The British boxer prepares to battle Jake Paul in an eight-bout match which will be shown live on the streaming platform.
Briton Joshua declared he will "overwhelm entirely" Jake Paul and "break" his opponent as the pair confronted each other to build hype for the upcoming heavyweight fight.
Ex two time unified heavyweight champion Anthony Joshua faces YouTuber-turned-boxer Paul - in what is, by the numbers, a huge uneven pairing - at Miami's Kaseya Center on 19 December.
Fighter's Mindset
"I'm going to damage his features and hurt his body. I'm here to prove I'm the better fighter," Joshua, 35 years old, stated.
"I plan to overwhelm him. That's the boxer's mindset.
"I'm going to genuinely try to hurt him. That's what I want to do."
Civil Exchange
Despite such comments, a relaxed Anthony Joshua and social media star Jake Paul - normally recognized for his dramatics - were respectful and maintained decorum with each other.
Paul rather criticized former Joshua's opponent the Cameroonian fighter and called him "ridiculous" after Ngannou declined a match opportunity.
Taking Aim at Fury
Joshua, meanwhile, took aim at British rival Fury - and declined a £1m bet 'Tyson Fury' states he will put on a Paul win.
"Jake Paul outshines Tyson Fury - he's present here," Joshua said.
"I give him credit for that."
Serious Opponent
Despite saying he intends to punish Paul, Anthony Joshua refused to talk badly about his rival's pugilistic talent.
"Jake is a legitimate boxer," he stated.
Paul's History
Jake Paul - who originally gained popularity on the television network - has mainly boxed mixed martial artists or declining opponents since entering professional boxing.
He lost to British fighter Fury in last year.
Commercial Success
Still, the novice continues to be one of boxing's greatest financial successes, frequently receiving substantial paydays.
Prediction and Confidence
The 28 year old predicted a KO victory in rounds four or five and asserted he would derail the highly-expected match between Joshua and Fury, which is allegedly under discussion for two years from now.
"It will be me versus Tyson Fury in the coming year," Jake Paul stated.
Size Difference
As both boxers participated in the traditional face-off, with their physical disparity evident, it highlighted just how unlikely this whole event is - and how remarkable it is that the match is really happening.
