|"I am a de Nile! And I'm not going to let a teeny set-back keep me from my destiny!!"|
|—Cleo de Nile to Twyla in "13 Wishes"|
Cleo de Nile is a 2010/2016-introduced and all-around character. She is a mummy and a student at Monster High. She's the queen bee at school, and the most popular girl, as her status as an undead Egyptian princess gives her relevancy over the others. Daughter of Ramses de Nile, she was second in heir to be a pharaoh, if it wasn't for the fact that she died and she has an older sister Nefera de Nile. She lives in a palace-like temple with hundreds of loyal servants in the middle of New Salem (Salem, Oregon in the books by Lisi Harrison).
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 analogues who received creative interpretation by the video crew. The mummy girl is played by Megan Mackenzie.
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. Her singing voice is Firoozeh Scoot.
She was portrayed by Megan Nicole in the YouTube video of the Monster High special song "Digital Monsters, We are Proud".
Cleo was a princess of Egypt over 5,800 years ago and raised to a wealthy royal household, young and happy. One day, a delegation from a far-off country arrived and gifted her sister, Nefera, a corpse flower that was claimed to be a rare treasure only fit for royalty. However, one day her uncle committed a coup d'état that had been perfectly planned, leading her family to be adviced to flee underground. Despite that the queen had yet to join them, Ramses de Nile already had the family wrapped with magic cloth that would keep them safe while their loyal followers would deal with the usurper. What they didn't know was that they had no loyal followers left and that the magic cloth was meant to keep them asleep forever. Nonetheless, they woke up after 1,300 years, only to find the queen still missing and themselves trapped within the hiding spot. As Ramses began to spend his days looking for an exit, Cleo pessimistically enjoyed the luxuries of their prison, but Nefera was hit badly by both the loss of her mother and her future and spent most of her time talking to her corpse flower, that she'd taken with her. An earthquake eventually damaged the prison enough to create a hole, allowing sunlight in. As the family rejoiced, the corpse flower awakened from her slumber and introduced herself as Amanita Nightshade. She explained what truly happened during the coup d'état, revealed that the family had been asleep for 1,300 years, and elaborated that they now no longer fit the human world but must find their place in monster society. When a caravan passed by, the De Niles' shouting was not enough to draw attention, but Amanita was thin enough to get through the gap and promised to return with help. She never did and the family eventually got out on their own.
About 4,500 years later, the family has relocated to New Salem, Boonighted States of Scaremerica. Though the throne of old is gone, the family has access to a large collection of magical artifacts that only works for them and over 10,000 servants, most of which apparently ushabti. Cleo has easily adapted to her monster life, enjoying the riches of her temple and enjoying the life of an high-schoolar at Monster High, the prestiged school of the Boo World, eventually finding interest Clawd Wolf, the co-captain of the basketball team, only to later dump him for his co-captain Deuce Gorgon, where she found love, that made her ascend in the social pyramid, making people realize that she was also a princess, making her incredibly popular, enough to join the fearleading squad led by her sister, that, because of this, elected her for captain when she graduated. Since then she's been either famous for her success and status or infamous for her less-than-kind 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.
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: she is easy to be taken by the insecurity of not being fit for leadership, 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.
She can work well with the others if they share a common goal, in which case she becomes the de facto leader of the ghouls. She's a highly effective organizer and a leader who will deviate between acting selfishly and selflessly, depending on her mood, which is easy to alter, as she is a tad tempered, when fueled, and violent if upset. Additionally, she is stubborn and will only follow her rules if she feels like it, and she lacks when it comes to learning from her mistakes, making the same mistakes of dodging responsibility and attempting to control others. It doesn't help she has access to limited amounts of magic, through her magical amulets. In the webisode series of Monster High, Cleo is mainly known as the Queen Bee at school, having self-proclaimed popularity which is not untrue despite being self-proclaimed. Despite Cleo's personality overall, one of her true personality traits is that she is kindhearted deep down with a true heart of gold, which is much more than what can be said about her sister Nefera, who, when asked about best friends in her profile bio, only said she "rule[s] alone". Cleo also solely goes by the name Cleo in the Monster High without the adding of the family name "de Nile" to not raise suspicion to her name resembling the Egyptian name Cleopatra and having a name that has to do with the river, the Nile, which is what her surname is based on. Though her full name is never actually said, as in, "Cleo de Nile", it is hinted at, especially when Brett Redding, calls her "Queen of de-Nile" as a pun on the river Nile and the word "denial", and her father is referred to as "Ramses de Nile" in the beginning of the second book.
