Beryl
In a far past, she had a crush on the Moon Princess's boyfriend, and started a war out of jealousy. Now, all she remembers is that she wants revenge, and that Metallia is going to help her in exchange for a little energy.

Jadeite
Queen Beryl's first energy-gatherer, a ruthless, cold, calculating character who is nevertheless considered rather pathetic by his colleagues.

Nephrite
Queen Beryl's second energy-gatherer, who uses the stars to pick out a victim. As cold and calculating as Jadeite, but with more interpersonal skills.

Zoisite
King of Fire, and a very jumpy little fellow. Gatherer of the Moon crystal, or more precisely, of its fragments.

Kunzite
The aptly named King of Ice, he only unbends to Zoisite. Less than impressed by his miniskirted adversaries.
