The Amazoness Quartet clearly signifies that there are three other members besides PallaPalla, hint hint. I don't like them as much as my lil crazy fiend, but this is for those of you who can comprehend "quartet" and want to know about the rest.
VesVes-She's the girl in red with the bony shoulder pads. She is equal to Sailor Mars. VesVes is the most serious and head-honcho type of the Amazoness Quartet. She's pretty bossy and always tries to act tough. She even challenged Zirconia's authority once! (You go girl!) She's the animal tamer of the Dead Moon Circus, and carries around a whip. Down, boy! Heel! ^_^. In the manga she becomes Sailor Vesta (goddess of the hearth, FYI) of the Sailor Quartet.
JunJun-JunJun's the one who looks like birds could nest in her hair >XD. Her equal is Sailor Jupiter. Not only in power, but also in athletic ability. JunJun is the acrobat of the Dead Moon Circus. There's not much about her personality; she seems to be snobby like the others. In the manga she becomes Sailor Juno (roman goddess of matrimony, I think, wife to Jupiter).
CereCere-She's my favorite after PallaPalla. CereCere is the equal of Sailor Venus. She prefers to use flowers in her ploys, and has successfully put the Amazoness Quartet to sleep with her flower powder before! She's very snobby and likes to think of herself as rich and elegant. Whenever she's in human form carrying out a dream-mirror taking job, she's always dressed very expensively. In the manga she becomes Sailor Ceres (greek goddess of grain).
