Mirror

Mirrors appear throughout Sailor Moon and in the manga at least two Sailor Senshi derive some of their powers through mirrors. Though in other versions this only applies to Sailor Neptune.

Mirrors Used by the Sailor Senshi

Minako Aino/Sailor V/Sailor Venus

Minako Aino's compact had a mirror in it and it only showed the true forms of those who were reflected in it, so it could be used to reveal disguised Dark Agency agents and always showed Minako's reflection as Sailor V. In the Codename: Sailor V Sailor V used it in many of her attacks, especially Crescent Beam and the more powered up versions of Crescent Beam which utilised light reflected by it. This item only appears in Codename: Sailor V and in the Sailor Moon manga.

Michiru Kaiou/Sailor Neptune

Sailor Neptune's talisman was the Deep Aqua Mirror, like Minako's mirror it could reveal hidden truths and was used in the attacks, in this case Submarine Reflection.

Mirrors Used by Enemies of the Sailor Senshi

The Black Moon Clan

The Black Moon Clan made use of mirrors in the R season of the anime, specifically Rubeus and the Phantom Sisters used Mirrors as portals in their UFO.

The Dead Moon

In the SuperS season of the anime the Dead Moon were searching for Pegasus who was hidden in beautiful dream of an individual, to find him the Dead Moon members had to search the Dream Mirrors of people who they thought may be the one Pegasus was hidden in. This plot element was not present in the manga, however the Dead Moon where still tied to mirrors as in both the anime and the manga Queen Nehellenia was trapped within a mirror.
