The Black Moon Clan is the name of a villain group in the "Black Moon Arc" and in Sailor Moon R of Sailor Moon. They are an evil organization originating from the planet Nemesis in the 30th Century. Using the Evil Black Crystal, they attacked Crystal Tokyo, pursuing the Silver Crystal. They eventually traveled back to 20th Century, pursuing the Rabbit.
The members of the Black Moon Clan have black upside-down crescent moons on their foreheads in comparison to the Silver Millenium's marking of the rightside-up gold/white/silver crescent moons. Also, the members of the Black Moon have diamond-shaped earrings made out of the Evil Black Crystal that allow them to teleport.
They are referred to as the NegaMoon Family in the North American dub.
The Black Moon Clan consists of mainly:
- Prince Demande
- The Ayakashi Sisters
- Black Lady
Droids were units used by the Black Moon Clan. In the manga, all of the droids were all similar looking in shape and form, and only able to produce screeches, while in the anime, they were all unique and were able to talk.
The Ayakashi/Spectre Sisters used the droids in order to fill a Crystal Point with dark energy. Esmeraude did the same thing, but also ordered them to guard the Dark Wedge she implanted in the specific location.
