|“||Spoke too soon, Kim! Your ridiculous bets are over. I'm gonna leave you in the dust, meathead!||”|
Alix Kubdel 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, Hawk Moth infects her with an akuma and she becomes the time traveling supervillain Timebreaker.
Alix is short and lean with blue eyes and messy bob-cut pink hair that, on the right side, is partially tied into a small side ponytail.
Alix wears a black cap with a black old English S logo that is outlined in white on the front. She wears a black long-sleeved shirt underneath a dark gray tank top. Each sleeve has a lime green scale patterned fabric snake, starting from her shoulders and coiling around her arms until their heads stop at her wrists. She also wears black jean shorts with pink stitching and black lace at the cuffs, black 1/2 hose length socks with two pink horizontal stripes, and black high top shoes with pink lace, black and lime green checkered sides with a wavy orange line over it, and white soles.
When Alix is rollerblading, she wears a black helmet with a pink strap and the same S logo from her cap. She wears dark gray elbow pads and knee pads with pink stitching and blue plastic covering. Her rollerblades are dark blue with gray cuffs, a black line in front of the toes, pink liners, and pink and lime green stitching. They also have orange laces and lime green buckles. The wheels are gray with lime green centers and pink bolts attaching them to the black frame.
Timebreaker wears a black helmet with red spiked edges on the back and two green eye shields over each eye. She also wears a nearly black suit with lime green patches around her waist, around her lower hips and upper legs, and below her knees. Below her back of her wrists, there are glowing lime green ovals, and on her chest, there is a glowing red hourglass shape within a larger silver outline. Her rollerblades are black with two glowing white wheels on each one and a thin green line about the foot's ball and instep. A power bar is on the sides of the blades keeps tracks of her energy level, the lowest level being red and becoming greenish-blue at the top when it's full.
Alix is a tomboy. Tough, stubborn, and self-confident, she isn't afraid of challenges or saying what is on her mind. At the same time, she can be kind and grateful, like when her father gives her the family heirloom and when Ladybug fixes it after it breaks. She can become emotional and hold resentment toward others if someone goes wrong because of them, like with her watch. After the akuma is defeated, she realizes her own fault of not taking better care of the watch, and she tells Ladybug that she'll be more responsible with it.
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'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.
As a civilian
Alix is exceptionally fast and skilled at rollerblading.
Timebreaker becomes much faster at rollerblading. She also gets the power to absorb life energy from people by touching them with the palm of her hand. She is not above exploiting compassion in order to lure a target close enough to drain them, in this case, she called out to Rose for help when knocked down. Once their energy is stolen, the affected person becomes frozen and starts to fade from existence. The energy is stored inside her rollerblades, and the more Timebreaker has, the faster and stronger she gets. Timebreaker is also able to use her energy to go back in time; the number of minutes she's able to rewind depends on how many people she freezes and how much energy they give.
Alix often competes with Kim as he challenges her to several of his dares. His most recent dare involved a race around the school to see if he is faster than her rollerblades. During the rules of the dare as stated by Max that Kim would win Alix's rollerblades, but if Alix wins Kim would have to stop issuing dares to the delight of the school for the rest of the school year.Mr. Pigeon", in "Timebreaker" Ivan was part of the crowd cheering for her during the race and in "Pixelator" they have a pillow fight while on work experience at Le Grand Paris.
Alix's relationship with her brother is actually unknown. She doesn't speak about him to anyone.
Alix appears to have an amicable relationship with her father, choosing to spend time with him on her birthday over spending time with her friends, as seen in "Timebreaker".
