The British boxer prepares to battle Jake Paul in an eight round contest which will be broadcast live on the streaming platform.
Briton Joshua declared he will "dominate completely" the American and "defeat" the American as the pair came face-to-face to promote next month's boxing match.
Former twice world title holder Joshua battles YouTuber-turned-boxer Paul - in what is, on paper, a huge uneven pairing - at Miami arena on December 19th.
Boxer's Mentality
"I will injure his face and hurt his body. My goal is to show I'm the better fighter," Joshua, 35, declared.
"I plan to overwhelm him. That's a fighter's mentality.
"I will genuinely try to injure him. That's my intention."
Respectful Exchange
Despite these statements, a relaxed Joshua and social media star Paul - typically famous for his theatrics - were respectful and maintained decorum with each other.
Jake Paul rather targeted former Joshua's rival Francis Ngannou and labeled him "not serious" after Ngannou turned down a match opportunity.
Targeting Fury
Joshua, in the meantime, targeted British opponent Tyson Fury - and rejected a million-pound wager 'The Gypsy King' claims he will make on a victory for Paul.
"[Paul] is better than Tyson Fury - he's present here," the boxer stated.
"I respect him for that."
Serious Opponent
Despite saying he intends to hurt Jake Paul, Anthony Joshua refused to talk badly about his opponent's pugilistic talent.
"Jake is a legitimate boxer," he stated.
Jake Paul's Background
Paul - who originally gained popularity on the Disney Channel - has mostly boxed mixed martial artists or declining opponents since entering professional boxing.
He lost to British fighter Fury in last year.
Financial Success
Still, the relative newcomer is still one of boxing's biggest money-making draws, frequently receiving huge paydays.
Prediction and Confidence
The 28-year-old anticipated a stoppage in rounds four or five and asserted he would prevent the much-anticipated match between Joshua and Fury, which is reportedly under discussion for 2026.
"It will be myself against Tyson Fury next year," Paul said.
Size Difference
As both boxers engaged in the customary face-off, with their size difference on show, it highlighted just how improbable this complete situation is - and how astonishing it is that the bout is truly going ahead.
