Rainbow Crystals

The seven Rainbow Crystals are seven crystals, the Imperium Silver Crystal split into seven. The Seven Shadows were each sealed inside it and vanished into Earth's atmosphere with them. Both the crystals and the shadows were reborn inside humans (and in one case, a cat) on Earth.

The red crystal was inside a man named Game Machine Joe, and the Shadow within him was a monster named Game Machine Man. Zoycite extracted this crystal first, and took it.

The orange crystal was inside a priest, and the Shadow within him was a monster named Bobo the Vulture. Zoycite extracted this crystal second, but Tuxedo Mask took it.

The yellow crystal was inside Amy's friend Greg, and the Shadow within him was a monster named Bumboo. Zoycite extracted this crystal third, but the Sailor Scouts took it.

The green crystal was inside an artist named Peggy Jones, and the Shadow within her was a monster named Veena. Zoycite extracted this crystal fourth, and took it.

The blue crystal was inside Andrew's girlfriend Rita, and the Shadow within her was a monster named Techniclon. Zoycite extracted this crystal fifth, and took it.

The indigo crystal was inside Raye's grandpa, and the Shadow within him was a monster named Pox. Zoycite extracted this crystal sixth, and took it.

The violet crystal was inside a cat named Hercules, and the Shadow within him was a monster named Bakene. Zoycite extracted this crystal last, but Tuxedo Mask took it.

Later, Sailor Moon was forced to hand over the yellow crystal to Zoycite.

Zoycite challenged Tuxedo Mask to a duel over the crystals, but Malachite appeared and took all seven, as the duel was a double cross. However, Sailor Moon's tears caused them to combine into the Imperium Silver Crystal.
