Anthony Joshua will face the American YouTuber in an eight-bout contest which will be shown in real-time on the streaming platform.
Briton Joshua declared he will "stamp all over" the American and "overpower" the American as the pair met personally to build hype for next month's heavyweight fight.
Former twice world title holder Joshua meets YouTuber-turned-boxer Jake Paul - in what is, on paper, a huge disparity - at Miami's arena on 19 December.
Fighter's Attitude
"I will injure his face and hurt his body. I aim to demonstrate my superiority," the British boxer, 35, declared.
"I'll stamp all over him. That's how fighters think.
"I'm going to seriously aim to cause him pain. That's what I want to do."
Respectful Interaction
Despite those words, a composed Joshua and social media star Jake Paul - typically recognized for his showmanship - shared friendly words and maintained decorum with each other.
Jake Paul instead criticized former Joshua's opponent Francis Ngannou and called him "a joke" after Ngannou rejected a bout proposal.
Targeting Fury
Anthony Joshua, at the same time, criticized UK opponent Tyson Fury - and rejected a large bet 'Tyson Fury' states he will put on a Paul win.
"[Paul] is superior to Tyson Fury - he's actually sitting here," the boxer stated.
"I give him credit for that."
Legitimate Fighter
Despite declaring he will damage his opponent, Joshua declined to speak negatively about his opponent's pugilistic talent.
"Jake is a serious fighter," he remarked.
Jake Paul's Background
Jake Paul - who first rose to fame on the Disney Channel - has primarily boxed mixed martial artists or past-their-prime fighters since entering professional boxing.
He was defeated by Briton Fury in last year.
Commercial Success
Nevertheless, the novice is still one of the sport's greatest money-making draws, consistently making massive paydays.
Prediction and Belief
The 28-year-old anticipated a stoppage in rounds four or five and stated he would stop the long-awaited Joshua–Fury fight, which is reportedly being planned for two years from now.
"The next fight will be me versus Tyson Fury in the coming year," Paul declared.
Physical Difference
As Joshua and Paul participated in the customary confrontation, with their physical disparity evident, it highlighted just how unlikely this entire matchup is - and how astonishing it is that the fight is actually going ahead.
