[4][2] 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.

[7] At WrestleMania X, Men on a Mission defeated the WWF Tag Team champions, The Quebecers, by countout, but did not win the belts.

[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.

[10] In March 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.

[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.

[12] After his victory King Mabel became the top heel in the company and challenged WWF Champion Diesel at August's SummerSlam.

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.

The attack was called the "Royal Plan" and at least for a period it appeared that Smith, King Mabel, Sir Mo, and Jim Cornette were going to be aligned in the future; this never came to pass.

[14][15] 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.

[20] On July 6, 1998, Mabel made a one-night-only surprise (taped June 30) return to the WWF to unsuccessfully challenge the new King of the Ring, Ken Shamrock.

He eliminated five competitors; Droz, Steve Blackman, Dan Severn, Tiger Ali Singh and The Blue Meanie.

[22] The next night on Raw is War, 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.

In March 2003, Frazier, as Nelson Knight, made a surprise appearance at a monthly Total Nonstop Action Wrestling pay-per-view, at the side of Ron Killings.

After losing to Kane at Backlash on May 1, 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.

[44] After leaving WWE for the final time, Frazier joined the National Wrestling Alliance, as King V. On October 3, 2008, defeated Rob Conway in Tulsa, Oklahoma.

The next night in Corpus Christi, Texas, King V defeated Andy Dalton and Joey Spector in a handicap match.

Frazier performed at three Family Wrestling Entertainment shows in 2012 as Big Daddy V, first defeating Malta the Damager in a tables match in February.

Frazier's final match, as Big Daddy V, was a win over René Duprée on Qatar Pro Wrestling's inaugural tour, on October 5, 2013.

In an interview with Kayfabe Commentaries, Kevin Nash implied that his decline from the top of the card was due to his wrestling style.

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.

Although King Mabel was to wrestle The Undertaker once he returned, Frazier's days in the WWF were numbered after this incident as he had injured yet another of the company's top stars.

His wife Cassandra stated that he had been planning on being more healthy before his death, as doctors told him his blood pressure was way too high, and it was affecting his type 2 diabetes.

He reacted by removing salt and sugar from his diet, which resulted in him losing over 100 pounds, with his high blood pressure dropping to a healthy level.

McDevitt called Viscera's death "tragic", but added: "It's ridiculous that someone can ... try to blame someone because a gentleman with a weight problem died of a heart attack in the shower eight years [sic] after he last performed.

"[54] The lawsuit was dismissed by US District Judge Vanessa Lynne Bryant, who ruled that they failed to show that his death was linked to CTE.
