Pisces

Pisces (ピスケス Pisukesu) is a Celestial Spirit that is one of the 12 Golden Zodiac Keys. Their key is currently owned by Yukino Aguria.

Appearance
Pisces appears as two separate entities, being huge sea creatures which resemble fish, but also show elongated bodies similar to those of eels. All in all, their appearance is vaguely reminiscent of koi fish. The two of them appear from an ethereal vortex generated behind the one employing their key. Both share similar traits, possessing large and wide open round eyes with dark pupils sitting at their heads' sides and massive mouthes with light thick lips full of squared teeth. A number of fins are also present on their bodies, with a series of long, jagged ones crossing the whole length of their upper part, almost reaching up to top their heads, and a smaller, more squared being located on the ends of their faces, one on each side. Their bodies are also covered in lines crossing their whole length, with each line being flanked by a row of spots; more spots form a single, hinted semicircle above each eye. What distinguishes the two fish is the color: the one to the right from the portal is light and sports dark markings; the other one, on the contrary, has light markings covering its dark body. Both creatures bear the symbol associated with the constellation of Pisces on their forehead, respectively dark and light in color.

Grand Magic Games arc
During the Grand Magic Games, Pisces was summoned by Yukino during her fight with Kagura Mikazuchi and was easily defeated alongside Libra by the latter.

Magic and Abilities
Flight: Pisces can glide through their air and attack their opponents from above. Their main form of offense seems to consists of throwing themselves against the target at high speed, using their massive heads to inflict powerful blows. Such a rudimentary attack possess enough force to lift large amounts of sand in the air, when the fishes' strikes connect with a sandy surface. The two separate beings are capable of synchronizing their assaults, moving in unison.

Immortality: As a Celestial Spirit, Pisces cannot die, unless they are forced to stay in the Human World for a long period of time.
