The British boxer will face Jake Paul in an eight-round match which will be broadcast in real-time on Netflix.
Briton Joshua stated he will "dominate completely" Jake Paul and "break" his opponent as the pair came face-to-face to publicize next month's bout.
Ex twice world boxing king Anthony Joshua battles social media star turned fighter Jake Paul - in what is, on paper, a huge mismatch - at Miami arena on 19 December.
Fighter's Mindset
"I will break his face and damage his physique. My goal is to show my superiority," Joshua, 35, said.
"I'll stamp all over him. That's the boxer's mindset.
"I'm going to seriously aim to injure him. That's what I want to do."
Civil Interaction
In spite of such comments, a calm Joshua and social media star Jake Paul - typically known for his showmanship - were respectful and remained civil with each other.
Jake Paul instead attacked ex Joshua rival Francis Ngannou and labeled him "not serious" after the Cameroonian rejected a fight offer.
Targeting Fury
Anthony Joshua, at the same time, criticized British rival Fury - and refused a large bet 'Tyson Fury' states he will put on a Paul victory.
"[Paul] outshines Tyson Fury - he showed up," the boxer stated.
"I acknowledge that."
Legitimate Opponent
Despite declaring he will damage his opponent, Joshua refused to speak negatively about his opponent's pugilistic talent.
"Jake Paul is a credible opponent," he said.
Paul's History
Jake Paul - who originally gained popularity on the television network - has mainly boxed mixed martial artists or faded names since turning professional.
He was defeated by Briton Tommy Fury in last year.
Financial Attraction
Nevertheless, the novice continues to be one of boxing's biggest commercial attractions, regularly earning huge earnings.
Forecast and Confidence
The 28-year-old forecast a knockout win in the fourth or fifth round and claimed he would derail the highly-expected Joshua–Fury fight, which is apparently in the works for two years from now.
"It's going to be myself against Tyson Fury next year," Paul declared.
Physical Difference
As both boxers participated in the usual stare-down, with their height and weight contrast on show, it drove home just how surprising this whole event is - and how astonishing it is that the match is really proceeding.
