Sailor Tin Nyanko

セーラー・ティン・にゃんこ

Sailor Tin Nyanko is the fourth Sailor Animamate to appear. In the anime, her human pseudonym is Nyanko Suzu, a name derived from her Senshi title and the Japanese word suzu, which means both "tin" and "bell." The term Nyanko is a colloquialism for a cat, originating from nyan, the Japanese equivalent of meow. In the English manga, her pseudonym is Kitty Bell.
In the manga, Tin Nyanko appears in Act 45 as a new transfer student from Libya. Like Lead Crow, she confronts individuals from her home planet, Mau—specifically Luna and Artemis. Diana arrives and attempts to protect them, but Tin Nyanko's Galactica Puppet attack transforms all three into their humanoid forms, injures the crescent moon markings on their foreheads, and turns them into ordinary, badly hurt cats. Sailor Star Fighter attacks her; although she escapes unharmed, she is subsequently killed by Galaxia. It is revealed that Sailor Tin Nyanko killed Sailor Mau, the Senshi of her home planet. According to the Materials Collection, Tin Nyanko also possesses the ability to manipulate scents and supposedly has nine lives.
In the anime, Tin Nyanko appears in Episode 188 as a rival to Sailor Lead Crow and Sailor Aluminum Siren. She is partly responsible for both of their deaths and, in the process, learns Sailor Moon's identity. During their confrontation, Sailor Moon attempts to heal her, succeeding only in knocking off one of her bracelets. This allows Nyanko's true personality to partially assert itself; however, she is torn between her duty to kill the Sailor Senshi and a new urge to rebel against her master. Symbolically, this also turns half of her uniform white. Sailor Galaxia resolves the situation in Episode 195 by removing the remaining bracelet. When Tin Nyanko dies, she leaves behind a small golden bell that had been part of her uniform.
