The British boxer will face the American YouTuber in an eight round contest which will be streamed in real-time on the streaming platform.
British boxer Joshua said he will "stamp all over" Jake Paul and "overpower" the American as the two fighters came face-to-face to build hype for the upcoming boxing match.
Former two time unified title holder Joshua faces social media star turned fighter Paul - in what is, on paper, a mammoth disparity - at Miami venue on 19 December.
Fighter's Mentality
"I plan to break his face and break his body up. I'm here to prove my superiority," the British boxer, 35 years old, declared.
"I will dominate him completely. That's a fighter's mentality.
"I intend to genuinely try to hurt him. That's what I want to do."
Respectful Interaction
Despite these statements, a relaxed Joshua and social media star Jake Paul - usually known for his theatrics - were respectful and remained civil with each other.
Jake Paul instead targeted former Joshua's rival Francis Ngannou and described him as "not serious" after Ngannou declined a match opportunity.
Taking Aim at Tyson Fury
Joshua, in the meantime, criticized UK rival Tyson Fury - and rejected a £1m bet 'Tyson Fury' states he will put on a victory for Paul.
"[Paul] outshines Tyson Fury - he showed up," the boxer stated.
"I give him credit for that."
Serious Opponent
In spite of declaring he will damage his opponent, Anthony Joshua refused to talk badly about his rival's fighting skills.
"Jake Paul is a serious fighter," he stated.
Jake Paul's Background
Jake Paul - who originally gained popularity on the television network - has primarily fought MMA fighters or past-their-prime fighters since becoming pro.
He was defeated by Briton Fury in last year.
Financial Success
However, the inexperienced fighter remains one of the sport's largest financial successes, frequently receiving huge paydays.
Prediction and Belief
The 28 year old anticipated a knockout win in round four or five and claimed he would prevent the highly-expected match between Joshua and Fury, which is allegedly under discussion for two years from now.
"The next fight will be myself against Tyson Fury next year," Paul said.
Size Disparity
As both boxers engaged in the traditional face-off, with their height and weight contrast clearly visible, it highlighted just how surprising this whole event is - and how astonishing it is that the match is actually going ahead.
