Eclipsa Butterfly

Eclipsa Butterfly (voiced by Esmé Bianco) (also known as Eclipsa the Queen of Darkness) is a character in the Disney XD animated series Star vs. the Forces of Evil. She is the former and current ruler of Mewni.

Eclipsa has short, poofy teal hair, grayish-purple eyes, pale skin, and red spade-shaped marks on her cheeks. She wears a long, dark purple Gothic-themed dress, a large black sun hat with gray and white feathers and a thorny branch, a white cravat with a lavender crescent moon on it, and gray opera gloves. Eclipsa also has maroon-colored lipstick and black mascara. Underneath her gloves, her hands are dark purple with purple veins sprouting out on her arm.

Little is known about Eclipsa, but what is revealed indicates a dark and/or less-than-respectable reputation. In "Into the Wand", a tapestry of Eclipsa is shown among the past and present Queens of Mewni. According to a passage inscribed on the tapestry's pedestal, Eclipsa was wed to a Mewman king, but she was already in love with a monster named Globgor. Eclipsa later eloped with this monster and had a Mewman/monster hybrid child named Meteora (the true identity of Miss Heinous), who was switched with a peasant child, Festivia, by the Magic High Commission.

During her life, Eclipsa developed a number of spells that were associated with dark magic. These spells were recorded in the pages of the wand's Magic Instruction Book and sealed behind a skull-shaped lock to prevent others from reading them. She was also the only member of the royal family who never questioned Glossaryck's teaching methods. According to Baby, Eclipsa had a very high affinity for magic compared to the other queens, rivaled only by Star herself. It is also presumed from a remark by River Butterfly that Eclipsa harbored sympathy for Mewni's monsters, a sentiment shared by very few of her fellow Mewmans and royals. At some point before the events of "Crystal Clear", Eclipsa was apparently encased inside a crystal by Rhombulus. Her crystallize imprisonment kept her alive for three hundred years, and at some point met Moon Butterfly. Rhombulus briefly unfreezed part of her body so Moon could ask Eclipsa for a spell that could defeat Toffee. Eclipsa was willing to help, but in return wanted her freedom once her enemy was destroyed.

Eclipsa is portrayed as calm, approachable, and sympathetic, despite her reputation as a queen of evil. (She was only branded such because of her extreme "outside the box" beliefs. Even the Magic High Commission admitted to sealing Eclipsa in crystal "before she could do anything [evil]"; even though Eclipsa's only crime by law was abandoning her arranged husband King Shastacan.) She bears no ill will towards her jailers, despite her long time in crystal captivity, and displays a carefree, fun-loving attitude similar to Star. She maintains her calm demeanor further on in the series, and is more than willing to help Star whenever she is troubled. She also has a fondness for chocolate bars and roses.
