Very little is known about Walkers. However, Dresden faced one, barely surviving, when he was sixteen. Three of them are known in the series: He Who Walks Behind, He Who Walks Before, and one other.
They are capable of powerful psychic attacks and enjoy launching them. They can leave a mark on those they hunt that can be seen with the Sight, or through the use of the ThreeEye drug. According to Lasciel, He Who Walks Behind is an Outsider, "the most potent of Walkers, and a powerful knight among the ruling entities"—and Harry overthrew him.

In Cold Days Harry faced off with Sharkface—whose real name is He Who Walks Before—several times in the book. He first faced him in McAnally's Pub. After He Who Walks Before left the bar, McAnally let Harry know there are three Walkers symbolically using three beer bottles. He later faced him just off the shores of Demonreach, where Harry and the Wild Hunt tried to foil Sharkface's plot to free the Naagloshii and the Dark Gods buried underneath the island with an army of Outsiders.
