Beryl is Queen of the Negaverse and loyal servant to the evil Negaforce. She desires to rule the Earth, seeking revenge on Princess Serena, the Sailor Scouts and Queen Serenity, for her actions during the Silver Millennium. Queen Beryl was also jealous that Prince Darien's heart belonged to Serena. She brainwashed him and he became a Negaverse warrior, loyal to Queen Beryl. Beryl is impatient, demanding, and a merciless ruler who does not tolerate mistakes or failure. She expects and demands homage and complete obedience from her servants & doesn't think twice about sacrificing any of them. Queen Beryl’s powers are impressive but her body is quite weak. After she is gravely wounded by Prince Darien’s red rose, she pleads for help from the Negaforce. The Negaforce provides her with immense power & during her final confrontation with the Moon Princess, Queen Beryl is vaporized by the power of the Imperium Silver Crystal.
