Anthony Joshua will face the American YouTuber in an eight round match which will be shown in real-time on Netflix.
British boxer Joshua declared he will "overwhelm entirely" the American and "overpower" the American as the two fighters met personally to promote the upcoming bout.
Former two time world title holder Anthony Joshua battles YouTuber-turned-boxer Paul - in what is, by the numbers, a mammoth disparity - at Miami's Kaseya Center on 19 December.
Boxer's Attitude
"I will damage his features and damage his physique. I'm here to prove I'm the better fighter," the British boxer, 35, stated.
"I plan to overwhelm him. That's the boxer's mindset.
"I will seriously aim to cause him pain. That's my goal."
Respectful Interaction
Despite such comments, a composed Anthony Joshua and internet personality Paul - normally famous for his showmanship - were respectful and kept it respectful with each other.
Paul rather criticized former Joshua rival Francis Ngannou and described him as "a joke" after the Cameroonian declined a match opportunity.
Targeting Fury
Anthony Joshua, meanwhile, criticized UK opponent Fury - and declined a £1m bet 'The Gypsy King' claims he will make on a victory for Paul.
"[Paul] outshines Tyson Fury - he's actually sitting here," the boxer stated.
"I acknowledge that."
Serious Opponent
In spite of declaring he will hurt Jake Paul, Anthony Joshua declined to talk badly about his opponent's pugilistic talent.
"Jake Paul is a legitimate boxer," he stated.
Paul's History
Jake Paul - who initially became famous on the Disney Channel - has mostly boxed mixed martial artists or faded names since entering professional boxing.
He was defeated by British fighter Tommy Fury in last year.
Commercial Attraction
Still, the inexperienced fighter is still one of boxing's largest financial successes, frequently receiving massive earnings.
Forecast and Confidence
The 28-year-old anticipated a knockout win in rounds four or five and stated he would prevent the much-anticipated 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 stated.
Physical Disparity
As Joshua and Paul participated in the customary face-off, with their size difference clearly visible, it highlighted just how surprising this entire matchup is - and how amazing it is that the match is really going ahead.
