Anthony Joshua is set to fight the American YouTuber in an eight round contest which will be streamed in real-time on Netflix.
British boxer Joshua said he will "dominate completely" the American and "break" the American as the combatants confronted each other to build hype for the upcoming bout.
Former twice world heavyweight champion Anthony Joshua battles social media star turned fighter Paul - in what is, on paper, a massive disparity - at Miami's Kaseya Center on 19 December.
Fighter's Attitude
"I will damage his features and break his body up. My goal is to show I'm the better fighter," Joshua, 35, said.
"I will dominate him completely. That's the boxer's mindset.
"I intend to seriously aim to hurt him. That's my intention."
Civil Interaction
Despite such comments, a relaxed Anthony Joshua and internet personality Paul - usually recognized for his theatrics - exchanged pleasantries and remained civil with each other.
Jake Paul rather targeted former Joshua rival the Cameroonian fighter and called him "ridiculous" after Ngannou turned down a bout proposal.
Targeting Tyson Fury
Joshua, meanwhile, took aim at British opponent Tyson Fury - and declined a £1m bet 'Tyson Fury' states he will put on a Paul victory.
"Jake Paul is better than Tyson Fury - he's actually sitting here," Joshua stated.
"I acknowledge that."
Legitimate Opponent
Despite declaring he will punish Paul, Joshua refused to comment unfavorably about his opponent's pugilistic talent.
"Jake is a legitimate boxer," he said.
Jake Paul's Background
Paul - who originally gained popularity on the television network - has primarily boxed MMA fighters or faded names since turning professional.
He was defeated by British fighter Fury in last year.
Commercial Attraction
Nevertheless, the relative newcomer remains one of the sport's greatest financial successes, frequently receiving huge paydays.
Prediction and Belief
The 28-year-old anticipated a stoppage in round four or five and asserted he would stop the long-awaited Fury-Joshua bout, which is reportedly in the works for two years from now.
"It's going to be myself against Tyson Fury in the coming year," Jake Paul stated.
Size Disparity
As both boxers met for the traditional face-off, with their physical disparity evident, it emphasized just how unlikely this complete situation is - and how remarkable it is that the fight is truly proceeding.
