Petz is the eldest of the Spectre Sisters who works for Rubeus.


Petz has long dark green hair that is wrapped up in an updo and bun, and has dark green eyes. Her outfit consists of a sleeveless short dress with a decorative bodice and black fur on her shoulders. She wears a black belt with the buckle off the side of her hip, long green gloves, black leggings and short boots.

When a part of the black moon, she has the upside down crescent moon symbol on her forehead and the black crystal earrings, just like her sisters.

After she and Calaveras were purified by Sailor Moon, Petz is usually seen wearing corporate business attires when she and her sisters are running the cosmetic shop as well as treating Saphir's serious injuries.

Sailor Moon R

Petz's first mission against the Sailor Guardians was to send Droid Furaiki to create a thunderstorm to drive Usagi and Chibiusa out of hiding. After Furaiki was destroyed, Rubeus began sending Petz and Calaveras on missions together to take over crystal point, but each of their plans, aided by Droids

Furaiki, Jamanen, Avocadora, and Akumuuda, were foiled. After Koan and Berthier turned good, Rubeus sent Petz and Calaveras to turn them evil again, and gave Petz the Black Moon Stick. This strobe made her ten times more evil than before and she turned on Calaveras. The Sailor Senshi all defeated her and knocked the strobe out of her hand. When Rubeus activated its power to form a portal to suck everyone into another dimension, Petz volunteered to jump into it to destroy it, but was stopped by Calaveras, and the Sailor Senshi destroyed the strobe. Afterwards, Sailor Moon healed Petz and Calaveras with Moon Crystal Power.

From here, Petz ran a cosmetic shop with her sisters and she constantly scolds Berthier for doing her everyday make up during their business and being remarked by her as being old and grouchy. It is later revealed that she is in love with Saphir. Petz and her sisters found Saphir when he was injured by Wiseman. Her fears that Saphir would be killed if he attempted to warn his brother of Wiseman's treachery were well-founded, as Wiseman killed Saphir. She kept his regal clothing after he died.

It is unknown if she is revived afterwards.
