31 Days of Halloween: Cleo de Nile (Monster High)

Cleo is daughter of the Mummy (better known as Ramses de Nile) 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's also head of the fear-leading squad and one of the power couples of the franchise. Originally she and her family was once Normies but her family went under a conspiracy led by her father's closest advisers, and so her father, her sister and her had to flee and be mummified in a dark room, with magical bandages. She stayed asleep for 1300 in the room, making her the oldest of the group at the age of 5,842 (give or take a few years).
