When Mordetzky was called up to the main roster, WWE showed vignettes outlining him as "The Masterpiece", touting him as having a body so perfect, it would appear he was sculpted out of stone. Mordetzky credits Matt Morgan for creating the "Masterpiece" gimmick, and said Vince McMahon encouraged him to emulate former wrestler Paul Orndorff. WWE Championship pursuits (2005–2006) "The Masterpiece" Chris Masters made his debut in WWE on Raw as a villain, drawing attention to his physique in bodybuilding poses during his entrance to the ring. On the February 21, 2005 episode of Raw, Masters made his debut by defeating Stevie Richards. During the contest, Masters broke Richards' nose performing the Polish Hammer. The Polish Hammer continued to be a signature move of Masters' for months after this first match, but with warning that it would only be used in striking an opponent's chest.

After defeating the 400-pound Rosey on July 18, Masters defiantly stated "it doesn't matter how big they are!", prompting The Big Show to accept a Master Lock Challenge. In accordance with his villainous persona, Masters fled, refusing a match with the Big Show. In late August, Masters entered a feud with Shawn Michaels, leading to a tag match between himself and Carlito against Ric Flair and Michaels. During the match, Masters
