Max Kanté[6] is a supporting character of Miraculous: Tales of Ladybug & Cat Noir. He is a student at the Collège Françoise Dupont and a former student of Miss Bustier's class, before she became mayor of Paris.
In "Gamer", when he lost his place in the school video game tournament because of Marinette Dupain-Cheng, he was akumatized by Hawk Moth and became Gamer, a video game-themed supervillain who controlled a huge fighting robot.
In "Startrain", in order to save his mother, who was akumatized into the titular villain, and his friends, Max received the Horse Miraculous from Ladybug. When the Miraculous is inhabited by Kaalki, Max becomes Pegasus, a horse-themed superhero with the power of Migration who helps Ladybug and Cat Noir during "particularly difficult missions" in the third season and beyond.
In "Gamer 2.0", after being turned down by everybody to play his creative video game, Max was reakumatized into Gamer, with the new title Gamer 2.0, getting a new ability to create a video game in real life.
After the events of "Strikeback", Max was temporarily unable to become Pegasus after Monarch managed to steal the Horse Miraculous along with all the others contained in the Chinese Miracle Box from Ladybug's yo-yo.
In "Re-creation", after Ladybug recovered the stolen Miraculous and reforged them following Monarch's defeat, Max was given back the Horse Miraculous permanently and reunited with Kaalki.
In "Revelator", it's shown that, after getting his Miraculous back, Max, along with the other secondary heroes of Ladybug's team, was trained to unlock his adult powers, no longer detransforming after using his power.
