Anthony Joshua is set to fight Jake Paul in an eight round match which will be streamed in real-time on the streaming platform.
Briton Joshua declared he will "stamp all over" the American and "break" his opponent as the combatants met personally to build hype for the upcoming heavyweight fight.
Former twice world boxing king Joshua faces YouTuber-turned-boxer Paul - in what is, theoretically, a mammoth disparity - at Miami venue on December 19th.
Fighter's Mentality
"I will break his face and damage his physique. I'm here to prove I'm superior," the British boxer, 35, said.
"I will dominate him completely. That's a fighter's mentality.
"I'm going to genuinely try to hurt him. That's what I want to do."
Respectful Exchange
In spite of such comments, a relaxed Anthony Joshua and social media star Jake Paul - normally recognized for his theatrics - exchanged pleasantries and kept it respectful with each other.
Jake Paul instead criticized former Joshua opponent the Cameroonian fighter and labeled him "a joke" after Ngannou rejected a bout proposal.
Taking Aim at Tyson Fury
Joshua, at the same time, took aim at British rival Fury - and refused a large bet 'The Gypsy King' says he will place on a Paul win.
"Jake Paul is superior to Tyson Fury - he's actually sitting here," Joshua commented.
"I give him credit for that."
Legitimate Opponent
Despite saying he intends to hurt Jake Paul, Joshua refused to comment unfavorably about his opponent's fighting skills.
"Jake Paul is a legitimate boxer," he stated.
Jake Paul's Background
Jake Paul - who initially became famous on the television network - has primarily fought mixed martial artists or past-their-prime fighters since turning professional.
He was defeated by British fighter Tommy Fury in last year.
Commercial Success
Still, the novice is still one of boxing's biggest money-making draws, frequently receiving substantial earnings.
Forecast and Belief
The 28-year-old forecast a knockout win in the fourth or fifth round and asserted he would prevent the highly-expected match between Joshua and Fury, which is reportedly being planned for two years from now.
"It will be my match with Fury next year," Paul said.
Size Disparity
As Joshua and Paul met for the traditional confrontation, with their size difference evident, it highlighted just how surprising this whole event is - and how astonishing it is that the fight is actually going ahead.
