The British boxer will face the American YouTuber in an eight-round match which will be streamed live on Netflix.
Briton Joshua declared he will "stamp all over" the American and "overpower" the American as the pair confronted each other to publicize the upcoming heavyweight fight.
Ex two time world title holder Joshua faces social media star turned fighter Paul - in what is, by the numbers, a huge mismatch - at Miami's Kaseya Center on 19 December.
Boxer's Attitude
"I'm going to damage his features and hurt his body. I aim to demonstrate I'm the better fighter," Joshua, 35, said.
"I plan to overwhelm him. That's how fighters think.
"I will genuinely try to hurt him. That's my intention."
Respectful Interaction
In spite of such comments, a calm Joshua and social media star Jake Paul - normally known for his showmanship - shared friendly words and kept it respectful with each other.
Paul rather targeted former Joshua opponent the Cameroonian fighter and called him "a joke" after the Cameroonian declined a bout proposal.
Taking Aim at Tyson Fury
Joshua, meanwhile, targeted UK rival Fury - and rejected a large bet 'Tyson Fury' says he will place on a victory for Paul.
"Jake Paul is superior to Fury - he's actually sitting here," Joshua stated.
"I acknowledge that."
Legitimate Opponent
In spite of saying he intends to damage his opponent, Anthony Joshua refused to comment unfavorably about his rival's pugilistic talent.
"Jake is a serious fighter," he stated.
Jake Paul's History
Jake Paul - who first rose to fame on the Disney Channel - has mostly fought mixed martial artists or past-their-prime fighters since becoming pro.
He lost to British fighter Fury in last year.
Financial Attraction
Still, the novice continues to be one of the sport's largest financial successes, frequently receiving huge financial rewards.
Prediction and Belief
The 28-year-old anticipated a KO victory in round four or five and claimed he would derail the long-awaited match between Joshua and Fury, which is allegedly being planned for two years from now.
"The next fight will be my match with Fury in the coming year," Paul declared.
Size Difference
As both boxers met for the customary face-off, with their physical disparity evident, it drove home just how surprising this whole event is - and how remarkable it is that the match is truly happening.
