Alix Kubdel/History

Alix Kubdel is a teenage girl in Miss Bustier's class.

Season 1
In "Ladybug & Cat Noir (Origins - Part 1)", Alix is one of the students at Collège Françoise Dupont joining Miss Bustier's class. After class is over, she goes to the field for gym class. She is later seen leaving the field just before Stoneheart arrives.

In "Stoneheart (Origins - Part 2)", Alix is one of the many people who crowd Ivan after his previous akumatization, asking him if he seriously doesn't remember anything. During attendance, she is as surprised as everyone else when Ivan is reakumatized. Later, Alix, along with her classmates and other Parisian citizens, hears Hawk Moth's demand that Ladybug and Cat Noir surrender their Miraculouses. She is horrified, but when Ladybug refuses and vows to protect the Parisians, Alix cheers. The next day, she is amused when Marinette stands up to Chloé.

In "The Bubbler", Alix is one of the many people Bubbler forces to attend a surprise birthday party for Adrien. Though she dances at the party, she is shown to be quite miserable. She cheers when Ladybug and Cat Noir show up to stop Bubbler, but she gets bubbled by him a a result, though she is later freed after his defeat.

In "Timebreaker", Alix celebrates her 15th birthday with her father at Le Grand Paris hotel's restaurant. When Mr. Kubdel asks Alix why she didn't dress up, Alix merely points out that she did take off her cap. Mr. Kubdel then presents her with a silver pocket watch as a gift. At first, Alix is uninterested by it, but after her father shows her that it produces a hologram when opened, she takes a liking to it. She then receives a message reminding her about the bet between her and Kim happening at Trocadéro. Though she doesn't want to ditch her father, Mr. Kubdel allows her to go, but not before reminding her to take care of the watch. At Trocadéro, after Max explains the rules of the bet, Alix takes out her watch and asks Alya to hold it while she races Kim. The watch ends up being passed along from classmate to classmate until Chloé drops it and Alix accidentally skates over it. Horrified, Alix angrily blames her entire class. Marinette suggests that maybe she get the watch fixed, but Alix tells her that the watch was unfixable as it was one-of-a-kind. She is then akumatized into Timebreaker and begins touching people in order to steal their energy so that she can travel back in time and save her watch. After stealing Cat Noir's energy, Timebreaker has enough power to go back in time and therefore does so, but she fails in stopping the watch from being broken. The other Alix blames Ladybug for incident and is also akumatized into Timebreaker. Then the other Timebreaker offers her her help. The two Timebreakers battle Cat Noir and two Ladybugs but are defeated in the end. Ladybug then gives Alix her watch back. Alix thanks her for fixing it and realizes that she never should have let anyone watch over it for her, promising to be more careful.

In "Pixelator", during Miss Bustier's class trip to Le Grand Paris hotel, Alix is shown having a pillow fight with Ivan until Miss Bustier reminds the two that what they are doing is worth a huge portion of their grade.

In "Gamer", Alix watches as Max and Adrien compete to be finalists in a video game competition. She then watches as Max and Marinette compete and is surprised when Marinette defeats Max easily. She's shown to feel bad for him losing his spot, though when the actual competition comes around, she cheers as Max and Marinette enter the arena.

In "Reflekta", Alix is put in the front row of the class photo. When Juleka winds up akumatized, Alix is one of the many people affected by Reflekta. However, she is returned to normal after Reflekta's defeat and goes to take multiple class photos with her friends at the park.
