Anthony Joshua prepares to battle Jake Paul in an eight-bout contest which will be broadcast in real-time on the streaming platform.
Briton Joshua stated he will "dominate completely" the American and "overpower" the American as the combatants came face-to-face to build hype for next month's heavyweight fight.
Former twice world heavyweight champion Anthony Joshua faces social media star turned fighter Jake Paul - in what is, by the numbers, a massive mismatch - at Miami venue on 19 December.
Fighter's Mindset
"I will injure his face and hurt his body. I aim to demonstrate my superiority," the British boxer, 35 years old, said.
"I plan to overwhelm him. That's the boxer's mindset.
"I intend to seriously aim to injure him. That's my intention."
Civil Interaction
Despite such comments, a composed Anthony Joshua and internet personality Paul - typically known for his showmanship - shared friendly words and maintained decorum with each other.
Jake Paul instead targeted former Joshua opponent the Cameroonian fighter and called him "not serious" after the Cameroonian rejected a bout proposal.
Targeting Fury
Anthony Joshua, meanwhile, took aim at British opponent Fury - and rejected a large bet 'Tyson Fury' states he will put on a Paul victory.
"[Paul] outshines Fury - he's actually sitting here," the boxer said.
"I acknowledge that."
Serious Fighter
In spite of stating he plans to hurt Jake Paul, Joshua chose not to speak negatively about his rival's pugilistic talent.
"Jake Paul is a legitimate boxer," he remarked.
Paul's Background
Jake Paul - who originally gained popularity on the television network - has mostly fought mixed martial artists or past-their-prime fighters since turning professional.
He lost to British fighter Fury in last year.
Commercial Attraction
Nevertheless, the inexperienced fighter is still one of the sport's greatest financial successes, frequently receiving massive earnings.
Forecast and Confidence
The 28 year old anticipated a knockout win in the fourth or fifth round and stated he would derail the long-awaited Fury-Joshua bout, which is apparently in the works for two years from now.
"It's going to be me versus Tyson Fury next year," Jake Paul declared.
Physical Disparity
As both boxers met for the customary stare-down, with their height and weight contrast on show, it highlighted just how unlikely this whole event is - and how amazing it is that the bout is really proceeding.
