The are the
commanders of the Dark Kingdom working directly under Queen Beryl. They provide the major
antagonistic force for the beginning of every version of the series. Before the events of the series, the Four Kings of Heaven originally functioned as the four guardians of Earth's
crown prince Endymion. They were led astray during the time of the Silver Millennium, selling their souls to the Dark Kingdom and becoming Beryl's servants. When reincarnated in the 20th century, they again fall prey to her and obey her every command, but retain a sense that they need to seek out their real master and aid him. The Sailor Guardians fight and kill the four of them, one at a time. However, they are all briefly revived near the end of the "Dark Kingdom" arc and are able to remember the Golden Kingdom and their time as Prince Endymion's guardians before being turned into the stone from which their names are derived. The stones are kept by Mamoru Chiba (Endymion's reincarnation in the present day) who uses them to call upon the spirits of the Four Kings of Heaven for advice on a situation. In the original anime adaptation, the Four Kings of Heaven serve as Beryl's servants and have no connection to Mamoru. Once they are killed, the four only appear in flashbacks afterward. In the DIC English adaptation, the Four Kings of Heaven served as human-like beings from the Negaverse, an alternate dimension of evil, and had only a vague understanding of human ways. The Four Kings of Heaven appeared in several musicals. In many of them, they are paired with the Sailor Guardians. In musical adaptations of the last arc, the Four Kings are revived by
Sailor Galaxia to work under her service, but in some versions, they betray her. The musical
Kakyuu-Ouhi Kourin had a group that which called themselves the Neo-Four Kings of Heaven (''Neo-Shiten'ō
). The members of the Neo-Four Kings of Heaven were Kunzite, Hematite, Hiddenite, and Kalunite. Hematite, Hiddenite, and Kalunite looked identical to Zoisite, Nephrite, and Jadeite respectively. In La Reconquista'', the Four Kings of Heaven disguise themselves as a boy band known as Pandemic 4. The group consisted of Kunza, Jed, Nephra, and Zoi. The band appeared in the Pandemic Love game, in which they used the game to drain energy for Beryl, and had one song, . In the live-action series, their past becomes more frequently seen. In the
Sailor Moon: Another Story video game, the Four Kings of Heaven appear as ghosts who help four of the Sailor Guardians get the respective gems of each of the Four Kings of Heaven when Mamoru ends up injured by the Opposito Guardians. In
Sailor Moon Crystal, the "Four Heavenly Kings" are kept alive beyond their deaths in the manga. They rediscover their past lives but are once again brainwashed by Beryl. During the final battle, Venus reveals that the Sailor Guardians and the Four Heavenly Kings were originally lovers much like Serenity and Endymion respectively. When the Sailor Guardians manage to reach the Four Kings during the former group's assault on D-Point, they regain their full memories before being obliterated by Queen Metaria for outliving their usefulness.
