Catsy is the most aggressive of the four sisters. She requests very little help from droids, and she doesn't mind fighting toe to toe with the Sailor Scouts. Her distinguishing features are the cat ears in her hairstyle, and the sorry looking tutu. She is also very obsessed about her looks, especially her face.

Rubeus is a servant of Wiseman, from the Dark Moon of the Negaverse. His mission is to find whatever means there are of destroying the future city of Crystal Tokyo, and to execute those plans. He usually hands down those individual assignments to the four sisters that he brought into the past with him.

Prince Demando is the ruler of the Black Moon Family. In the future he tryed to get Neo-Queen Serenity to be his Queen. He later attempted to capture Chibi-Usa. When Sailor Moon arrived in the furture he tryed to get her to become his Queen, she refused. He later realized that Wiseman had lyed to him. Wiseman tryed to kill Sailor Moon but Demando took the hit himself and died shortly after in Sailor Moon's arms.

Safiiru is Demando's younger brother. During Demando and Safiiru's childhood Demando told Safiiru about how they would take over Earth and punish the people of Earth for banishing their ancestors. Safiiru was caught up in a power struggle between Demando and Wiseman. Safiiru tryed to stop Wiseman by himself and stole the key card that ran the Black Moon Crystal. He was regarded as a trader and killed by Wiseman. As he died, he told Demando how Wiseman was deceiving him.

Wiseman is the ruler of the Dark Moon. In order to take over Earth (in the future) he sends Rubeus back in the past (to our present day) to destroy the city of the future known as Crystal Tokyo.

Esmeraude was Rubeus's successor. Her plan was to destroy Tokyo with statues of herself that gave off atomic blasts. She later returned to the Black Moon and told Wiseman to make her the Queen. Wiseman made her a tiara and placed it on her head. It was not to be and she became a Dragon. She left Black Moon palace and went to Crystal palace to destroy the Senshi. She failed when Tuxedo Mask's rose struck her tiara. She then fell into a black void and died.

Black Lady was created by Wiseman to be Queen of the Black Moon. She was kidnaped by Wiseman when Chibi-Usa walked outside of the force field of the Crystal palace. She was turned into Black Lady after bad memories where implanted into her brain. Black Lady tryed to destory the Senshi but was destroyed when Sailor Moon transformed into Neo-Queen Serenity and told her she was not alone. Black Lady was destoryed and Chibi-Usa was back not normal.
