Leviathan is a summon from Final Fantasy XI, being one of the six celestial Avatars, representing the water element. Leviathan was made available as an unlockable summon spell for Summoners during the Rise of the Zilart expansion.
Leviathan was a great sea serpent who used to terrorize the Gugru Sea, in protest of the development of sea commerce. All attempts to defeat him failed, until a war hero named Veydal, who lived in an island kingdom in the middle of the Gugru Sea, volunteered to resolve the situation. He wanted to apologize to Leviathan and try to discuss with him. However, his first mate was too eager to fight and attacked the sea serpent before the order was given, which caused Leviathan to rampage.
Forced to defend his men, Veydal offered his life to Leviathan in return for theirs. The rest of his crew fled, including the first mate. Veydal was last seen falling into the sea in fierce combat with the serpent. Upon returning home, Veydal's first mate claimed the victory as his own. However, the next day, Leviathan's body washed ashore, with Veydal's sword planted in his skull. The serpent wished to honor the memory of the brave warrior and show the truth to his kinsmen, in a dying effort.
Altana, moved by Leviathan's gesture and Veydal's courage, called them both to the heavens. She transformed Leviathan into the Celestial Avatar of Water. Veydal is the name of the brightest, dark-blue colored star of the Leviathan constellation.
Summoners can unlock the "spell" Leviathan upon completion of the quest "Trial By Water". Alternatively, a brave low-level Summoner may go on the quest "Trial Size Trial By Water" and defeat Leviathan in a battle alone rather than in a group.
When summoned, Leviathan will join the Summoner's party, having its own HP, MP, and TP stats for the player to monitor.
Leviathan is resistant to water and fire-elemental based attacks and enfeebling effects, but has lower resistance to lightning-elemental attacks and debuffs. When a Summoner uses the Avatar's Favor ability, Leviathan will perform an ability that increases the magic accuracy of all party members within range of the summon.
He retains his trademark move, Tidal Wave as his Astral Flow ability.

Leviathan (Biblical Hebrew לִוְיָתָן or לווייתן Liwyāthān) is a violent sea creature referred to in the Hebrew Bible as well as the Talmud and some other ancient Jewish texts. During the golden age of seafaring, the term Leviathan became synonymous with any large sea creature, sometimes describing whales. Bible scholars interpreted Leviathan to be either a demonic sea creature and an enemy of God.
The Talmud and other ancient Jewish sources refer to Leviathan more specifically as a sea serpent, sometimes with multiple heads capable of breathing fire, that was made on the fifth day of Creation. It is said that during the end of days, God will make tents, or sukkah, out of the skin of Leviathan for the righteous to live in. Some have speculated that Leviathan was based on a real animal, the most popular theory being the Kronosaurus and the Nile crocodile.
In the Final Fantasy series, Leviathan is sometimes referred to as the King of the Seas. Its incarnation in the series appears to derive from the legends of the Shinto god Ryūjin or Owatatsumi, said to be the dragon god that reigns over the seas. It also resembles the Chinese dragon, mystical beings seen as the rulers of moving bodies of water, and the Dragon God as the dispenser of rain.
