Man, those government acronym writers pulled off a big one, figuring out how to subtly name the project, “King of the Underworld.” Ya get it? They’re claiming that Satan was the true creator of the Heavens and Earth, along the lines of gnostic Satanism.

Osiris is not a Satan equivalent. If anything he is more a Christ like figure. Died and resurrected to judge the quick and the dead.

Set would be closer to what you are looking for. But still not quite there.

Apophis (which is the next asteroid to be sampled by the Osiris) is pretty much what you are looking for. A serpent of darkness and chaos.

And if it hits earth there would be lots of darkness and chaos but looks like that is pretty improbable.
