yo-yo is Ladybug's weapon.

Stipid yoyoyoyoyoyo

Abilities
The yo-yo has many functions.
 * Ladybug uses it as a weapon, both offensively and defensively: when swung in a circle very quickly, it lights up pink and creates a shield able to deflect and withstand strong attacks, along with carving through big things that are thrown at it, like a bus in "Stormy Weather".
 * As a grappling hook.
 * It is believed to be unbreakable.
 * To purify and revert akumas back to normal butterflies.
 * To use Lucky Charm: when Ladybug throws the yo-yo in the air, it unleashes a pink energy that produces an object.
 * One side of the yo-yo can slide or open, revealing one or two screens. With this, Ladybug can use the yo-yo as a tracker, a map and as a communicator to contact Cat Noir or other phones.

Trivia

 * In concept art and test animation in the 2014 licensing video, the yo-yo appears to have more abilities, like being able to split in half to become a staff, generating a wing-like shield, and exploding like a bomb. If Ladybug will have any of these abilities in the show, or if these are done with the yo-yo or something else, has yet to be revealed.
 * In "Copycat", one side of the yo-yo has inverted colors (black with red spots), like when Ladybug is using it as a communicator. Thomas Astruc said that it was a mistake that couldn't be fixed.
 * In "Stoneheart (Origins - Part 2)", it is revealed that the yo-yo is capable of capturing more than one akuma.
 * Ladybug drops the yo-yo on Cat Noir's head three times during Season 1: in "The Bubbler", "Stormy Weather", and "Ladybug & Cat Noir (Origins - Part 1)".
