The British boxer will face the American YouTuber in an eight round match which will be broadcast in real-time on Netflix.
Briton Joshua said he will "stamp all over" the American and "overpower" his opponent as the two fighters came face-to-face to promote the upcoming bout.
Ex twice world heavyweight champion Joshua faces YouTuber-turned-boxer Paul - in what is, by the numbers, a mammoth mismatch - at Miami venue on 19 December.
Boxer's Mentality
"I will break his face and hurt his body. I aim to demonstrate I'm superior," the British boxer, 35 years old, stated.
"I will dominate him completely. That's a fighter's mentality.
"I'm going to genuinely try to hurt him. That's my goal."
Respectful Exchange
Despite such comments, a composed Joshua and internet personality Jake Paul - normally famous for his showmanship - shared friendly words and kept it respectful with each other.
Jake Paul rather attacked ex Joshua's rival the Cameroonian fighter and labeled him "not serious" after Ngannou turned down a fight offer.
Taking Aim at Fury
Anthony Joshua, meanwhile, targeted British opponent Fury - and refused a large bet 'The Gypsy King' states he will put on a Paul win.
"Jake Paul is superior to Fury - he's present here," Joshua said.
"I acknowledge that."
Serious Opponent
Despite saying he intends to damage his opponent, Joshua refused to talk badly about his opponent's boxing ability.
"Jake is a credible opponent," he said.
Jake Paul's History
Jake Paul - who first rose to fame on the Disney Channel - has mostly fought mixed martial artists or faded names since entering professional boxing.
He lost to British fighter Tommy Fury in last year.
Commercial Success
Still, the relative newcomer continues to be one of the sport's largest commercial attractions, consistently making massive earnings.
Prediction and Confidence
The 28 year old anticipated a stoppage in the fourth or fifth round and claimed he would stop the highly-expected match between Joshua and Fury, which is reportedly in the works for two years from now.
"It's going to be myself against Tyson Fury in the coming year," Paul said.
Size Difference
As Joshua and Paul participated in the usual face-off, with their height and weight contrast clearly visible, it emphasized just how unlikely this whole event is - and how remarkable it is that the fight is actually happening.