Cleo de Nile is in the possession of dark brown hair, which is commonly enhanced with golden highlights, although she also picks blue, teal, and/or purple as additional colors, but she typically wears it with gold streaks made of real gold and not just golden, which also has some black streaks in it. 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 which may or may not be a birthmark. Though, in the original Monster High franchise and Generation 1 of Monster High by 'Basic' doll, and cartoon, it appears she has naturally black hair with natural medium-brown streaks and golden-colored streaks made of real gold.
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.Fortunately for her, she is allowed to apply the burial wrapping in whatever way suits her. This may or may not be exclusive to the Facebook content and doll lines. 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, lotuses, snakes, and triangles (pyramids).
- Banshee Scream: Cleo can scream very loudly like Operetta can because it is the ability acquired by the race mummy.
- Serpent Charming: Like her sister Nefera, she can charm snakes.
- Scarab Charming: Like Nefera, Cleo can also charm scarab beetles.
- Mummy Wrap Power: Through her mummy heritage powers, she has the ability to wrap others in bandages and spread out bandages, such as seen in "Welcome to Monster High", she was seen spreading out her wrappings onto a gravestone to trip the Zomboyz. This is an ability only acquired in the 2016 reboot. It is certainly unknown if it will ever be brought up again in 2017 of the reboot.
- Amulets: Although it is not her innate ability, Cleo can use their rodzinych idols and amulets. Though not dokońca reigns over them, it often happens that accidentally releases the various plagues that rotate against her. For instance, when hairs lost by excessive use one of them.
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. Cleo and Nefera's mother is mentioned in her Gloom and Bloom Diary. She was left behind when the De Nile family went under the conspiracy. She is confirmed to be alive at the end of Hexiciah Steam's and Robecca Steam's diary, though it is unknown what happens to her after. 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 more serious with the latter. Nefertiti in Monster High is most likely a book-only character to the Lisi Harrison series. The aunt most likely exists in the monster world version of the real-life world in Monster High, since Ramses de Nile is a clear reference to the mummy Ramses or Ramesses as an alternative spelling in Egyptian mummy mythology history possibly Ramesses II, and Cleo's name is clearly based on the mummy Cleopatra, but the mummy Nefertiti who might be the actual Nefertiti in Egyptian history is probably not related to Cleo nor her elder sister.
Cleo's within the most popular students at Monster High, a status that has adquired her a vast list of followers, but her list of close friends isn't too big, as she initially faced friendships has despensible, as long as she's treated like she best pleases. 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.
So, she finds a best friend in Ghoulia Yelps, and they even plan their school schedules together. Ghoulia often serves as Cleo's personal assistant ("Copy Canine", "Mad Science Fair"), and Cleo forgets at times to give Ghoulia respect, usually taking advantage of her submisive nature and her smarts. Despite this, she has learned how to treat Ghoulia like a friend rather than a servant, specifically after "Fright On!". The two trust each other and do almost everything together, Ghoulia helps Cleo with academic achievings while Cleo protects Ghoulia from any harm and makes sure she's "someone", though Ghoulia really couldn't care less about her popularity.
Out of the three permanent members, Cleo seems to be closer to Clawdeen, the most mature of the three, something she respects. However the two didn't start all that good. Cleo used to date Clawdeen's brother, Clawd Wolf, who she dumped, leaving a grudge between the two divas. Clawdeen didn't trust Cleo and Cleo looked down on lowly Clawdeen in their begginings, however when the two grew closer they discovered they have more in common then they previously thought. Despite Clawdeen not standing Cleo's bossy nature and her dramatic reactions, the two are popular and fans of high fashion, fierce and confident, and work very well together. So much that Clawdeen has become sorts of an inspiration to Cleo, with her hard work and free creativity.
