  '''Bertie '''is one of the [[Negamoon Sisters]]. She has white hair and attacks with dark water that can freeze things. In the&nbsp;Japanese version, her name was '''Berthier'''.
  
  == In the anime ==
  Bertie is the first one sent by [[Rubeus]] to take over crystal points in Tokyo. She tries this twice, and the droids she used were [[Droido]] and [[Frosty]]. However, both droids were destroyed by Sailor Moon.
  
  After [[Catzi]] switched sides, Rubeus sent Bertie to take over a crystal point in a chess building. Amy encountered Bertie and transformed into [[Sailor Mercury]] to fight her, revealing her true identity to her. Bertie left the battle and entered the chess tournament, where she faced Amy in the finals. Although Amy won, Bertie trapped the other Sailor Scouts and started another game of chess with Amy, except this one was a freeze play - whenever Amy lost a piece, she would be frozen. However, the spell was shattered by Tuxedo Mask, and Bertie's plan was foiled. After hearing from [[Avery]] and [[Prizma]] that Rubeus was going to kick her out for her failure, Bertie attempted to use her power to freeze herself, but Catzi stopped her and convinced her to turn good, so Sailor Moon used Moon Crystal Healing Activation on her. Afterwards, she and Catzi played a game of chess.
  
  Bertie was later captured along with Catzi by Avery and Prizma, in an attempt to turn them evil again, but in the battle that followed, Rubeus ditched Avery and Prizma and Sailor Moon used Moon Crystal Healing Activation on them.
  
  Bertie is the second of the Negamoon Sisters to turn good.
