Personality 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 guild mate'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 guild mates is really fun. Being a Celestial Mage, Lucy always keeps her promises. She gives her all for the sake of her guild and friends.
Magic
Lucy practices Celestial Spirit Magic, a type of Spatial Magic which allows her to summon Celestial Spirits, magical beings residing in the Celestial Spirit World, using the Keys of their respective Gates. When summoning a Spirit, the Keys are enveloped with a soft, golden light. Once a contract has been made with a Spirit, such Spirit will be available for Lucy to summon on certain days, in which it will fight on her side and perform several tasks for her. Her Celestial Spirits have varying levels of power, with different ones being more suited for certain tasks than others, not necessarily related to battle.
For example, Aquarius can manipulate water, creating powerful waves which can sweep away large amounts of foes at once, while Taurus has enormous physical strength, making him a valuable melee fighter, able to flank Lucy during battle and tackle opponents on her behalf. However, Celestial Spirits are sentient beings who possess personalities and traits, and are thus able to act accordingly during battle, sometimes even ignoring Lucy's orders and acting on their own.
Celestial Spirit Mages have the potential to obtain extremely rare Gold Keys, which open the gates of the "Ecliptic Zodiacs", and more common, store-bought Silver Keys. There are a large number of Silver Keys, but there are only 12 Gold Keys, each of them being related to a specific astrological sign. So far, Lucy has obtained 10 Gold Keys and 5 Silver Keys, a considerable amount of Keys for a single Celestial Spirit Mage. Lucy's ability to summon her Spirits is limited by how much Magic Power she has to sustain them; the more Spirits she summons and the more powerful they are, the more Magic Power she exhausts. She is capable of using five of her Ecliptic Zodiac Keys in one day, a noteworthy feat, and she has also demonstrated the ability to summon Celestial Spirits by simply calling on them instead of using their keys.
Force Gate Closure: Lucy is able to force the gate of a Celestial Spirit to close against their will, prompting them to return to the Celestial Spirit World. She demonstrated this ability when Taurus was taken over by Sherry Blendy through her Magic and was forced to attack Lucy. For a Celestial Spirit Mage, obtaining this ability seems to be a remarkable feat. When using this ability, it is possible that once a spirit has been absorbed by someone, the absorber may go to the Celestial Spirit World as well.
Multiple Summons: Lucy has gained the advanced ability to summon more than one Celestial Spirit at once: she has been even shown summoning all of her Gold Keys (5 of them at the time) and one of her Silver Keys (Nikora) at once, something which greatly astonished Loke; however, due to the large amount of Magic Power required for such feat, she was able to keep it active for just a handful of seconds. After gaining access to her Second Origin, Lucy gains a greater control over this ability, as seen during her fight with Flare when she was able to keep two Celestial Spirits' gates open nearly effortlessly. This provides her greater flexibility as she is able to combine the aspects of her Spirits' powers and abilities to form new and more powerful attacks. She can also use her own Magic in combination with another Spirit to increase the power of an attack. During her fight against Tartaros, Lucy managed to open three gates simultaneously, something which has been referred to as a forbidden technique.
Recompense Summoning: A technique that only a Celestial Spirit Mage possessing enough Magic Power to open three or more Golden Zodiac gates simultaneously is able to carry out, in order to summon the Celestial Spirit King, the strongest among the Spirits, once. In order to save her friends, Lucy sacrificed Aquarius's key as the sacrifice needed to be of a Spirit she has strong mutual trust with. By doing so, Lucy was able to summon the Spirit King and destroy Plutogrim.
Star Dress: A Celestial Spirit Magic spell in which Lucy incorporates the power of the Celestial Spirit she summons into her body, which manifests itself in the form of a dress and a tattoo of the Spirit's zodiac sign on her body. While using this spell to each of her Spirit's forms, Lucy's own Magic power has been increased further allowing her to make use of stronger spells that takes so much Magic power required to use when in combination to her spirits power.