Cleo can get easily furstrated with both Frankie's and Draculaura's antics, both being the most immature of the crew, with overly excitement and positivity in them, which Cleo appreciates but also gets slightly annoyed with. She also had a hard time to adapt the clumsiness of the two, who to top it off weren't the most skilled cheerleaders to begin with. However, she will do anything to protect them and loves them with all her heart. Like with Clawdeen, Frankie's and Cleo's mutual relationship didn't have smooth begginings, with Frankie, accidently, embarrasing her twice, once by insinuating her boyfriend was actually Deuce.
Lagoona is the other member of their clique that is close to Cleo. Though interactions between the two are rare, Lagoona is just as sympathetic and friendly towards her as she is to the next one, though Cleo is probably the one out of the main six she is the most hostile towards, though not in big amounts, sometimes being sassy and lecturing her, though only when Cleo is inconsiderate. As the voice of reason and the most down to earth of the gang, Cleo definitely trusts her and enjoys her company too.
Among Cleo's less close friendships lie Jinafire Long, her wise, advice-giving roommate, that is living in her palace while the exchange program carries on; Abbey Bominable, her foreign friend who she kind of thinks lowly of but still adores, especially as a competition partner; and Twyla, who goes against her expectations of being popular during the high school year but whose selflessness has helped Cleo at time, usually giving her advice and wise words. According to her profile bio, she is best friends forever with her boyfriend, Deuce Gorgon and with Ghoulia Yelps.
Despite her friendships, Cleo's popularity and personality have gained her several nemesis too, the most prominent one being Toralei Stripe and the werecat twins, Purrsephone and Meowlody. It all started when the werecats swore to make use of what they learned in delinquent prison, to overthrow those who rule, this being Cleo, the queen bee. Then, when Nefera chose Cleo over Toralei for squad captain, despite the difference in experience that would otherwise benefit Toralei, the rivalry between the two sparked for real, and the werecats gave up on the squad to make their own, to rival Cleo's yet inexisting squad. What they weren't expecting was the success of the replacements Cleo found, and were tempted to join again, though Cleo refused. Since then they're faithful to their promise to make Cleo's, and the Fear Squad's life a living nightmare, playing pranks and framing them on a daily basis. Cleo and Toralei act hostile to one another and constantly insult each other, cat fighting usually and throwing shade at each other, a toxic relationship of cat vs. rat. However, the two have shown signs of harmony when working together, and it is implied by Neighthan Rot that their problem is the lack of communication. Despite this, they can't stand each other no matter what.
Gory Fangtell is another opponent. Fresh from Belfry Prep, where Gory was the captain of the cheerleading squad, she's not willing to give up her status, and developed a low-key rivalry against Cleo, when her ambitions were denied.
Amanita Nightshade, her fellow "friend", also has a low-key rivalry, though she is much more subtle about it. She's sly with her insults, acting like she doesn't know what's going on. She has no specific reason to torment Cleo, she just enjoys it and the chaos it brings. Cleo can't stand her however, and for valid reasons, due to their unfortunate past, and because Amanita's "oblivious" façade annoys her to the core. She has suffered enough because of her and isn't willing to forgive her that easily or take up with her, though she has stated she'll try.
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, Cleo stated that she was 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 worshiped by people and cherished and treasured, especially by royalty, in Ancient Egypt. She has a new Egyptian cat whose name is not released on the doll box in the reboot.
Cleo is currently dating Deuce Gorgon and the two of them are the 'it' couple on campus. She says he makes her feel at ease and makes her want to be a better person (via ). She previously dated Clawdeen Wolf's older brother Clawd. According to Ghoulia, it was a messy breakup and it didn't help that Cleo started dating Deuce the next day. However it is later revealed that the relationship between Clawd and Cleo was the result of C.A. Cupid's arrows. The effects masked Cleo's interest in Deuce until the spelled couple broke free, after which Cleo pursued her real feelings for Deuce. Cleo has stated that she believes that she and Deuce were "made for each other"  and enjoys spending time with him, even if they are just playing video games or making a home cooked meal . While Deuce occasionally gets tired of her competitive personality, his feelings for her are true. C.A. Cupid's SSS diary states that Cleo and Deuce started dating on November 1st.
In the reboot of Monster High in Welcome to Monster High, she and Deuce first meet through Monster High. It begins rocky when Deuce petrifies her by accident. Throughout the special she ignores Deuce, even when he helps her, until the end when they save one another from Zomboyz. Not much is said between them but warm looks are shared at the movie's end.
