Eclipsa Butterfly (also known by her title The Queen of Darkness) is a major supporting protagonist in the Disney TV series Star vs. the Forces of Evil who debuts as the false main antagonist of Season 3 (the true main antagonist being her daughter Meteora).
She was introduced as the Darkest Monarch in the Butterfly Dynasty history. Upon her debut she served as an advice-giver to Star, with it being very ambiguous as to whether or not she was truly evil.
She was voiced by Esmé Bianco.
