Anthony Joshua prepares to battle Jake Paul in an eight-bout match which will be streamed in real-time on the streaming platform.
Briton Joshua declared he will "dominate completely" the American and "overpower" his opponent as the two fighters came face-to-face to publicize next month's heavyweight fight.
Former two-time world heavyweight champion Joshua meets YouTuber-turned-boxer Jake Paul - in what is, on paper, a huge disparity - at Miami's venue on 19 December.
Fighter's Attitude
"I'm going to injure his face and damage his physique. My goal is to show I'm the better fighter," Joshua, 35, declared.
"I'll stamp all over him. That's a fighter's mentality.
"I'm going to genuinely try to hurt him. That's my goal."
Respectful Exchange
In spite of these statements, a relaxed Anthony Joshua and internet personality Paul - typically known for his theatrics - exchanged pleasantries and remained civil with each other.
Jake Paul instead attacked ex Joshua opponent Francis Ngannou and described him as "a joke" after Ngannou turned down a match opportunity.
Taking Aim at Fury
Joshua, at the same time, criticized UK rival Fury - and refused a million-pound wager 'Tyson Fury' states he will put on a Paul win.
"Jake Paul outshines Tyson Fury - he's actually sitting here," the boxer stated.
"I give him credit for that."
Legitimate Opponent
Despite declaring he will hurt Jake Paul, Anthony Joshua declined to comment unfavorably about his opponent's boxing ability.
"Jake Paul is a credible opponent," he stated.
Paul's History
Paul - who originally gained popularity on the television network - has mostly fought MMA fighters or declining opponents since entering professional boxing.
He lost to Briton Tommy Fury in last year.
Financial Attraction
However, the inexperienced fighter continues to be one of boxing's largest commercial attractions, regularly earning huge earnings.
Forecast and Confidence
The 28-year-old forecast a stoppage in round four or five and stated he would derail the long-awaited Fury-Joshua bout, which is reportedly in the works for two years from now.
"It will be me versus Tyson Fury next year," Jake Paul stated.
Physical Difference
As Joshua and Paul met for the usual stare-down, with their size difference clearly visible, it drove home just how improbable this complete situation is - and how remarkable it is that the bout is truly happening.
