The British boxer will face Jake Paul in an eight-bout fight which will be shown in real-time on the streaming platform.
Briton Joshua declared he will "overwhelm entirely" the American and "break" the American as the combatants confronted each other to build hype for the upcoming bout.
Former twice world heavyweight champion Joshua faces social media star turned fighter Paul - in what is, on paper, a mammoth disparity - at Miami's Kaseya Center on 19 December.
Fighter's Mentality
"I'm going to damage his features and damage his physique. My goal is to show I'm superior," the British boxer, 35 years old, stated.
"I plan to overwhelm him. That's the boxer's mindset.
"I'm going to genuinely try to injure him. That's my goal."
Respectful Interaction
In spite of those words, a calm Joshua and internet personality Paul - typically recognized for his theatrics - shared friendly words and remained civil with each other.
Paul instead criticized former Joshua's opponent the Cameroonian fighter and called him "a joke" after Ngannou rejected a bout proposal.
Targeting Fury
Anthony Joshua, at the same time, criticized UK opponent Tyson Fury - and rejected a £1m bet 'The Gypsy King' states he will put on a Paul victory.
"[Paul] outshines Fury - he's present here," Joshua said.
"I give him credit for that."
Serious Opponent
Despite stating he plans to hurt Jake Paul, Joshua refused to speak negatively about his rival's fighting skills.
"Jake is a legitimate boxer," he remarked.
Jake Paul's Background
Jake Paul - who first rose to fame on the television network - has mainly boxed mixed martial artists or past-their-prime fighters since turning professional.
He was defeated by Briton Tommy Fury in last year.
Commercial Success
Still, the inexperienced fighter is still one of the sport's largest commercial attractions, consistently making huge financial rewards.
Forecast and Belief
The 28 year old forecast a KO victory in rounds four or five and asserted he would stop the highly-expected Joshua–Fury fight, which is reportedly under discussion for 2026.
"It's going to be myself against Tyson Fury in the coming year," Jake Paul stated.
Size Disparity
As Joshua and Paul met for the customary stare-down, with their physical disparity on show, it emphasized just how surprising this whole event is - and how remarkable it is that the fight is actually proceeding.
