Lucy is described as being kind, charming, plucky and strong. However, she still displays the symptoms of someone who has been programmed by the Vault-Tec Corporation, such as when she bluntly asks Monty about his sperm count. Due to her bubbly personality, she says "okie-dokie" in a myriad of situations, such as whenever she approves something, when she does not get what she wants, or even when doing something mentally challenging such as having to behead a corpse. While this shows her optimism, it may also hint at Lucy instinctively suppressing her true emotions, or her method of coping. Lucy strongly believes in the Golden Rule, which is to treat others as one wishes to be treated.

Lucy has also lived a privileged life without needing to deal with the roughness of the wasteland. She is also said to be naive due to her upbringing, as her only experience with the outside world has been through what she learned in the Vault and read in books.

Lucy is confident that she can change things for the better, fueled by her optimism of the retro-America she was raised to admire. An optimistic hard-worker, Lucy has an inherent belief that humanity is generally good, and that there is goodness in the world which can prevail over the evil in it. However, she struggles to maintain this belief the more she explores the wasteland, becoming more cynical as she becomes aware of suffering, violence and death. Her personality goes through a transformation when she finds herself betrayed and attacked by humanity, making her tougher and wiser, even if she becomes emotionally overwhelmed sometimes.
