5 Most Famous UFC Fighters 

#1 Conor McGregor

The Champ Champ.

It's not just the UFC, but MMA, in general, needed someone like Conor McGregor to step up and transform some of the aspects of the sport. The loud-mouthed Irishman just doesn't just like to fight but also relishes selling those fights.

He was a nobody in 2013. Fast forward to 2018 and the man is worth more than $110 Million He is the most searched UFC fighter on google and ranks 18th amongst other sporting personalities for 2018. The staggering rise isn't all about the trash talk though, as the Notorious One has walked the talk for a majority of his career. He was exposed in his first fight against Nate Diaz and most recently against Khabib Nurmagomedov, but look at were his aforementioned rivals are at this moment. Both Khabib and Diaz are richer and more famous than they've ever been.

McGregor is a proven draw who has improved on his PPV figures and gate figures each time he fights in the UFC.

Heck, Mcgregor even managed to get Floyd Mayweather out of retirement for one of the biggest and most profitable boxing matches in history. The former multi-divisional UFC Champion has the unrivaled charisma and the gift of gab which are also coincidently the notable traits of the legendary Muhammad Ali. And yes, McGregor is nowhere close to Ali's level but the Mystic Mac has that 'something' no one else has in MMA.

McGregor is not a just a fighter. He is a businessman. A brand. A billionaire in the making and a future UFC Hall of Famer. You can hate the man but you can't doubt the fact that McGregor is the most popular MMA fighter on the planet.
