From the oracle Manga: When Luna and Artemis see her, they recognize her and call her a "fake cat." She then reveals herself as Tin Nyanko, from the same planet as Luna and Artemis, Mau. Luna and Artemis scold her and call her a traitor for giving in to the enemy - but Nyanko retorts, saying that they are the ones who are traitors, because they abandoned their home planet. Tin Nyanko can no longer change to her cat form, because of Galaxia's bracelets. She becomes infuriated with Luna and Artemis, and consumed with the desire to destroy them. She informs them that their planet, Mau, has been destroyed by the Shadow Galactica Empire. The Materials Collection states that she manipulates scent, has nine lives, and is about the same height as Sailor Moon.
