Lucy has no personality points, or skills. When resurrected, she comes back with a male voice, provided by voice actor Stephen Kearin, because she is recognized by the game as a male. This can be fixed with SimPE. Lucy is one of the few ancestral Sims to die as an adult, so she died a premature death. According to her age data, she had 29 days left in the adult life stage when she died. When editing in SimPE, Lucy's zodiac sign is not recognized.
She uses the 12th Maxis face template in Create a Sim, except the ears and mouth which use the 4th face template. Also the jaw is customized, being longer than on the default, though it is only longer on adults and elders, which may mean that the jaw was genetically passed down, as this oddity generally only occurs on Sims whose facial features were genetically passed down.
Lucy bears a huge resemblance to the Diva, as they both have the same hairstyle, hair color, skin tone, eyebrows, eyes, and nose. Even though she is thin, her fitness bar indicates that she is supposed to be fit. This is a very common occurrence among Sims with an ambiguous gender and/or age.
