Debut, Tag Team Champion (1993–1994)

Upon coming to the WWF, The Harlem Knights were given a new gimmick: Nelson became Mabel, Bobby became Mo, and they were given a rapping manager named Oscar.^[6] The new team, dubbed Men on a Mission, was introduced to the WWF audience through vignettes portraying them as three African American men trying to make a positive change in inner city neighborhoods in June 1993. Clad in purple and yellow, sometimes pink and turquoise; they debuted as solid faces.^[7] At WrestleMania X, Men on a Mission defeated the WWF Tag Team champions, The Quebecers, by countout, but did not win the belts. On March 29, 1994, they won the title at a house show in London, England. The Quebecers regained the title two days later in Sheffield, England.^[8] In mid-1994, Mabel began wrestling more singles matches; he was seen as the spectacle of Men on a Mission due to his size, the "special attraction" that got used to make rising stars look good. He competed in the 1994 King of the Ring tournament, defeating Pierre of the Quebecers in the qualifying round before losing to IRS in the quarterfinals.^[9] He then had a match that pit "Rap vs. Country" against Jeff Jarrett at Summerslam, which Jarrett won.^[10]

King of the Ring, departure (1995–1996)

In March of 1995, Men on a Mission lost a title match against the reigning tag team champions Smoking Gunns. Mabel and Mo brutally assaulted them afterward, but offered an apology and brought Billy and Bart Gunn out after a match a few weeks later for a handshake. It proved to be a ruse, however, as Mabel and Mo not only beat up Billy and Bart, but also turned on Oscar and became heels.^[7] Mabel dropped his fun-loving, positive personality in favor of adopting a more thuggish image and received a push as a singles wrestler, winning the King of the Ring tournament in June,^[11] After that, Mabel became known as King Mabel, with Mo becoming "Sir Mo", his manager.^[7] Mabel was awarded a championship belt, designed and created by belt maker Reggie Parks. The belt, engraved with "King of the Ring", is one of a kind, as the World Wrestling Federation had not before or since created a belt for the King of the Ring. This belt was never seen on WWF television.^[12] After his victory King Mabel became the top heel in the company and challenged WWF Champion Diesel at August's SummerSlam.^[13] Just before SummerSlam, the WWF turned Davey Boy Smith, one of the company's more popular wrestlers, against the fans, replacing Mabel as the company's top villain. The turn occurred on the August 21, 1995 edition of Monday Night Raw, where Men on a Mission were to wrestle Smith and Lex Luger, who were then known as The Allied Powers. Luger was not at the event, so Smith convinced Diesel to be his partner. Smith then attacked Diesel during the match and joined King Mabel and Sir Mo in assaulting him. The attack was called the "Royal Plan" and at least for a period it appeared that Smith, Mabel, Mo, and Jim Cornette were going to be aligned in the future. This never came to pass.

The reason for Frazier's sudden removal from the top of the card was never explained, but Kevin Nash (Diesel) implied it had something to do with his wrestling style. Nash said in an interview with Kayfabe Commentaries that Frazier's style was very reckless and he had little regard for the safety of his fellow wrestlers. Nash said that entering the match at SummerSlam, Frazier had already injured "six or eight" of his colleagues in the ring. Nash said that one of the injuries was to one of the Samoans on the roster (Fatu), which he implied was not easy to do and should have raised a red flag. Nash pointed to Frazier's use of a frequently utilized move by wrestlers of comparable size, the sitdown splash. Most wrestlers who perform this move, like Frazier, tend to be super heavyweights, such as the aforementioned Fatu (who adopted the move later in his career), Yokozuna, and Earthquake. These wrestlers usually do so without incident, as they perform it in such a manner that very little of their body weight actually comes in contact with the opponent's body, which usually results in the wrestler landing on the opponent's chest. Frazier kicked his legs out while performing the move and thus did not allow himself to stop before impact. Nash said that this caused all of Frazier's 500-plus pound mass to shift to his rear end and thus he would drop onto the opponent full force. With this in mind Nash told Frazier to leave the move out of the match, knowing full well the potential for serious injury. Frazier disregarded the request and performed the sitdown splash on Nash anyway, crashing into his lower back with enough force to cause Nash's spine to compress and his core muscles to stretch out. Nash later was diagnosed with a badly strained abdomen that affected his performance the rest of the match, as he could barely feel his legs, and he believed that he had suffered some sort of permanent damage to his spine. Backstage, Nash recounted that a furious Vince McMahon was ready to fire Frazier immediately after the match and was about to hand him his release papers, but Nash stepped in and convinced McMahon otherwise as he did not feel Frazier should lose his job over the incident.

Although he was no longer the main villain in the WWF, the company moved Frazier to another high-profile feud involving The Undertaker. The rivalry started after Mabel helped Yokozuna, another wrestler managed by Jim Cornette, attack a downed Undertaker. During the course of the attack, Mabel was to hit a series of leg drops on the fallen Undertaker. He once again found himself in trouble due to his inability to perform the move correctly. Instead of landing his leg across the Undertaker's chest as in a normal leg drop, Mabel repeatedly struck Undertaker in the face; this resulted in Undertaker suffering a legitimate fracture of his orbital bone, which put him out of action for two months.^[14][15] Although King Mabel was to wrestle The Undertaker once he returned, Frazier's days in the WWF were numbered after this incident as the company was not happy with him injuring yet another of its top stars. The Undertaker returned wearing a Phantom of the Opera-style mask and, a month later, defeated King Mabel in a Casket match at In Your House 5: Seasons Beatings.^[16] After this match, Frazier's push came to an end and within several weeks both he and Horne were fired. His last three matches were on the New Year's Day edition of Raw when he was buried in an eight-second loss to Diesel, on the January 6, 1996 edition of WWF Superstars when he lost a rematch to The Undertaker in a casket match, and in the 1996 Royal Rumble match where he was the third wrestler eliminated by his former rival Yokozuna.

