Cleo de Nile in "Here Comes Treble"

Cleo de Nile is a 2010-introduced and all-around character. She is a mummy and a student at Monster High. As royalty, Cleo is unsurprisingly the Queen of the student body, though few know her confidence is not as solid as she makes it seem to be. Cleo has difficult relationships with both her father, Ramses, who demands the best of and for her, and her older sister, Nefera, who cannot handle Cleo having any successes over her and as such regularly works to sabotage Cleo's efforts and undermine her self-esteem. Had it not been for the support of her friends from the Fear Squad, the loyalty of her BFF Ghoulia, and the comfort of her boyfriend Deuce's embrace, Cleo's crown would have been crushed a long time ago. Cleo is aware she is lucky to have found people around her that allow her to flourish and while not always the most tactful, she is very protective of her crew. Cleo and her family were once normies but Cleo's family went under a conspirancy led by her father's closest advisers, and so her father, her sister Nefera and her had to flee and be mummified in a dark room, with magical bandages. She stayed asleep for 1300 in the room.


Mummy Girl

In the music video for the Monster High Fright Song, while Cleo de Nile herself does appear in animation, she is also cast with several other character mummy analogues who received creative interpretation by the video crew. The mummy girl is played by Megan Mackenzi.

In the English version of the cartoon, Cleo's voice is provided by Salli Saffioti, who also happens to provide the voice for Clawdeen Wolf, in "Scaris: City of Frights" their voice was provided by Salli Saffioti Under The Alias Celeste Henderson.

In the Latin American version of the cartoon, Cleo's voice is provided by Rocío Bermúdez in the first and second volume, but since the third volume her voice is provided by Valentina Souza.

She was portrayed by Megan Nicole in the YouTube video of the Monster High special song "Digital Monsters, We are proud".



Cleo is extremely royal, so she expects everyone to treat her like it. Usually, her attitude is selfish, spoiled, and arrogant; she can't be entirely blamed for her behavior, because it's shown that she was raised to be like this. She is extremely competitive with other ghouls, especially Toralei Stripe. But deep down, Cleo's a very caring, kind, and thoughtful ghoul who cares about her friends.

Although Cleo has been known to take advantage of her friendship with Ghoulia Yelps by using her as a personal assistant or cheating off of her, she's very kind to her, and has helped her to overcome her shyness, showing that she really does care about Ghoulia and the friendship they share.

She can work well with the others if they share a common goal, like trying to avoid the gym teacher or helping Draculaura find her "perfect guy", in which case she becomes the de facto leader of the ghouls. She's a highly effective organizer and a leader.

In the first half of the Volume 1 webisodes, Cleo was the main antagonist and was archrivals with Clawdeen Wolf, but she eventually becomes much nicer to the ghouls. At the start of Volume 2, she's finally confronted with her own uncompromising, overbearing nature when all the fearleaders except Frankie Stein quit.


Cleo de Nile is in the possession of black hair, which is commonly enhanced with golden highlights, although she also picks blue, teal, and/or purple as additional colors. She favors her hair to be long and hang loose, but she isn't hesitant to switch it up with a shoulder-length haircut. She has tan skin and blue eyes, always surrounded by thick black winged eyeliner, and wears a gem on her right cheek that is blue in most of her ensembles. While Cleo can get creative with her look, there is one fashion rule she can't break: she always has to have at least one piece of burial wrapping on her, lest she disappears into dust. Cleo's Facebook profile Cleo de Nile's Gloom and Bloom diary Fortunately for her, she is allowed to apply the burial wrapping in whatever way suits her. Sometimes, she wears an entire jumpsuit with limb warmers made of the material. At other times, the burial wrappings are worked into a simple waist wrap easily forgotten among the rest of the look. Cleo's standard colors of choice to dress in are shades of yellow, including gold, which is her favorite color, and anything in the range blue-to-teal. She has also experimented with purple and red, but those are limited to specific periods. While not dress-shy, Cleo prefers to step into a pair of pants, usually as part of the aforementioned jumpsuit. As part of an Ancient Egyptian Royal Family, Cleo commonly works large gems into her look, as well as scarabs, lotusses, snakes, and triangles (pyramids).



Cleo lives with her father, and older sister, Nefera de Nile.[1] Her dad's name is Ramses de Nile, and he's an antiques dealer. Cleo and Nefera's mother is mentioned in her Gloom and Bloom Diary It is unknown what happened to her but it is known she was left behind when the DeNile family went under the conspiracy, being subentende that she might have died. In The Ghoul Next Door, Nefertiti is said to be the girls' aunt. She has a tough relationship with her father and sister, though the case is way more serious with the latter. 


At the beginning of the series, Clawdeen's angry with Cleo for dumping her brother Clawd, but now Cleo and Clawdeen are best friends and on the fear squad together. She's friends with Ghoulia Yelps, and they even plan their school schedules together.[2] Ghoulia often serves as Cleo's personal assistant ("Copy Canine", "Mad Science Fair"), but also shows her great kindness as well. She's sometimes bossy and demanding to the other ghouls, but she's also shown to be afraid of opening herself up to deeper friendships and making herself seem vulnerable. As the series has progressed, she has mellowed out and become much nicer and GFFs with the other ghouls.


Hissette Sticker

Cleo de Nile's pet is a snake named Hissette, whose attitude reflects Cleo's. In the Monster High book series, Deuce gave Hissette to Cleo as a gift, saying she was his mom's 'first gray hair', yet in her diary, it was stated that it was given to her as a gift from Egypt. In the books, Cleo also has seven cats named Chisisi, Bastet, Akins, Ebonee, Ufa, Usi, and Miu-Miu. This is a reference to how cats were worshipped by people and cherished and treasured, especially by royalty, in Ancient Egypt.


Cleo's dating Deuce Gorgon, whom makes her feel at ease and makes her want to be a better person. His and Hers Tips from Monster High's Royal Couple She used to date Clawdeen Wolf's older brother Clawd, but according to Ghoulia it was a messy breakup. She said that it doesn't help that Cleo started dating Deuce the next day.[3] The relationship between Clawd and Cleo, however, was only the result of C.A. Cupid's arrows. Even if Deuce occasionally gets tired of her competitive personality, his feelings for her are true. It states in C.A. Cupid's SSS diary that Cleo and Deuce started dating on November 1st.



  • We learn in "Hiss-teria" that Cleo is afraid of spiders. This comes up again in "Escape From Skull Shores".
  • The hieroglyphs on Cleo's vanity translate to Klio, the first part of how the real-life Cleopatra's name was spelled. In Ancient Egyptian, there is no letter representing an "e"-sound and phonetically the "e" in "Cleopatra" was and is treated as an "i". Meanwhile, Ancient Egyptian had three letters for "k", one for the "c/k" sound, one for the "kh" sound, and one for the "q/k" sound. Cleopatra's name was spelled with the latter "k".[4]
  • Her and Deuce's anniversary is November 1.
