Aries (Ares)

Ares is an S-Class Mage of the Fairy Tail Guild, wherein she is a member of Team Natsu. It is eventually revealed that she is the celestial spirit Aries (アリエス Ariesu), known as "The White Lamb" (白羊宮 Hakuyōkyū).

Personality
Ares is energetic, cheerful and slightly on the rough side as she's fond of tackling others and quick to fight back against a possible kidnapper. Ever since she was little, Ares has had a romanticized view of the Mage profession. She is quick to reveal she wanted to become a Mage in order to be like the great heroes in fairy tales, and she has described being one as far more "romantic" than being a police officer. Her mentality is described as "I don't have time for my emotions. I've gotta make sure that everybody else is okay." She has also shown a distinct lack of ability picking up social cues due to being a very open and honest person.

She has shown a close connection with Gray Fullbuster, as they are childhood friends. When Meredy threatened him, Ares loses her calm demeanor and entered a somewhat satanic-appearing state that frightens Meredy and even Erza. She's also very polite towards other, typically addressing others with honorifics, though she addresses Gray as "Gray" only.

Although Ares has no trouble interacting with her friends, she does have trouble actually making them, and once admits that seeing new types of magic "is like meeting new people, but better".

She cares deeply for Fairy Tail and its members. During the Battle of Fairy Tail arc, Ares is pitted against Cana Alberona but instead chooses to sacrifice herself by attacking a thunder Lacrima, even though she knows that it will cause her harm. She is also shy about her body, as she doesn't like to shower with other girls. By X792, having spent a long time living with Gray, she also appears to have affectionately adopted or picked up Gray's habit of shedding clothes spontaneously.

During episode 6 of the anime, it is revealed that Ares has had a fear of large crowds, as shown when she freezes up when she saw the large crowd forming at the train station. Then it comes back again when she was forced to distract Erigor. However, she manages to work through that fear with some encouragement from her teammates long enough to distract him.

In combat or dangerous situations, she is shown to be quite impulsive and battle eager. This trait contrasts with her adaptability, for she is quite capable of forming attack plans with others in order to take down stronger foes. She embraces battle more easily than others, possibly treating it like a game.

Ares has been shown to be ruthless at times when it comes to protecting her loved ones. This is most likely a side effect of the traumas she experienced.

When under the influence of the Root of Calamity, her personality briefly changes significantly. She begins talking in a much lower voice, and makes an active attempt to kill the target of her anger, often screaming loudly in the process.

Ares

 * "As a girl, I wanted to be just like those heroes in the books... Someone who fought for what was right, and protected people who couldn't protect themselves!"
 * "What the-?! I don't need to 'break out of my shell'! That's absolutely-"
 * "You've got a team now. We both do. And if we fail, then, we'll just be bringing them down with us. We have to put our teammates first, and ourselves second. Our team deserves a great leader. And I think that can be you."
 * "We've never backed down before, and we're not going to start now."
 * (Ares visits her mother's grave) "Hey, mom. Sorry I haven't come by in a while."
 * (Ares remarks that she is following in her mother's footsteps) "I guess it's like they say: "like mother, like daughter"!"
 * (Ares bids farewell to her mother) "Wish me luck... It was good to talk."
 * (Ares exclaiming about her new hoodie) "It's got a cute little bunny rabbit!"
 * "No! But I won't stand by and watch someone get hurt!"
 * "This is my fight, too!"
 * (Ares to her Uncle) "I'm willing to do whatever I can to help because I trust you. But why couldn't you trust me?"
 * "You told me once that bad things just happen. You were angry when you said it, and I didn't want to listen. But you were right. Bad things do happen, all the time, every day. Which is why I'm out here, to do whatever I can, wherever I can, and hopefully do some good."
 * "We've all lost something, and I've seen what loss can do to people. But if we gave up every time we lost, then we'd never be able to move forward."
 * "You're wrong. We've done things that most people would call impossible, and I know the only reason we were able to do it is because we didn't do it alone! We had people to teach us, people to help us, we had each other. Work with us. At least I know we'll have a better chance if we try together. Please."
 * "That's all that matters. That we're all here together."
 * (Root of Calamity; 1) "No...!...STOOOOOOP!"
 * (Root of Calamity; 2) "Wa......aaaAAA! STOOOP ALREADY!"
 * "You!"

About Ares

 * "She's always wanted to be a Mage. It's like she said, ever since she was a kid, she'd dream't about being the heroes in the books. Helping people and saving the day, and never asking for anything else in return. Even when she couldn't fight, she knew that's what she wanted to do. That's why she trained so hard to get where she is today." —Gray Fullbuster
 * "I remember getting to know Ares and thinking, "This girl is the embodiment of purity." — Erza Scarlet
 * "In some ways, yes. But in many others, no. She has her quirks, her faults, just like everyone else. But she also possesses something unquantifiable- a spark that can inspire others even in the darkest of times." —Makarov Dreyar, answering if she was one of the best mages in Fairy Tail.
 * "If there's one thing I know about her, it's that she somehow always knows the right thing to do." — Gray Fullbuster

Trivia

 * It is confirmed that Ares is left-handed. However, she is seen wielding a weapon with her right hand just as easily, implying trained ambidexterity. Ares has stated that it is "common to switch both hands while fighting, especially to make it interesting." Later, Ares is seen writing a letter with her right hand.
 * Although Ares is often depicted to favor sweets like cookies, her favorite food is actually strawberries.
