The Benders are a family of cannibalistic hunters who live in Minnesota. They serve as the main antagonists of the Season 1 episode of Supernatural of the same name.
They first capture Sam when he and Dean are investigating an earlier disappearance. Dean and a local deputy then go looking for Sam (the deputy agrees to help Dean because her brother had also been captured) and discover the Benders' home. Missy manages to trick the deputy and lock her up alongside Sam. Dean sneaks into the house to try and rescue them, but is captured himself and interrogated by the whole family. Pa Bender threatens Dean with a hot poker, forcing him to decide which would be hunted, Sam or the Deputy. Dean chooses Sam, but instead of deciding to hunt him, Pa orders Lee to shoot Sam in his cage, then shoot the deputy too.
Sam is, thankfully, able to escape from the cage and beats Lee into unconsciousness. When he doesn't return, Pa and Jared go to investigate. They get into a scuffle with Sam and the deputy, which results in Jared being knocked unconscious. The deputy corners Pa and demands to know why he killed her brother, shooting him point blank when he replies simply because he thinks its fun. Dean is able to escape by locking Missy in a closet.
They are based on the actual serial killer family Bloody Benders.
