Appearance

After saving Galuna Island from the Moon Drip, Erza receives Sagittarius as a reward and it is given to Lucy.

Phantom Lord arc
Lucy Summons Sagittarius during Natsu's fight against Gajeel Redfox. Much to Lucy's surprise, Sagittarius resembles Gray's description. Lucy commands Sagittarius to try and make fire for Natsu to eat so the battle will be even but Sagittarius says that he can't. Soon, however, Sagittarius figures out that Lucy wanted him to find a way to obtain fire, not make it himself. He shoots some nearby machinery and sets it aflame for Natsu to eat.

Fighting Festival arc
Lucy summons Sagittarius during the fight against Bickslow. He shot down all Bickslow's dolls, but he is soon defeated, because it turns out that Bickslow has manipulates souls and not the bodies of the dolls himself, meaning he can transfer those souls into other dolls' bodies and attack again.

Oración Seis arc
Lucy summons Sagittarius again to stop "Gray" from attacking Natsu. However. "Gray" suddenly attacks Lucy who is protected by Hibiki Laytis. Hibiki's says that "Gray" isn't the real Gray but Gemini. Gemini takes advantage of Hibiki's weakness of women by transforming into Lucy and removing her top, shocking Lucy, Hibiki, and Sagittarius. Gemini, in Lucy's form, commands Sagittarius to attack Hibiki and Sagittarius does so, shooting him in the back with one of his arrows. Lucy force closes his gate, but Gemini summons him again and orders him to shoot down Charle who's escaping with Wendy Marvell. Lucy tries to force close the gate again but since Gemini summoned him, she can't force his gate to close. Angel walks in and tells Gemini to stop and Gemini reverts to their original form, forcibly closing Sagittarius' gate.

Daphne arc (Anime Only)

Lucy summons Sagittarius, and then tells anyone in Fairy Tail to use Fire Magic on Sagittarius's arrow, so he can send it to Natsu. Erza Scarlet, Bisca Mulan, Alzack Connell, Levy McGarden, Macao Conbolt and Reedus Jonah all use attacks, and it is then sent to Natsu, who eats the fire.

S-Class Trial arc
Sagittarius is summoned by Lucy to combat Kain Hikaru but when he shoots arrows at Kain, Kain kicks them back at him and defeats him.

Magic and Abilities
Archery: Sagittarius' weapon of choice is a bow and arrow. He was able to easily crush Bickslow's toys with his arrows, going right through the dolls without stopping. He also seems to be very resourceful as he was able to create fire by shooting electrical equipment so Natsu could replenish himself.

Immortality: As a Celestial Spirit, Sagittarius cannot die, unless he is forced to stay in the Human World somehow.

Trivia

 * Sagittarius seems to have the habit of saying "Hello, hello" after anything he says.
 * In the English version, however, it retained the original "Moshi Moshi" greeting from the Japanese version.
 * 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).
