Miraculeur

After defeating an unseen villain called "Destroyer" alongside Rena Rouge and Carapace, Cat Noir tells Ladybug that she has to tell Chloé that her time as Queen Bee has passed since everyone knows about her being the superheroine, including Hawk Moth. Meanwhile, Hawk Moth wants Chloé to lose her trust in Ladybug to make her join him and decides that Lila can help. After Gabriel told her that Chloé is Adrien's childhood friend, Lila lies to Chloé that she has to do a special dance, so Ladybug can come and recruit her. When Ladybug is about to tell Chloé the bad news, she is distracted by a sentimonster created by Mayura. After Ladybug doesn't show up despite the "dance" Lila told her, Chloé, now aware that Lila lied to her, gets so infuriated that she is vulnerable to akumatization and even refuses to dress up as superheroes with Sabrina, hurting her friend. Hawk Moth sends the akuma to Chloé, but she resists the akumatization and the akuma goes to Sabrina who becomes "Miraculer", a villain capable of stealing the heroes' powers. After Ladybug and Cat Noir defeat the sentimonster, Miraculer steals their powers, forcing them to get help from their allies, including Chloé. When Cat Noir is about to give Chloé the Bee Miraculous, it is stolen by Mayura who the heroes meet for first time. After retrieving the Miraculous, Queen Bee goes after Mayura, but she escapes. After defeating Miraculer, Ladybug finally tells Chloé that she can't be Queen Bee anymore for the safety of hers and her loved ones. However, Chloé begins to slowly lose faith in Ladybug. Despite the failure, Hawk Moth is still determined to make Chloé join him.
