| Mercury Goggle in the anime
The Mercury Goggle was a transparent blue visor sometimes worn by Sailor Mercury in the anime, manga, and musicals. She could make it appear or disappear by touching one of her earrings, and used this item to scan and analyze enemies and phenomena in battle, as well as make calculations.
- In episode 13 of the anime, the Mercury Goggle displayed the words "Arrest Mode" in the corner of the display. This was a reference to the movie RoboCop similar to the one displayed by her Supercomputer.
