Anthony Joshua will face the American YouTuber in an eight-bout match which will be streamed live on Netflix.
Briton Joshua declared he will "dominate completely" the American and "defeat" the American as the combatants came face-to-face to publicize next month's heavyweight fight.
Ex two time world title holder Anthony Joshua faces social media star turned fighter Paul - in what is, by the numbers, a massive disparity - at Miami venue on 19 December.
Boxer's Attitude
"I plan to break his face and break his body up. I aim to demonstrate I'm the better fighter," Joshua, 35 years old, stated.
"I will dominate him completely. That's how fighters think.
"I intend to really want to hurt him. That's my intention."
Respectful Interaction
In spite of these statements, a composed Anthony Joshua and social media star Paul - usually known for his showmanship - exchanged pleasantries and kept it respectful with each other.
Paul instead attacked ex Joshua's opponent Francis Ngannou and called him "ridiculous" after the Cameroonian rejected a bout proposal.
Targeting Fury
Joshua, meanwhile, criticized UK rival Fury - and rejected a million-pound wager 'Tyson Fury' says he will place on a Paul victory.
"[Paul] is better than Fury - he's actually sitting here," the boxer commented.
"I respect him for that."
Legitimate Opponent
Despite saying he intends to damage his opponent, Joshua chose not to comment unfavorably about his rival's pugilistic talent.
"Jake Paul is a credible opponent," he remarked.
Paul's History
Paul - who initially became famous on the television network - has mostly fought MMA fighters or past-their-prime fighters since entering professional boxing.
He was defeated by British fighter Fury in last year.
Financial Attraction
However, the novice remains one of the sport's largest financial successes, frequently receiving substantial paydays.
Prediction and Confidence
The 28 year old predicted a knockout win in the fourth or fifth round and stated he would stop the much-anticipated Fury-Joshua bout, which is allegedly in the works for 2026.
"It will be me versus Tyson Fury in the coming year," Jake Paul declared.
Size Difference
As the two fighters engaged in the usual confrontation, with their height and weight contrast evident, it emphasized just how unlikely this entire matchup is - and how astonishing it is that the bout is really proceeding.
