Anthony Joshua will face the American YouTuber in an eight-round match which will be streamed in real-time on the streaming platform.
Briton Joshua declared he will "overwhelm entirely" the American and "break" his opponent as the combatants confronted each other to publicize next month's boxing match.
Ex twice world boxing king Anthony Joshua faces YouTuber-turned-boxer Jake Paul - in what is, theoretically, a massive uneven pairing - at Miami's venue on 19 December.
Fighter's Attitude
"I will break his face and break his body up. I aim to demonstrate I'm the better fighter," the British boxer, 35, said.
"I plan to overwhelm him. That's how fighters think.
"I'm going to really want to hurt him. That's what I want to do."
Respectful Interaction
In spite of those words, a calm Anthony Joshua and social media star Paul - normally famous for his theatrics - were respectful and maintained decorum with each other.
Paul instead criticized ex Joshua rival Francis Ngannou and described him as "ridiculous" after Ngannou declined a bout proposal.
Taking Aim at Fury
Anthony Joshua, at the same time, targeted British opponent Fury - and refused a £1m bet 'Tyson Fury' claims he will make on a Paul victory.
"[Paul] is better than Tyson Fury - he's present here," Joshua stated.
"I give him credit for that."
Legitimate Fighter
Despite declaring he will damage his opponent, Joshua refused to talk badly about his rival's boxing ability.
"Jake Paul is a serious fighter," he remarked.
Paul's Background
Jake Paul - who originally gained popularity on the Disney Channel - has mainly boxed mixed martial artists or faded names since entering professional boxing.
He was defeated by British fighter Fury in last year.
Financial Success
Still, the inexperienced fighter is still one of boxing's largest money-making draws, consistently making huge financial rewards.
Prediction and Confidence
The 28 year old forecast a KO victory in round four or five and asserted he would derail the much-anticipated Joshua–Fury fight, which is reportedly being planned for two years from now.
"It's going to be myself against Tyson Fury in the coming year," Jake Paul declared.
Physical Difference
As the two fighters met for the traditional face-off, with their height and weight contrast evident, it drove home just how improbable this complete situation is - and how amazing it is that the fight is truly going ahead.
