Leviathan

A massive sea serpent that effortlessly controls water and rules all who dwell in the oceans. The raging swell of his "Tsunami" is enough to consume even the fiercest of foes.

Dissidia Final Fantasy Summon Compendium

Leviathan (リヴァイアサン, Rivaiasan? or リバイアサン, Ribaiasan?), also known as Levia, Leviatan and Leviathn, is a summon in the Final Fantasy series.

Leviathan's gender varies by game, although it is typically treated as male on most installments, while some games have established Leviathan as female. A giant sea serpent, he first appeared as a monster that swallowed the party in Final Fantasy II. Leviathan has since gone on to become one of the most prominent summons in the series alongside Bahamut, being known by titles such as "the Sea King", or "Lord of All Waters". In the later titles of the series, Leviathan's prominence diminished in comparison to Bahamut.

Leviathan's trademark attack is Tidal Wave, also known as Tsunami, which calls on a massive wave of water to damage all enemies.

When Rydia is crossing the ocean with Cecil, Edward, and Yang to Baron, Leviathan attacks the ship and carries Rydia off into the Feymarch to protect her and train her in her summoning abilities. Later on the player can enter the Feymarch and defeat Leviathan to earn him as a summon if they have also defeated Asura.

Leviathan has a casting time of 3 and costs 50 MP to summon in 2D releases. In the 3D releases he costs 75 MP. Leviathan uses Tsunami to attack all enemies for heavy non-elemental (water-elemental in the 3D version) damage. In the Easy Type version, the casting time was reduced to 2.

Leviathan is fought twice. The first time he is summoned by the Mysterious Girl to battle Golbez and Fusoya in the Crystal Palace. He cannot be harmed and only the Girl can be defeated, and afterward Leviathan fades away.

In the final chapter, Leviathan is fought in the Depths, and if defeated with Rydia in the party, will come to his senses and be available to summon. Otherwise, he will be killed. Leviathan costs 50 MP to summon and uses Tidal Wave to attack all opponents.

Leviathan is a summon in Final Fantasy VII Remake who can be earned by defeating it in its Shinra Combat Simulator mission. It is also the third of five fights in the "Three-Person Team vs. Top Secrets" challenge.

Leviathan's Tsunami attack is a water-elemental attack that damages all enemies, washing them off screen if they are defeated by the attack. Its compatibility item is Fish Fin and its opposing GF is Quezacotl whose summoning deducts from Leviathan's compatibility the most.

Leviathan learns Magic and Spirit junctions and elemental attack and defense. It is the only Guardian Force to learn the Recover command naturally, which deals a full heal up to 9999 HP to a target and can thus also be used to damage undead opponents. It learns a support ability that has the junctioner automatically use a recovery potion when they are hit by an enemy. Its unique abilities make support magic and GF recovery medicine from items, and an ability that boosts the user's Spirit upon level up.

Its Triple Triad card modifies into Doc's Codes and is held by CC Group Joker in Balamb Garden Training Center (he appears randomly in the easternmost screen after Garden has become mobile).

Final Fantasy XIII-2[]

Leviathan is mentioned in Captain Cryptic's Confounding Quiz as a Cocoon fal'Cie responsible for purifying the water.

Final Fantasy XIV[]

Leviathan appears as the primal of the Sahagin beastmen tribe.

Leviathan was originally scheduled to appear as a boss in the original version, but following the tsunami disaster of 2011, his and Titan's plotlines were seen as inappropriate for the time and were shelved.

In A Realm Reborn, Leviathan appears as the final boss of the "Through the Maelstrom" scenario introduced in the game's 2.2 patch. Leviathan first appears during the "The Gift of Eternity" main scenario quest, during which he is summoned by a Sahagin Priest. Leviathan absorbs the spirit of the priest and dives into the ocean. After obtaining a specially-outfitted boat, the Whorleater, to fight the primal on equal footing, the Warrior of Light and their allies defeat Leviathan out at sea. His signature attack during the battle is Tidal Wave, which can be defended against by activating a force field powered by an Elemental Converter.

In addition to the scenario version of the boss, players may face a stronger version of Leviathan in "The Whorleater (Extreme)" instance, which offers the chance to obtain Leviathan-themed weapons and several drops for crafting furniture and stylized chocobo barding.

