The British boxer will face Jake Paul in an eight-bout match which will be broadcast in real-time on Netflix.
British boxer Joshua said he will "dominate completely" Jake Paul and "overpower" the American as the pair came face-to-face to build hype for the upcoming bout.
Former twice world boxing king Joshua faces social media star turned fighter Paul - in what is, theoretically, a huge disparity - at Miami's arena on 19 December.
Boxer's Mentality
"I will break his face and break his body up. I aim to demonstrate I'm superior," the British boxer, 35, stated.
"I plan to overwhelm him. That's the boxer's mindset.
"I'm going to genuinely try to injure him. That's what I want to do."
Civil Exchange
In spite of these statements, a calm Joshua and social media star Paul - normally recognized for his theatrics - were respectful and remained civil with each other.
Jake Paul rather targeted ex Joshua rival the Cameroonian fighter and called him "a joke" after Ngannou turned down a match opportunity.
Targeting Fury
Anthony Joshua, at the same time, criticized British opponent Tyson Fury - and declined a large bet 'The Gypsy King' states he will put on a Paul win.
"[Paul] is better than Tyson Fury - he's present here," Joshua stated.
"I respect him for that."
Serious Fighter
Despite saying he intends to hurt Jake Paul, Anthony Joshua chose not to talk badly about his rival's pugilistic talent.
"Jake Paul is a serious fighter," he stated.
Paul's History
Paul - who originally gained popularity on the Disney Channel - has mostly boxed mixed martial artists or faded names since becoming pro.
He was defeated by British fighter Tommy Fury in last year.
Financial Attraction
However, the inexperienced fighter is still one of the sport's greatest financial successes, consistently making huge financial rewards.
Prediction and Belief
The 28-year-old forecast a knockout win in rounds four or five and stated he would prevent the much-anticipated match between Joshua and Fury, which is apparently under discussion for two years from now.
"It will be me versus Tyson Fury in the coming year," Jake Paul said.
Physical Disparity
As both boxers engaged in the customary stare-down, with their height and weight contrast on show, it drove home just how surprising this entire matchup is - and how amazing it is that the fight is truly happening.
