The British boxer is set to fight Jake Paul in an eight-bout match which will be broadcast in real-time on the streaming platform.
Briton Joshua said he will "overwhelm entirely" the American and "defeat" the American as the combatants met personally to promote the upcoming boxing match.
Former twice world title holder Anthony Joshua battles YouTuber-turned-boxer Jake Paul - in what is, on paper, a mammoth mismatch - at Miami's arena on 19 December.
Fighter's Attitude
"I will injure his face and break his body up. I aim to demonstrate my superiority," the British boxer, 35, said.
"I will dominate him completely. That's a fighter's mentality.
"I will really want to injure him. That's my intention."
Respectful Interaction
In spite of those words, a composed Anthony Joshua and internet personality Jake Paul - typically known for his theatrics - exchanged pleasantries and remained civil with each other.
Jake Paul rather targeted former Joshua's opponent Francis Ngannou and described him as "not serious" after Ngannou declined a fight offer.
Targeting Tyson Fury
Anthony Joshua, at the same time, took aim at British opponent Fury - and declined a £1m bet 'The Gypsy King' states he will put on a victory for Paul.
"[Paul] outshines Fury - he's present here," Joshua said.
"I acknowledge that."
Serious Fighter
In spite of declaring he will hurt Jake Paul, Anthony Joshua chose not to talk badly about his opponent's boxing ability.
"Jake Paul is a credible opponent," he said.
Paul's Background
Paul - who originally gained popularity on the Disney Channel - has mostly boxed MMA fighters or declining opponents since turning professional.
He was defeated by Briton Fury in last year.
Commercial Attraction
However, the novice is still one of the sport's biggest money-making draws, frequently receiving massive financial rewards.
Forecast and Confidence
The 28-year-old forecast a KO victory in rounds four or five and asserted he would stop the highly-expected match between Joshua and Fury, which is allegedly under discussion for 2026.
"The next fight will be myself against Tyson Fury in the coming year," Paul declared.
Size Disparity
As both boxers engaged in the usual confrontation, with their height and weight contrast on show, it drove home just how improbable this whole event is - and how amazing it is that the fight is really going ahead.
