Description
Petz is a character from the Sailor Moon R storyline of the anime Sailor Moon, where she serves as one of the main antagonists of the Black Moon Clan arc. She is the eldest of the four Spectre Sisters, a group of female warriors who work under the command of Rubeus, and she is known as Prizma in some English versions. She has long dark green hair styled into an updo, dark green eyes, and wears an outfit of green and black with black fur on her shoulders, a black belt, long gloves, and black leggings. Like other members of her clan, she bears a black upside-down crescent moon on her forehead and wears black crystal earrings as symbols of her allegiance.

In terms of personality, Petz is proud, stubborn, short-tempered, and haughty. She is ambitious and willing to push others aside in order to achieve personal glory and power. She also carries a deep bitterness over a past romantic relationship, and she reacts sharply whenever her sister Calaveras teases her about it. This emotional wound helps explain why she is so guarded and abrasive, as she has never fully moved past being hurt by someone she once trusted.

Her motivations are tied to her loyalty to the Black Moon Clan and her desire to prove herself. She accompanies Rubeus and her sisters to 20th-century Earth with the mission of locating the young girl Chibiusa and recovering the Silver Crystal. She is driven by a sense of duty, competition, and pride, and she often clashes with Calaveras even though the two ultimately end up working together on most operations.

Petz's role in the story is that of a recurring enemy who challenges the Sailor Guardians during the first half of the Sailor Moon R narrative. After the two younger Spectre Sisters, Cooan and Berthier, are purified and turn away from the Black Moon Clan, Rubeus gives Petz a staff that infinitely increases her dark powers. He instructs her to use it to destroy both the Sailor Guardians and her former sisters, warning her that failure will mean she cannot return. The staff dramatically amplifies her magic, but it also corrupts her personality and makes her more aggressive, to the point where she turns on Calaveras and attempts to kill her along with the other sisters. However, the Sailor Guardians recover, knock the staff away, and restore Petz's normal level of power. Rubeus then reveals that he never expected her to succeed, and that his true plan was to lure the Sailor Guardians into a trap and sacrifice all four sisters. He activates the staff's full power, creating a massive time-vacuum that threatens to pull everyone into it. Freed from the staff's corrupting influence, Petz becomes remorseful and decides to throw herself into the vortex to destroy the staff and save everyone, but her sisters stop her. After the Sailor Guardians destroy the vortex, Petz and Calaveras are purified, meaning they are cleansed of their dark allegiance and allowed to live normal lives in 20th-century Tokyo.

Her key relationships are with her three sisters, especially Calaveras, with whom she has a tense but ultimately strong bond, and with Saphir, the younger brother of the Black Moon Clan leader Prince Demand. Later in the story, Petz and her sisters discover a wounded Saphir. Petz at first assumes he has come to punish them, but she tends to his injuries regardless. It is then revealed that Petz and Saphir were romantically involved in the past, and that Saphir is the person who caused her to become bitter and distrustful toward men. Their history suggests that her pride and harsh exterior developed as a defense against the pain of that relationship. When Saphir is killed by the villain Wiseman, Petz senses his death and is heartbroken, but she takes comfort in remembering how he smiled for her.

Her notable abilities include a magical power called Dark thunder in the anime, which connects her to storm-based attacks and makes her a counterpart to Sailor Jupiter, who also uses lightning. She summons powerful electrical attacks with this magic, and the corrupted staff given to her by Rubeus dramatically increases the strength and scale of her abilities. She is also shown using a UFO during her operations. Her development over the course of the story moves her from a proud and bitter antagonist into a redeemed figure capable of compassion, forgiveness, and sorrow, as she reconciles with her feelings for Saphir, experiences genuine remorse for her actions, and chooses to stand with her sisters even after losing the life she once knew.
