Scorpio

Scorpio (スコピーオン Sukōpion), "The Scorpion" (天蠍宮 Tenkatsukyū), is a Celestial Spirit that is one of the 12 Golden Zodiac Keys. He is Aquarius' boyfriend. His key is currently owned by Lucy Heartfilia.

Appearance
Scorpio is a relatively tall, lean-built, dark-skinned man with short hair that is red on one side and white on the other. His tail is a large gun that is shaped like a scorpion's tail that has the word "Antares" written on it. He wears no shirt, but has a flower shaped collar that is red and trimmed with gold around his neck. He has a red sheet-like material around his waist that is kept up by his large belt that has the Scorpio symbol on it. He wears black shorts, and has bandage-like material wrapped around his arms and legs.

Scorpio has a habit of folding his middle and ring fingers back while keeping his index and little fingers extended, mimicking the pincer claws of a scorpion.

During the fight of Lucy against Flare Corona, Scorpio appeared with a different outfit. He now wears a pea coat with armbands, and a dark undershirt. His tail is fixated with a belt with two buttons.

Personality
In contrast to his girlfriend Aquarius, Scorpio is much kinder, and much more respectful to Lucy. Scorpio has a strange manner of speaking, he says "We are" in the beginning of each sentence and refers to his sand as "our sand". He is also a trustworthy spirit.

Magic and Abilities
Sand Magic (砂魔法 Suna Mahō): In relation to his scorpion theme, Scorpio is known for employing Sand Magic as his primary means of combat. He is shown casting such Magic through the use of his scorpion-like stinger, using it to produce sand which is focused to assault opponents at mid-to-long range. Scorpio is shown to be able to shape large amounts of sand in various ways, such as a tornado or beam.
 * Sand Buster (サンドバスタ─ Sando Basutā): Once summoned, Scorpio gets down on his four limbs, in a stance which is reminiscent of a real scorpion's, and then points his scorpion-like stinger at the opponents. A large amount of sand is subsequently fired from it in the form of a powerful sand tornado which moves towards the target in a line and strikes them with great blunt power; so much, in fact, that even nearby enemies which aren't directly struck by the attack will be thrown to the ground by the tornado's sheer rotatory power. Aside from its most obvious, offensive use, Sand Buster was shown being used in another way, with Lucy having Scorpio combine it with Wendy Marvell's Sky Dragon's Roar through Unison Raid in order to boost Natsu's speed, allowing him to strike Hades.


 * Sand Spear: Scorpio fires from his scorpion-like stinger a thin but powerful piercing beam of sand at the enemy.


 * Sandstorm Axe Aldebaran (砂塵斧アルデバラン Sajinbu Arudebaran): A combo attack used alongside Taurus, Scorpio attacks with Sand Buster, then Taurus uses his axe to control it and send it to attack the opponent.


 * Sand Wall (砂の防壁, サンドウォール Sando Wōru): Scorpio summons forth a large amount of sand to protect him from incoming attacks, which is enough to guard from Kamika's lightning attacks.

Immortality: As a Celestial Spirit, Scorpio cannot die, unless he is somehow forced to stay in the Human World for too long without returning to the Celestial Spirit World, something which would slowly kill him.

Fairy Academy - Yankee-kun and Yankee-chan!
Scorpio assumes the role of a teacher in Fairy Academy while eating lunch with fellow school staff and his girlfriend Aquarius, the swimming instructor. He and the other Celestial Spirits make up the school staff.

Fairy Tail Gekitotsu! Kardia Daiseidou

Trivia

 * The word "Antares" is written on his tail. Antares (Alpha Scorpii) is the brightest star in the constellation Scorpio and the 16th brightest star in the night sky. However, it is noticeably missing in the anime and was only shown in the manga.
