Frank Shamrock
Funaki's MMA career began when he founded Pancrase along with Minoru Suzuki. Funaki went on to defeat Bas Rutten, Ken Shamrock, Frank Shamrock, Minoru Suzuki, and Guy Mezger, among others. Frank Shamrock said, "Funaki was like a mad scientist. He took the idea of submissions to an even higher level than the rest of the Japanese contingent. He had this insatiable desire to learn more and push his body harder. And as an entertainer he understood the need to entertain."
