Anthony Joshua prepares to battle the American YouTuber in an eight round match which will be broadcast live on the streaming platform.
Briton Joshua said he will "overwhelm entirely" Jake Paul and "break" the American as the two fighters confronted each other to build hype for the upcoming bout.
Ex two time unified title holder Anthony Joshua battles YouTuber-turned-boxer Paul - in what is, by the numbers, a massive uneven pairing - at Miami arena on 19 December.
Fighter's Mindset
"I will break his face and break his body up. I aim to demonstrate I'm the better fighter," Joshua, 35, declared.
"I will dominate him completely. That's a fighter's mentality.
"I'm going to genuinely try to injure him. That's what I want to do."
Civil Interaction
Despite those words, a relaxed Joshua and social media star Paul - usually known for his theatrics - exchanged pleasantries and remained civil with each other.
Jake Paul instead criticized ex Joshua rival Francis Ngannou and called him "a joke" after Ngannou rejected a fight offer.
Taking Aim at Tyson Fury
Anthony Joshua, meanwhile, took aim at UK opponent Fury - and declined a million-pound wager 'The Gypsy King' says he will place on a victory for Paul.
"[Paul] is better than Tyson Fury - he's present here," the boxer stated.
"I respect him for that."
Serious Fighter
In spite of saying he intends to punish Paul, Joshua declined to speak negatively about his opponent's pugilistic talent.
"Jake is a credible opponent," he stated.
Jake Paul's Background
Jake Paul - who originally gained popularity on the Disney Channel - has primarily fought MMA fighters or faded names since becoming pro.
He lost to British fighter Tommy Fury in last year.
Financial Success
Still, the novice remains one of boxing's largest financial successes, regularly earning huge earnings.
Prediction and Confidence
The 28-year-old predicted a stoppage in round four or five and claimed he would prevent the much-anticipated match between Joshua and Fury, which is allegedly in the works for two years from now.
"It will be me versus Tyson Fury in the coming year," Jake Paul declared.
Physical Disparity
As Joshua and Paul engaged in the usual face-off, with their physical disparity clearly visible, it drove home just how unlikely this complete situation is - and how astonishing it is that the bout is really happening.
