The British boxer will face the American YouTuber in an eight-bout contest which will be shown live on the streaming platform.
Briton Joshua said he will "overwhelm entirely" the American and "defeat" the American as the pair confronted each other to publicize next month's boxing match.
Ex twice world heavyweight champion Joshua battles social media star turned fighter Paul - in what is, on paper, a huge uneven pairing - at Miami's Kaseya Center on 19 December.
Fighter's Mindset
"I'm going to break his face and damage his physique. I'm here to prove I'm superior," Joshua, 35 years old, stated.
"I'll stamp all over him. That's the boxer's mindset.
"I'm going to seriously aim to hurt him. That's my goal."
Civil Interaction
Despite these statements, a composed Anthony Joshua and social media star Paul - normally known for his dramatics - exchanged pleasantries and maintained decorum with each other.
Paul instead targeted former Joshua opponent the Cameroonian fighter and described him as "a joke" after Ngannou turned down a fight offer.
Targeting Tyson Fury
Anthony Joshua, meanwhile, criticized British opponent Fury - and refused a large bet 'Tyson Fury' states he will put on a Paul victory.
"[Paul] is superior to Fury - he's actually sitting here," the boxer said.
"I respect him for that."
Serious Opponent
In spite of stating he plans to punish Paul, Anthony Joshua chose not to comment unfavorably about his rival's boxing ability.
"Jake Paul is a serious fighter," he stated.
Paul's Background
Paul - who first rose to fame on the television network - has mainly fought mixed martial artists or past-their-prime fighters since entering professional boxing.
He lost to British fighter Tommy Fury in 2023.
Financial Attraction
Still, the inexperienced fighter continues to be one of boxing's largest commercial attractions, consistently making massive earnings.
Prediction and Confidence
The 28-year-old anticipated a KO victory in round four or five and asserted he would derail the long-awaited Fury-Joshua bout, which is allegedly in the works for 2026.
"The next fight will be me versus Tyson Fury next year," Paul said.
Size Disparity
As Joshua and Paul met for the usual face-off, with their size difference evident, it drove home just how unlikely this entire matchup is - and how astonishing it is that the bout is really proceeding.
