The British boxer is set to fight the American YouTuber in an eight-bout contest which will be broadcast in real-time on the streaming platform.
Briton Joshua declared he will "dominate completely" Jake Paul and "break" the American as the two fighters confronted each other to promote the upcoming bout.
Former two time world boxing king Anthony Joshua meets YouTuber-turned-boxer Paul - in what is, by the numbers, a massive mismatch - at Miami venue on 19 December.
Boxer's Mindset
"I'm going to injure his face and break his body up. My goal is to show my superiority," Joshua, 35, said.
"I will dominate him completely. That's how fighters think.
"I will really want to cause him pain. That's what I want to do."
Respectful Interaction
Despite those words, a composed Anthony Joshua and social media star Paul - normally famous for his dramatics - were respectful and kept it respectful with each other.
Paul rather targeted former Joshua opponent the Cameroonian fighter and described him as "ridiculous" after Ngannou rejected a bout proposal.
Targeting Fury
Anthony Joshua, meanwhile, targeted UK opponent Tyson Fury - and rejected a million-pound wager 'Tyson Fury' states he will put on a victory for Paul.
"Jake Paul is superior to Tyson Fury - he's present here," Joshua said.
"I acknowledge that."
Serious Fighter
Despite stating he plans to damage his opponent, Joshua refused to talk badly about his rival's pugilistic talent.
"Jake Paul is a credible opponent," he stated.
Jake Paul's History
Paul - who initially became famous on the television network - has mostly fought MMA fighters or past-their-prime fighters since becoming pro.
He lost to British fighter Fury in last year.
Financial Attraction
However, the novice is still one of boxing's biggest commercial attractions, consistently making massive financial rewards.
Prediction and Belief
The 28-year-old forecast a KO victory in rounds four or five and asserted he would derail the much-anticipated Fury-Joshua bout, which is reportedly under discussion for two years from now.
"It's going to be me versus Tyson Fury next year," Paul said.
Size Difference
As the two fighters participated in the usual face-off, with their size difference evident, it drove home just how improbable this complete situation is - and how remarkable it is that the match is actually going ahead.
