Early career (1991–1993) Horne made his debut in 1991 and soon found himself teaming with
Nelson Frazier in the Carolinas-based
Pro Wrestling Federation. The two were
kayfabe half-brothers in a team known as "
The Harlem Knights" with Horne performing as
Bobby Knight and Frazier performing as Nelson Knight. The
heel team was managed by
George South, who led the young team to two PWF Tag-Team titles over the years. In April 1992, Horne worked two matches for WWF both on
Superstars. One in a tag match with
Jim Brunzell losing to the
Beverly Brothers and losing to
The Mountie. In 1993, The Harlem Knights moved on to the
United States Wrestling Association based out of Memphis without their manager George South. While in the USWA, the team was pushed as the "Monster threat" due to their size and feuded with
Jerry Lawler,
Jeff Jarrett, and other faces. Their work in the PWF and the USWA got them noticed by the
World Wrestling Federation (WWF) and they were signed to a contract in the spring of 1993. The team met with moderate success in the ring but got
over mainly due to Mabel’s unusual size, their fun loving personas, and Oscar’s crowd pleasing raps. Their fun loving personalities were prominently displayed when they appeared at
Survivor Series 1993 dressed up as Doinks (referred to by
color commentator Bobby Heenan as "
Doinks on a Mission)" and teamed up with
The Bushwhackers (also dressed as Doink) in a comedy match. At
Royal Rumble, Mo competed in the 30-man Royal Rumble match where he was eliminated by
Fatu. Their next feud was against the
WWF Tag Team Champions The Quebecers and they even won the titles during a
United Kingdom tour. That summer, Mabel started to wrestle more singles matches, leading to a
King of the Ring win. It wasn't until the early part of 1995 that Men on a Mission started to team again on a regular basis. In April 1995 after another loss, Mabel and Mo attacked
the Smoking Gunns in a fit of anger, then apologized for it later on. When they asked the Gunns to come to the ring to let them apologize, Men on a Mission attacked them once again and then beat up Oscar, turning the duo heel and dropping their rapping manager. After a short feud with the Smoking Gunns, Mabel won the
1995 King of the Ring tournament. He became King Mabel with his trusty sidekick being dubbed
Sir Mo, wrestling royalty. When Mabel became king, the focus shifted from the team to Mabel once more with Sir Mo acting more as a manager and less like an active competitor as Mabel challenged for the WWF Championship. One of the last notable appearances for Men on a Mission was at
In Your House 2 where they beat
Razor Ramon and
Savio Vega. They were also the opponents in the match where
the British Bulldog turned on partner
Diesel. Mo lost to
The Undertaker on Monday Night Raw's November 27, 1995, episode during Mabel's feud with Taker. Mo's last WWF match was a loss to
Marty Jannetty on January 12, 1996, in a house show at the
Montreal Forum making it the last wrestling event at the Forum before it was demolished. Mabel and Mo's last appearance in the WWF together was at the
1996 Royal Rumble, where Mo accompanied Mabel (a Rumble participant) at ringside until he was eliminated by
Yokozuna. Both Mabel and Mo left the WWF in early 1996. He returned to
WWF as Buzz on September 6, 1997, beating a jobber at a
house show in Nashville, Tennessee. While in
PPW, Horne teamed up with "Deon Harlem" to form the tag team "The Regulators". The team beat Derrick King in a Handicap match to win the
PPW Tag Team Title, which they held until the promotion closed down in April 2001. Horne subsequently took a hiatus from wrestling. In 2003, Bobby Horne returned to wrestling under a new gimmick. On December 30, while Mabel was at ringside commentating, manager Paul Wylde appeared and introduced the "Bahamian Heavyweight Champion"
Marly Pride. Wylde started making comments that Mabel was the fattest whale, which Mabel took exception to. When the big man entered the ring, Marley Pride was revealed as his former tag-team partner Mo who attacked him and the two brawled until they were separated by officials. Mo and Mabel had a short feud in
Memphis Wrestling. On March 1, 2006, Horne (as Mo) defeated Bad News at a dark match for
Ohio Valley Wrestling. On April 21, 2007, Mo defeated
Christian York at ISPW in Newton, New Jersey. He then retired from wrestling and went into truck driving. Horne worked as a promoter for New Blood Wrestling in
Dyersburg, Tennessee, from 2006 to 2009.
Late career (2014–2025) In 2014, Horne came out of retirement and defeated Mike King at HLW Heroes and Legends III in Fort Wayne, Indiana. In May 2015, he worked four shows as Sir Mo teaming with
Davey Boy Smith Jr. for Ultimate Championship Wrestling in Nova Scotia, Canada. He returned to the Maritimes in July with partner Lord Deon (Dean Johnson) for three more shows. On July 30, the team – known as MOM2K – won the UCW tag team titles by beating Sidewalk Sam and Homeless Bob in
Halifax, Nova Scotia. From January 2016, Horne ran SOAR Championship Wrestling with his wife Denise Jones in Dallas, Texas. Wrestled his last match on March 7, 2020, in a triple threat against Jimmy McDowell and Johnny Walker which McDowell won for Coastal Championship Wrestling in Coral Springs, Florida. ==Personal life and death==
