1-Jerome LeBanner- JLB would easily make any Top 3 ranking in this category. The list is long of his one hit KOs . We’ve all seen the doctors rush the ring after he slammed an opponent with a hard hit. We know the reason he has the most wins after getting knocked down is because with JLB all it takes is one clean hit and the fight is over.

2-Branko Cikatic- Branko has the record for KOs in a row (4) in the K-1 Grand Prix. For a fighter with marginal skills to win the Grand Prix at age 38 with all KOs, the man had to hit hard. Even when Ernesto Hoost met an even older Branko in a revenge match, Mr. Perfect got knocked out cold.

3-Ray Sefo- For a guy nicknamed Sugarfoot, his hands are pretty terrifying in the sport. Sefo is a very good gatekeeper for the K-1. Any new talent thinking of breaking into the K-1 has to worry about simply making it to the end of a bout against Ray. The K-1 has even openly shown dismay at Sefo for ending fights too quickly.

4-Mark Hunt- Never a dull moment in a Mark Hunt fight. Not only can the man soak up damage like a champ, he can also dish it out. One good example of a typical Mark Hunt fight is the 2002 fight against Stefan Leko. Leko was ahead on points and in the final round Mark made him do the puppet dance. A power puncher like Mark can (and did) have a few sub par rounds and came out on top thanks to a few high impact seconds.

5-Francisco Filho- After slapping the K-1 Grand Prix champion unconscious in his first pro fight, Filho went on to secure all his first 7 wins by KO. Filho commanded enormous respect for his power. 

6-Frans Botha- Despite the list of losses, Botha got a lot of respect in the ring for his ability to hit hard. His opponents either ran or blocked. No one wanted to trade hit for hit.

7-Mike Bernardo- Often considered a lesser boxer in the kickboxing ring, Bernardo did what better boxers couldn’t do, KO top ranked kickboxers.

8-Bob Sapp- Without even a thimble of technique, Sapp managed to become on of the hardest hitters in the K-1. My theory is that his swatting style of punching was so alien to fighters that they couldn’t defend properly, and his size made up for the unconventional swing.

9-Peter Aerts- One measure of a power puncher is the man who drops his opponents with punchers to the body. LeBanner, Greco and Bernardo can all give testimony to Peter’s body blows.

10-Mirko Filipovic- Most will agree that Filipovic scored most of his KOs from a beatdown frenzy or a high kick. However, he did break Sapp’s orbital bone with a single punch. That is impact.
