Leviathan, also known as the Hydraen, is an astral who appears in Final Fantasy XV. She is one of the Six and a sea serpent who controls water. Leviathan slumbers under the waters of Altissia. She is usually referred to as the "The Tide Mother" and looked upon with both fear and respect. Prince Noctis forges a pact with Leviathan in Chapter 9.


Like the other astrals, Leviathan is based on a recurring summon in the Final Fantasy series, although in other games Leviathan has been referred to as being male. In Final Fantasy XV, she is a giant blue sea serpent with multiple wing-like appendages. She is the largest astral, and known for her ferocity. She seems to have little affection for mortals, and considers they should respect her unconditionally for how powerful she is. During Lunafreya Nox Fleuret's attempt for Leviathan to forge a covenant with Noctis, she attacks Luna to intimidate her. Leviathan does seem to respect resolve, as when Luna vows Noctis would prove his worth, Leviathan agrees to test him.

Leviathan and Luna

Lunafreya Nox Fleuret stands before Leviathan.

Lunafreya Nox Fleuret, the Oracle, wants to awaken Leviathan to ask for her to lend her powers to Noctis Lucis Caelum. She travels to Altissia for this purpose, and becomes sheltered by the local government. The first secretary of Altissia is reluctant to let Luna perform the summoning, as Leviathan is known for her wrath and she worries for the damage it would cause the city. Noctis negotiates with the first secretary and gains her alliance. Luna is given the traditional trident of the Oracles to call for Leviathan, and after giving a speech to the masses as to her intentions, she approaches the Hydraean. The trident is said to have been given to the Oracles' bloodline by Bahamut in ancient times, but is now kept in Altissia for a means of awakening Leviathan.

Leviathan takes offense to being awoken by a mortal, stating that Noctis must earn her power. Leviathan is attacked by Niflheim forces, and goes on a rampage across the city. Noctis hitches a ride to Leviathan's side on a Niflheim magitek vehicle piloted by Prompto, but when he asks for her power she rejects him. Luna repels Leviathan's attacks with her trident, but is stabbed by Chancellor Ardyn Izunia of Niflheim while Noctis is unable to help her. Luna uses the trident to call upon the souls of past kings of Lucis to empower Noctis, who fights Leviathan wielding the power of kings.


Noctis forges a covenant with Leviathan.

After Noctis wounds Leviathan, he is left lying unconscious on a piece of broken pier. The astral god Titan who had forged his covenant with Noctis earlier, appears to shield Noctis from the enraged Hydraean. Leviathan submits and forges a covenant with Noctis, seeing this as proof of his worth. Despite this, Titan creates a tsunami that engulfs the upper city, as well as Noctis and Lunafreya. She periodically appears to help Noctis during his battles from there on out whenever he is close to death.

Noctis continues on his journey to reclaim the stolen Crystal. When the train they are on is attacked by Niflheim forces, Leviathan appears to dispatch them.

Spoilers end here.


Noctis obtains Leviathan at the end of Chapter 9.


After gaining the astral's blessing, the chance to summon them will appear randomly, and the player can summon once per battle. Each astral has its own requirements to be considered during the "summon roll", which happens every 10 seconds. While possible to summon during the first roll, it is rare. Leviathan requires Noctis to be in Danger state and in an open area near to water. Leviathan can be summoned in Insomnia due to its water elements.

Leviathan is capable of disguising herself and traveling in liquid form. When summoned, Leviathan will engulf all enemies in the area in a massive tidal wave.


Leviathan is fought at the end of Chapter 9. Noctis must defeat her by first dodging her attacks in the first phase, before finishing her off with Armiger.

Creation and developmentEdit

Leviathan in the E3 2013 trailer.

Leviathan was one of the first astrals to be designed for Final Fantasy XV. She was planned to appear even when the game was known as Final Fantasy Versus XIII.[1] She appears in the E3 2013 trailer, which was some of the first footage created for Final Fantasy XV after its transition from Final Fantasy Versus XIII. The trailer doesn't run in the final Luminous Engine, and is a concept for the scene.

Tomohiro Hasegawa was in charge of art direction for enemies. He purchased fish, dissected them and looked at how light and surface reflection worked for designing Leviathan's scales.[2]

Other appearancesEdit

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.

Leviathan is also one of the seven princes of Hell associated with the deadly sin Envy and Hell's gatekeeper in Christian demonology.

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.
