Appearances in Other MediaEdit




  • Finola Hughes was considered for Diabolique's voice.
  • Diabolique was originally going to be killed off in Season 10, after Dracula tricked her into shooting Macbeth with her particle beam cannon, but the idea was scrapped due to Jack Mozenrath feeling it to be an unsatisfying end for the character.


  1. Olivia Colman voiced Diabolique in "Stone at Night".
  2. Confirmed by toy bio.
