Aquarius
"The Water Bearer" is a Celestial Spirit that is one of the 12 Golden Zodiac Keys. Aquarius is a moody and ill-tempered Celestial Spirit who often threatens to kill her owner, [Lucy](https://anilist.co/character/5186). When summoned, Aquarius will either attack the opponent, Lucy, or both of them, depending on her mood. Despite this, Aquarius does care for Lucy's well-being, which will later be elaborated on. Aquarius' previous master had been Lucy's mother, [Layla Heartfilia](https://anilist.co/character/37965). When Layla retired from her work as a Mage because of her health problems, she entrusted Aquarius' Key to another Mage with instructions to present it to Lucy if she chose to be a Celestial Spirit Mage. Aquarius' key was the first key that Lucy ever received. Because there weren't any other children to play with, Lucy would summon Aquarius as a playmate. This greatly infuriated Aquarius, however, learning why Lucy summoned her, the Celestial Spirit couldn't help but feel bad for the girl. The boyfriend she mentioned in episode 1 is actually [Scorpio](https://anilist.co/character/33522), another stellar spirit as well. Her key was owned by Lucy Heartfilia until she sacrificed it in order to summon the [Celestial Spirit King](https://anilist.co/character/33516). Nevertheless, Lucy still owns a part of her original key.
