Lust is first introduced in episode 1, where she is in disguise as a visitor in the town of Liore. She and her partner in crime, Gluttony, who is pictured to the left, had given a fake Philosopher's Stone to the priest tyrant Father Cornello, in hopes that alchemists would flock from all over the country to see if was real. Lust finds alchemists from all over the place and teases them into searching for the real Philosopher's Stone by giving them fake ones, allowing the alchemists to feel the basics of the power the real stone could provide, causing them to develop a desire to search for the real one. Lust wants the real Philosopher's Stone for only one purpose. After Edward Elric exposes Cornello, she allows Gluttony to eat the crazy tyrant. In the original manga, she killed Cornello herself by turning her fingers into daggers and piercing Cornello in the head.