Jadeite is the first of the Four Kings of Heaven to appear. In her
Materials Collection,
Naoko Takeuchi describes him as 'a typical beautiful person' and a ruthless, serious type. He is about 18 years old in appearance, making him the second-youngest, while in the live-action series he is the youngest. He is the head of the Dark Kingdom's
far-eastern division and is named after the mineral
jadeite. Jadeite's mission is to track down the Silver Crystal but eventually changes to gathering life energy to awaken Metaria. He has very little interaction with the other Four Kings of Heaven. He expresses an attraction to
Sailor Mars and is the first one killed when Rei uses her
Akuryo Taisan technique. After Jadeite's death, Nephrite vows to exact revenge as he preserves Jadeite's skeleton in a glass coffin. In the later side story
Casablanca Memories, Zoisite also tries to avenge Jadeite. In the original anime adaptation, hunting energy is Jadeite's primary mission. He uses the alias "J. Dite" during his missions and has his Monsters pose as different people. After Jadeite fails numerous times and at one point costing Beryl the life of Thetis, one of her top Monsters, Beryl gives Jadeite one final chance to destroy the Sailor Guardians and threatens him with
Eternal Sleep should he fail. Upon Jadeite's failure, Beryl fulfills her promise and condemns him to Eternal Sleep by freezing him in a large crystal. She then warns everyone present to let Jadeite's fate be a warning to all of them before appointing Nephrite to be the monsters' new commander. In the live-action series, Jadeite is totally subservient to Beryl, for which she rewards him with her favor, sending him on missions that range from gathering energy to spying on his fellow warriors to attacking the Sailor Guardians directly. He disappears early in the series, reverting to crystalline form due to an injury from one of his battles, but is revived by Metaria. Firmly loyal to Beryl, he rejects Endymion as his true master until the series finale, where he stays with Beryl as the castle collapses around her. In
Sailor Moon Crystal, Jadeite survives the battle against Sailor Mars, but Beryl sends Nephrite to continue fulfilling their mission. In his past life, he was the love interest of Sailor Mars. Jadeite is killed by Metaria along with the other Kings of Heaven in Episode 12. In the original Japanese series, he is voiced by
Masaya Onosaka. In
Crystal, he is voiced by
Daisuke Kishio. and his mortal alias to Maxfield Stanton, and he is voiced by Kevin Lund. In the
Viz Media English adaptation, his voice is supplied by
Liam O'Brien. In the live-action series he was portrayed by Hiroyuki Matsumoto, and was portrayed in the stage musicals by Toshikazu Seike and Karen Yoda.
Zoisite is the third of the Four Kings of Heaven. Of the four, his character has undergone the most drastic changes from version to version of the story. He is the youngest, at about 16–17 years of age, described by Takeuchi as the least mature and most effeminate. He is introduced along with Nephrite, mocking him in each episode. At one point when Beryl spared Nephrite from Eternal Sleep due to bringing energy despite failing to take out Sailor Moon and Tuxedo Mask, she told Zoisite to remember his position and to focus on finding the Silver Crystal. Later, he orders her Monsters the Plant Sisters to kidnap Naru and kill Nephrite. The Plant Sisters succeeded in their mission. After Metaria's awakening, Beryl appoints Zoisite to find the Rainbow Crystals, fragments of the Silver Crystal sealed within the "Seven Great
Monsters". He obtains the seven crystals from the hosts of the Seven Great Monsters. Mamoru saves Usagi from certain death by intercepting Zoisite's attack. The two are then revealed to be Princess Serenity and Prince Endymion. Infuriated that Zoisite has injured Endymion, Beryl uses an attack from her scepter to fatally wound Zoisite who later dies in Kunzite's arms. In the live-action series, Zoisite is a pianist, using magical songs to hunt for the hidden Moon Princess. In addition to his own "Requiem for a Princess", he plays such compositions as the "
Fantaisie-Impromptu" and the "
Moonlight Sonata". He cares very little for Beryl and comes to recognize Prince Endymion as his master long before the others. After being killed by Sailor Venus and later revived by the power of Metaria, he ignores Beryl and uses his music to attempt to reach out to Endymion and to restore the memories of their collective past life to his fellow Kings of Heaven. His loyalty to Endymion is such that he offers his own life in exchange for the Prince's, and when Beryl asks for Usagi's life instead, Zoisite sets out to kill her. Diverted from this course of action by Endymion, he dies protecting Sailor Moon instead. In
Sailor Moon Crystal, Zoisite is wounded by Usagi's
Moon Healing Escalation technique. However, Beryl nurses him back to health. He attempts to kill both Mamoru and Usagi, only for Minako and Artemis to seriously wound him again and cause him to flee. In his past life, Zoisite was the love interest of Sailor Mercury. He is killed by Metaria along with the other Kings of Heaven in Episode 12. In the original anime series, Zoisite is voiced by
Keiichi Nanba, with
Masaya Matsukaze taking over the role for
Crystal. In the DIC English adaptation, his name is spelled as Zoycite, and he is voiced by
Kirsten Bishop as part of being depicted as a female character. In the Viz Media English adaptation, his name is spelled as Zoisite and his voice is supplied by
Lucien Dodge. In the live-action series, he is portrayed by Yoshito Endou. In the musicals, he is portrayed by Toshitaka Akita, Misao Idono, Akira Tomemori, and Kaname Aoki.
