Ahead of Artur Beterbiev's second defence of his IBF World Light-Heavyweight Title on May 4th, BoxNation count down the 12 hardest hitting fighters on the globe.

Russian wrecking ball Beterbiev is the only World Champion with a 100% knockout ratio, with all 13 of his foes failing to hear the final bell.

Last week, part one of Steve Lillis' Dirty Dozen featured the likes of Gervonta Davis, Anthony Joshua and Miguel Berchelt, who returns to our screens on May 11th.

Read part one here. Read part two below:


33-3-1 (28 KOs)

Kovalev punch

Russia’s WBO Light-Heavyweight ruler cuts an intimidating figure, is very deceptive and has underestimated boxing skills. He lives up to his 'Krusher' nickname by hammering opponents with either fist, and still carries that power despite losses to Andre Ward and Eleider Alvarez.

He was taken the distance in his points winning rematch with Alvarez, but the Colombian seemed fearful of engaging with the puncher.


26-1 (19 KOs)

Murat Gassiev

It remains to be seen whether his power will take him to glory when he steps up to Heavyweight this summer, but at 200lb the former IBF and WBA Champion is a serious cruiser bruiser.

Ola Afolabi only ever sparred with him, but says he’s the hardest puncher he ever came across. That is high praise when you study his CV.
The best example of his raw power came his WBSS semi-final against Yuniel Dorticos, who was hammered to defeat in the 12th round.


13-0 (13-0s)

Beterbiev punch

The IBF Light-Heavyweight Champion stalks opponents and wastes little and although some might question opponents many durable men have lost their senses when he landed.

Former WBA Champion Gabriel Campillo was stopped by Beterbiev and Sergey Kovalev. The Spaniard says Beterbiev hits a lot harder.


38-1-1 (34 KOs)

Golovkin v Canelo

The Kazakh star might be on the downward slope following his two fights with Canelo Alvarez, but he still possesses formidable power.

Whilst one-punch knockout power is not his trademark, Golovkin uses his skill set and angles to beat down opponents before taking them apart.


17-0 (15 KOs)

Naoya Inoue

Many people’s pound-for-pound king as well as punching royalty. He carries sensational one punch KO power. No wonder he is called ‘The Monster’.

What makes it difficult for opponents is the precision and speed he throws shots, making it even worse for those who dare to challenge for his WBA Bantamweight Championship.


40-0-1 (39 KOs)

Wilder v Fury

Tyson Fury said that Wilder is “the biggest puncher in Heavyweight history” after sensationally surviving a chilling final round knockdown against the American in their drawn WBC Title fight.

Forget his technique being wrong and not having the skillset of some Heavyweight whackers. When Wilder hits, fighters stay hit...unless you’re Fury.
