The British boxer is set to fight Jake Paul in an eight round fight which will be shown live on Netflix.
Briton Joshua stated he will "overwhelm entirely" the American and "break" the American as the two fighters confronted each other to promote next month's heavyweight fight.
Ex twice world title holder Joshua meets social media star turned fighter Paul - in what is, on paper, a massive uneven pairing - at Miami's Kaseya Center on 19 December.
Fighter's Attitude
"I will break his face and hurt his body. I'm here to prove my superiority," Joshua, 35, stated.
"I will dominate him completely. That's a fighter's mentality.
"I intend to seriously aim to cause him pain. That's my intention."
Civil Exchange
Despite these statements, a calm Anthony Joshua and social media star Jake Paul - usually recognized for his dramatics - were respectful and kept it respectful with each other.
Paul rather attacked ex Joshua's opponent Francis Ngannou and labeled him "a joke" after the Cameroonian rejected a fight offer.
Targeting Tyson Fury
Joshua, in the meantime, targeted British opponent Fury - and refused a million-pound wager 'Tyson Fury' claims he will make on a Paul victory.
"[Paul] outshines Fury - he's present here," the boxer stated.
"I respect him for that."
Legitimate Opponent
In spite of declaring he will hurt Jake Paul, Joshua refused to speak negatively about his rival's pugilistic talent.
"Jake Paul is a credible opponent," he remarked.
Paul's History
Paul - who first rose to fame on the television network - has mostly boxed mixed martial artists or declining opponents since becoming pro.
He lost to Briton Tommy Fury in last year.
Commercial Success
However, the novice is still one of the sport's largest money-making draws, consistently making huge paydays.
Prediction and Belief
The 28-year-old predicted a knockout win in rounds four or five and stated he would derail the long-awaited Fury-Joshua bout, which is reportedly under discussion for two years from now.
"The next fight will be myself against Tyson Fury in the coming year," Paul declared.
Size Difference
As the two fighters participated in the customary stare-down, with their physical disparity evident, it highlighted just how improbable this whole event is - and how astonishing it is that the match is actually proceeding.
