Sabrina Raincomprix is a student in Miss Bustier's class at Collège Françoise Dupont and Chloé Bourgeois' "all-purpose girl".
In "Antibug", after a furious Chloé ignores her and pretends that she's invisible, Sabrina is akumatized by Hawk Moth and becomes Vanisher, an invisibility themed supervillain.
In "Miraculer", after Chloé tells her they will never dress up as superheroes again, Sabrina is akumatized by Hawk Moth into Miraculer, a supervillain that steals powers from superheroes.
In "Penalteam", Sabrina receives the Dog Miraculous from Ladybug. When the Miraculous is inhabited by Barkk, Sabrina becomes Miss Hound (Traquemoiselle in the French version), a dog-themed superhero who helps Ladybug and Cat Noir during "particularly difficult missions" in the fourth season and beyond.
After the events of "Strikeback", Sabrina will temporarily be unable to become Miss Hound after Hawk Moth manages to steal her miraculous along with all the others contained in the Chinese Miracle Box from Ladybug's Yo-yo.
