Anthony Joshua will face the American YouTuber in an eight-bout match which will be broadcast in real-time on the streaming platform.
British boxer Joshua said he will "overwhelm entirely" the American and "overpower" his opponent as the combatants confronted each other to publicize the upcoming boxing match.
Former twice unified heavyweight champion Anthony Joshua faces social media star turned fighter Jake Paul - in what is, on paper, a massive uneven pairing - at Miami's venue on 19 December.
Boxer's Mentality
"I plan to injure his face and break his body up. I aim to demonstrate my superiority," Joshua, 35 years old, said.
"I plan to overwhelm him. That's the boxer's mindset.
"I intend to genuinely try to hurt him. That's my goal."
Civil Interaction
In spite of those words, a composed Anthony Joshua and social media star Jake Paul - typically known for his dramatics - exchanged pleasantries and remained civil with each other.
Jake Paul instead attacked former Joshua opponent Francis Ngannou and called him "not serious" after Ngannou turned down a match opportunity.
Taking Aim at Tyson Fury
Anthony Joshua, meanwhile, targeted UK opponent Fury - and refused a large bet 'Tyson Fury' claims he will make on a Paul victory.
"Jake Paul is superior to Fury - he's present here," the boxer stated.
"I give him credit for that."
Legitimate Fighter
Despite stating he plans to punish Paul, Anthony Joshua chose not to talk badly about his opponent's boxing ability.
"Jake is a serious fighter," he said.
Jake Paul's History
Paul - who initially became famous on the television network - has primarily fought mixed martial artists or faded names since becoming pro.
He lost to British fighter Tommy Fury in last year.
Financial Success
Still, the relative newcomer is still one of the sport's largest money-making draws, frequently receiving huge earnings.
Forecast and Belief
The 28-year-old predicted a KO victory in round four or five and claimed he would stop the long-awaited Fury-Joshua bout, which is apparently being planned for two years from now.
"It's going to be myself against Tyson Fury in the coming year," Paul declared.
Size Difference
As both boxers engaged in the traditional face-off, with their height and weight contrast evident, it drove home just how surprising this entire matchup is - and how astonishing it is that the match is truly proceeding.
