The Beast Forever is a creature responsible for Mother South's death. It's also the title of the first episode of the series.
The Beast is said to be able to take many forms - floods that meet the sky, fires that water cannot extinguish, monstrosities that slither and soar. The Wizard stopped the Beast before with the use of Eternal Warriors, who formed a wall along the Emerald City to keep the Beast Forever from flooding entire world.
Most Current Incarnation[]
As Anna mentioned to the Wizard, The Beast is prophesied to arrive when the two moon become one. It will come from the sky, have a brain, a heart, and relentless strength.
