Fedor Emelianenko

Fedor Emelianenko dominated Pride FC with a 27-fight unbeaten streak from 2000 to 2010, a run that outperforms #8 Demetrious Johnson's 11 consecutive title defenses in longevity. His 40-6 record includes 16 wins over current or former champions, with a 72% finish rate that is 20% higher than the average heavyweight legend.
