5. Royce Gracie
UFC 1 “The Beginning”
Nov. 12, 1993 | Denver
At the event that started it all, Gracie fought three times, defeating Art Jimmerson, Ken Shamrock and Gerard Gordeau by submission to win the UFC 1 tournament. It marked the debut not only of perhaps the most influential figure in MMA history but also the first appearance of Brazilian jiu-jitsu on a major stage.
Gracie remained undefeated inside the Octagon until 2006, when he lost to Matt Hughes by first-round technical knockout at UFC 60. Rumors of a return to fighting persisted until November 2013, when Gracie announced his retirement prior to UFC 167 the week the company turned 20.
