What is the name of the boxer who portrayed Tommy Gunn in Rocky V?

The boxer who portrayed Tommy Gunn in Rocky V is Tommy Morrison. Morrison was a professional heavyweight boxer whose real ring experience made him a natural choice for Rocky's ambitious young protégé.

Released in 1990, Rocky V follows Rocky Balboa after financial problems force him to return to his old Philadelphia neighborhood. Rocky begins training Tommy Gunn at Mickey Goldmill's former gym, hoping to pass on his knowledge to a talented fighter who lacks discipline and perspective. Morrison's athletic ability gives Gunn convincing fight scenes, while his character's hunger for fame creates the film's central conflict.

Tommy Gunn eventually leaves Rocky for promoter George Washington Duke, believing that a professional team can advance his career faster. Their relationship collapses when Gunn attacks Rocky's friend Paulie and later confronts Rocky outside a bar. Rocky defeats Gunn in a street fight, emphasizing the difference between boxing success and loyalty. Antonio Tarver and Tony Bellew played other boxers in the wider Rocky-related films, but Morrison is Tommy Gunn.
