The British boxer will face the American YouTuber in an eight-bout match which will be broadcast live on the streaming platform.
Briton Joshua stated he will "stamp all over" the American and "break" the American as the two fighters confronted each other to build hype for next month's boxing match.
Ex two-time unified title holder Anthony Joshua battles YouTuber-turned-boxer Paul - in what is, theoretically, a huge uneven pairing - at Miami's venue on 19 December.
Fighter's Attitude
"I plan to break his face and hurt his body. My goal is to show I'm superior," Joshua, 35 years old, stated.
"I plan to overwhelm him. That's the boxer's mindset.
"I intend to really want to hurt him. That's what I want to do."
Civil Exchange
In spite of those words, a calm Joshua and internet personality Paul - normally known for his dramatics - exchanged pleasantries and kept it respectful with each other.
Paul instead targeted ex Joshua's rival the Cameroonian fighter and described him as "not serious" after Ngannou rejected a match opportunity.
Targeting Fury
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 is superior to Tyson Fury - he showed up," the boxer stated.
"I respect him for that."
Serious Fighter
Despite declaring he will damage his opponent, Joshua chose not to talk badly about his opponent's fighting skills.
"Jake Paul is a serious fighter," he stated.
Paul's History
Paul - who originally gained popularity on the Disney Channel - has mainly fought MMA fighters or faded names since becoming pro.
He lost to Briton Fury in 2023.
Financial Success
Still, the relative newcomer is still one of boxing's biggest commercial attractions, regularly earning huge financial rewards.
Forecast and Belief
The 28-year-old forecast a KO victory in round four or five and stated he would derail the long-awaited Fury-Joshua bout, which is allegedly in the works for 2026.
"It's going to be me versus Tyson Fury in the coming year," Paul said.
Physical Difference
As both boxers met for the traditional face-off, with their size difference on show, it highlighted just how improbable this entire matchup is - and how amazing it is that the match is actually proceeding.
