Lawrence Robert "Larry" Shreve (born on January 11, 1941) best known as Abdullah the Butcher, and also at times The Madman from the Sudan, is a semi-retired Canadian professional wrestler known as one of the most brutal or "hardcore" professional wrestlers of all-time.

The scars on his forehead are the result of frequent blading. According to Mick Foley, Shreve used to put gambling chips into the deep divots in his head to entertain (or scare) people at casinos. However, New Jack claimed in his RF Video shoot interview that the grooves in Shreve's head were surgically implemented.

An amateur martial artist, Shreve also has knowledge of judo and karate, often including this knowledge in his professional wrestling matches. This knowledge was mainly displayed by him using judo style throws, and karate chops.

Shreve grew up in Windsor, Ontario, Canada as part of a family of ten people in a deeply impoverished household. He learned karate and judo as a youth and, teaching fellow children in the backyard, claims to have eventually earned the title of seventh-degree grandmaster.

Following that night he went into training with Buddy "Killer" Austin, Pat O'Connor, and Bob Geigel. A couple of years later he was ready, standing 6'5" and weighing 342 pounds (hence the nickname "Ox"). He began his pro wrestling career by defeating Frank Hickey in Kansas City, and later the Missouri Mauler as well. As time went on he was winning a majority of his matches by knock out caused by the Heart Punch (which he borrowed from Stan Stasiak) and adapted into his own ring arsenal. He would later rename the move the Hurt Punch after Stasiak objected.
