The key is a golden Celestial Spirit Key, with the bow of the key containing a white center, bearing the crest of the Scorpion, colored in dark red. The part above the crest represents a scorpion's tail and needle. The blade of the key is forked at the end, similar to a scorpion's claw.
While in possession of the key, a Celestial Spirit Mage may be able to summon the Scorpion Scorpio by reciting the quote, "Open the Gate of the Scorpion! Scorpio!". This summons Scorpio, a man with a stinger-shaped gun that can be used to attack with Sand Magic.
