Collection: Ken Shamrock The World's Most Dangerous Man

In the late 1990s, an unmistakable and thundering guitar riff marked the coming of The World’s Most Dangerous Man, Ken Shamrock. The memorable entrance theme signaled an unbridled intensity that Shamrock brought to the squared circle — a competitive nature forged through his mixed martial arts discipline and WWE career.

The leader of the Lion’s Den training camp for fighters made a name for himself in the early days of UFC. Shamrock’s rivalry with MMA legend Royce Gracie established him as one of the organizations first and biggest stars. In 1995, Shamrock became the UFC’s first champion outside of tournament competition, winning the Superfight Championship before competitors were divided by weight class. Establishing a hall of fame career in UFC, The World’s Most Dangerous Man decided to move on to a then-grander stage in 1997 by joining WWE.

Making his first appearance at ringside in February 1997, Shamrock soon became involved in the heated rivalry between Bret “Hit Man” Hart and “Stone Cold” Steve Austin. At WrestleMania 13, The Excellence of Execution and The Texas Rattlesnake engaged in a No Disqualification Submission Match with Shamrock as the special referee in a bout that gave the WWE Universe their first glimpse of The World's Most Dangerous Man's physical nature.