Another Leviathan appears as a boss in Final Fantasy XIV: Shadowbringers at the Eden Raid series; this version of the primal is summoned from the memories of the Warrior of Light via the Eden's power to restore water-aspected aether to the wastelands of the Empty. Like with other primals summoned from Warrior's memories, the version of the entity appears different then the one on the Source, in this case, with two heads.

Defeating him in both story and Savage difficulty will award player with currency to exchange for equipment with white and gold angelic appearance, along with other three battles in the initial tier of the raid.

Final Fantasy XV[]

Leviathan is one of the Six Astrals, and is commonly known as the Hydraean or the Tidemother. She sleeps in the waters of Altissia, and is awakened by Lunafreya, who wishes for Leviathan to lend Noctis her power. She is the largest Astral in Eos, and is a colossal sea serpent.

She is fought as a boss in Chapter 9. Noctis can summon her after forging a covenant with her.

A King's Tale: Final Fantasy XV[]

The player can summon Leviathan via crystals.

Final Fantasy XVI[]

Leviathan is one of the eight Eikons of legend, serving as the Eikon of Water. Unlike the other Eikons, Leviathan does not appear in the main game, only being depicted on murals and being mentioned briefly as "Leviathan the Lost". Instead, Leviathan plays a central role in "The Rising Tides" DLC, where it is fought as a boss.

Final Fantasy Tactics[]

Description

Leviathan can be learned with 850 job points. Summoning it costs 48 MP and it unleashes Tidal Wave, a water-elemental attack that hits all foes in a large area. It has a speed of 15. Leviathan has a 40% chance of randomly being learned in battle by a Summoner who has not yet learned it and is not KO'd by it, or absorbs at least 1 HP worth of damage. Nullifying the damage does not count.

In the PlayStation version, when summoned, the summoner will sometimes say, "Sea fang, attack with water's power! Leviathan!"

Leviathan is a minor antagonist and is a servant of Chaos. Leviathan's appearance is extremely different from the main series, as he appears as a squid-like creature with six serpents for tentacles.

Leviathan began to cause trouble in Liberte around the time of Glassworks Fair. He had sent his minions to make Captain Drake and his crew attack the city to steal all of the objects in Liberte's town hall. The captain and his crew stole Pione's vase with Lilibelle inside, and the Rusty Compass. After the Rusty Compass was stolen, the Cetus was forced into an eternal slumber and city of Liberte was overrun by Leviathan's minions.

After being sent into the past, the Heroes of Light travel to Liberte a day before the events of the Glassworks Fair and help Pione by bringing Lilibelle for his vase. The next day, the party discovers that Captain Drake and his crew robbed the city of the artwork and kidnapped both Pione and Lilibelle. The party travels to the Pirate Hideout and discovers that Captain Drake was being manipulated by Leviathan's minion. The party defeats the Sea Devil and frees Pione and Lilibelle.

Captain Drake apologizes for his actions and gives the party the Rusty Compass. The party returns to Liberte and resurrects the Cetus. The party then takes the Cetus to the east and defeats Leviathan, bringing peace to Liberte. Later, Leviathan is revived within the Star Chamber, but it is defeated once more.

This Leviathan also appears in the Bravely series.

Influences in other titles[]

Cygames, Inc's browser title, Granblue Fantasy, features Leviathan as a primal beast summon of water, being the incarnation of the Auguste Isles. The game's designs for Leviathan and Leviathan Omega are heavily inspired by the Final Fantasy series version of the summon. Their summon attacks, Cascade and Perilous Tidefall, are also similar to Final Fantasy's Tidal Wave attack, causing a massive wave of water to drown the battlefield. Granblue Fantasy borrows a majority of its influences for summons from Final Fantasy, featuring several alumni from the series among its development staff and artist studio, CyDesignation.

Due to both Cygames and CyDesignation also being involved in several other mobile titles, the Leviathan of Terra Battle, Rage of Bahamut, and Dragalia Lost take design elements from the Final Fantasy version of the summon.

Other media[]

Etymology[]

[view · edit · purge]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. The Ugaritic equivalent being Lotan. 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.

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.
