Moon Butterfly

Queen Moon Butterfly (also known as Moon the Undaunted) is a supporting character in the Disney XD animated series, Star vs. the Forces of Evil. She is the ruler of the Mewni alongside her husband, King Butterfly, and Star Butterfly's mother.

Background
She was once the previous owner of the Magic Wand before passing it onto her daughter on her fourteenth birthday. She is known to be serious most of the time, having low tolerance for anything messy or destructive, which is why she disapproves of Star's reckless and irresponsible behaviour.
