The British boxer will face the American YouTuber in an eight-round contest which will be shown in real-time on Netflix.
British boxer Joshua declared he will "dominate completely" Jake Paul and "overpower" the American as the pair met personally to publicize the upcoming bout.
Former two-time unified title holder Anthony Joshua battles social media star turned fighter Paul - in what is, theoretically, a massive uneven pairing - at Miami Kaseya Center on 19 December.
"I'm going to break his face and break his body up. I aim to demonstrate I'm superior," the British boxer, 35, stated.
"I plan to overwhelm him. That's a fighter's mentality.
"I intend to seriously aim to injure him. That's what I want to do."
Despite such comments, a relaxed Joshua and social media star Jake Paul - normally recognized for his showmanship - exchanged pleasantries and kept it respectful with each other.
Jake Paul rather criticized ex Joshua rival Francis Ngannou and called him "ridiculous" after the Cameroonian declined a bout proposal.
Joshua, meanwhile, criticized British opponent Tyson Fury - and refused a million-pound wager 'The Gypsy King' says he will place on a Paul victory.
"Jake Paul is better than Tyson Fury - he's present here," Joshua said.
"I respect him for that."
Despite declaring he will hurt Jake Paul, Anthony Joshua declined to talk badly about his opponent's boxing ability.
"Jake Paul is a serious fighter," he remarked.
Jake Paul - who originally gained popularity on the television network - has mainly fought mixed martial artists or past-their-prime fighters since becoming pro.
He was defeated by British fighter Tommy Fury in 2023.
Nevertheless, the relative newcomer remains one of the sport's largest commercial attractions, frequently receiving huge financial rewards.
The 28 year old anticipated a stoppage in the fourth or fifth round and claimed he would derail the much-anticipated Fury-Joshua bout, which is allegedly under discussion for two years from now.
"The next fight will be me versus Tyson Fury in the coming year," Paul declared.
As Joshua and Paul participated in the traditional stare-down, with their size difference on show, it emphasized just how surprising this entire matchup is - and how astonishing it is that the match is really happening.
