This Collider feature ranks the nine Stephen King novels in which Randall Flagg appears, the recurring shape-shifting villain who lacks the screen fame of characters like Pennywise or Annie Wilkes but outstrips them in sheer number of appearances across King's bibliography.

The article works through the ranking from weakest to strongest inclusion, discussing books such as The Wind Through the Keyhole, Song of Susannah, The Gunslinger and The Drawing of the Three, noting how prominently Flagg (or his aliases, including Walter O'Dim and Marten Broadcloak) features in each.

– Randall Flagg appears in nine Stephen King novels, more than IT or Misery's villains.
– The Gunslinger reportedly gives Flagg his biggest and most central role.
– The Wind Through the Keyhole and Song of Susannah feature him only briefly or peripherally.
