Tin Nyanko, under the alias Suzu Nyanko, is quite possibly the most evil out of all the anima-mates. She is quite the suck-up and so easily convinces Galaxia to kill Siren and assign her work. She dislikes waste and believes Crow to be waste as well. Nyanko kills crow and almost gets the "real" star seed out of them all - Usagi's silver crystal. She's quite diligent and so comes close to getting the star seed several times. Usagi heals her halfway and so she turns half white, half black. Her white half is good and has no bracelet, her black half is as she was. Being at only half power, she still tries to get the star seed but her good half always interferes and she ends up arguing with herself. Galaxia, in the end, gets rid of her.
