The British boxer will face Jake Paul in an eight round match which will be shown in real-time on Netflix.
Briton Joshua declared he will "overwhelm entirely" the American and "overpower" the American as the pair confronted each other to promote next month's heavyweight fight.
Former twice world boxing king Joshua battles YouTuber-turned-boxer Paul - in what is, theoretically, a mammoth mismatch - at Miami venue on 19 December.
Boxer's Mentality
"I will break his face and break his body up. My goal is to show I'm superior," the British boxer, 35, stated.
"I plan to overwhelm him. That's how fighters think.
"I will genuinely try to injure him. That's my goal."
Respectful Interaction
Despite these statements, a relaxed Anthony Joshua and social media star Paul - typically known for his dramatics - exchanged pleasantries and kept it respectful with each other.
Paul rather targeted former Joshua rival Francis Ngannou and called him "ridiculous" after Ngannou rejected a bout proposal.
Targeting Tyson Fury
Joshua, at the same time, took aim at UK rival Tyson Fury - and rejected a million-pound wager 'Tyson Fury' says he will place on a Paul victory.
"Jake Paul is superior to Tyson Fury - he's actually sitting here," Joshua commented.
"I respect him for that."
Legitimate Opponent
Despite stating he plans to hurt Jake Paul, Anthony Joshua refused to speak negatively about his rival's fighting skills.
"Jake is a serious fighter," he remarked.
Jake Paul's Background
Paul - who originally gained popularity on the television network - has mainly boxed mixed martial artists or past-their-prime fighters since becoming pro.
He lost to British fighter Fury in 2023.
Financial Success
However, the inexperienced fighter remains one of boxing's largest financial successes, frequently receiving huge financial rewards.
Forecast and Confidence
The 28 year old anticipated a stoppage in round four or five and stated he would derail the much-anticipated Fury-Joshua bout, which is apparently in the works for 2026.
"It will be me versus Tyson Fury next year," Paul declared.
Size Difference
As the two fighters engaged in the usual confrontation, with their size difference clearly visible, it highlighted just how surprising this entire matchup is - and how amazing it is that the fight is really happening.
