Characteristics
The Crimson King has taken many forms throughout the series. In The Dark Tower VI, Susannah tells Mia that, in her world, people see the Crimson King as a horned, red-skinned monster called Satan. As evidenced in Insomnia, the Crimson King is a shapeshifter; like the titular creature in It, he takes the form most terrifying to whoever confront him. When he is injured by Ralph Roberts, he reverts first to a handsome, blonde man, and then to a creature Ralph is unable to see properly, suggesting that his true form cannot be comprehended by human beings. When he finally appears near the end of the Dark Tower series, the Crimson King has the appearance of an old man with white hair and one fang, but in the comics he appears both as a monstrous entity with spiderlike characteristics much like his son Mordred, as well as a bald man with a large tusk or horn on his head. Throughout all of his appearances his one defining characteristic is his blood red eyes, which fascinate anyone who looks into them. Patrick Danville also mentions that the King fades in and out of view due to his transcendent magical powers.
The Crimson King prefers to work from behind the scenes. His sigil, a glaring red eye, is seen throughout each of the books in which he has appeared. He employs other people to do his bidding, as well as numerous supernatural beings, including Atropos, Mr. Munshun, Dandelo, Randall Flagg, John Farson, and various vampires, low men, and taheen.
