Wanderlei vs Leben By far most humiliating loss of Wandy's career, left fighting the referee like being woken from a nightmare. All his previous devastating victories and aura of fear was effectively taken by Leben and put in his back pocket. Although credit to Wanderlei his kept going and regained some of his rep but it was never the same after that. Dillashaw vs Garbrandt 1 and 2 Smack talk followed by beatdown twice Ruas vs Otsuka Ruas was sick but still, a sad loss for a guy considered 'Rickson' category of uber legend fighter previously. Hard to really compare but basically a 'God of mma' in Brazil losing to a pro wrestler... Matt Hughes Vs Royce Gracie: All that mystique, legend and sense of invincibility traded for ending up beatdown, facedown. Another one that is hard to watch. Mir vs Noguera 2 Submitting the previously 'HW GOAT BJJ mma fighter' after KOing first time was really taking his rep and adding it to his accolades Ken Shamrock vs Anyone post 2004 I'll always remember you Ken as the World most dangerous man that got me into the sport. But damn, someone should have stopped that man fighting and made him a fortune off of his legacy and fame that he deserved. Any other examples of fights where the fighter essentially had his reputation and aura taken in 1 fight or against 1 opponent.
