Queen Moon Butterfly is a supporting character in the Disney XD animated series, Star vs. the Forces of Evil. She is the former Queen of the Mewni alongside her husband, River Butterfly, and Star Butterfly's mother. She was the previous wielder of the Royal Magic Wand before passing it down to her daughter on her fourteenth birthday.

As of season 4, Moon is no longer queen of Mewni, the throne having been passed from Star to Eclipsa Butterfly, and much of her memory is in fragments as a result of exposure to the Realm of Magic (though it seems to be fully restored by "Ghost of Butterfly Castle").

As of "Moon Remembers", she and River have left the kingdom to start a new life and formed a community of Mewman refugees.

In "Pizza Party", she regains the wand and the title of queen from Eclipsa, but after the age of queens and magic came to an end in "Cleaved", she, once again, is no longer queen.



Queen Butterfly is serious most of the time, having a low tolerance for anything messy or destructive. Despite being the queen, Queen Butterfly acts as the true ruling monarch of Mewni and always has the well-being of her kingdom in mind, to the point she is unable to express interest in anything else. This often causes her to appear cold toward others. Despite her overbearing strictness, she truly loves and cares for her daughter.

In her youth, Moon used to be just like her daughter, a "Happy go-lucky girl", but after Toffee killed her mother and she inherited the throne, she became serious and mature to protect her kingdom and family.

Physical Appearance

Queen Butterfly has a slender figure and taller than her husband. She has long pale blue hair with three bangs that resembles her daughter's, often shaped in a heart. She has blue eyes, wears pink lipstick, and purple diamonds on her cheeks. She wears a golden crown with a purple diamond in the center. Her royal outfit includes a light blue and periwinkle gown, the skirt somewhat resembling the shape of a heart, with long blue gloves.

From "Mr. Candle Cares" till Season 3, Queen Butterfly had slightly altered her look; her crown now has a gold diamond-shaped attachment with a purple diamond in the center, from which two strings of pearls curl around the sides of her hair. Her ears are visible, and wears gold diamond-shaped earrings with purple diamonds embedded in them. She now wears purple lipstick.

In her Mewberty form, Moon has large butterfly-like wings and six arms.

After letting go of her role of being queen in "Moon Remembers" onward, her hair style is changed to a long braid and wears a short sleeved sky blue dress.

Powers and abilities

  • Royal Magic Wand: Moon Butterfly was once the owner of the royal magic wand, and she once used it to permanently sever one of Toffee's fingers.
  • Mewberty form: Moon can change into her Mewberty form at will. She has blue skin, six arms, and large butterfly wings capable of flight.
  • Inherent magic: As a queen of Mewni, Moon has magic deep within her body that she can access by "dipping down". With this reservoir of magic power, she can fire energy from her hands and create magical constructs such as whips, barriers and energy swords.
  • Swordsmanship: Moon has proven to be proficient with both regular swords and energy swords created with her magic.
  • Telekinesis: In "The Bogbeast of Boggabah", Moon levitates Star off the ground. In "Tough Love", she levitates mud and large boulders.
  • Baking: "Butterfly Follies" and "Escape from the Pie Folk" show that Moon has a talent for making pies.
