Anthony Joshua will face the American YouTuber in an eight-round fight which will be broadcast live on the streaming platform.
Briton Anthony Joshua declared he will "overwhelm entirely" the American and "overpower" his opponent as the two fighters confronted each other to publicize the upcoming bout.
Ex twice world heavyweight champion Joshua faces social media star turned fighter Paul - in what is, by the numbers, a massive disparity - at Miami arena on 19 December.
Fighter's Mentality
"I plan to break his face and break his body up. I aim to demonstrate I'm the better fighter," Joshua, 35, said.
"I plan to overwhelm him. That's a fighter's mentality.
"I will seriously aim to cause him pain. That's my intention."
Civil Interaction
Despite those words, a composed Anthony Joshua and social media star Paul - normally recognized for his theatrics - were respectful and kept it respectful with each other.
Paul rather targeted ex Joshua's opponent Francis Ngannou and called him "not serious" after the Cameroonian declined a match opportunity.
Targeting Tyson Fury
Anthony Joshua, at the same time, took aim at UK opponent Tyson Fury - and declined a large bet 'The Gypsy King' states he will put on a Paul victory.
"Jake Paul outshines Fury - he's present here," the boxer commented.
"I respect him for that."
Legitimate Fighter
Despite declaring he will hurt Jake Paul, Anthony Joshua chose not to talk badly about his opponent's pugilistic talent.
"Jake is a serious fighter," he said.
Jake Paul's History
Paul - who originally gained popularity on the television network - has primarily fought mixed martial artists or faded names since turning professional.
He was defeated by Briton Fury in last year.
Commercial Success
However, the relative newcomer remains one of the sport's biggest financial successes, regularly earning massive paydays.
Prediction and Confidence
The 28-year-old predicted a knockout win in the fourth or fifth round and claimed he would prevent the highly-expected match between Joshua and Fury, which is apparently in the works for two years from now.
"The next fight will be me versus Tyson Fury in the coming year," Jake Paul declared.
Physical Disparity
As both boxers participated in the usual stare-down, with their size difference clearly visible, it drove home just how improbable this complete situation is - and how astonishing it is that the bout is really going ahead.
