MIDDLEWEIGHT menace Gennady Golovkin is causing havoc each time he steps through the ropes to risk his WBA and IBO belts.
He's back on BoxNation this weekend as he bids for his 20th consecutive knockout win, when American Willie Monroe challenges him at the Inglewood Forum.
His fan base is growing all the time, and there is even talk that next year could see a catchweight contest against the world's top boxer, Floyd Mayweather Jr.
But why are his performances the talk of boxing? BoxNation looks back on six nights to remember so far for the Kazakh KO King.
21/2/15 MARTIN MURRAY TKO 11
St. Helens' Murray was perhaps too brave for his own good, but took a shelling from the world's most feared 160lb boxer despite a show of defiance. 'Triple G' dropped Murray in round four and ten and brought the curtain down on the show in the penultimate session against a challenger who is one of the world's best and may still win a world title.
26/7/14 DANIEL GEALE TKO 3
Poor Geale had to suffer for four minutes in round one because of a timekeeper's blunder. The Aussie was supposed to be GGG's stiffest test but was left feeling sorry for himself after being cut and hurt in round two. A sledgehammer right dropped him in round three and although Geale beat the count his legs looked like they belonged to a Saturday night drunk and Michael Ortega quickly halted the carnage.
29/6/13 MATTHEW MACKLIN KO 3
Some fans were labelling Golovkin "the best boxer nobody knows," but the win over Birmingham's popular two-time world title challenger built his profile massively. Macklin pushed Felix Sturm and Sergio Martinez in his previous world championship challenges. He had no answer and the left hook to the body that knocked out the Briton is shown on many highlight reels. 'Without a shadow of a doubt, he's definitely the best kid I've ever fought,' said Macklin.
19/1/13 GABRIEL ROSADO TKO 7
Philadelphia's Rosado is one of boxing's blue collar tough men and wasn't scared to go toe-to-toe with Golovkin. Nonetheless it was frightening to watch him take a fearful hiding and have his face left a grotesque mask of bumps and bruises. Steve Smoger should have stepped in earlier, but refused to stop the beatdown until Rosado's trainer Billy Briscoe leapt onto the apron with the white towel pleading surrender. Rosado said: "I just want to say this guy is strong as hell."
1/9/12 GRZEGORZ PROSKA TKO 5
This WBA middleweight title defence in an upstate New York casino was one of his most significant wins. The Polish challenger was nothing special, going over three times. But this fight was Golovkin's HBO debut and they have been coming back for more ever since.
19/12/11 LAJUAN SIMON KO 1
BoxNation had only been going for two months when the 'Channel of Champions' gave British fans first glimpse of this special talent. The fight took place in the ballroom of a Dusseldorf hotel after being slated for the undercard the following evening of Wladimir's Klitschko scrapped fight against Jean Marc Mormeck. There were barely 200 fans present for the hastily arranged card and they didn't have to wait long for action. The American rushed in and was bombed from a counter right hand in just 137 seconds.
