The British boxer is set to fight Jake Paul in an eight-bout fight which will be streamed in real-time on the streaming platform.
British boxer Joshua stated he will "stamp all over" the American and "break" the American as the combatants came face-to-face to build hype for next month's heavyweight fight.
Ex two-time world heavyweight champion Anthony Joshua faces YouTuber-turned-boxer Paul - in what is, by the numbers, a mammoth disparity - at Miami's arena on 19 December.
Fighter's Attitude
"I'm going to injure his face and damage his physique. I'm here to prove I'm the better fighter," the British boxer, 35, declared.
"I'll stamp all over him. That's a fighter's mentality.
"I intend to really want to injure him. That's my goal."
Civil Exchange
Despite such comments, a calm Joshua and social media star Jake Paul - normally recognized for his theatrics - exchanged pleasantries and remained civil with each other.
Paul rather criticized ex Joshua's opponent the Cameroonian fighter and described him as "ridiculous" after Ngannou rejected a bout proposal.
Targeting Tyson Fury
Anthony Joshua, at the same time, criticized UK opponent Tyson Fury - and refused a million-pound wager 'Tyson Fury' claims he will make on a victory for Paul.
"Jake Paul is better than Tyson Fury - he showed up," Joshua commented.
"I acknowledge that."
Serious Fighter
Despite declaring he will damage his opponent, Anthony Joshua refused to speak negatively about his opponent's pugilistic talent.
"Jake Paul is a legitimate boxer," he remarked.
Paul's History
Paul - who initially became famous on the television network - has primarily boxed mixed martial artists or declining opponents since entering professional boxing.
He lost to Briton Tommy Fury in last year.
Financial Success
Nevertheless, the novice remains one of the sport's greatest money-making draws, regularly earning substantial financial rewards.
Forecast and Confidence
The 28-year-old predicted a KO victory in rounds four or five and asserted he would stop the highly-expected match between Joshua and Fury, which is apparently being planned for two years from now.
"It will be my match with Fury in the coming year," Paul stated.
Physical Disparity
As the two fighters met for the traditional stare-down, with their height and weight contrast clearly visible, it emphasized just how improbable this complete situation is - and how amazing it is that the bout is actually happening.
