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 Dresden overthrew him.

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