This is more of a confirmation to a previous theory that The Smoke Monster is the Egyptian character Apep.
Apep is "An Egyptian monster living in perpetual darkness. This snake god is the chief of the antagonists of the sun god Re and each night he tries to stop the sun god's barque on his journey through the underworld. In the struggle between light and darkness, the monster is wounded by the divine entourage of Re with knives and spears. The god Seth and the god Mehen were often depicted defending the solar barque.
Apep is the personification of darkness, evil, and chaos. Occasionally, the battle was decided in his favor, causing a solar eclipse, but his victories were of short duration for Re always triumphed in the end. Eventually, Apep was slain by Re, who cut up his body and burned it. The Greeks referred to him as Apophis.
