As Timebreaker, her rage increases to the desire of revenge without regret against her classmates. She is very determined to fix her watch, and she doesn't care about anyone that she takes energy from to do so, even taking advantage of Rose Lavillant's kindness. While wanting to succeed, Timebreaker is willing to retreat if it means a better chance. Despite this, her overconfidence in her abilities is her downfall when she assumes the present and future Ladybugs aren't clever enough to stop her.
- In the French version, Alix's villain name is Chronogirl.
- She is the first villain in the show to kill a hero, Cat Noir, by touching him while he is protecting Ladybug — although Ladybug goes back in time and prevents this outcome from happening again.
- This also may count as the first known death of a kwami and a Miraculous, as Plagg is in the ring for Adrien to be Cat Noir.
- Timebreaker reappears in the two-part special event "Heroes' Day".
- Timebreaker appears another time in "Gamer 2.0" for Gamer's powers.
- A statue of Timebreaker appears in the Musée Grévin in "The Puppeteer 2".
- Her Timebreaker suit makes the same noise as the Prototype Omnitrix, which is a broken watch like the Rabbit Miraculous, which is also capable of holograms, transformations, and, through transforming, time travel.