Ministry of Darkness and Corporate Ministry (1998–1999)

On July 6, 1998, Mabel made a one-night-only surprise return to the WWF to unsuccessfully challenge the new King of the Ring, Ken Shamrock.^[20] On Sunday January 24, 1999, Frazier made his full-time return, first appearing at the pre-show for the Royal Rumble, then on the show itself, where he was kidnapped by The Undertaker, his Acolytes (Bradshaw and Faarooq) and Mideon.^[21] The next night on RAW, he was reintroduced as Viscera,^[4] he began acting as the Ministry of Darkness' enforcer, adopting a gothic look in the process, including white-out contact lenses, a bleached mohawk and a black bodysuit.^[22]

Hardcore Champion and departure (1999–2000)

The Ministry of Darkness would break up in July 1999, and Viscera floated around the mid-card, frequently teaming with fellow former Ministry member Mideon and becoming part of the burgeoning hardcore division, winning the WWF Hardcore Championship on April 2, 2000 at WrestleMania 2000, and losing it minutes later, in the same Battle Royal-style match.^[23] He also feuded with Mark Henry after body splashing Henry's girlfriend, Mae Young in February 2000. He was taken off the WWF main roster in April and was sent to the development territory Memphis Championship Wrestling before he was released from his WWF contract in August 2000.

World's Largest Love Machine (2004–2007)

Viscera in August 2005

Frazier, as Viscera, returned to the former WWF (by then renamed World Wrestling Entertainment) as a surprise in September 2004, attacking former Ministry of Darkness leader, The Undertaker, at the command of former Ministry Acolyte, the WWE Champion John "Bradshaw" Layfield.^[26] After two weeks on SmackDown!, he was moved to the Raw brand.^[27] In his first three months on the Raw brand, Viscera mainly wrestled on Raw's sister show Heat, only making sporadic appearances on Raw.^[4] His first major storyline there started in April 2005, when he aligned with Trish Stratus as part of her feud with Lita and Lita's husband, Kane.^[28] While working together, Viscera and Stratus appeared in a segment in which he attempted to seduce her, only to be rebuffed. Stratus implied he would first need to "take care" of Kane.^[29] That segment began a gimmick change for Viscera, who transformed into "The World's Largest Love Machine". After losing to Kane at Backlash, he injured Stratus with his Big Splash finishing move, angry about her constant belittling of him, turning face in the process for the first time since 1995.

Viscera began wrestling in pajamas and making overtly sexual gestures in the ring. He became smitten with Raw ring announcer Lilian Garcia and tried different tactics to seduce her every week.^[30][31] At Vengeance in June, Garcia finally reciprocated, proposing to him in the center of the ring, only to be turned down and left crying in the ring when The Godfather arrived with many of his hos to show Viscera what he would be leaving behind if he got married.^[32] At the Royal Rumble, Viscera competed in the Royal Rumble match where he was eliminated by Carlito and Chris Masters. At WrestleMania 22, Viscera won an 18-man interpromotional battle royal. Viscera then teamed with Val Venis to form V–Squared. They teamed together for nearly nine months, mainly on Heat. They challenged for the World Tag Team Championship on several occasions, but never held the title.^[33] When Venis was sidelined with a legitimate injury in April 2006, Viscera returned to singles wrestling. He attempted to reconcile with Garcia, but was interrupted and attacked by Umaga during his proposal.^[34] Two weeks later, when Garcia was legitimately and accidentally knocked from the ring apron by Charlie Haas and sprained her wrist,^[35] the incident was worked into a storyline of Haas and Viscera fighting over Garcia.^[36] After Lillian declared she wanted to be just friends, Haas seemingly raked Viscera in the eye, with Viscera feigning to accidentally Samoan slam Lillian. After Viscera gave Lillian the Samoan slam, both men laughed about the incident, in the process turning Viscera heel once again.^[37] The team split up when Haas reunited with Shelton Benjamin to reform The World's Greatest Tag Team.

Big Daddy V (2007–2008)

On June 17, 2007, Viscera was sent from the Raw brand to ECW in the supplemental section of WWE's draft.^[38] Three weeks later, he debuted on ECW, repackaged as Big Daddy V, a "hired muscle" character in the employ of Matt Striker, arriving just in time to help Striker in his rivalry with The Boogeyman.^[39] After disposing of The Boogeyman, Big Daddy V defeated Tommy Dreamer in the ECW brand's Elimination Chase to become the number one contender for the ECW Championship at No Mercy.^[40] There, he lost to CM Punk by disqualification, when Striker interfered in the match.^[41] He then feuded with SmackDown's Kane. At Survivor Series, Big Daddy V competed in a Survivor Series elimination match where his team lost. At Armageddon, Big Daddy V and Mark Henry defeated CM Punk and Kane. Big Daddy V was an entrant at the 2008 Royal Rumble where he was eliminated by Triple H. His last PPV appearance was when he participated in the SmackDown Elimination Chamber match at No Way Out, but was eliminated first. He wrestled his last WWE match on March 11, 2008, for an episode of ECW, losing to CM Punk in a Money in the Bank qualifying match. In the 2008 WWE Supplemental Draft, he was drafted to the SmackDown brand.^[42] Frazier was released from his WWE contract on August 8, 2008.^[43]
