The Amazoness Quartet are the second group of villains from the Dead Moon Circus. Their mission is to find the Golden Mirror that Pegasus is hiding in. They spend most of their time playing or getting massages from invisible people wearing gloves and coats instead of looking for the Golden Mirror. They also like to chase Zircon, Zirconia's floating eyeball-with-wings.
When they find a target, they use a pool stick and their colored cue balls to knock out the target's dream mirror. This is usually very interesting to watch, because the cue ball usually bounces off three or four walls before finally hitting the target from behind and knocking out their dream mirror. Then, since the dream mirror is never the Golden Mirror that they're looking for, they summon a lemure. The lemure eats the dream mirror, and is then destroyed by Sailor Moon, and everyone except the lemure lives happily ever after.
Before they were part of the Dead Moon Circus, the Amazoness Quartet lived in a jungle. Then one day while they were playing, they found a magic mirror in a lake. The mirror talked to them and gave them their cue balls, which would keep them young forever so they would always keep their beautiful dreams. The mirror was the one that Queen Nehelenia was trapped inside. The Amazoness Quartet then became part of the Dead Moon Circus and worked for Queen Neherenia, trying to find the Golden Mirror.
