C. W. Saturn
The "agent of the Underworld," C.W. Saturn is purely evil and appears to be demonic in nature, being "neither man nor woman, not animal, vegetable, mineral, or energy." He serves his master, Samael, who sits upon the throne "of heinous authority; the centerpoint of Creation's evil." Throughout history, Saturn has been responsible for some of the worst events in humankind, including indirect responsibility for the death of Abraham Lincoln.
In 1981 Saturn was dispatched as an "agent of Hell on earth" by Samael to ruin the moral fabric that comprised Superman's identity. He found passage to earth through a dimensional tear created by a Lex Luthor prison escape, and upon arrival possessed the body of young Kristin Wells (see Superwoman), challenging Superman to forsake his sacred oath and kill her.
Saturn failed in his attempt to get the best of Superman, and each year Superman's victory over evil is commemmorated on the third monday in May, the holiday known as Miracle Monday.
