The British boxer will face the American YouTuber in an eight-bout contest which will be streamed in real-time on the streaming platform.
Briton Anthony Joshua declared he will "stamp all over" the American and "break" the American as the combatants met personally to build hype for the upcoming heavyweight fight.
Former two time world heavyweight champion Joshua battles social media star turned fighter Paul - in what is, theoretically, a huge disparity - at Miami Kaseya Center on 19 December.
Boxer's Attitude
"I plan to injure his face and break his body up. My goal is to show my superiority," Joshua, 35, said.
"I'll stamp all over him. That's the boxer's mindset.
"I'm going to seriously aim to cause him pain. That's my intention."
Civil Exchange
Despite such comments, a calm Anthony Joshua and internet personality Paul - typically recognized for his theatrics - exchanged pleasantries and maintained decorum with each other.
Jake Paul rather targeted former Joshua opponent the Cameroonian fighter and labeled him "ridiculous" after Ngannou declined a match opportunity.
Taking Aim at Fury
Anthony Joshua, meanwhile, took aim at British opponent Tyson Fury - and refused a large bet 'Tyson Fury' says he will place on a Paul victory.
"Jake Paul is superior to Fury - he's actually sitting here," Joshua said.
"I give him credit for that."
Serious Fighter
In spite of saying he intends to punish Paul, Anthony Joshua refused to speak negatively about his rival's boxing ability.
"Jake Paul is a serious fighter," he remarked.
Paul's History
Paul - who originally gained popularity on the Disney Channel - has mainly fought MMA fighters or declining opponents since entering professional boxing.
He was defeated by Briton Tommy Fury in last year.
Financial Attraction
Still, the inexperienced fighter continues to be one of the sport's biggest financial successes, consistently making massive financial rewards.
Prediction and Confidence
The 28-year-old forecast a knockout win in the fourth or fifth round and asserted he would derail the long-awaited Joshua–Fury fight, which is allegedly in the works for two years from now.
"The next fight will be me versus Tyson Fury next year," Jake Paul stated.
Physical Disparity
As both boxers engaged in the customary face-off, with their size difference on show, it drove home just how improbable this whole event is - and how astonishing it is that the fight is actually going ahead.
