Anthony Joshua is set to fight Jake Paul in an eight round contest which will be shown in real-time on the streaming platform.
Briton Joshua declared he will "overwhelm entirely" the American and "overpower" the American as the pair came face-to-face to promote the upcoming heavyweight fight.
Former twice unified heavyweight champion Joshua battles social media star turned fighter Jake Paul - in what is, on paper, a massive disparity - at Miami's arena on 19 December.
Boxer's Mentality
"I will break his face and hurt his body. I'm here to prove I'm the better fighter," the British boxer, 35 years old, declared.
"I plan to overwhelm him. That's a fighter's mentality.
"I will really want to hurt him. That's what I want to do."
Respectful Exchange
In spite of those words, a relaxed Anthony Joshua and internet personality Paul - typically known for his theatrics - exchanged pleasantries and kept it respectful with each other.
Jake Paul rather targeted ex Joshua rival Francis Ngannou and described him as "ridiculous" after the Cameroonian turned down a fight offer.
Taking Aim at Fury
Anthony Joshua, at the same time, took aim at British opponent Tyson Fury - and refused a million-pound wager 'Tyson Fury' says he will place on a Paul victory.
"Jake Paul is better than Fury - he's actually sitting here," the boxer commented.
"I acknowledge that."
Legitimate Fighter
In spite of stating he plans to punish Paul, Anthony Joshua chose not to speak negatively about his rival's fighting skills.
"Jake Paul is a credible opponent," he remarked.
Paul's History
Paul - who initially became famous on the Disney Channel - has mainly fought mixed martial artists or past-their-prime fighters since becoming pro.
He lost to Briton Tommy Fury in last year.
Commercial Attraction
Still, the relative newcomer remains one of the sport's greatest financial successes, consistently making substantial financial rewards.
Forecast and Belief
The 28-year-old anticipated a knockout win in rounds four or five and stated he would stop the much-anticipated match between Joshua and Fury, which is apparently in the works for two years from now.
"It will be me versus Tyson Fury next year," Jake Paul said.
Size Disparity
As Joshua and Paul participated in the traditional confrontation, with their height and weight contrast evident, it emphasized just how unlikely this whole event is - and how amazing it is that the match is truly happening.