Aquarius Form: This form was bestowed upon her by the Celestial Spirit King, and once in it, Lucy took on an appearance based on Aquarius' own, having acquired a bikini top that sports a zigzag design and a miniskirt. Aquarius' zodiac sign is located between Lucy's collarbone whilst in this state. The tattoo fades away as Lucy collapses after successfully casting Urano Metria and defeating Jackal, however she was later seen with the tattoo once more.(Unnamed) Water Magic: After sacrificing Aquarius' key to summon the Celestial Spirit King, Lucy was bestowed the Magic of Aquarius by the Celestial Spirit King, which allowed her to both consciously and unconsciously make use of her friend's powers. Water Barrier: Lucy generates a powerful barrier of water, capable of blocking even the explosions generated by Jackal's powerful Curse. (Unnamed)
Leo Form: By incorporating the power of Loke into her body, Lucy becomes cloaked in an elegant, frilled, black ball gown that is slit up her left leg and tied with gold sash that sits around her hips. A black, frilled choker sits around her neck, and a ribbon with the mark of the Leo zodiac emblazoned upon it falls between her breasts. The accompanying sleeves of the dress are detached, sitting on Lucy's upper arm and falling to her forearm, where they flare outward. Around the bodice of her dress is more golden trim, curving inward under her bust. Additionally, Lucy sports black heels and her hair is now tied up in a quaint bun that is decorated with a black flower. Due to having taken on some of Loke's power, Loke's zodiac sign appears upon Lucy's right breast. Regulus: Due to having taken on some of Loke's power, Lucy becomes able to use Regulus in a manner similar to Loke: imbibing parts of her body to do enhanced melee damage. Regulus Lucy Kick: A variation of her signature Lucy Kick attack, after surrounding her feet with the light of Regulus, Lucy kicks her target; the light enhances the strength of the kick.
Virgo Form: Lucy incorporates the power of Virgo into her body, which grants her a dress very similar to Virgo's own, however due to its lacking the entire shoulder and most of the upper arms, the apron is now a pattern on the front of the dress; Lucy also receives a more frilly version of Virgo's headpiece, and still has Virgo's collar, albeit with the strings that are on Virgo's headpiece tied in a bow knot around it. She also bare Virgo's Zodiac sign on her right shoulder. Earth Magic: While in this form, Lucy gains access to Virgo's Earth Magic. Diver: Lucy, now with the powers of Virgo, has the ability to use Diver and tunnel through the earth.
Taurus Form: Lucy incorporates the power of Taurus into her body, which grants her an outfit consisting of a bra and sleeves with a cow pattern and pants that leave her right leg entirely revealed. She also dons a pair of gloves and boots as well as a belt where Taurus Zodiac sign is located and a bag around her waist. While sporting this dress she uses her hair in two buns, one at each side of her head abut also leaving some hair hanging. Lucy also carries her whip with her in this form. Immense Strength: This form grants Lucy the grand strength of Taurus, allowing her to pull a target with her whip while striking everything it touches, including other targets and even destroying the ground without any fatigue. This also enhances the sheer physical strength of Lucy's melee combat enough to either incapacitate her targets, or send them flying. Earth Wave: Lucy strikes the ground with her whip, causing it to rupture the earth in the area in front of her, damaging anyone above it. Lucy Punch: Lucy briefly empowers her fist and subsequently lunges at her target, punching them with great strength.

A pair of dark thigh-high boots with light trim at the top, which split above the knees to reveal the front of the thighs, are also donned. The hair is styled into a typical ponytail with two bangs framing the face. In addition, Sagittarius's zodiac sign is located on the left shoulder. Marksmanship Specialist: This form grants Lucy the excellent marksmanship of Sagittarius, allowing her to fire several arrows simultaneously with each arrow hitting its mark. Arrow Summon: Lucy is able to summon multiple energy arrows just by using her bow. Star Shot: Lucy is able to fire a series of homing arrows which explode upon contact with their targets.
Aries Form: Lucy incorporates the power of Aries into her body, which she is granted an outfit consisting of a two-toned, short woolen hoop dress that ends at Lucy's mid-thigh level. The dress leaves her shoulders and arms bare, however, her arms are covered by woolen arm warmers and a woolen scarf is wrapped around her neck. Her legs are covered by horizontally striped leggings.
