Shadow Behemoth

Description
In the Endless Ocean of Shadow of the Other, the colossal shadow behemoths were creatures woven from the darkness itself. A shadow behemoth was a composite of shadowy tendrils, mouths filled with dark teeth, and hateful, black eyes that rose to the surface of its umbral "flesh" like bubbles on foamy water.

Pure evil, shadow behemoths could not be controlled, not even by the umbras who shared a similar origin.

More than anything, shadow behemoths despised living creatures. These beasts hunted the edges of the Black Cauldron, hoping to grab a newborn Lost One before it was able to protect itself with the help of a Voice in the Dark or other benevolent creature.

Undead Nature. The shadow behemoth did not require air, food, drink, or sleep.
