#1 Jon Jones
Jon Jones is arguably the best fighter ever to step foot in the UFC’s Octagon. After capturing the belt and becoming the organisation’s youngest ever champion at the tender age of 23, Jones went on an absolute tear at 205lbs, defeating a murderers’ row of contenders including current light heavyweight and heavyweight champion, Daniel Cormier, amongst many others.
From Shogun and Rampage Jackson to Lyoto Machida and Vitor Belfort, Jones ran through anybody and everybody the match-makers put in front of him, and he made it look oh so easy.

Only Alexander Gustaffson managed to trouble him, and their iconic fight, which Jones nabbed via split-decision, went down as an instant classic and highlighted the heart and determination Greg Jackson’s star pupil possesses, to go with his incredible athletic abilities.
But for Jones’ troubles outside the cage, the New Yorker would probably still be the king of the light heavyweight division, but unfortunately a string of drug offences – two for steroids and one for cocaine – have left his career in tatters, and we may never know how impressive his legacy truly could’ve been if only he’d managed to stay on the right side of USADA.
Although others may have more title defences, ‘Bones’ is arguably the best champion in UFC history simply because of the quality of the opponents he faced and the way in which he mercilessly disposed of them.
