The British boxer will face the American YouTuber in an eight round match which will be shown live on Netflix.
Briton Anthony Joshua stated he will "overwhelm entirely" the American and "defeat" his opponent as the pair confronted each other to promote next month's bout.
Ex two time unified heavyweight champion Joshua faces YouTuber-turned-boxer Jake Paul - in what is, on paper, a huge disparity - at Miami's arena on 19 December.
"I will break his face and damage his physique. I aim to demonstrate I'm the better fighter," the British boxer, 35, declared.
"I plan to overwhelm him. That's how fighters think.
"I'm going to genuinely try to hurt him. That's what I want to do."
In spite of these statements, a relaxed Joshua and internet personality Paul - normally recognized for his dramatics - were respectful and kept it respectful with each other.
Paul rather criticized ex Joshua's rival the Cameroonian fighter and labeled him "ridiculous" after Ngannou turned down a fight offer.
Anthony Joshua, at the same time, took aim at British opponent Fury - and declined a £1m bet 'Tyson Fury' claims he will make on a victory for Paul.
"[Paul] is superior to Fury - he showed up," Joshua commented.
"I respect him for that."
In spite of saying he intends to punish Paul, Anthony Joshua declined to talk badly about his rival's boxing ability.
"Jake Paul is a credible opponent," he remarked.
Paul - who originally gained popularity on the television network - has mostly fought MMA fighters or past-their-prime fighters since entering professional boxing.
He lost to Briton Tommy Fury in 2023.
Nevertheless, the inexperienced fighter remains one of boxing's biggest financial successes, consistently making massive earnings.
The 28-year-old forecast a stoppage in round four or five and claimed he would stop the much-anticipated Fury-Joshua bout, which is allegedly in the works for 2026.
"The next fight will be myself against Tyson Fury in the coming year," Paul said.
As both boxers participated in the traditional stare-down, with their height and weight contrast clearly visible, it emphasized just how surprising this complete situation is - and how remarkable it is that the fight is actually happening.
