Quartet in line. When the Quartet begins to develop sympathy for the Sailor Guardians and destroy their balls, Zirconia escapes to Nehelenia's mirror. Though able to break Queen Nehelenia from her mirror, Zirconia is destroyed upon serving her purpose. Zirconia is voiced by Hisako Kyōda and Naomi Watanabe in the Crystal film, Sailor Moon Eternal. In the Cloverway English adaptation she is voiced by Robert Bockstael and her gender is changed to male. In the Viz Media English adaptation and the Netflix English dub of the Eternal Movies, she is voiced by Barbara Goodson. Queen Nehelenia , leader of the Dead Moon Circus, is named after the ancient goddess Nehalennia. Nehelenia is like the dark mirror image of Queen Serenity; the self-styled Queen of the dark center of the Moon that existed since Silver Millennium who possesses the ability to inflict powerful curses. She made herself known at the celebration of Princess Serenity's birth, the confrontation that followed ending with Queen Serenity sealing Nehelenia within a mirror. Nehelenia used her final moments of freedom to curse the Moon Kingdom to fall before Princess Serenity could take the throne, making her the cause of Silver Millennium's destruction. With the Moon Kingdom no more, as she used a solar eclipse to breech her seal, Nehelenia decided to focus on conquering Earth. Several millennia later, taking the Sailor Quartet to serve her as the Amazoness Quartet, Nehelenia conquers Elysion before sending the Dead Moon Circus to defeat the Sailor Guardians and retrieve the Silver Crystal from Sailor Moon. Once the Sailor Guardians managed to defeat all of the minions, Nehelenia makes her presence known as she confronts the Sailor Guardians in Elysion and takes the Silver Crystal.
