Sailor AluminumSiren, who is know as Aya Reiko in her civilian form, was the third of Galaxia's minions known as the Animates. She appeared in ep. 182, and was killed in ep. 188.|
When AluminumSiren gets upset or nervous, she eats, and to be polite, she hands out cards to introduce herself.
It was the job of the Animates to gather StarSeeds. AluminumSiren, from what I've seen, came the closest to capturing SailorMoon's StarSeed.
When AluminumSiren was introduced she was viewed as a rival to LeadCrow. However I believe that their relationship resembles that between Usagi and Rei, in that they are very close friends. (Even if they fight a lot.) Like when TinNyanko got killed AluminumSiren LeadCrow wept for her.
The Animates are not really evil. [Ok, I know I had said that they were Senshi, however, I was partially wrong.]They joined Galaxia, stealing their power from the Senshi of their planet, AluminumSiren's being the planet Mirmaid. This made her a Senshi by default.
