Sailor Mercury owned a compact supercomputer which she could use to scan her surroundings and analyze data, often proving very useful in battle. The computer was given to her by Luna. In episode 45, Sailor Mercury used the supercomputer to determine that the jewel one of the DD Girls wore on her forehead was the source of illusions they were using against the Sailor Senshi, then used the computer to destroy the jewel. After that, she was never shown using it again in the series, although it did make an appearance in the Sailor Moon R movie.
- Throughout the first season, whenever Sailor Mercury used the supercomputer the following messages appeared on the screen:
- Serve The Public Trust
- Protect The Innolent (deliberate misspelling of "Innocent")
- Uphold The Law
- Fans of the movie RoboCop will know that these are the three Prime Directives programmed into Officer Murphy.
