Bobby Horne, known to wrestling fans as Sir Mo from the popular 1990s WWE tag team Men on a Mission, has died at 58. The news was confirmed on Facebook by Book Pro Wrestlers, posting that he passed away on October 19, 2025, at a hospital in Texas.
Horne had been facing severe health complications in recent weeks. He was hospitalized with pneumonia and a severe blood infection, requiring intensive care treatment. His health struggles were not new, as he underwent a kidney transplant in 2018 and battled COVID-19 in 2022, both of which had taken a toll on his body over the years.
Born on April 13, 1967, Horne began his professional wrestling career in 1991. He signed with WWE in 1993, where he was paired with Nelson Frazier Jr., who performed under the ring names Mabel, Viscera, and Big Daddy V. Together, they formed Men on a Mission, one of the most colorful and entertaining tag teams of the WWE’s New Generation era. The duo was managed by Oscar, whose rapping entrance routines became a signature part of the team’s appeal.
Men on a Mission achieved their greatest success on March 29, 1994, when they defeated The Quebecers to capture the WWE Tag Team Championship at a live event in England. The championship reign was brief, however, as they lost the titles back to The Quebecers just two days later in a rematch. Despite the short duration, the victory marked a significant milestone in both wrestlers’ careers and cemented their place in WWE history.
The team’s trajectory changed in 1995 when they turned heel, abandoning their positive, fan-friendly persona. That same year, Mabel won the King of the Ring tournament, one of WWE’s premier annual events. Following this victory, Horne transitioned into a supporting role, becoming known as Sir Mo and serving as Mabel’s manager and on-screen ally during this new phase of their partnership.
Horne left WWE in 1996 and continued his wrestling career on the independent circuit, where he remained active for several years. Professional wrestling’s independent scene provides opportunities for performers to work outside major promotions, often allowing them to maintain connections with fans and continue doing what they love in a more intimate setting.
Following news of his passing, tributes poured in from the wrestling community. Former WWE star Leilani Kai shared a heartfelt message on Facebook, remembering Horne from their time traveling together with WWE in the mid-1990s and later working together on the Carolina independent circuit. “He was always kind to me, always smiling, joking around, and treating everyone with respect,” Kai wrote, adding that Horne “had a way of making you feel welcome” during the often challenging life on the road.
Kai’s tribute emphasized Horne’s character both inside and outside the ring. She noted that he was “just as genuine outside the spotlight as he was under it” and that he loved the business, the fans, and giving back to wrestling. According to Kai, “Bobby had that special kind of warmth that reminded you wrestling isn’t just about what happens in the ring, it’s about the people and memories that come with it.”
The wrestling community has experienced numerous losses over the years, with performers often facing significant health challenges due to the physical demands of the profession. The grueling schedule, frequent travel, and physical toll of performing can contribute to long-term health issues that affect wrestlers well after their in-ring careers have ended.
Horne’s tag team partner, Nelson Frazier Jr., preceded him in death, passing away in February 2014. Frazier had continued wrestling for WWE under various personas after Men on a Mission disbanded, including notable runs as Viscera and later as Big Daddy V, before his own health issues led to his untimely death.
Men on a Mission remains a memorable part of WWE history, representing an era when the company was transitioning from the larger-than-life characters of the 1980s to a new generation of performers. Their high-energy performances, distinctive appearance, and positive messaging made them fan favorites, particularly among younger audiences during their initial run.
The tag team division has long been a crucial component of professional wrestling, providing opportunities for compelling storylines and allowing performers to develop chemistry and skills that serve them throughout their careers. Teams like Men on a Mission helped define what tag team wrestling could be during a period of significant change in the industry.
Horne’s legacy extends beyond championship victories to the impact he had on fellow performers and fans who remember him for his kindness and professionalism. In an industry known for its competitive nature and demanding lifestyle, those who prioritize treating others with respect and maintaining genuine connections often leave the most lasting impressions on their peers.
