The British boxer is set to fight the American YouTuber in an eight round fight which will be shown in real-time on Netflix.
Briton Joshua said he will "stamp all over" the American and "defeat" the American as the two fighters met personally to build hype for next month's boxing match.
Ex two-time unified heavyweight champion Joshua meets social media star turned fighter Paul - in what is, theoretically, a massive disparity - at Miami's venue on 19 December.
Fighter's Attitude
"I'm going to injure his face and break his body up. I aim to demonstrate I'm the better fighter," the British boxer, 35, declared.
"I'll stamp all over him. That's the boxer's mindset.
"I will genuinely try to cause him pain. That's my goal."
Respectful Interaction
In spite of these statements, a composed Joshua and internet personality Paul - typically famous for his showmanship - were respectful and kept it respectful with each other.
Paul rather attacked former Joshua rival Francis Ngannou and described him as "a joke" after Ngannou declined a fight offer.
Targeting Fury
Joshua, at the same time, targeted British opponent Fury - and declined a large bet 'Tyson Fury' states he will put on a Paul victory.
"[Paul] outshines Fury - he's actually sitting here," Joshua stated.
"I respect him for that."
Serious Opponent
In spite of saying he intends to hurt Jake Paul, Anthony Joshua chose not to comment unfavorably about his rival's pugilistic talent.
"Jake Paul is a serious fighter," he remarked.
Jake Paul's Background
Paul - who initially became famous on the television network - has mainly boxed MMA fighters or declining opponents since becoming pro.
He was defeated by British fighter Fury in 2023.
Commercial Success
Still, the novice is still one of boxing's largest commercial attractions, consistently making huge financial rewards.
Prediction and Confidence
The 28-year-old predicted a KO victory in the fourth or fifth round and claimed he would stop the highly-expected Fury-Joshua bout, which is apparently under discussion for two years from now.
"It will be me versus Tyson Fury next year," Paul declared.
Size Disparity
As both boxers participated in the customary stare-down, with their physical disparity clearly visible, it drove home just how improbable this whole event is - and how remarkable it is that the fight is truly happening.
