The British boxer prepares to battle the American YouTuber in an eight round fight which will be streamed in real-time on the streaming platform.
Briton Joshua said he will "stamp all over" the American and "break" his opponent as the pair confronted each other to promote next month's bout.
Ex twice unified heavyweight champion Joshua meets social media star turned fighter Jake Paul - in what is, on paper, a mammoth uneven pairing - at Miami venue on 19 December.
"I'm going to injure his face and break his body up. I'm here to prove I'm superior," Joshua, 35, stated.
"I plan to overwhelm him. That's the boxer's mindset.
"I intend to seriously aim to hurt him. That's my goal."
In spite of such comments, a composed Anthony Joshua and social media star Paul - typically famous for his showmanship - shared friendly words and kept it respectful with each other.
Jake Paul instead criticized ex Joshua's opponent Francis Ngannou and described him as "not serious" after Ngannou declined a match opportunity.
Joshua, meanwhile, took aim at British opponent Fury - and declined a £1m bet 'Tyson Fury' says he will place on a Paul win.
"[Paul] is better than Tyson Fury - he's actually sitting here," the boxer said.
"I give him credit for that."
In spite of declaring he will hurt Jake Paul, Anthony Joshua refused to speak negatively about his opponent's pugilistic talent.
"Jake Paul is a credible opponent," he said.
Jake Paul - who first rose to fame on the television network - has mainly boxed mixed martial artists or past-their-prime fighters since entering professional boxing.
He was defeated by British fighter Tommy Fury in 2023.
However, the novice continues to be one of the sport's biggest money-making draws, regularly earning huge paydays.
The 28-year-old anticipated a knockout win in rounds four or five and claimed he would prevent the much-anticipated match between Joshua and Fury, which is reportedly under discussion for two years from now.
"The next fight will be me versus Tyson Fury in the coming year," Jake Paul said.
As both boxers met for the traditional stare-down, with their physical disparity clearly visible, it drove home just how surprising this entire matchup is - and how astonishing it is that the bout is truly happening.
