Chloé Bourgeois is a character in Miraculous Ladybug. She is Marinette's rival and a student in Miss Bustier's class at Collège Françoise Dupont. Her father, André Bourgeois, is the mayor of Paris. In "Antibug", after Ladybug ignores her suggestions on how to beat Vanisher and calls her a liar, she is infected with an akuma by Hawk Moth and becomes Antibug, a supervillain copy of Ladybug.
Chloé stands at a medium height, with honey blond hair pulled back into a ponytail and blue eyes. She wears makeup, including blue eye-shadow, nude lipstick, and light peach-colored blush. For accessories, she has a dark gold chain necklace with a dark gold sphere charm, and she has white rimmed sunglasses on her head. Additionally, she wears a yellow long-sleeved jacket over a white shirt with black stripes around the waist. The rest of her outfit includes white jean capris with a belt that has diamond-shaped studs and white dress shoes with black lining and soles.
As Antibug, she wears a costume similar to Ladybug's, but with inverted colors.
Chloé is spoiled, pretentious, and superficial. She does everything she can to crush and humiliate the other students, especially Marinette. Her father being Mayor of Paris and spoiling her all her life, she believes she is the most important person in the world and everyone adores her. She thinks highly of herself and lowly of others, thinking she deserves everything and taking pride in her popular, rich lifestyle. If there is something that she wants, like Adrien's attention or revenge against Marinette, she will do anything, including underhanded actions, to succeed. She steals Marinette's derby hat design in order to humiliate her and impress Adrien and Gabriel Agreste in "Mr. Pigeon", and she threatens Mr. Damocles to punish Alya by calling her father in "Lady Wifi". Her sour attitude comes across openly to whatever and whoever she despises, but she will sometimes pretend to be innocent and emotional to manipulate others, from her father to Adrien. She rarely treats any of her peers respectfully, and she is even bossy and overbearing to her best friend, Sabrina.
While being callous and careless to anyone but herself, Chloé is easily scared at danger, often by akumatized villains. Having helped caused some people to be akumatized, Chloé, to her horror and confusion, finds herself their victim for revenge. Despite some of the villains calling her out for her nasty behavior, Chloé disagrees with them, believing she is good. She remains awful most of the time, but occasionally, she shows a bit more kindness, sometimes expressing happiness about Ladybug saving her or expressing it towards Sabrina. She also listens to advice at rare moments, like following Ladybug's suggestion to reconcile with Sabrina in "Antibug".
