Petz was a member of the Black Moon Clan and the oldest of the four Spectre Sisters. She accompanied Rubeus and her sisters to 20th-century Earth in order to locate Chibiusa and find the Silver Crystal.


In the anime, Petz was stubborn, short-tempered, and haughty. She held a great deal of contempt for the people of Earth and, sometimes, even for her own sisters. In particular, she got into arguments with Calaveras every time the two of them worked on a target together. Although she appeared to be particularly fond of Berthier, since the two of them were usually able to talk calmly together, this was possibly due to the younger sister's use of flattery; Berthier, unlike the other sisters, never mocked Petz for failure even when she had the opportunity. Despite the fact that she almost never went on a target run, she believed that she was the best sister and would be the one to capture Chibiusa.

Petz did not take rejection well and would often show her anger in various ways, even with the slightest bit of failure. Compared to Calaveras, with whom Petz often worked, Petz was rather forceful and scornful, and therefore did not attract as many targets as Calaveras could with her natural gift of persuasion.

After two of her sisters went to Sailor Moon's side, Petz was given the chance to eliminate all of her sisters with the Black Moon Stick, as it increased her power so that she could kill the Sailor Senshi, Koan, and Berthier. She did indeed attack them, as well as Calaveras, but she was ultimately stopped by a team effort on the part of the Sailor Senshi. At that point they learned that the Stick had always been intended to kill Petz off as well. Realizing that she had been betrayed, Petz then felt remorse for her previous actions and tried to channel all the Dark Power she had left in her body into an attack in order to destroy the Stick from a distance. She was then sucked into the vortex, and after being saved by the sisters she had previously viciously attacked, Petz accepted Sailor Moon's offer of healing and became human. Petz and her sisters eventually started a makeup stand and lived together in an apartment in apparent harmony.

Petz reappeared in episode 86, where it was revealed that she loved Saphir. She kept his regal clothing after he died. She would be the last sister to appear in the series.


  • Black Moon Stick - A weapon given to Petz in episode 72 by Rubeus, which greatly amplified her powers.
  • Dark Power - An attack similar in appearance to Dark Thunder, which Petz used to try to destroy the Black Moon Stick.


Petz appeared in Act 17 of the manga, and was in charge of Code 003, Operation Re:New, the Black Moon's plan to kill off citizens with a supervirus and replace them with Droids, thus changing the future. When Sailor Jupiter confronted her, Petz vowed revenge for the deaths of Koan and Berthier, and trapped Sailor Jupiter inside a wind pocket. Sailor Moon killed Petz, but was unable to stop Sailor Jupiter's abduction by Rubeus.



Petz was played by Ai Ikegami in the musical Tanjou! Ankoku no Princess Black Lady and by Karen Yoda in its revision.


  • Evil Black Crystal earring - Petz used her earrings' powers as in the manga.
