Cleo de Nile/Generation 1

"If I gave apologies, I would give you one right now."

- Cleo de Nile in "Here Comes Treble"

Cleo de Nile is the daughter of The Mummy and is 5,842 years old (give or take a few years). She is going out with Deuce Gorgon. She is the captain of the Fearleading squad at Monster High.

Portrayers
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.

Personality
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 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.

Appearance
Cleo de Nile's a mummy in the possession of long black hair with brown (which varies in shade in the webisodes and on the doll) and gold highlights. Her skin is mocha colored, smooth and flawless. She has turquoise eyes, though they've also been depicted as green. Many parts about her points to her regal heritage, such as her ever-present burial wrappings, which she has to wear lest she disappear into dust, and a blue jewel under her right eye. Generally, she wears thick bright eyeshadow, highly pigmented lipstick (cherry red, gold, blue, green), and always wears thick black Egyptian-style winged eyeliner.

Family
Cleo lives with her father, and older sister, Nefera de Nile. Her dad's name is Ramses de Nile, and he's an antiques dealer. So far, nothing is known about Cleo and Nefera's mom. In The Ghoul Next Door, Nefertiti is said to be the girls' aunt.

In the webisode "Miss Infearmation", Cleo mentions having an older sister called Nefera de Nile, who's out of the country with their father. Clawd's School's Out diary also mentions Nefera being the previous fear squad captain. Nefera is said to be a model in Cleo's School's Out diary. Based on both the School's Out diaries and the cartoon, Cleo and Nefera don't get along very well.

Friends
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. 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.

Pet
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.

Romance
Cleo's dating Deuce Gorgon. She used to date Clawdeen Wolf's older brother Clawd, but according to Ghoulia it ended badly. She said that it doesn't help that Cleo started dating Deuce the next day. 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 diary that Cleo and Deuce started dating on November 1st.

Appearances
In "New Ghoul @ School", Cleo starts out with a dislike of Frankie Stein after she accidentally tripped over her entering a classroom, and also electrocuted her handing her a pen to sign a petition. Then, when letting Frankie try out for Fear Squad, she gets covered in Ghoulia's drink after Frankie's hand lands in it and splashes it all over her. However, she decides to give Frankie a second chance through an interview, which is ruined when Frankie lies and says she's dating Deuce Gorgon, Cleo's boyfriend, which causes Cleo to run out of the room and accuse Deuce of cheating on her. Frankie manages to explain that it was all a mistake, and Deuce was never cheating on her, and makes it up by organizing a private Justin Biter concert.

In Fright On!, Cleo develops her own rivalry with Gory Fangtell, and drags in Deuce to compete with her and Bram's relationship. She also starts to treat Ghoulia less like a friend, and more like a servant, akin to the traditional way vampires treat them. So, in the end, she realizes how horrible she had been acting and apologizes to both Gory and Ghoulia.

In Why Do Ghouls Fall In Love?, she and Clawdeen become take to planning of Draculaura's Sweet 1600 birthday. During the party, she is shot by one of Cupid's arrow and sees her reflection, effectively falling in love with herself.

In Escape From Skull Shores, Cleo goes with the group to the Great Barrier Reef (after a disappointing carnival in which Deuce won less prizes for her than Clawd won for Draculaura), but is sidetracked when the boat is destroyed and are forced to ride with Bartleby Farnum to Skull Shores. Much to her dismay, she is stuck with several tasks such as cleaning and cooking while the rest are given jobs like decorating. She also becomes increasingly jealous of Frankie's 'royal treatment'.

In Ghouls Rule, Cleo's relationship with her father becomes slightly strained when it is revealed he strongly disapproves of Deuce. To add injury to insult, the school is also dealing with demeaning Halloween pranks by normie kids. She decides to please her father by becoming the makeshift leader of a group assigned to get back at the normies. Earning her father's approval for standing up what she believes in, she also loses Deuce's when she breaks up with him for not supporting her, again as akin to her father's ideals. She also takes advantage of Holt being accused of vandalizing the normie school by lying and saying that he sent her an email confirming that he was, in fact, guilty of the crimes, and that he would continue to update his exploits through his Critter account, with Cleo being named his 'spokesprincess'. It is soon found out that Cleo was responsible for the lies, along with Lilith Van Hellscream, and the ghouls, with the help of Clair and Chad, instigate a confrontation between the two where they find common ground in fashion, and come clean. They then admit to the sheriff, who decides not to take any action in freeing Holt to show that hes capable of bringing 'justice'. The group manages to free Holt, and bait an angry normie mob to the Hall of Halloween where a party was waiting for them. Cleo apologizes to Deuce and the two continue their relationship, which she makes sure her father heard the entire conversation and refuses to comply to him anymore.
