Artemis

Artemis (Άρτεμις in Ancient Greek) is the goddess of the Moon and the Hunt. Her Roman counterpart is Diana. She and Apollo are known as the "twin archers."

History
She was born on the remote island of Delos. Her mother Leto had been running from Hera because she was angered about Zeus's affairs. Hera forbade her to give birth on terra firma (earth) or on an island. But the island of Delos was neither on the ground or on water; it was a floating island, so Leto gave birth there. She was born before her brother Apollo and helped her mother give birth to him. That is why she is sometimes considered the goddess of child birth. Artemis and Apollo were born as twins to Leto and Zeus. They grew up together.

At three years old, Artemis asked her father, Zeus, while sitting on his knee, to grant her six wishes. He loved his little daughter, and was very proud of her. She was his second daughter, and a bright and pretty child, and he agreed to grant her her wishes.

Her first wish was to remain chaste for eternity, and never to be confined by marriage. She then asked for lop-eared hounds, stags to lead her chariot, and nymphs to be her hunting companions, 60 from the river and 20 from the ocean.

Also, she asked for a silver bow like her brother Apollo's golden one. He granted her the six wishes, also said that he promised to let her retract her wish to remain a virgin if she should wish it.

Once Artemis grew close to retracting her virgin oath, when she met the hunter Orion. They slowly grew close, until Apollo, protective of his sister's virginity, had him swim out to sea to retrieve a floating target. Then, he tricked Artemis to shoot a distant, moving target, knowing his sister couldn't resist such a challenge. She did, and by this trick killed Orion, as the target was his head. In grief, she made him a constalation in the stars to always see his face.

The Titan's Curse
Artemis makes her first appearance in the The Titan's Curse. She helps Percy and friends when they face the manticore at Westover Hall and goes a mission west to hunt the Ophiotaurus, and promises Percy that she will look for Annabeth. She is captured along the way by the General, Atlas, and is used as a way to lure Percy and his friends West to save Annabeth. Atlas traps Artemis under the sky by forcing Annabeth to hold it. Artemis cannot simply stand by and allow a maiden to die, and she takes the sky from Annabeth.

Percy, Thalia, and Zoë rescue her, Zoe giving her life to stop Atlas from stabbing Artemis. Artemis, Percy, Thalia and Annabeth return to Olympus for the winter solstice. She is the first to suggest plans for war preparations against the Titans, and appears fair and honest, as she is horrified at the vote whether or not to destroy Percy, as he risked his life for them.

The Last Olympian
Artemis appears again in The Last Olympian, when she battles Typhon. Her Hunters help the Campers fight against Kronos' army.

Physical description
She can appear as whatever she likes, but chooses to be the average age of her Hunters, which is around twelve. She has auburn colored hair and eyes as silvery as the moon, and is incredibly beautiful. Her cabin is number eight at Camp Half-Blood and since she is a maiden goddess, she has no children and it serves an honorary monument or a refuge for the Hunters when they visit. Her symbol was the silver bow and arrow, and stag.

Personality
Artemis cares deeply for maidens, as they are her kin. She has a group of female Hunters who she leads. She mostly detests men, and has little respect or liking of them. She is always at odds with her brother Apollo, as he always tends to flirt with her Hunters. Despite this, there is great loyalty between the two siblings. Artemis is an excellent hunter, and does not have pity on her prey, or even her own Hunters if they fall in love and break their oath. Though she holds a deep prejudice against men, she is typically reasonable and willing to acknowledge them if they prove their worth, as she does with Percy.

Powers
As the goddess of the hunt, Artemis probably possesses advanced hunting abilities such as speed, precision and the ability to disguise herself along with many other powers. She can also transform things into things associated with hunting ( eg. once she turned a helicopter into a flock of birds).

She may also have some sort of unknown moon related abilities since she is godess of the moon.

And she can change her age appearance but all gods might be able to do this

Artemis presumably possesses the standard powers of a God.

Film
Artemis was played by Ona Grauer in the film version of The Lightning Thief.

She was only seen once in the film, in the throne room of Olympus on the summer solstice.