Kunzite is the fourth and final member of the Four Kings of Heaven. He carries a
shortsword, and Takeuchi describes him as having the majesty of an
Arabian king. He is the oldest, at about 25–26 years old, leads the Dark Kingdom's
Mid-Eastern division, and is named after the mineral
kunzite. Unlike the others, he wears a white cape in addition to his uniform, with his tunic partially opened. Before the beginning of the series, Kunzite is a military officer of Prince Endymion before joining Beryl and dying in the battle against the Silver Millennium. He is then revived by Beryl. Introduced as Zoisite's advisor, Kunzite becomes Beryl's henchman after the death of the other Kings of Heaven. He defeats the Sailor Guardians at Tokyo Tower and nearly kills Usagi, but Mamoru takes the injury for her, and they are revealed to be Princess Serenity and Prince Endymion. Remembering that Endymion is his former master, Kunzite becomes uncertain about his loyalties, causing Beryl to plant a crystal in his forehead that reduces him to little more than a mindless slave. During that time, Kunzite tells Mamoru where Metaria's weakness is. In the original anime adaptation, Kunzite and Zoisite are allies as well as lovers. After Metaria's reawakening, Kunzite assists Zoisite in obtaining the Rainbow Crystals. After losing the Rainbow Crystals, Kunzite is spared when Zoisite is killed at the hands of Beryl for harming Prince Endymion. She forewarns Kunzite to let what happened to Zoisite serve as a warning to him should he harm Endymion. Zoisite dies in Kunzite's arms. He resents being forced to work with the brainwashed Endymion because he feels he is responsible for Zoisite's death and because of Beryl favoring him. Following Zoisite's death, Kunzite plans to exact revenge on the Sailor Guardians and turns humans into Monsters to help him. Eventually, he captures all of the Sailor Guardians except for Sailor Moon. Kunzite is killed when Usagi reflects his own energy blade back at him as he tells Zoisite to wait for him on the other side. In the live-action series, Kunzite is first introduced in the form of an
amnesiac man named Shin, whom Usagi attempts to befriend. His memories are restored by Beryl, causing him to be a ruthless and powerful warrior. His efforts to reawaken Metaria are largely motivated by a desire for personal gain, and he is dismissive to Beryl, sometimes to the point of insubordination. He mostly works with her toward their shared goals, and he also transforms Sailor Mercury into Dark Mercury. Kunzite is awakened early on to the memory that Endymion was his master in his previous life, but he feels extreme contempt for the prince, believing he betrayed the Four Kings of Heaven in ages past and left them for dead. Eventually, at the cost of his life, he saves Endymion from an attack by Jadeite and professes his loyalty to the prince. In
Sailor Moon Crystal, Kunzite turns off Tokyo's power to provoke Minako into attacking him. However, he flees with Mamoru and is rejoined by the other Four Kings of Heaven. In his past life, he was the love interest of Sailor Venus, a fact which Venus desperately tries to remind him of each time they face off. In his last moment prior to being killed by Metaria along with the other Kings of Heaven, he manages to briefly acknowledge that he returns Venus's love. In the original Japanese series, he is voiced by
Kazuyuki Sogabe until episode 44 of
Sailor Moon, and by
Eiji Takemoto in all media following
Sailor Moon Crystal. In the DIC English adaptation, his name was changed to "
Malachite" and he is voiced by
Denis Akiyama with
John Stocker as a
stand-in during a clip show in
Sailor Moon R. In the Viz Media English adaptation, his voice is supplied by
Patrick Seitz. In the live-action series, he is portrayed by
Akira Kubodera. Kunzite was portrayed in the stage musicals by
Yūta Mochizuki, Ryuji Kasahara, Hideka Asano, and Miki Kawasaki. ==Servants==
