Rickson Gracie is considered one of the greatest Brazilian jiu-jitsu fighters in history. A native of Rio de Janeiro, Brazil, he comes from the legendary fighting Gracie family. Along with brothers Royce, Royler, and Rorion Gracie, and his father Hélio, Rickson Gracie has won countless tournaments and championships. A master at submissions, Rickson has defeated such fighters as Japanese jiu-jitsu champion Yoshinori Nishi, kick boxing champion Bud Smith, Pankration champion Masakatsu Funaki, and Japanese wrestling champion Nobuhiko Takada. In 1980, Rickson became a legend by defeating famed vale tudo fighter Rei Zulu, who had an alleged record of 140-0. Rickson is said to have a record of 410 wins and no defeats. However, this record is not without controversy. Gracie is reported to have been defeated in the early 1990s in Oklahoma City losing to Dr. Ron Tripp in a Sambo tournament. In addition, critics often cite the fact he has failed to face any recent champions or truly credible opponents. Regardless, Rickson Gracie will always be ranked among the great jiu-jitsu practitioners. He just may be the greatest jiu-jitsu fighter in history, only time will tell.
