Seven Great Youma

The Seven Great Youma were the seven strongest demons that served Queen Beryl during the attack on the Silver Millennium. With a few notable exceptions, they were anime-only characters.

Information

The Seven Great Youma were introduced in anime episode 25 when Queen Metalia revealed that the Silver Crystal had encased them after the battle on the moon. After being trapped, the crystal shattered into seven colored pieces, each holding a youma, and they disappeared on Earth, reincarnating as normal humans. Queen Beryl then charged Zoisite with locating and extracting each crystal piece, using a special homing crystal (which had previously belonged to Nephrite).

The search for the crystals lasted seven episodes, and each battle for a crystal piece normally began when Zoisite, sensing the crystal piece, would appear in front of the piece's holder and use the homing crystal to extract the crystal right from the carrier's heart. The extraction tended to be slow and painful for the victim, and when the crystal was finally extracted the person reverted to their Great Youma form, attacking the sailor soldiers who came to stop Zoisite from getting the crystal piece. Once the youma was weakened, Sailor Moon would not kill it, but would instead use Moon Healing Escalation to re-seal the youma inside them.

Later, in anime episode 41, Queen Beryl sends Prince Endymion with the homing crystal to recapture the seven holders, in order to combine them into one invincible super-youma the sailor soldiers would have been incapable of defeating. Endymion was able to capture six of them before Sailor Mercury fought him and destroyed the crystal, thus thwarting the Dark Kingdom.

List of The Seven Great Youma

The following is the list of the Seven Great Youma, as well as their human forms, their crystal color and the party that eventually won the crystal piece prior to anime episode 34:

Gesen -> Crane Game Joe -> red -> Zoisite

Boxy -> An unnamed priest -> orange -> Tuxedo Mask

Bunbo -> Ryo Urawa -> yellow -> Sailor Moon, then Zoisite

Vena -> Yumemi Yumeno -> green -> Zoisite

Rikoukeidar -> Reika Nishimura -> blue -> Zoisite

Jiji -> Rei's Grandfather -> indigo -> Zoisite

Bakene -> Rhett Butler -> purple -> Tuxedo Mask

Of these, two of the characters - Reika and Rei's Grandfather - appear in episodes beyond the Seven Great Youma plot, are characters which were created by Naoko Takeuchi and appear in the manga as minor characters. The rest are anime only, as the Seven Great Youma plot is anime only.

All the rainbow crystal carriers appear briefly in episode 41 and Ryo appears as a character central to that episode as well, and in episode 45, the DD Girls create an illusion of Ryo Urawa. Other than that, none of them, except the two listed above, are mentioned again.
