A childhood fan of Big Daddy, Atkins began wrestling for All Star Wrestling in 1993, adopting the ringname James Mason, after the film actor of the same name at the behest of ring announcerJohn Harris. Early in his career, he also wrestled for Welsh promoter Orig Williams under the name Jesse James. In 1995, Mason was named by All Star as "Young Wrestler Of 1995" and was interviewed by Simon Garfield for his book The Wrestling. In early 1996, he won a tournament promoted by Rumble Promotions for the World Middleweight Title left vacant by Danny Collins when he moved up the weights. Mason lost the title to Mal Sanders a month later. Mason, Dean Allmark and Doug Williams all faced and lost to Kendo Nagasaki in a December 2001four way match at the Victoria Hall in Hanley, promoted as Nagasaki's retirement match. Mason was the final opponent eliminated by Nagasaki to win the match. In 2002, he and Sanders feuded for the British Middleweight Title in TWA with the belt passing back and forth between them.
