Judas Liz made her first appearance at the end of Iron Liz' Star Wars RPG review, in which she was an unseen person killing a version of Liz and saying "Everything he sees, he conquers."
Afterwards, Judas Liz was seen on Lord Vyce's ship, talking about his plans. Judas Liz suggested that his emotions were impairing his judgment, which angered him into saying she was only there because their goals overlapped each other. Then when Linkara called him and started mocking him in order to get him to go back to where they were, Judas Liz slipped away.
Her final appearance was at the end of Iron Liz' review of Warhammer Fantasy: 2nd edition, killing off yet another version of Iron Liz.
