In 2005, he debuted in WWE as "The Masterpiece" Chris Masters, a wrestler in a great body shape, using "The Masterlock" as finisher, a full nelson hold.

When Mordetzky was called up to the main roster,[3] 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.

[10] "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.

Masters would go on to log more full nelson submission victories than any wrestler in WWE history, breaking the record previously held by Kurt Angle.

[22] This set up a Triple Threat Submission match for the November 28 edition of Raw with Cena defending his title against Masters and Kurt Angle, with whom he had already been feuding.

[22] Masters portrayed the role of a bailiff during the mock trial for then General Manager Eric Bischoff on the December 5 episode of Raw, with WWE Chairman Vince McMahon as judge.

On December 12, Chris Masters defeated Viscera on an episode of Raw to gain a spot in the Elimination Chamber match for John Cena's WWE Championship at New Year's Revolution.

On the December 26 episode of Raw, Masters faced Chavo Guerrero, in a Beat the Clock match to determine who would be the final entrant to be released from his pod in the Elimination Chamber.

On the February 27 episode of Raw, McMahon offered Shawn Michaels' former tag team partner Marty Jannetty a WWE contract in exchange for kissing his exposed buttocks in the middle of the wrestling ring.

On the March 6 episode of Raw, McMahon publicly thanked everyone who encouraged the previous week's events, and officially awarded Masters and Carlito a World Tag Team Championship match at WrestleMania 22.

[35] Along with less muscle mass, he sported a goatee and mustache leading Jerry "The King" Lawler to refer to him as a "leaner and meaner" Chris Masters.

[55][56] On November 2, 2007, it was reported that Masters had been suspended for 60 days for having violated WWE's Substance Abuse and Drug Policy a second time.

[59] Mordetzky also appeared under his Chris Masters ring name and gimmick at Harley Race's World League Wrestling show on December 29, during a Lumberjack match between Branden Tatum and Dinn T. Moore.

[63] He faced Montel Vontavious Porter in a match that resulted in a double-countout after he applied the Master Lock submission to MVP outside the ring.

[65] On the November 2 episode of Raw, Mordetzky entered the Raw's Got Talent show hosted by guest host Ozzy Osbourne, Sharon Osbourne, and The Great Khali, where he performed a "special performance art piece"; he flexed his pecs to the beat of Ozzy's song "Crazy Train", earning a positive crowd reaction.

Some wrestling observers have speculated that his character was being reduced to a comedic role because WWE hoped to avoid negative publicity tied to his past Talent and Wellness Violations.

In December 2011, Mordetzky joined the Ring Ka King promotion, a branch of Total Nonstop Action Wrestling for India under the name American Adonis.

In April 2012, Mordetzky participated in the Revolution event for International Pro Wrestling: United Kingdom (IPW:UK) in London.

On October 27, 2012, Masters defeated Rik Luxury, Sean Casey and then-Champion Chavo Guerrero Jr. in a Four-Way Elimination match for the Vendetta Pro Wrestling Heavyweight Championship.

[88] On June 26 Masters defeated Ken Kerbis & Kronus in a triple threat match for the AWO Championship at the All Wrestling Organization annual show Wrestlefest in Tira, Israel.

On the July 27 episode of Impact, Adonis, Eli Drake and Ethan Carter III defeated Eddie Edwards, Naomichi Marufuji and Moose in a six-man tag team match.

[96] According to Mordetzsky, he left the promotion due to the low salary and the fact that the company did not have any plans for him besides being a manager for Eli Drake.

[99] After this, Adonis turned heel when he aligned with Thom Latimer and NWA World Heavyweight Champion Nick Aldis, as the new member of Strictly Business.

[104] On June 3, during night one of the Crockett Cup, Adonis teamed with Tyrus under the name "The Midnight Riders" to compete in the namesake tournament, defeating The Warriors from the Wasteland (Judais and Max the Impaler) in the second round,[105] and The Immortals (Kratos and Odinson) in the quarterfinal but lost to Knox and Murdoch (Mike Knox and Trevor Murdoch) in the semifinal.

On the October 17 Powerrr, Adonis defeated Zyon by disqualification to earn an opportunity at "Thrillbilly" Silas Mason's NWA National Heavyweight Championship at Samhain in a Burning Lake Brawl.

"[110] In the official write-up for the World Wrestling Entertainment website, Masters’ physique has been called "the kind of you usually only seen in comic books", and he was praised for his "unbelievable build and his devastating finishing maneuver".

"[112] Wilkinson added that Masters was known for his wrestling entrances when he flexed and "did pectoral dances to amuse fans, which also proved how impressive his body was,"[112] a sentiment shared by Travis Wakeman from TNT Sports, who thought that the wrestler was memorable because of his "great physique, as well as an arrogant personality".

[120] A tweet posted to his Twitter profile in March 2013 stated that Mordetzky saved his mother's life from a criminal who had committed arson at her home.
