Rocky Balboa is loosely based on this American former professional boxer who fought at heavyweight ans was born in what year
Rocky Balboa Robert "Rocky" Balboa is the title character of the "Rocky" series. The character was created by Sylvester Stallone, who also portrayed him in all seven "Rocky" films. He is depicted as an everyman who started out by going the distance and overcoming obstacles that had occurred in his life and career as a professional boxer. While he is loosely based on Chuck Wepner, a one-time boxer who fought Muhammad Ali and lost on a TKO in the 15th round, the inspiration for the name, iconography and fighting style came from boxing legend Rocky Marciano.
