These girls should look familiar to you, if not they were the Amazoness Quartet. How is this possible do you ask, well you must rmemeber this isnt the first time we had a villian turn sailor. Long before they were the Amazoness Quartet they were future guardians of Chibi Usa (when she becomes Queen that is). Each girl belong to a different asteriod: Juno, Pallas, Vesta,and Ceres. Well as the story goes they were sleeping await the time when the new future Queen would need their help, but Queen Naherian had other plans for these Sailors. She awoke them and turned them into the Amazoness Quartet. But when Queen Naherian was starting to lose the battle against Sailor Moon she put the Amazones into the balls. After her defeat(Queen Naherian) Sailor Saturn asked Neo Queen Serenity to free them from their ball prisions. When she did they appeared as their true forms; Sailor Juno, Sailor Vesta, Sailor Pallas, and Sailor Cere. And then left to sleep until the future back in there asteriods.
