Leviathan

is a mythological figure from the Old Testament. 
==Profile==
===Background===
It is possibly also the cruciform snake staff linked to from Ugaritic myths. It is something with the same origin as the staff that Moses used to split the Red Sea, while also acting as a symbol of the sea that that staff split. Its owner will be granted a transformative property like that of water, making it feasible for them to adapt to any situation. Furthermore, their form will be able to change phantasmagorically, and it would even be possible to take the shape of the target of one's envy.
Leviathan is a giant demonic beast in the sea recorded in the Old Testament, the Book of Job. After the final judgement, a giant demonic beast is created to serve humanity. It is the demonic beast that lives on the land, the demonic beast Leviathan lives in the sea.
It is said that Leviathan and Behemoth were a match (pair), Behemoth was a gentle herbivore, but Leviathan was a ferocious beast.
Leviathan is considered by all to be female, and later drawn in the image of a giant serpent. Before the Middle Ages, the sea was adjoined with death for the people, it became considered as a devil because of its ferociousness, eventually it was circulated as a great demon that symbolized "jealousy" among "The Seven Deadly Sins". Leviathan holds a status after Satan and Beelzebub, and the authority as a naval admiral in hell. According to the Book of Job, it is excessively huge, causing the sea to swirl and rushing waves just by swimming.Fate/Grand Order material IX - Meltryllis (Swimsuit)'s profile translated by Konchew
