Alix Kubdel (aka Bunnyx) is a student in Miss Bustier's class at Collège Françoise Dupont. In "Timebreaker", after Alix's birthday gift, a special pocket watch, is accidentally destroyed, she is akumatized by Hawk Moth into Timebreaker, a time traveling supervillain and love interest of Lê Chiến Kim/King Monkey.
In "Timetagger", it's revealed that Alix will receive the Rabbit Miraculous in the future. When the Miraculous is inhabited by Fluff she becomes Bunnyx, a rabbit-themed superhero.
- In the first issue of Miraculous Adventures, Alix is on a lacrosse team with Adrien, Ivan and Kim.
- Her voice actress, Kira Buckland, is best known for voicing Izumo Kamiki from the Blue Exorcist series, Jibanyan from Yo-kai Watch Season 3, Umi Sonoda from Love Live!, Hiyoko Saionji and Kirumi Tojo from the Danganronpa video game/anime series, 2B from NieR:Automata, Julis Riessfeld from The Asterisk War and Petunia Rhubarb & Laura Carrot from The VeggieTales Show.
- She turns 15 in the episode "Timebreaker".
- As implied in "Reverser", Alix goes to the art class to express herself through street art.
- Alix's family are of Amazigh origin.
- Alix may be a play on Alice from Alice in Wonderland.
- 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".
- In the French version, Alix's villain name is Chronogirl.
- Alix's past self was transformed before she accepted Hawk Moth's deal.
- Bunnyx, Alix's future superhero identity, has a watch, also making a reference to the White Rabbit from Alice in Wonderland.
- Because of the Rabbit Miraculous' power, Alix will be the only known member of French Miraculous superhero team to know the identities of Ladybug and Cat Noir.
- So far she's the only superhero whose power shares similarities to her power from when she was akumatized, with both Timebreaker and Bunnyx having the power to travel through time.
- As of "Timetagger", Alix is the only member of the team who didn't get her Miraculous in the current timeline.
- Similar to Cat Noir and Rena Rouge, Bunnix's ears are fake. It's been seen that they respond to her mood as they went down due to her exhaustion and sadness of her inability to beat Timetagger in the same episode.
