"What I want isn't money, pretty dresses, or fortune forced upon me. I'm not Lucky Lucy of Heartfilia anymore! Fairy Tail recognizes me as just Lucy and my other family, it's a far more loving family than this!"
— Lucy Heartfilia to her Father in "Goodbye"
Lucy has brown eyes and shoulder length blonde hair that is usually tied by ribbons in a variety of colors in a small ponytail to the right side of her head with the rest of the hair loose. However, in the year X791 she appears to keep her hair up more often in pigtails. She is buxom, and has a curvaceous body. Her (presumed) measurements are: bust, 91 cm; waist, 59 cm; and hip, 88 cm (36 in, 24 in, 35 in).These measurements were later revealed to be slightly different, with the breasts being two centimeters less, and the others one less. In X792, her hair is considerably longer, and she keeps it all in a side ponytail.
Her pink Fairy Tail stamp is located at the back of her right hand.Additionally, Lucy does not consistently wear the same outfit. However, she always has a belt that, along with keeping her skirt up, holds her Celestial Spirit keys and a whip with a heart-shaped end. She often wears black, leather high heeled boots. She also bears a striking resemblance to her mother.
Lucy takes exceptional pride in her appearance and is very confident in her sex appeal, often exuding a certain amount of vanity.Despite this superficial attitude, she is a clever, kind, and genuinely caring person. Lucy is passionate for literature and is in the process of writing her own novel about her adventures with Fairy Tail although she does not like telling anyone about it. Aside from her interest in writing and reading prose, she also likes shopping, cooking and assertive men. Her favorite colors are blue and pink.She is a member of the Heartfilia family, once one of the wealthiest and most influential conglomerate families in the country of Fiore.However, due to her estranged relationship with her father and the death of her mother, Layla Heartfilia, she left home to follow her own path, which displays an ambition for independence.
Lucy is very kind to her Celestial Spirits, and refuses to utilize them as shields or think of them as such. She fights alongside her Spirits and treats them as friends, unlike several other Celestial Spirit Mages, who view them as mere tools and objects.Lucy cares greatly for her Spirits and will also go to great lengths to give them happiness, even at the cost of her life. Despite technically being an owner of the Spirits, she refuses to be addressed as such, and instead prefers to be called their friend.Although, Lucy is, in most cases, cowardly and easily frightened, she has no problems with fighting and would happily stand up to danger, even if she ends up getting hurt, for her friends and guild. While her powers are normally not as overwhelming as her teammates, Lucy has proven to be a capable combatant herself, often using her cleverness to her advantage, and thinking outside the box during battle. She has eventually inherited Natsu's stubbornness and refusal to give up, even when the odds are against her.
Lucy usually freaks out at her guildmate's antics. Unlike most of her friends, she does not get very excited about fighting and is not quick to resort to violence as the solution. However, she does admit that being around her guildmates is really fun. Being a Celestial Mage, Lucy always keeps her promises. She gives her all for the sake of her guild and friends.
