Sagittarius

Sagittarius, The Archer, is a Celestial Spirit who wears a horse costume that is currently owned by Lucy Heartfilia.

Appearance
Sagittarius, despite how people would usually view him, is a tall, black-haired lanky man wearing a horse costume. He has rustic, almost medieval clothing. He carries a giant bow and has a giant quiver on his back.

Personality
Sagittarius is very formal and respectful to his owner. He carries out his orders quickly, and always tries to do what is in his capabilities. He also seems to take all of his requests literally, leading him to misinterpret certain orders such as Lucy's request to create fire (initially believing it to be a request to make fire from nothing rather than set something aflame). He has a habit of uttering the phrase "moshi moshi", which literally means "hello" in Japanese.

Galuna Island arc
Sagittarius's Gate key is offered by the people of Galuna Island along with a 7 million Jewel reward for anyone who would be able to lift the curse caused by Team Lyon's Moon Drip ceremony. Team Natsu of Fairy Tail completes this job, but are forced to turn down the Jewel reward since they had acted without official permission from their guild's master or S-Class Mages. At Lucy's insistence, however, the team accepts Sagittarius's Gate key as a gift of appreciation from the islanders.

Phantom Lord arc
While being kidnapped by Phantom Lord, Lucy accidentally drops all of her Gate keys except for Sagittarius's. He is later summoned by Lucy for the first time in a desperate effort to create fire for Natsu to eat and help him fight Gajeel. Sagittarius says he cannot, misinterpreting Lucy's order as a request to make fire himself, which he is unable to do. Upon hearing Happy bemoan the lack of fire in general, however, Sagittarius realizes that they only wish to set something aflame, which he does by shooting at a set of machinery with his arrows and causing a fiery explosion, thus allowing Natsu to regain his energy and defeat Gajeel.

Fighting Festival arc
Lucy summons Sagittarius during her fight against Bickslow to shoot down all of Bickslow's dolls. He accomplishes the order, but fails to destroy the souls implanted inside the dolls. Bickslow is thus able to create more dolls, which attack and defeat Sagittarius.

Oración Seis arc
Sagittarius is one of the spirits Lucy summons to fight the Naked Mummy guild, who have taken the Love & Lucky guild hostage.

He is summoned again when Lucy sees Gray trying to kill Natsu. "Gray" is revealed to be Gemini in disguise and transforms into Lucy, taking advantage of Hibiki's weakness for women by flashing their breasts, shocking even Sagittarius. While disguised as Lucy, Gemini commands Sagittarius to shoot Hibiki in the back with his arrows, which he does against his will. Lucy forces his gate closed, but Gemini summons him to their side using a copy of his Gate key, leaving Lucy unable to control him. Gemini orders the unwilling Sagittarius to shoot down Carla as she escapes with Wendy Marvell, but Gemini's owner Angel appears and commands them to stop. Gemini reverts to their true form, closing Sagittarius's gate.

Daphne arc (Anime Only)
Note: Events in this arc occur only in the anime and do not constitute canon material.

Lucy summons Sagittarius and has Erza, Bisca, Alzack, Levy, Macao, and Reedus cast fire magic on Sagittarius's arrow, which he fires towards Natsu for him to eat and help him fight Daphne.

Tenrou Island arc
Sagittarius is summoned by Lucy to fight off Kain Hikaru while he chases her on Tenrou Island. He fires arrows at Kain's legs, but Kain kicks them back at him and defeats him.

X791 arc
Sagittarius celebrates Lucy and her friend's return from Tenrou Island when Virgo brings them to the Celestial Spirit World. After the celebration, Sagittarius sees Lucy and her friends off with the rest of Lucy's Celestial Spirits.

Magic and Abilities
Master Archer: Sagittarius, living up to the theme of his costellation, employs bow and arrows in battle, with his skills as a Celestial Spirit lying in their use. He has proven himself to be an extremely proficient archer: he was shown capable of easily destroying Bickslow's dolls, small objects which manoeuvre at high speed in midair, with his arrows, demonstrating both pinpoint accuracy and great speed. He is capable of nocking and firing more than one arrow at the same time, being shown firing a barrage of them at Kain Hikaru. He also seems to be very resourceful with his archery, as shown when he was able to create fire by shooting electrical equipment so that Natsu Dragneel could replenish his strength; a feat which he claimed to be "mere child's play" for his arrows.

Immortality: As a Celestial Spirit, Sagittarius cannot die, unless he is somehow forced to stay in the Human World for too long without returning to the Celestial Spirit World once; something which would slowly deplete his life force, eventually resulting in his death.

Equipment
Bow and Arrows: As evident of his role as an archer, Sagittarius is always shown carrying around a bow and a quiver full of arrows. The bow is quite small if compared to its tall owner, and, strangely enough, seems to be composed of metal. Connected to the central part, the handle, which is covered in leather strips, are the two limbs, which grow larger near their center, and then grow smaller again near the edges, to which the string is tied. Such bow is used to fire the large arrows resting in the massive, cylindrical quiver attached to Sagittariu's back via a large buckled belt, passing over his right shoulder and crossing his chest diagonally. These arrows possess massive, light fletchings and simple metal heads. While shown wielding the bow with his right hand when first summoned by Lucy, Sagittarius always adopts the standard stance of a right-handed archer, wielding the bow with his left hand and aiming the arrow with the right one.

Fairy Academy - Yankee-kun and Yankee-chan!
Sagittarius appears as a teacher in Fairy Academy while training for an archery competition. He is talked about as the pride of the academy who has won many awards for archery. Sagittarius and other Celestial Spirits make up the school staff.

Trivia

 * In the English version, Sagittarius's greeting,"Hello, Hello", is retained in its Japanese form, "Moshi, Moshi".
 * When Natsu thinks about Sagittarius' appearance, the flower creature resembles Nakajima from Mashima's last work Rave Master.
 * Lucy, Gray, and Natsu all were partially right about Sagittarius' appearance/personality. Gray got the overall form correct, Lucy correctly predicted his main weapon; a bow, and Natsu envisioned him saluting (Despite the fact that the rest of Natsu's version wasn't even close).
