Enemies No More


Sibling Rivalry

"Checkmate" is the 24th episode of Sailor Moon R. It was preceded by Enemies No More and followed by Sibling Rivalry.


Rubeus sends Bertie to take over a crystal point located in a chess building, where Amy is going, as she is good at chess. Amy encounters Bertie and transforms into Sailor Mercury to fight her, revealing her true identity. Sailor Moon and Sailor Jupiter arrive, forcing Bertie to retreat.

Bertie decides to enter the chess tournament, as Amy is going to be entering it as well. Serena, Raye, Lita, Mina, and Catzi are in the audience cheering for Amy, who advances to the finals with Bertie. Amy wins, but Bertie freezes the camera and traps the other Sailor Scouts, before doing a "freeze play" game of chess with her, in which Amy gets frozen as she loses pieces. Tuxedo Mask breaks the spell, and Avery and Prizma tells Bertie that she has been kicked out for her failure.

Bertie uses her power in an attempt to freeze herself along with the entire room, but Catzi tells her to join her instead, and Sailor Moon uses Moon Crystal Healing Activation on her.

The episode ends with Catzi and Bertie playing chess.
