 The "King's Road" style was in large part derived from American wrestling, particularly the style of top wrestlers in the National Wrestling Alliance, such as Dory Funk, Jr., Terry Funk, and Harley Race, all of whom wrestled for Baba in Japan.As such, "King's Road" placed a heavy emphasis on working of holds, brawling, and the storytelling elements of professional wrestling.Throughout the 1990s, three individual styles — shoot style, lucha libre, and Hardcore — were the main divisions of independent promotions, but as a result of the "borderless" trend of the first decade of the 21st century to have interpromotional matches, the line between rules among major-league promotions and independents has for the most part been blurred to standardization.
