The British boxer is set to fight the American YouTuber in an eight-bout contest which will be streamed in real-time on the streaming platform.
British boxer Joshua declared he will "overwhelm entirely" the American and "break" the American as the two fighters confronted each other to promote next month's heavyweight fight.
Ex two time unified title holder Anthony Joshua battles YouTuber-turned-boxer Paul - in what is, by the numbers, a mammoth disparity - at Miami arena on 19 December.
Boxer's Mindset
"I will injure his face and hurt his body. I'm here to prove my superiority," the British boxer, 35, said.
"I'll stamp all over him. That's how fighters think.
"I'm going to really want to hurt him. That's my intention."
Civil Interaction
Despite those words, a relaxed Anthony Joshua and internet personality Paul - usually recognized for his theatrics - were respectful and maintained decorum with each other.
Paul instead criticized ex Joshua rival the Cameroonian fighter and described him as "ridiculous" after the Cameroonian rejected a fight offer.
Taking Aim at Fury
Anthony Joshua, meanwhile, targeted British opponent Tyson Fury - and rejected a £1m bet 'The Gypsy King' claims he will make on a Paul win.
"Jake Paul outshines Tyson Fury - he showed up," the boxer stated.
"I give him credit for that."
Legitimate Fighter
Despite declaring he will hurt Jake Paul, Anthony Joshua chose not to talk badly about his rival's pugilistic talent.
"Jake is a serious fighter," he said.
Jake Paul's Background
Jake Paul - who initially became famous on the Disney Channel - has primarily boxed MMA fighters or past-their-prime fighters since turning professional.
He was defeated by Briton Tommy Fury in 2023.
Financial Attraction
Still, the relative newcomer continues to be one of the sport's biggest commercial attractions, consistently making substantial earnings.
Prediction and Belief
The 28 year old predicted a stoppage in rounds four or five and stated he would derail the highly-expected Fury-Joshua bout, which is reportedly under discussion for two years from now.
"The next fight will be me versus Tyson Fury next year," Paul said.
Size Disparity
As both boxers engaged in the usual stare-down, with their size difference on show, it highlighted just how surprising this entire matchup is - and how amazing it is that the fight is truly going ahead.
