Artur Beterbiev is the only World Champion in boxing with a 100 per-cent KO record in their entire professional career.

The Russian hammer has beaten all 13 opponents inside the distance and has become a must-watch fighter for BoxNation viewers.

He returns to the Channel of Champions on Saturday 4th May when he makes the second defence of his IBF World Light-Heavyweight Title against Bosnian Radivoje 'Hot Rod' Kalajdzic in Stockton, California.

Beterbiev’s record for chilling opponents speaks for itself, but who are the KO Kings of world boxing right now? BoxNation pundit Steve Lillis names his dirty dozen wallopers, with part two coming next week:

12) MIGUEL BERCHELT

35-1 (31 KOs)

Miguel Berchelt

Mexico’s WBC Super-Featherweight Champion is back on BoxNation on Saturday 11th May in a rematch with fellow Mexican Francisco Vargas for round two of their first epic encounter.

He is one of boxing’s underrated punchers and only one of his fights have been the distance in almost seven years. He can brawl, bang and, if needed to, box.

11) DAVID LEMIEUX

40-4 (34 KOs)

David Lemieux

We all know that the Canadian can be made to look so ordinary just like Billy Joe Saunders did, but his power is there to see.

He does load up on shots and cute fighters read this, but if you are in range and he lands flush, very few get up.

10) ANTHONY JOSHUA

22-0 (21 KOs)

Anthony Joshua

The IBF, WBA and WBO World Heavyweight Champion carries concussive power. We saw how it helped turn the fight around against Wladimir Klitschko, and there will be times in the future he may well have to depend on it again if he hopes to unify the division.

9) TEOFIMO LOPEZ

13-0 (11 KOs)

Teofimo Lopez

The surefire future Lightweight Champion is likely to rise ever higher in punching charts as he continues his career. BoxNation viewers have watched his progress, and his 44 second blowout of Mason Manard last year was the KO of 2018.

Since then he has hammered good men Diego Magdaleno and Edis Tatli inside the distance. Some might argue he should be higher in power rankings, right now.

8) ERROL SPENCE

25-0 (21 KOs)

Errol Spence

Mikey Garcia took Spence the distance in his last fight, but that was the first time in 12 fights the IBF Welterweight Champion had heard the final bell.

Spence may not have the one punch power to wipe out all-comers, but the tools to wear opponents down with solid body shots and physical power before taking them out.

7) GERVONTA DAVIS

21-0 (20 KOs)

Gervonta Davis

The WBA Super-Featherweight Champion is nicknamed ‘Tank’ and carries artillery force when he lets his fists go. His speed combined with power are a nightmare for opponents.

With a stocky frame, the Baltimore bomber's punching capabilities could also cause damage at Lightweight. Men like Liam Walsh and Jose Pedraza, who had never seemed hurt before, couldn’t take his shots.
