Heenan debuted in 1960, initially as a wrestler, but transitioned to a managerial role in the World Wrestling Association. It wasn't until the AWA where he would become known as "The Brain," going on to be considered by many, the greatest manager of all-time. In the 80s and 90s he would work for both WCW and WWE, adding Color Commentator to his resume along the way. Many fans fondly remember his time alongside fellow commentator and friend, Gorilla Monsoon. Heenan was inducted into the WWE Hall of Fame in 2004.
