The British boxer will face Jake Paul in an eight round fight which will be streamed in real-time on the streaming platform.
Briton Joshua declared he will "dominate completely" Jake Paul and "break" the American as the combatants confronted each other to publicize next month's heavyweight fight.
Ex twice unified boxing king Joshua meets social media star turned fighter Paul - in what is, on paper, a huge disparity - at Miami Kaseya Center on December 19th.
Boxer's Mentality
"I will damage his features and hurt his body. I'm here to prove I'm the better fighter," the British boxer, 35 years old, stated.
"I plan to overwhelm him. That's a fighter's mentality.
"I will seriously aim to cause him pain. That's my intention."
Respectful Exchange
Despite these statements, a composed Anthony Joshua and internet personality Jake Paul - usually famous for his dramatics - exchanged pleasantries and remained civil with each other.
Jake Paul rather attacked former Joshua rival the Cameroonian fighter and labeled him "ridiculous" after Ngannou turned down a match opportunity.
Taking Aim at Fury
Anthony Joshua, meanwhile, targeted UK opponent Tyson Fury - and rejected a large bet 'The Gypsy King' says he will place on a Paul win.
"Jake Paul is better than Tyson Fury - he's present here," Joshua said.
"I give him credit for that."
Legitimate Opponent
Despite stating he plans to damage his opponent, Joshua refused to speak negatively about his opponent's fighting skills.
"Jake is a serious fighter," he stated.
Paul's Background
Jake Paul - who initially became famous on the Disney Channel - has mainly boxed MMA fighters or faded names since turning professional.
He lost to Briton Tommy Fury in last year.
Commercial Success
Nevertheless, the inexperienced fighter is still one of the sport's greatest commercial attractions, regularly earning huge paydays.
Forecast and Confidence
The 28 year old anticipated a stoppage in the fourth or fifth round and stated he would prevent the highly-expected Fury-Joshua bout, which is apparently in the works for two years from now.
"It will be me versus Tyson Fury in the coming year," Paul declared.
Physical Disparity
As Joshua and Paul participated in the usual face-off, with their height and weight contrast on show, it emphasized just how surprising this complete situation is - and how amazing it is that the bout is really happening.
