Cleo de Nile/Generation 1

Cleo is the daughter of the Mummy and is approximately 5,842 years old (give or take a few years). She is going out with Deuce Gorgon and is the head of the Fearleading squad.

Personality
Cleo is royalty, and expects everyone to treat her like it. She is stuck up, too. Usually, her attitude is selfish, spoiled, arrogant, and unkind. She is like this because she is an ancient princess and is used to being treated as high royalty. She is shown to be extremely competitive and downright difficult to get along with because of it as well. She has a rivalry with Clawdeen Wolf, which, according to Ghoulia Yelps's diary, began when Cleo dumped Clawdeen's brother, Clawd, and started dating Deuce Gorgon the very next day. Cleo enjoys tricking the other girls or getting them in to trouble, but her efforts usually fail.

However, she has been known to have a heart of gold on occasion. She is kind to Ghoulia Yelps and helps her to overcome her shyness. (Although she has been known to take advantage of Ghoulia and uses her as a personal assistant most of the time like having Ghoulia organize her schedule for her, or cheating off of her.) She has also done kind things for Ghoulia in secrecy, but refused to tell anyone because of her reputation.

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' and also complimenting her on her looks with the other ghouls), in which case she becomes the de facto leader of the gang. She shows she can be a highly effective organizer and leader, she just needs to learn how to get along better with others.

In the first season webisodes, Cleo is primarily played as an antagonist. However, in the second season she is finally confronted with her own uncompromising, overbearing nature when the regular Fearleading Squad resigns. Afterward, she slowly starts to become more accepting and accommodating toward Frankie and the ghouls.

When she gets really upset, Cleo lets loose a glass-shattering super forceful scream and strangely enough in more severe cases starts obsessively cleaning things, like polishing the trophies in the trophy case. This and her rigid perfectionism could be an indication of strong OCD.

There are also hints in the Webisodes about Cleo's fear of the dark, which she writes about in her diary.

Portrayals
In the webisodes and Monster High movie New Ghoul @ School, Cleo's voice is provided by Salli Saffioti, who ironically also provides the voice for Clawdeen Wolf.

In the music video for the Monster High Fright Song, there are several character analogues who received creative interpretation by the video crew. The mummy girl is played by Megan Mackenzi.

Physical Description
Cleo de Nile has flowing black hair with brown and gold highlights. She has dark, tanned skin, and blue eyes. She always wears a crystal birthmark under her right eye.

Classic Monster
Cleo de Nile is the child of Imhotep, the mummy from Universal's 1932 film The Mummy, directed by Karl Freund and starring Boris Karloff.

The story of The Mummy concerns an archaeological dig which discovers the remains of the Egyptian prince Imhotep. When a member of the expedition reads aloud the Scroll of Thoth, the mummy is brought back to life; he then spends his time searching for the reincarnation of his lover, an ancient princess.

While the princess in The Mummy looks very similar, the most famous portrayal of the character came from Elizabeth Taylor in 1964. Cleo de Nile's style clearly reflects the dark hair with bangs, jewelry and style, and certainly the haughty attitude of the Egyptian princess.

Family
Cleo lives with her father "in this palace that looks like a movie set with servants and all. . . .they're like rockstars or something." In the books, her Dad's name is Ramses de Nile, an antiques dealer. To date there is no mention of Cleo and Nefera's mother.

In the webisode Miss Infearmation, Cleo mentions having an older sister called Nefera de Nile (a reference to the Egyptian queen Nefertiti), who is out of the country with their Father. Clawd's diary as well mentions Nefera as being the previous fear squad captain. Nefera is said to be a super model in Cleo's School's Out diary. . Based on both the wave 3 diaries and the webisodes, Cleo and Nefera do not get on very well. However Nefera doesn't make an appearance in the books.

Friends
Cleo's attitude means she sometimes has an uneasy relationship with the ghouls of Monster High, but they are all friendly with her, except for Clawdeen Wolf. Clawdeen is angry with Cleo for dumping her brother Clawd, though they can be civil when required. In Cleo's schools out diary, they became "frenemies" after Clawd explained to Clawdeen what really happened between them, and in the webisodes they became friends on the fearleading squad.

