Jadeite (SMCU)

Jadeite was one of the four Knights of Endymion and the first of the four Dark Kingdom Lords to be introduced.

Prior to the Cinematic Universe
Prior to the fall of the Moon Kingdom 1,000 years ago, Jadeite was one of the four Knights of Endymion who served under Prince Endymion I. He is designated as the Knight of Patience and Harmony. After being brainwashed by Queen Beryl, he became one of the Dark Kingdom Lords, along with the other three Knights of Endymion: Nephrite, Zoisite and Kunzite.

Jupiter’s Quest
Jadeite faces Makoto and Minako at a museum in Rome, where he releases the snake-like Youma Serpens. The Youma is eventually destroyed by Sailor Jupiter’s Supreme Thunder.

The Sailor Moon Movie
Jadeite, along with the other Dark Kingdom Lords, is banished to another dimension by the spirit of Queen Serenity.

Lost in Space
Jadeite was destroyed by Sailor Starfighter’s Star Serious Laser.

Sailor Crusade
Jadeite and the other Dark Kingdom Lords are eventually revived and recruited by Sailor Galaxia (who is controlled by Chaos) with other major villains of the Cinematic Universe as members of the Shadow Galactica Legion. Eventually, he and the other Dark Kingdom Lords are purified by Tuxedo Mask and reinstated themselves as the Knights of Endymion after realizing that Tuxedo Mask is in fact the reincarnation of Prince Endymion II.

Later, Jadeite and the Knights head to the Phantom Dimension where they battle the nine Chaos Knights. During the battle, the environment of the Phantom Dimension caused their physical selves to dissolve and eventually obliterate the Chaos Knights. Although their physical bodies have perished, their spirits/souls survived the battle.

In the film’s end credits scene, Jadeite’s spirit can be seen playing “Moonopoly” with the souls of his fellow Knights, only to be joined in by the spirit of Professor Souichi Tomoe, who died in the Second Sailor Crusade while protecting his daughter Hotaru.

Another Story
Jadeite’s spirit and the spirits of his fellow Knights drop by at Usagi’s house to inform them about Mamoru Chiba’s condition. Mamoru was struck by an attack by a mysterious entity named Sin, and in order to cure him, the Rose Crystal is needed. To claim the Rose Crystal, the Knights’ stone gates scattered across the globe must be opened with stone keys made of their respective color stones. Jadeite’s gate is located in Hong Kong, and must be opened with the Jadeite Stone Key, given by him to Sailor Mars and her team.
