ONE Championship is a premiere martial arts organization (the largest in the world, in fact) simply because it constantly produces moments that get fans out of their seats. Many of its finishes are so unbelievable that you have to call your friends that instant to make sure they see it too. Almost every ONE Championship event has some kind of finish that you've never seen before.Just look at this body jab knockout by Guto Inocente and tell us if you've ever seen something like it: View this post on Instagram Instagram PostYou don't see that all the time. Today, we talk about one thing that most people consider the greatest equalizer in combat sports: knockout power. In particular, punching power.It's what makes professional fighting so exciting and different from all other sports - a well-placed power punch can turn a whole fight around at any moment. A fighter can be losing 90% of a fight, but with just one perfectly timed power punch, he can win. The LA Lakers couldn't be down by 20 points with a second left in the game and rely on LeBron James for a layup to win. It just doesn't happen in those sports.

We're not going to talk about knockout artists who are known for their kicks, knees or elbows (although ONE Championship has a lot of those as well). We will focus on those fighters with cinder blocks for hands.With that said, here are 5 of the hardest punchers in ONE Championship today.#5. ONE Championship bantamweight Muay Thai world champion Nong-O GaiyanghadaoONE bantamweight Muay Thai world champion, Nong-O Gainyanhadao, is the perfect combination of clinical precision and earth-rattling power. He's not just dangerous with his hands, Nong-O can also put you away with his kicks, knees and elbows if he needs to.As of late, however, we've seen the Evolve MMA fighter put his opponents away with his nuclear right hand. What's scary about Nong-O is that he's absolutely precise when he hits you.Just look at how Nong-O uppercut penetrated through Felipe Lobo's tight guard: View this post on Instagram Instagram PostNong-O is like a surgeon with his punches. He'll snake his hands through your guard until he finds the contact point and lands the finishing blow. The best way to describe his fists is homing nuclear missiles. They'll find you and once they do, expect catastrophic results.
