The British boxer will face the American YouTuber in an eight-round contest which will be broadcast live on Netflix.
British boxer Joshua said he will "stamp all over" the American and "defeat" his opponent as the pair came face-to-face to build hype for the upcoming boxing match.
Ex two-time unified title holder Joshua faces social media star turned fighter Paul - in what is, by the numbers, a huge uneven pairing - at Miami arena on 19 December.
Fighter's Mindset
"I'm going to injure his face and damage his physique. I aim to demonstrate my superiority," Joshua, 35 years old, declared.
"I plan to overwhelm him. That's a fighter's mentality.
"I intend to genuinely try to cause him pain. That's what I want to do."
Civil Exchange
In spite of these statements, a calm Anthony Joshua and internet personality Paul - typically famous for his showmanship - exchanged pleasantries and maintained decorum with each other.
Jake Paul rather criticized former Joshua's opponent the Cameroonian fighter and labeled him "not serious" after the Cameroonian rejected a bout proposal.
Taking Aim at Tyson Fury
Joshua, meanwhile, targeted British opponent Fury - and refused a £1m bet 'Tyson Fury' says he will place on a victory for Paul.
"Jake Paul is better than Tyson Fury - he showed up," Joshua stated.
"I respect him for that."
Serious Fighter
In spite of stating he plans to punish Paul, Anthony Joshua refused to speak negatively about his rival's pugilistic talent.
"Jake is a serious fighter," he stated.
Paul's Background
Paul - who originally gained popularity on the television network - has mainly boxed mixed martial artists or past-their-prime fighters since entering professional boxing.
He was defeated by British fighter Fury in last year.
Commercial Success
However, the novice is still one of boxing's largest money-making draws, consistently making massive earnings.
Prediction and Belief
The 28-year-old forecast a stoppage in rounds four or five and stated he would prevent the highly-expected Fury-Joshua bout, which is apparently being planned for 2026.
"The next fight will be me versus Tyson Fury in the coming year," Paul stated.
Physical Difference
As Joshua and Paul met for the customary stare-down, with their physical disparity on show, it drove home just how improbable this entire matchup is - and how amazing it is that the match is truly proceeding.
