Celestial Spirit User: Lucy practices Celestial Spirit magic, a skill which allows her to summon Spirits from another world or the Celestial World using Keys of the Gates. Her Celestial Spirits have varying levels of power, with different ones suited for different tasks. For example, Aquarius can control water, while Taurus has enormous strength. Lucy explains to Natsu that Celestial Spirit mages have the potential to obtain extremely rare Gold Keys, which open the gates of the "Ecliptic Zodiac", and common, store-bought Silver Keys. Each Gold Key has the Zodiac symbol of the one it is used to summon on it. According to Lucy, while there are large number of Silver Keys, there are only 12 Gold Keys. Thus far in the series, Lucy has obtained 10 Gold Keys and 4 Silver Keys. Lucy's ability to summon her Spirits is limited by how much magic she has to sustain them; if she summons more Spirits, more of her magic is exhausted. She has demonstrated so far that she is able to use five of her Ecliptic Zodiac Keys in one day (as seen in the S-Class Wizard Trial arc where she summons Virgo, Aquarius, Taurus, Sagittarius and Scorpio) so far.
Force Gate Closure: When Lucy was fighting with Sherry in Galuna Island arc, she has gained the ability to shut the Gate of the spirit, who recalled, by force. This is an extraordinary ability because usually closing or opening the Gate is done by mutual consent of the Mage and the Spirit. Also, some of her spirits can pass their gates without being called if she is in danger or out of magic power.
Multiple Summons: Lucy also has the unique ability to summon more than one Celestial Spirit, summoning all of her Gold Keys (5 of them at the time) and one of her Silver Keys (Nikora) at once. In the anime, she summoned all the Spirits she had, including all 4 of her Silver Keys. Although it only lasted a few seconds. Even Karen Lilica, Leo's previous owner and a powerful Celestial Spirit mage, was unable to summon more than one Spirit.
