"What's more important?! Memories?! Keys?! Feelings of guilt?! I don't think so! It's the power to save your friends! The power as a Celestial Spirit Wizard!"

Media of Origin:
Aquarius is a character from the anime series, Fairy Tail. Her key was owned by Lucy Heartfilia until she sacrificed it in order to summon the Celestial Spirit King. She is also Scorpio's girlfriend.
Why She Sucks
She is mostly a bitch to Lucy and always abandoning her at the eleventh hour, despite Lucy being her former master's daughter, to whom she promised to protect.
Her attitude towards Lucy is largely because she would frequently summon her because she didn't have any friends in the past, and always viewed her as a crybaby even long after she grew out of it.
Despite being one of Lucy's trusted spirit companions, she deeply resents her. In fact, not only does she have no trouble attacking Lucy, but she even abandons her for a date with Scorpio at times when she's most needed.
During the Tartaros arc, When Lucy's life is in clear danger without any of her guild-mates to help her, the worst she does to Lucy is call her an idiot for overexerting her magic power to summon her.
The main reason she's always upset with Lucy is because she is stuck in a Heroic BSoD over Layla's death and felt her daughter could never hold a candle to her. Sadly, this does not justify her behaviour, especially the way she acts, not even showing any signs of mental trauma.
Later, right before Lucy breaks her key, Aquarius claims she always hated Lucy for being such a naive, crybaby little brat and even tells her she'd be relieved if they never saw each other again.
Despite her harsh treatment towards Lucy, she does care for her at times and refuses to leave her side along with the other spirits.
Aquarius' design is beautiful, fitting her appearance with the Zodiac sign.
Her Japanese and English voice actresses do a good job voicing her.
She has a good relationship with Juvia, signaling a friendship between them.
She at least admits she feels guilty towards something she did to Lucy even though she had no memory of what happened during the Eclipse Celestial Spirit arc.
She saved Lucy right before Brandish can kill her and showed them the interactions between Layla and Grammi, Brandish's mother, along with a memory revealing that Zoldeo killing Grammi, making Brandish realize that Lucy was not at fault.
