Conor McGregor has given UFC fans an explosive career full of record-setting highs that aren't likely to be matched in the foreseeable future.
Despite the highs, there have also been a series of lows, alongside periods spent away from the sport, that have seen Notorious returning to the Octagon as an outsider in recent years.
Even with his defeat to Khabib Nurmagomedov meaning he was unable to regain the lightweight title in 2018, McGregor remains one of UFC's most high profile stars.
With his latest victory against Donald “ Cowboy ” Cerrone at UFC 246, McGregor added a new record to his collection that will only enhance his reputation as he begins his return to the top.
Below are three records that are certainly going to take some beating.
KO victory across three weight classes
Probably the most impressive record of the lot, McGregor's 40-second victory over Cerrone at UFC 246 means that the Irishman has now scored knockout victories at featherweight, lightweight and welterweight.
McGregor was at his brutal best against the American and, in forcing the stoppage, became the first man to score knockout victories in three separate weight classes.
Fastest KO victory in a title fight
Originally billed as the fastest KO victory full stop, McGregor took just 13 seconds to dismantle Jose Aldo at UFC 194. The featherweight title bout had barely begun when McGregor beat Aldo to the punch with a powerful left hook that sent his opponent straight to the canvas.
Jorge Masvidal’s five-second knockout against Ben Askren is now recognised as the new fastest knockout in UFC but it is unlikely that we'll see a title bout end as quickly anytime soon.
Highest-selling UFC pay-per-views
There is something about McGregor that fans can't get enough of, love him or hate him, everyone is tuning in to see his fights. The former two-division champion holds all three spots at the top of the highest pay-per-views chart.
At number one on the chart is McGregor's lightweight championship bout against Kahbib which drew 2.4 million buys. Spots two and three feature McGregor's epic bouts against Nate Diaz at UFC 202 and 196 which drew 1.6 million and 1.317 million buys respectively.
Whatever you think of Conor McGregor, these records only confirm what an asset the Irishman has been to UFC in recent years. Despite the controversies, these records could see McGregor holding his place as one of the most high profile fighters for years to come.
