#4. The rivalry between Bibiano Fernandes and Kevin Belingon makes MMA history (ONE Championship: Century Part 2)
Much like the previous entry, this MMA grudge match wasn't born out of genuine hatred but of sheer competitive spirit. Well, almost. Bibiano 'The Flash' Fernandes' domination of his weight class was only halted by one Kevin 'The Silencer' Belingon. The Filipino striker was the only one to power through the Brazilian jiu-jitsu wizard's grappling pressure to nullify his game.
They split their first two bouts 1-1 with the third dance causing much controversy and drama. In the rubber fight, the Filipino was disqualified after hitting Bibiano with elbows in the back of the head. Though the foul was unintentional, the ending stirred some bitterness between the two high-level fighters.

Facing each other for an unprecedented fourth time, Fernandes and Belingon aimed for a definitive end to their rivalry. Belingon was aggressive as always, but Bibiano upped the grappling attacks and choked his opponent in the second round. The grizzled Brazilian closed out the greatest rivalry in ONE Championship history in an unforgettable grudge match.
#3. Stockton vs. Dublin (UFC 202: Diaz vs. McGregor 2)
Now it's time for some genuine bad blood. The grudge match between MMA megastar Conor McGregor and Stockton's favorite son Nate Diaz was historic in all aspects. This event holds the second-highest MMA pay-per-view buy rate of all time and it's easy to see why.
McGregor had a rocketship strapped to his back until Diaz put the brakes on his ascent to the top. Submitting McGregor in their first fight, Diaz was the perfect foil for the Irishman. His street thug approach to fighting and world-class cardio proved problematic.
The level of anticipation and buzz for the 2nd fight was through the roof. Two larger-than-life characters running it back not for a title, but for sheer disdain for each other. The two delivered a classic slugfest akin to the bloodbaths of the olden days. With McGregor inching out a decision in their second dance, perhaps a third battle is in the future.
