The British boxer will face the American YouTuber in an eight-bout match which will be broadcast in real-time on the streaming platform.
British boxer Anthony Joshua said he will "overwhelm entirely" the American and "overpower" the American as the combatants came face-to-face to promote next month's heavyweight fight.
Ex two-time unified heavyweight champion Anthony Joshua meets YouTuber-turned-boxer Paul - in what is, by the numbers, a massive disparity - at Miami's arena on 19 December.
Fighter's Attitude
"I will damage his features and hurt his body. My goal is to show I'm the better fighter," the British boxer, 35, declared.
"I will dominate him completely. That's how fighters think.
"I'm going to seriously aim to injure him. That's what I want to do."
Civil Interaction
Despite such comments, a relaxed Anthony Joshua and internet personality Jake Paul - typically famous for his showmanship - shared friendly words and remained civil with each other.
Paul instead criticized ex Joshua opponent Francis Ngannou and called him "ridiculous" after Ngannou turned down a fight offer.
Targeting Tyson Fury
Anthony Joshua, at the same time, targeted British rival Fury - and rejected a large bet 'The Gypsy King' says he will place on a victory for Paul.
"[Paul] is superior to Fury - he's present here," the boxer commented.
"I respect him for that."
Legitimate Fighter
Despite stating he plans to damage his opponent, Anthony Joshua refused to speak negatively about his rival's fighting skills.
"Jake Paul is a legitimate boxer," he stated.
Jake Paul's Background
Jake Paul - who first rose to fame on the television network - has mainly fought mixed martial artists or past-their-prime fighters since turning professional.
He lost to British fighter Tommy Fury in last year.
Financial Attraction
However, the inexperienced fighter is still one of the sport's biggest commercial attractions, frequently receiving huge earnings.
Prediction and Belief
The 28 year old anticipated a KO victory in rounds four or five and stated he would prevent the much-anticipated match between Joshua and Fury, which is reportedly in the works for two years from now.
"The next fight will be myself against Tyson Fury next year," Jake Paul stated.
Physical Disparity
As the two fighters engaged in the usual confrontation, with their physical disparity on show, it emphasized just how surprising this entire matchup is - and how remarkable it is that the match is really going ahead.
