Anthony Joshua is set to fight the American YouTuber in an eight round fight which will be broadcast in real-time on the streaming platform.
British boxer Joshua declared he will "stamp all over" Jake Paul and "break" the American as the two fighters met personally to promote next month's heavyweight fight.
Ex two-time unified title holder Joshua meets YouTuber-turned-boxer Paul - in what is, on paper, a mammoth uneven pairing - at Miami's venue on December 19th.
Fighter's Mindset
"I plan to damage his features and damage his physique. I aim to demonstrate I'm superior," Joshua, 35, declared.
"I will dominate him completely. That's a fighter's mentality.
"I will really want to cause him pain. That's what I want to do."
Civil Interaction
Despite such comments, a composed Joshua and internet personality Jake Paul - usually known for his showmanship - shared friendly words and maintained decorum with each other.
Paul instead attacked former Joshua's rival the Cameroonian fighter and called him "not serious" after the Cameroonian turned down a fight offer.
Targeting Fury
Anthony Joshua, meanwhile, took aim at UK rival Tyson Fury - and rejected a £1m bet 'The Gypsy King' claims he will make on a Paul victory.
"[Paul] is better than Fury - he showed up," Joshua commented.
"I give him credit for that."
Legitimate Fighter
Despite stating he plans to punish Paul, Anthony Joshua declined to talk badly about his rival's fighting skills.
"Jake Paul is a credible opponent," he remarked.
Jake Paul's History
Paul - who first rose to fame 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 last year.
Commercial Attraction
Still, the relative newcomer remains one of boxing's greatest financial successes, regularly earning massive financial rewards.
Forecast and Confidence
The 28-year-old predicted a KO victory in round four or five and claimed he would stop the highly-expected Joshua–Fury fight, which is apparently under discussion for two years from now.
"It's going to be me versus Tyson Fury in the coming year," Jake Paul declared.
Size Difference
As Joshua and Paul participated in the customary face-off, with their height and weight contrast on show, it drove home just how improbable this entire matchup is - and how remarkable it is that the bout is truly happening.
