She is the last of the Anima-mates and she doesn't feel sorry for Siren and IronMouse. Further TinNyanko (she calls herself Nyanko) is perfidious. Although she tells Galaxia that he wants to cooperate with SailorLeadCrow she does her best to put Crow into the shade. When SailorLeadCrow is surrounded by the senshi TinNyanko tries to blast Sailormoon from behind using a bazooka which is shaped like a tiger's paw. Later she is jealous because LeadCrow has found another victim and doesn't want her help. So she ties and gags LeadCrow to take her place as a judge  in a contest. Further she dogs Crow's steps when she goes for Sailormoon's star seed. She is the one who blasts Crow so that she loses the black hole and dies. Later she tries to take Sailormoon's star seed herself but Fighter helps Moon and Eternal Sailormoon attacks TinNyanko with "Silver Moon Crystal Power Kiss". SailorTinNyanko loses one of her bracelets and withdraws. When she comes back she is only half evil. Her dark side wants to attack Sailormoon but her good side warns the senshi and even offers Galaxia to take her life instead of the senshi's.  Because she is of no use for Galaxia any more, Galaxia takes her second bracelet and TinNyanko is no more.
