The British boxer is set to fight the American YouTuber in an eight-bout fight which will be streamed live on the streaming platform.
Briton Joshua stated he will "overwhelm entirely" the American and "defeat" the American as the pair came face-to-face to publicize the upcoming boxing match.
Former twice unified heavyweight champion Joshua battles social media star turned fighter Paul - in what is, theoretically, a huge mismatch - at Miami's arena on December 19th.
Fighter's Mindset
"I will break his face and break his body up. I'm here to prove I'm superior," Joshua, 35, stated.
"I will dominate him completely. That's a fighter's mentality.
"I will genuinely try to injure him. That's my intention."
Respectful Interaction
In spite of those words, a composed Anthony Joshua and social media star Paul - typically famous for his showmanship - were respectful and kept it respectful with each other.
Paul rather targeted ex Joshua opponent Francis Ngannou and called him "ridiculous" after the Cameroonian declined a fight offer.
Taking Aim at Tyson Fury
Anthony Joshua, meanwhile, criticized UK rival Tyson Fury - and rejected a million-pound wager 'Tyson Fury' claims he will make on a victory for Paul.
"[Paul] is better than Fury - he's actually sitting here," Joshua commented.
"I give him credit for that."
Legitimate Fighter
Despite stating he plans to punish Paul, Joshua chose not to comment unfavorably about his opponent's boxing ability.
"Jake is a serious fighter," he said.
Jake Paul's History
Paul - who initially became famous on the television network - has mostly fought MMA fighters or declining opponents since turning professional.
He was defeated by Briton Fury in last year.
Financial Success
Nevertheless, the relative newcomer continues to be one of the sport's largest financial successes, consistently making massive earnings.
Prediction and Confidence
The 28 year old forecast a knockout win in the fourth or fifth round and stated he would derail the much-anticipated match between Joshua and Fury, which is reportedly under discussion for two years from now.
"It's going to be myself against Tyson Fury in the coming year," Jake Paul stated.
Physical Difference
As the two fighters participated in the customary face-off, with their height and weight contrast evident, it drove home just how unlikely this entire matchup is - and how amazing it is that the bout is really proceeding.
