Few trilogies have been quite as evenly matched as the one between Johnson and Moraes.
In the first encounter between the pair in 2021, it was Moraes that turned away the challenge of “Mighty Mouse,” who had reeled off three highly impressive victories inside the ONE. circle since his high-profile to the ONE two years earlier.
“Mikinho” handed the American legend his first career knockout via with a devastating grounded knee in the second round to retain the flyweight world title and shock the world.
Following the jaw-dropping end to the first bout, it was clear that fans wanted to see the two superstars tussle again. And the second meeting didn’t disappoint.
Incredibly, Johnson returned the favor when they met in last August, stopping Moraes with a flying knee in the fourth round to claim the ONE flyweight world title.
All debate of who the better man is will be settled on May 5, and fans should be prepared for an all-out war to find the answer.

ONE Fight Night 10 is a landmark event for ONE Championship.

The world be watching on May 5, and the action that will go down in this headlining bout will leave no doubt that ONE is a global force that can produce fights that rival any combat sports organization on earth.
3. It could be the last time we see the GOAT

One of the most notable elements in the build-up to ONE Fight Night 10 has been the speculation surrounding the future of “Mighty Mouse.”
The 13-time flyweight world champion is widely regarded as the greatest MMA practitioner of all time, and his decorated run in North America and Asia is stuff of legend.
Johnson himself has been fanning the flames, as he admits he’s been mulling things over with regards to hanging up the gloves.
“I feel sometimes that training camps take me away from that. Which, it’s my job. But, you know, there’s part of me, it’s like, ‘How much more? How much more?’” he said.
“And I think after this fight’s done, I’ll be more transparent of why I say this might be my last fight or this horse’s last ride or whatever. But I think to like divulge it all and stuff right now, it just wouldn’t be the right time.”
