The most recurring and without a doubt, the most important villain of the entire Stephen King mythos, Randall Flagg is following King's own words, the best villain he created, whom he had in mind since he began writing. Randall Flagg goes by many aliases including Walter O'Dim, and Marten Broadcloak, but his real name is Walter Padick.

Randall Flagg is a demonic being that has appeared in multiple works, always as a powerful and charismatic embodiment of Evil. It was also implied that many of other Stephen King villains such as the unholy demon He Who Walks Behind the Rows in Children of Corn, or the deal-making fiend Leland Gaunt in Needful Things were a representation of avatars of some sort of Flagg, who shares similarities with the biblical demon Legion. Flagg was first introduced in The Stand, where he represented the concept of evil and stood in opposition to Mother Abagail, who represented good: the two fought for control over the survivors of a world plagued by disease.

Flagg's main purpose seems to be the bring about the end of civilizations by spreading destruction and sowing conflict and he has many supernatural powers by which to achieve his goals: such as necromancy, prophecy and the ability to look into the predatory nature of man and beast.
