The British boxer will face the American YouTuber in an eight round contest which will be shown in real-time on the streaming platform.
Briton Anthony Joshua said he will "overwhelm entirely" the American and "break" the American as the two fighters confronted each other to promote next month's bout.
Former twice unified boxing king Anthony Joshua battles social media star turned fighter Paul - in what is, theoretically, a huge disparity - at Miami's arena on December 19th.
Fighter's Attitude
"I'm going to break his face and damage his physique. I'm here to prove I'm the better fighter," Joshua, 35 years old, declared.
"I plan to overwhelm him. That's how fighters think.
"I'm going to genuinely try to injure him. That's my intention."
Respectful Exchange
Despite such comments, a calm Joshua and social media star Paul - usually known for his theatrics - shared friendly words and remained civil with each other.
Paul rather targeted ex Joshua opponent the Cameroonian fighter and described him as "a joke" after Ngannou rejected a match opportunity.
Taking Aim at Fury
Anthony Joshua, meanwhile, took aim at British rival Fury - and rejected a million-pound wager 'The Gypsy King' states he will put on a Paul win.
"[Paul] is superior to Tyson Fury - he showed up," the boxer commented.
"I acknowledge that."
Legitimate Fighter
In spite of stating he plans to punish Paul, Joshua refused to comment unfavorably about his opponent's pugilistic talent.
"Jake Paul is a serious fighter," he said.
Jake Paul's History
Paul - who originally gained popularity on the Disney Channel - has mainly fought mixed martial artists or past-their-prime fighters since turning professional.
He lost to Briton Fury in last year.
Commercial Attraction
Nevertheless, the inexperienced fighter continues to be one of boxing's biggest financial successes, regularly earning huge earnings.
Forecast and Belief
The 28-year-old predicted a KO victory in the fourth or fifth round and stated he would prevent the long-awaited match between Joshua and Fury, which is reportedly under discussion for two years from now.
"It will be my match with Fury in the coming year," Paul said.
Physical Disparity
As both boxers met for the traditional face-off, with their size difference evident, it drove home just how surprising this entire matchup is - and how astonishing it is that the bout is actually proceeding.
