Anthony Joshua will face Jake Paul in an eight-bout contest which will be broadcast live on the streaming platform.
Briton Joshua declared he will "overwhelm entirely" the American and "overpower" the American as the pair confronted each other to publicize the upcoming boxing match.
Former two time unified heavyweight champion Joshua meets YouTuber-turned-boxer Jake Paul - in what is, theoretically, a mammoth uneven pairing - at Miami arena on 19 December.
"I'm going to injure his face and break his body up. My goal is to show I'm the better fighter," the British boxer, 35 years old, declared.
"I plan to overwhelm him. That's the boxer's mindset.
"I intend to really want to injure him. That's my goal."
Despite those words, a calm Anthony Joshua and social media star Paul - normally famous for his theatrics - were respectful and maintained decorum with each other.
Paul instead targeted former Joshua's rival Francis Ngannou and described him as "not serious" after Ngannou declined a match opportunity.
Joshua, in the meantime, took aim at British opponent Fury - and rejected a £1m bet 'The Gypsy King' says he will place on a Paul victory.
"Jake Paul is better than Fury - he's actually sitting here," Joshua commented.
"I respect him for that."
Despite saying he intends to damage his opponent, Anthony Joshua refused to talk badly about his rival's fighting skills.
"Jake is a legitimate boxer," he remarked.
Paul - who first rose to fame on the Disney Channel - has mainly fought MMA fighters or past-their-prime fighters since becoming pro.
He was defeated by British fighter Fury in last year.
Still, the novice remains one of boxing's largest money-making draws, frequently receiving substantial paydays.
The 28 year old predicted a KO victory in rounds four or five and asserted he would derail the long-awaited Fury-Joshua bout, which is reportedly under discussion for 2026.
"It will be my match with Fury in the coming year," Paul said.
As both boxers met for the traditional stare-down, with their size difference clearly visible, it emphasized just how unlikely this whole event is - and how amazing it is that the fight is actually proceeding.
