Operetta is the 16-year-old daughter on the Phantom with the Opera. She was developed in France, but raised in New Orleans, Louisiana where her father haunted a river-boat. For this reason, she speaks which has a thick Southern drawl. Her family gone after Monster High within work to correct an old opera theater that may be within the school's catacombs. Her diary is exclusive in that it truly is written as a letter to her guitar teacher and friend, Fynn.
Operetta has red hair, wears rockabilly-styled clothing, as well as a music note mask over her left eye. She's a talented musician like her father, but her voice is simply safe to be controlled by with a recording. She's got a recording studio underneath the catacombs. Operetta was mentioned in Holt's diary where the two happen to start a date. Operetta is mentioned again when Spectra spreads a rumor that Deuce is cheating on Cleo with Operetta; in fact, Operetta was merely assisting Deuce with writing a song for Cleo.Operetta makes her first webisode appearance in "Hiss-teria". Her pet is a spider named Memphis "Daddy-O" Longlegs.
