25. Quinton “Rampage” Jackson (38-13)
Rampage was a fan favorite. Fans expected knockouts when Quinton stepped into the octagon with his signature oversized bulldog metal chain around his neck, hollowing through the arena. Rampage is the only fighter best known for his KO’s by slamming. Rampages’ knockout via slam against Ricardo Arona is still regarded as one of the best knockouts in MMA history.
