The British boxer prepares to battle Jake Paul in an eight-bout fight which will be shown in real-time on the streaming platform.
British boxer Joshua said he will "overwhelm entirely" the American and "break" the American as the two fighters confronted each other to promote the upcoming bout.
Former twice unified title holder Joshua meets YouTuber-turned-boxer Paul - in what is, theoretically, a massive uneven pairing - at Miami venue on 19 December.
Boxer's Mindset
"I will damage his features and damage his physique. My goal is to show I'm superior," Joshua, 35, declared.
"I will dominate him completely. That's the boxer's mindset.
"I will really want to cause him pain. That's my goal."
Respectful Interaction
Despite those words, a relaxed Anthony Joshua and internet personality Paul - typically known for his showmanship - were respectful and remained civil with each other.
Jake Paul rather criticized ex Joshua's rival Francis Ngannou and described him as "not serious" after the Cameroonian turned down a bout proposal.
Taking Aim at Tyson Fury
Anthony Joshua, at the same time, targeted British opponent Tyson Fury - and rejected a £1m bet 'The Gypsy King' claims he will make on a victory for Paul.
"Jake Paul is better than Fury - he's actually sitting here," Joshua stated.
"I respect him for that."
Serious Fighter
In spite of stating he plans to punish Paul, Joshua refused to talk badly about his opponent's fighting skills.
"Jake is a legitimate boxer," he said.
Jake Paul's Background
Paul - who first rose to fame on the Disney Channel - has primarily fought mixed martial artists or past-their-prime fighters since turning professional.
He lost to Briton Tommy Fury in last year.
Financial Success
Still, the novice is still one of the sport's greatest commercial attractions, frequently receiving massive financial rewards.
Forecast and Belief
The 28 year old forecast a knockout win in rounds four or five and claimed he would stop the highly-expected match between Joshua and Fury, which is apparently under discussion for two years from now.
"The next fight will be me versus Tyson Fury in the coming year," Paul declared.
Size Disparity
As the two fighters engaged in the usual face-off, with their size difference on show, it drove home just how surprising this whole event is - and how remarkable it is that the fight is actually going ahead.
