After falling in love, the Cyborg Duchess merged with the spider to become the Spider Duchess. Shortly after being "born", she began detecting something large coming towards Iris's TARDIS. The large creature revealed itself to be a giant Walrus, and attacked the Cyborg Duchess' friends. She killed the Walrus, but lost her some of her legs in the process. Because of this, she stayed behind in the arctic wastes of Hyspero. (PROSE: The Scarlet Empress)
