Leviathan

"'The Enlightenment is before us all, for we will reclaim our once former forms as the beautiful, the angelic, and the most high of the false Flora, for we set forth the great journey of the maternal mother.'""- Neox telling Ryder De Aura before activating the Weapon of Mass Destruction."The Leviathan, (Maris angelus grandia, "Whales of the Sea"), are a bio-mechanical saurian species known for their grandiose size and religious intellect.

The Leviathans were once known as the Watchers of the Flora, having the responsibility in protecting and guiding humanity from the King-Emperor Zero's inter-dimensional serpents called the Zilliant, but once they created a weapon of Chaos, known as the LeviMECHA, they were punished by the Flora for their unflowerly ways. Their punishment is the fall of their once forms of angelic beings, now bounded in the material world as grotesque, heavy, and rusty creatures called the Leviathan. With the destruction of their home world known as the Womb, they were cast out into the infinite darkness of space, and swim in eternity until they repent of their unfruitful sins, which is why the humans call them the whales of the sea.

History
Long ago, after the Flora's creation of the multiverse, the Flora bestowed emanations of benevolent beings once called the Levian, entities who's sole purpose is to safeguard, watch, and guide the creators creation to its fullest potential. But once Infinity, the goddess of wisdom tried to comprehend the Flora, her fallen emanation laid the foundations of the material world, and the fallen spirit, called eFlora, released replicates of its misguided appearance into Zilliants, who scoured across the universe in hopes of degrading the creation of the Flora. By sucking the Nectar, life essence, or Fluorescence of mankind. The Levians soon took action to rid of these inter-dimensional entities in hopes of making the Floraverse good and with ever lasting light.

Levian-Zilliant War
For billions of years, the Levian and the Zilliants waged war against each other for the light and the dark of the Flora, using whatever means necessary in hoping to disperse the Zilliants from ever laying their hands on humanity.

But after eons of failure, they had only one solution, a solution to which they refused to do from the beginning of their creation, using the souls of humanity to create a unified consciousness weapon that would propel the primordial power that fuels the Zilliants. The Levians created the weapon of mass destruction called the LeviMECHA. A gargantuan mechanized Leviathan designed to resemble the Zilliants to further intimidate them.
