Proxies are slender mans human slavesEdit
The exact process by which the Slenderman creates proxies are unknown.
Those who willingly serve the Slender Man. Agents are most likely the most coherent type of proxy, being possessed of a sane human's mental facilities.
Hollows are people who have been "Carved out" by their contact with the Slenderman, which has erased their personality to make way for a almost zombie-like obedient servant. They often communicate through codes and cryptic messages.
Revenants are proxies that have their own powers similar to the Slenderman. Most Revenants are able to slenderwalk and use The Path Of Black Leaves.
