The British boxer will face Jake Paul in an eight round fight which will be broadcast in real-time on Netflix.
Briton Joshua stated he will "dominate completely" the American and "overpower" the American as the two fighters confronted each other to build hype for next month's bout.
Former two-time unified heavyweight champion Anthony Joshua faces social media star turned fighter Paul - in what is, on paper, a mammoth disparity - at Miami venue on 19 December.
Boxer's Mindset
"I'm going to break his face and hurt his body. I'm here to prove my superiority," Joshua, 35 years old, declared.
"I will dominate him completely. That's a fighter's mentality.
"I will really want to hurt him. That's what I want to do."
Respectful Exchange
In spite of such comments, a calm Joshua and social media star Paul - usually famous for his dramatics - were respectful and maintained decorum with each other.
Paul rather attacked ex Joshua opponent the Cameroonian fighter and described him as "ridiculous" after Ngannou turned down a match opportunity.
Targeting Tyson Fury
Joshua, at the same time, targeted UK rival Fury - and refused a large bet 'The Gypsy King' claims he will make on a Paul win.
"Jake Paul outshines Fury - he's present here," the boxer commented.
"I respect him for that."
Legitimate Fighter
In spite of declaring he will damage his opponent, Anthony Joshua declined to speak negatively about his opponent's pugilistic talent.
"Jake is a credible opponent," he said.
Paul's History
Jake Paul - who first rose to fame on the television network - has primarily boxed MMA fighters or faded names since turning professional.
He was defeated by Briton Tommy Fury in 2023.
Commercial Success
Nevertheless, the inexperienced fighter is still one of the sport's greatest financial successes, consistently making massive financial rewards.
Prediction and Confidence
The 28-year-old forecast a stoppage in rounds four or five and stated he would derail the much-anticipated Fury-Joshua bout, which is apparently in the works for two years from now.
"It will be my match with Fury in the coming year," Jake Paul stated.
Size Disparity
As both boxers met for the traditional stare-down, with their size difference evident, it highlighted just how unlikely this complete situation is - and how remarkable it is that the fight is actually happening.
