Eclipsa Butterfly, also known as the "Queen of Darkness" from Star Vs. The Forces of Evil is a misunderstood, caring, protective, playful mewman who, after spending years trapped and sealed away, is now on the castle of the Butterfly Kingdom under supervision of the Butterfly family. Due to her relationship with a monster and her practice of dark magic, she is generally held with suspicion, fear and antagonism. That being said, she is calm, polite, patient, open-minded and non-conformist.
