Lucy is the hero's landlady in Custom Robo (GameCube). She is usually the one waking him each morning. She starts off having no experience with custom robos, but she later commands the robo Tank Head in the Grand Battles and manages to become a very skilled commander. She was also supposedly known to be a supermodel and a peanut-sneezing champion. She is somewhat flirty, and even jokingly talks to the hero about getting married and having children.
