Conor McGregor v Donald Cerrone

The most recent addition on this list, Conor McGregor made a big return after 15 months away from the sport to take on Donald "Cowboy" Cerrone. His last fight before UFC 246 was in October 2018 against Khabib Nurmagomedov in the biggest fight in MMA history.

As you know, McGregor was defeated decisively in a dominant performance from the Russian Lightweight Champion. He admitted in the build to UFC 246 that he was in a bad place in life and was drinking a lot more than he should have.

Against "Cowboy" Cerrone, he cleaned up his act and brought a whole new side to himself. His return was marked with an emphatic 40-second knockout over the veteran Cerrone and mark his return successfully.

#1. vs Jose Aldo - 13 seconds

UFC 194: Aldo vs. McGregor

The first of many Million+ PPV for Conor McGregor, this was one of the main points of his rise to stardom. While his Madison Square Garden performance against Eddie Alvarez can be considered as the culmination, this was a huge pivot to that.

He faced his rival Jose Aldo for the Featherweight title in a highly-anticipated match at the end of 2015. It had been ten years since Aldo had even lost a fight and McGregor took over in a big way, knocking the Brazilian legend out in just 13 seconds.

It was history made and McGregor is unlikely to ever top this personal record of his again.
