The Hillbilly

In another place and time, he would have been called Max Thompson, Jr. Unfortunately, Max Sr. and his wife, Evelyn, were so ashamed at their deformed child that, rather than name him, they bricked him up in a room and fed him through a hole in the wall. Needless to say, their son did not appreciate this and made that quite clear when he finally escaped. The bodies of Max and Evelyn Thompson were never found, but the disemboweled carcasses of just about everything else that made Coldwind Farm its home were.

The farmland was eventually resettled, split up, and sold. All of it except for the farmhouse, where one could hear the sounds of a chainsaw throughout the nights...

As a Killer, the Hillbilly charges Survivors at high speed with his chainsaw which drops them into the Dying State if it connects. His teachable perks Enduring, Lightborn, and Tinkerer allow the Hillbilly to weather attacks that would stop other Killers in their tracks and sneak up on Survivors when they're on the verge of repairing a generator.
