Changes from the Manga

  • In the manga, Setsuna thought that Chibi Chibi was Usagi's daughter from the future.
  • Chibi Chibi's name was given unintentionally by Ikuko Tsukino.
  • Sailor Lead Crow and Sailor Aluminum Siren didn't team up in the manga, and they never had civilian disguises either.

First Appearances



  • This episode included the first speaking roles of Sailor Lead Crow and Sailor Aluminum Siren.
  • This was the first appearance of Sailor Pluto in one of the episodes of the fifth season's main arc.
  • The decision to have the phage called "Sailor Cop" encased in metal may have been inspired by the Robocop series of films.
