Conor McGregor
Though the Irishman's legacy may have taken a slight hit in recent years - given his various escapades outside of the octagon - there can be no forgetting the path that he once walked.
The 'Notorious' became the first UFC fighter in the company's history to successfully become a champion of two weight divisions at the same time; the first official 'Champ Champ'.
He picked up his first title, the featherweight belt, in 2015 after his iconic knock-out victory over Jose Aldo. The Brazilian hadn't been defeated in over 10 years and yet McGregor was able to get it done within 13 seconds.
After two thrilling bouts with Nate Diaz, which both took place at welterweight, McGregor set his sights on lightweight champion Eddie Alvarez.
He wasn't able to defeat the American in the same emphatic fashion as he did Aldo but, nonetheless, was able to get his hands on the lightweight belt after a brilliant knockout in the third round.
The first ever 'Champ Champ' and a legend of the sport. Remember, 'the double Champ does what the f*** he wants'.

Daniel Cormier
After McGregor, came Cormier. The American, who is now long-retired, became the second fighter to hold two titles simultaneously after his triumph over Stipe Miocic.
Cormier had won the light heavyweight title in May 2015 after beating Anthony Johnson with a rear-naked choke. Jon Jones had been champion originally but was stripped of the title by the UFC after being involved in a hit-and-run.
The American then made four defences of the light heavyweight belt before eventually setting up a colossal fight between himself and his compatriot, Miocic.
It was a gargantuan challenge for Cormier, to take on someone with such physical advantages, but he rose to the occasion and delivered a brutal knockout in the first-round.
He'd go on to make one heavyweight title defence against Derrick Lewis before Miocic returned and secured consecutive wins over Cormier and, essentially, ended his career.
