Leviathan is a boss in the Advance, mobile and Steam versions of Final Fantasy VI. It can be fought by taking the ferry between South Figaro and Nikeah once the party has acquired the Falcon, but will not appear unless the party has talked to a man in South Figaro who mentions seeing a shadow while fishing.
Leviathan starts the battle with Tsunami and uses it periodically with Aqua Breath and El Niño. He has a powerful physical attack and counterattacks with Entangle, which inflicts Slow. Leviathan's Water attacks hit the entire party and cannot be blocked.

Leviathan (Biblical Hebrew לִוְיָתָן or לווייתן Liwyāthān) is a violent sea creature that is 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.
Being mentioned in the Final Fantasy series as the King of the Seas, its incarnation also appears to derive from the legends of the Shinto god Ryūjin or Owatatsumi, said to be the dragon god that reigns over the tides and the seas. This is further reinforced by the parallels of the Leviathan faith of Wutai in Final Fantasy VII, as Shinto also sees the worship of water dragon kami in Japan.
In some cultures it is believed Leviathan lives at the bottom of Mariana Trench.
