Anthony Joshua is set to fight Jake Paul in an eight-bout contest which will be streamed live on the streaming platform.
British boxer Joshua declared he will "stamp all over" the American and "overpower" his opponent as the combatants met personally to build hype for the upcoming heavyweight fight.
Ex two time unified boxing king Anthony Joshua faces YouTuber-turned-boxer Paul - in what is, by the numbers, a huge disparity - at Miami's venue on 19 December.
Boxer's Mentality
"I will injure his face and damage his physique. I aim to demonstrate I'm superior," Joshua, 35 years old, declared.
"I'll stamp all over him. That's the boxer's mindset.
"I will genuinely try to cause him pain. That's my intention."
Respectful Interaction
Despite those words, a composed Joshua and social media star Paul - usually known for his showmanship - shared friendly words and kept it respectful with each other.
Paul instead targeted ex Joshua rival the Cameroonian fighter and called him "a joke" after Ngannou rejected a bout proposal.
Taking Aim at Tyson Fury
Joshua, in the meantime, took aim at UK rival Fury - and refused a £1m bet 'The Gypsy King' says he will place on a Paul win.
"Jake Paul is superior to Tyson Fury - he's present here," the boxer stated.
"I give him credit for that."
Legitimate Opponent
In spite of declaring he will punish Paul, Joshua refused to speak negatively about his rival's fighting skills.
"Jake Paul is a legitimate boxer," he said.
Paul's History
Jake Paul - who originally gained popularity on the television network - has mainly boxed mixed martial artists or past-their-prime fighters since becoming pro.
He was defeated by Briton Fury in last year.
Financial Success
Still, the inexperienced fighter remains one of the sport's largest money-making draws, frequently receiving huge financial rewards.
Forecast and Confidence
The 28 year old anticipated a knockout win in round four or five and claimed he would prevent the long-awaited Fury-Joshua bout, which is apparently in the works for two years from now.
"It's going to be me versus Tyson Fury in the coming year," Jake Paul declared.
Size Difference
As both boxers met for the usual face-off, with their physical disparity evident, it highlighted just how unlikely this whole event is - and how amazing it is that the bout is really going ahead.
