The British boxer will face the American YouTuber in an eight-round fight which will be broadcast in real-time on the streaming platform.
British boxer Joshua said he will "overwhelm entirely" the American and "break" his opponent as the two fighters met personally to publicize next month's heavyweight fight.
Former twice unified title holder Anthony Joshua meets YouTuber-turned-boxer Jake Paul - in what is, by the numbers, a huge disparity - at Miami's arena on 19 December.
Fighter's Mindset
"I plan to damage his features and hurt his body. I'm here to prove I'm the better fighter," the British boxer, 35, declared.
"I will dominate him completely. That's a fighter's mentality.
"I'm going to seriously aim to injure him. That's my intention."
Respectful Exchange
Despite those words, a composed Anthony Joshua and internet personality Jake Paul - usually famous for his showmanship - were respectful and maintained decorum with each other.
Jake Paul rather targeted ex Joshua opponent Francis Ngannou and labeled him "a joke" after the Cameroonian rejected a fight offer.
Taking Aim at Tyson Fury
Joshua, meanwhile, targeted UK opponent Tyson Fury - and rejected a £1m bet 'Tyson Fury' claims he will make on a Paul victory.
"Jake Paul is superior to Tyson Fury - he's present here," the boxer stated.
"I acknowledge that."
Legitimate Fighter
Despite declaring he will hurt Jake Paul, Joshua chose not to speak negatively about his rival's fighting skills.
"Jake Paul is a credible opponent," he said.
Jake Paul's Background
Paul - who first rose to fame on the television network - has mainly fought mixed martial artists or declining opponents since becoming pro.
He lost to British fighter Tommy Fury in last year.
Financial Success
Still, the novice continues to be one of the sport's biggest money-making draws, consistently making massive financial rewards.
Forecast and Confidence
The 28 year old forecast a KO victory in rounds four or five and claimed he would derail the much-anticipated match between Joshua and Fury, which is reportedly under discussion for two years from now.
"It's going to be me versus Tyson Fury in the coming year," Jake Paul stated.
Physical Disparity
As both boxers met for the traditional face-off, with their physical disparity on show, it highlighted just how surprising this whole event is - and how astonishing it is that the match is truly going ahead.