She is particular friends with Ghoulia Yelps, and they even plan their school schedules together. Ghoulia often serves as Cleo's personal assistant (Fear Squad). Cleo sometimes takes Ghoulia for granted, and on several occasions takes advantage of her (Copy Canine, Mad Science Fair).Since Lagoona Blue is a warm-hearted person, she seems to get along easily with Cleo, and Cleo has never done anything bad to her.

Pet
Cleo de Nile's pet is a snake named Hissette, whose attitude reflects Cleo's. In the Monster High books she also has seven cats named Chisisi, Bastet, Akins, Ebonee, Ufa, Usi, and Miu-Miu. This is a reference to how cats were revered in Ancient Egypt.

Romance
Cleo is dating Deuce Gorgon. She used to date Clawdeen Wolf's 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 true story behind the break-up was revealed in Clawd's diary. It was actually more of a mutual agreement to split up, but Cleo insisted that everyone should think that she broke up with him for the sake of her social status, which Clawd implied that he thought was shallow and ridiculous.

Cleo de Nile in the Monster High books
In the book, Cleo is much nicer to the other girls, even Clawdeen (mostly due to their status as RAD's), with whom she made her first appearance with. You see her more with Clawdeen in the books. Apparently she was one of the most popular girls at Merston High, despite being a RAD. Bekka hates her because she kissed Brett, who was Bekka's boyfriend at the time. Also Cleo's name is Cleopatra de Nile in "Ghoul Next Door". Cleo and Melody have a constant feud, started with Melody accidentally bumping into Cleo in the school cafeteria. Cleo kisses Jackson, turning him into DJ, and Melody eventually starts using Deuce against her. Cleo helps out with Frankie trying to get the RADs out of hiding when she learns Deuce is going to the Monster Mash with Melody. Cleo also calls Melody "Melodork" in the first book and in the second book, although at the end she ends up trusting Melody. Her sister Nefera doesn't make an appearance.

In "Ghoul Next Door", she is one of the few monsters who are against the idea of human-monster equality. When she is offered a photoshoot for Teen Vogue, she does everything in her power to get her friends involved. When Brett's idea of a video is introduced, she hates the idea of it, mostly because it's the same day as her photoshoot. She does everything in her power to put an end to it, losing her friends in the process. When all hope seems lost, she forms and alliance with Bekka, which backfires when the uncensored video is aired. All her friends believe it was her doing.

Personality File
Cleo is haughty, demanding and regal which befits her royal linage. While she expects to be deferred to, she also possesses a certain noblesse oblige resulting in acts of great kindness and generosity on her part.

Parental Participation
Cleo's father is the chairman of the MH construction committee and oversees all new building plans. Publically he appears aloof and uninterested in the mundane happenings at MH but coincidentally much of the business he has here seems to correspond with the events where Cleo is involved.

Academic Standing
As a child, Cleo was tutored by the greatest in her father's kingdom. This tutoring has given her a broad knowledge of many subjects although she really excels in dead languages and geometry. Cleo's biggest hurdle has been the realization that we don't allow servants to do homework or take tests for our students.

Social Interaction
Cleo is a princess but she's not a mean ghoul. This has allowed her to establish genuine relationships with fellow students who can "let Cleo be Cleo" even when "her imperial bossiness" forgets that at Monster High she's just one of the ghouls.

Overall
Cleo de Nile has great leadership potential and seems to have escaped the traps that can turn rulers into tyrants. Cleo is the personification of a teenage monster with a pedigree who is learning that respect is based not on birthright but actions.

Cleo's Official Facebook Description
Cleo totally rules Monster High. She’s the daughter of The Mummy and her tightly wound wrappings are not only a sign of her monster heritage, but are also a royally awesome fashion statement. She has to be careful though – if she’s not wrapped in at least one bandage, she’ll disappear into dust. Technically, the ghoul is 5,842 years-old but is only now getting the chance to be a teenager (can you believe she was perfectly preserved in a royal burial chamber for thousands of years?). Thanks to many years in totally tight quarters, she’s way afraid of the dark… but don’t tell her I told you that. Her Egyptian cobra, Hissette can be a little ghastly from time to time, but I hear her hiss is way worse than her bite.
