Aquarius

Aquarius "The Water Bearer" is a Celestial Spirit that is one of the 12 Golden Zodiac Keys. Her key is currently owned by Lucy Heartfilia.

Appearance
Aquarius is a mermaid-like Celestial Spirit. She has a long blue tail, large breasts and she wears a revealing bikini top. She has two gold armlets and she wears a jewel circlet. She wields an urn which is the basis of her powers.

Personality
Aquarius is very moody and ill tempered woman, who often threatens to kill her owner, Lucy. Despite this, she does care for Lucy's safety. Demonstrated when Hughes threw Aquarius' water attack back at her and Lucy, she screamed for Lucy to get down. She is very kind and loving towards her boyfriend, Scorpio, to which she shows a completely different side of herself. She also goes as far as to threaten Lucy to keep quiet about her moodiness in front of Scorpio unless she wants to be a "drowned corpse".

History
Aquarius's previous master had been Lucy's mother, Layla Heartfilia. When Layla retired from her work as a Mage, she entrusted the key to another Mage with instructions to present the Aquarius's key to Lucy should Lucy decide to become a Mage.

She doesn't pick on her usual victim, Lucy however, and instead chooses to bicker with Cana after wards, saying all women are her enemies, just being 'firm and bouncy' doesn't count as 'justice'. Aquarius also gives Cana 0 points as a woman, and this argument shows Lucy how similar Cana and Aquarius are. It was revealed that once she belonged to Layla Heartfilia, Lucy's mother.
