Big Boss Man (wrestler)

Context: Traylor rejoined the WWF shortly after his WCW release and once again became "Big Boss Man". On October 12, 1998, he returned to television with a new look, abandoning his blue police shirt for an all-black SWAT-style uniform, including a tactical vest and gloves. He served as Vince McMahon's bodyguard during his feud with Stone Cold Steve Austin and his later feud with D-Generation X. He briefly wore a mask, before his identity was revealed.  Boss Man was one of the first members of McMahon's heel stable, The Corporation, and served as a bodyguard for other members, such as Vince's son Shane. While in The Corporation, Boss Man won the Tag Team Championship with Ken Shamrock, won the Hardcore Championship four times, and lost to The Undertaker at WrestleMania XV in a Hell in a Cell match. After this match, The Undertaker hanged him from the roof of the cage (an illusion made possible by a body harness concealed under Traylor's outfit).  In the WWF's Hardcore division, Boss Man's major feud was with Al Snow, a feud that eventually involved Snow's pet chihuahua, Pepper. At SummerSlam, the two had a Falls Count Anywhere match that spilled into the backstage area, the street and, finally, into a nearby bar. Just prior to the match, Snow had set Pepper's pet carrier near the entranceway. Minutes into the match, Boss Man picked it up, taunted Pepper, struck Snow with the carrier and carelessly tossed it behind him. Commentator Jim Ross immediately apologized to viewers for the act, and stated that Pepper had been removed from the box before the match.  Two weeks later, Boss Man kidnapped and ransomed Pepper, arranging a meeting in which he fed Snow a meat dish supposedly made from Pepper's remains. The two settled their feud in a Kennel from Hell match at Unforgiven, in which a blue solid steel cage surrounded the ring, itself and ringside surrounded by the chain-link fenced "cell". The object of the match was to escape from the cage and the cell while avoiding "attack dogs" (which turned out to be disappointingly docile) positioned outside the ring. Snow won the match and retained the Hardcore title, which had been returned to him by Davey Boy Smith, who had defeated Boss Man for it. Boss Man would later win back the Hardcore title in a triple threat match involving Al Snow and The Big Show, and would hold it until January 2000, when he lost it to Test.  Boss Man then feuded with The Big Show over the WWF Championship. During the feud, Boss Man showed up at Big Show's father's funeral, made some disrespectful remarks, then chained the casket to the back of his car and drove off. The Big Show attempted to save the coffin by jumping on it, riding it for a few yards before losing his grip and tumbling off, the feud also included a segment in which Boss Man invaded the home of Big Show's mother and forced her on camera to admit her son was born an illegitimate child. Boss Man became the #1 contender for the WWF Championship by defeating The Rock on the November 15, 1999 episode of Raw. At Armageddon, The Big Show defeated him to retain the title and end the feud.
