As Monster High is about teenagers, obviously, it has to reserve a spot for celebrities to idolize. To fill that spot, several celebrity backgrounders occasionally show up.
Justin Biter[]
First mentioned in "New Ghoul @ School", Justin Biter is a vampire and pop star. He owes the resurrection of his career to Frankie Stein's father. Because of this, Frankie was able to get him to give a concert at Monster High to apologize to Cleo de Nile, a big Justin Biter fan. Later, Frankie got herself two tickets to a Justin Biter concert in "HooDoo You Like?". She also had tickets to see another of his concerts in "Best Ghoulfriend"; but she had eight that time, so she could take all of her friends.
The Facebook entry of January 20, 2011 mentions that Draculaura and Clawd Wolf went on a date to a Justin Biter concert.
- Justin Biter is based on Justin Bieber.
Jaundice Brothers[]
The Jaundice Brothers one appearance happened in "Jaundice Brothers". Frankie Stein and her friends entered a contest of radio KBLOOD to get the Jaundice Brothers to play at Monster High's Homecoming Dance. Naturally, they won. The Jaundice Brothers were later mentioned by Draculaura in "New Ghoul @ School" as her former idols.
- The Jaundice Brothers are based on the Jonas Brothers.
Unnamed DJ/DJ Death Breath[]
In the webisode "Party Planners", Frankie Stein's and Draculaura's friends threw the two a birthday party for which they hired a four-armed DJ. In "New Ghoul @ School", he was confirmed to be a celebrity, though his name remained unknown.
Meanwhile, the Facebook entries of August 2, 2011 and March 15, 2011 make mention of a famous DJ, DJ Death Breath, who occasionally pops up in the neighbourhood and who is Holt Hyde's music idol. It is possible he and the four-armed DJ are the same, but such connection is not confirmed.
Football stars[]
The Facebook entry of July 31, 2011 was a message from Clawd Wolf, who was stoked to be at the Football Hall of Fame and to meet some of his heroes: Scary Madsaw, Grim Brown, and Howlie Long!
- Scary Madsaw, Grim Brown and Howlie Long are based on Terry Bradshaw, Jim Brown and Howie Long.
Paulo Dragonfire[]
The Gory Gazette entry of June 18, 2012 mentioned Paulo Dragonfire as a famous swimming pool designer commissioned to build a pool for Lagoona Blue's swim team party.
"Dragonfire is known for his outlandish landscaping and private swim park architecture which often includes Lazy Lizard Rivers, Surf’s Up Wave Parks and monstrously wicked water slides. "
- Paulo Dragonfire may be based on Paolo "Paul" Benedetti.
Kind Campaign founders[]
For the webisode "Kind: The Shockumentary", Kind Campaign founders Lauren Parsekian and Molly Thompson were monsterfied into water monsters, the blue-haired one being Lauren and the cyan-haired one being Molly. No in-universe names have been provided for these two.
Lauren and Molly visited Monster High on a request from Ghoulia Yelps, who was displeased with the way her female friends were treating each other. The duo got everyone together in the clawatorium and had them enter the kind booth to face the reality of their behaviour and their desire to do better. Once this procedure had restored peace at Monster High, Lauren and Molly left, another job well done.
Crescenda von Hammerstone[]
Crescenda von Hammerstone is a bull-horned Minotaur and opera singer. She has family in Gnarleston, Louisiana, and presumably grew up in the same or a nearby city. The Phantom of the Opera was her first vocal coach, and despite being a diva, Von Hammerstone is laid-back and casual in daily life. Operetta is a huge fan of hers, and won a meet & greet with Von Hammerstone in "Hickmayleeun".
Queen of Fangland[]
The Queen of Fangland is the ruler of Monster High's version of England. Clawdia Wolf mentions meeting her in one of her short stories.
Yuksques Cousteau[]
Yuksques Cousteau is a famous ocean explorer, whom Clawdia Wolf claims to have met in one of her short stories. His name is an obvious play on real life explorer Jacques Cousteau.
