Anthony Joshua prepares to battle the American YouTuber in an eight round match which will be broadcast live on Netflix.
Briton Joshua said he will "stamp all over" the American and "defeat" the American as the pair met personally to promote the upcoming boxing match.
Former twice world boxing king Anthony Joshua faces social media star turned fighter Paul - in what is, theoretically, a mammoth uneven pairing - at Miami arena on 19 December.
Fighter's Mindset
"I'm going to injure his face and damage his physique. I'm here to prove I'm the better fighter," the British boxer, 35 years old, said.
"I will dominate him completely. That's a fighter's mentality.
"I will seriously aim to injure him. That's my goal."
Civil Exchange
Despite these statements, a relaxed Joshua and internet personality Jake Paul - usually known for his theatrics - shared friendly words and maintained decorum with each other.
Paul instead attacked former Joshua's rival the Cameroonian fighter and labeled him "ridiculous" after Ngannou declined a match opportunity.
Targeting Fury
Joshua, at the same time, took aim at UK rival Tyson Fury - and refused a million-pound wager 'Tyson Fury' claims he will make on a Paul win.
"[Paul] is better than Fury - he's present here," Joshua commented.
"I respect him for that."
Serious Opponent
Despite declaring he will damage his opponent, Anthony Joshua declined to speak negatively about his opponent's fighting skills.
"Jake is a credible opponent," he said.
Paul's Background
Paul - who originally gained popularity on the Disney Channel - has primarily boxed mixed martial artists or declining opponents since becoming pro.
He lost to British fighter Tommy Fury in last year.
Financial Attraction
However, the relative newcomer continues to be one of the sport's largest financial successes, consistently making huge paydays.
Prediction and Confidence
The 28-year-old predicted a KO victory in rounds four or five and stated he would prevent the highly-expected Fury-Joshua bout, which is allegedly in the works for two years from now.
"It's going to be me versus Tyson Fury in the coming year," Paul said.
Physical Difference
As Joshua and Paul participated in the usual face-off, with their size difference on show, it highlighted just how improbable this entire matchup is - and how remarkable it is that the match is really going ahead.
