Arkaroo

Arkaroo is one of three primordial entities, along with Weshir and Tezcat, that make up the existential entity known as Mana. Arkaroo takes the form of an enormous rainbow-colored serpent, much like the wonambi native to Kangaroo Island on Atlantea. Arkaroo is older than the mortal mind could possibly fathom, being trillions of times older than even this universe, which is only one of trillions of universes that have existed since the very beginning. Arkaroo creates the universes, Weshir preserves them, and Tezcat destroys them when their times have come.

Arkaroo, in bursts over the course of thousands of years, brought this universe into being, as well as creating (either directly or indirectly) the beings that inhabit it. He also formed the dimensional barrier that separates the Physical Realm from the Nether Realm. After a chain of events that saw six mortals accidentally moving him to the Physical Realm and reawakening him via Shadow Magic, Arkaroo slithered through the South Galaxy in panic, creating hundreds of star systems, almost all of which would become UNISYN colonies millennia later.

Arkaroo was later returned to his eternal slumber by the first MOLAS, Sid. However, thousands of year later, the evil warlord Tate very nearly succeeded in waking him up.
