Leviathan Scales (水神様のうろこ, Mizugami-sama no Uroko?) are a key item in Final Fantasy VII, located in the Junon Underwater Reactor in the chest on the far left in front of the user-controlled Submarine.
The item is used in the cave in Wutai on Da-chao Statue. If the player climbs Da Chao and enters the cave, the flames that block the path react with the scales, dousing them. This leads the path to the Steal as Well Materia, as well as a weapon for Yuffie, Oritsuru. If the Leviathan Scales are missed, they can never be obtained again.
Leviathan Scales makes an appearance as a trade accessory.
Leviathan (Biblical Hebrew לִוְיָתָן or לווייתן Liwyāthān "coiled") 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.
- The scales are referred to as "Scale of the Sea God" when used in the Da Chao cave.
