Robert "Chop Top" Sawyer was one of Leatherface's many siblings, who had the side of his head injured in a machete fight in Vietnam. He bought the texas battle lands using fake government cheques. He carries around nubbis, and acts as thought he's still alive. He also stashed a grenade in nubbis jacket. He dresses as a hippy and states "music is my life" he also wore a sonny bono wig (until leatherface ruined it) he also carries around a hanger and a lighter wich he uses to burn the tip of the hanger and peel flesh near the plate on his head to eat.
He is first seen when a couple of teenagers make him and Bubba (Leatherface) swerve off of the road so later they go back for revenge Chop Top follows them driving back wards and Leatherface kills the teens. he didn't know it was being recorded/broadcasted so he and letherface went to kill Stretch. while chop tried to distract strech leather face burst out and accidently hit chop top on the plate, which caused him to shout "non flash back non flash back" and also "dog will hunt". while he rumeged through the record vault L.G. walked in he tried to stop him but he over powedered L.G. and repetedly beat him to death with a hammer witch he thought killed him.
After he believed Leatherface killed Stretch he and Leatherface left. Little did he know that Stretch acutally didn't die and followed them. when chop top did realise she followed them he captured her and tied her up and went to go get grandpa. befor they could kill her lefty came to her rescue she ran and chop top follwed her to chain saw heaven. she quickly riped the chain saw from grandma sawyer's stomache chop to lighty slit his throught twice whilst screaming 'look! look at my face!". chop top watched as grandma sawyer died and said in rage "you killed her you hog bitch!" while Stretch tired to start the chain saw he viciously stabbed her with his razor but strech got the chainsaw started and cut chop top's stomach making him fall back wards into a wall which broke and he fell into an air duct. It was later revealed that he survied both the cut and the fall.
