Royce Gracie gained fame for his domination of The UFC. He became known for beating opponents much larger than he was, and between 1993 and 1994, he was the tournament champion of UFC1, UFC 2, and UFC 4. Gracie also fought to a draw with Ken Shamrock in Superfight at UFC 5. Royce Gracie popularized Brazilian Jiu-JItsu and revolutionized modern era martial arts. He holds the most submission victories in UFC history with 11, which he earned between UFC 1 and UFC 4.
In his debut match, Royce defeated veteran boxer Art Jimmerson. He took him to the ground using a baiana (morote-gari or double-leg takedown) and obtained the dominant mount position. Mounted and with only one free arm and zero idea of what to expect, Jimmerson conceded defeat and tapped out.
