The Korathos walks on two sturdy legs, and has a broad yet muscular looking torso that is set in a hunched stance and is dark in color. Near the base of the split tail lie various curved and crooked growths with the tail splitting in two, a red stripe flowing down to the tips on the inside of both tails. It has two long arms with hands that have three fingers on each. On its neck are spike-like growths and at the head it has nine gleaming white eyes with no pupils in each of them along with a mouth of sharp teeth. Near the base of its bottom jaw are four long tentacles with uniquely shaped appendages at the end of them with multiple spots similar to Korathos' eyes in each of them, the tail having those same appendages at the ends of them. The feet are in a position similar to various birds of prey, having the middle part of each toe bent inward to support its massive body. Also has multiple large spikes on their back that have a thin glowing pattern to them. Korathos are massive, ruthless hunters of the night that utilize their dark coloration to remain undetected. The frilly plates along their neck and tail can pick up vibrations and can be shaken to create an ominous rattling sound. Korathos have a cold intelligence to them and often seek to taunt other creatures.
