The British boxer is set to fight Jake Paul in an eight-round match which will be streamed live on the streaming platform.
British boxer Joshua declared he will "overwhelm entirely" the American and "break" his opponent as the two fighters came face-to-face to build hype for the upcoming bout.
Ex two time unified boxing king Anthony Joshua faces social media star turned fighter Paul - in what is, theoretically, a massive uneven pairing - at Miami's arena on 19 December.
Fighter's Mentality
"I will damage his features and hurt his body. I'm here to prove my superiority," the British boxer, 35 years old, declared.
"I will dominate him completely. That's a fighter's mentality.
"I will seriously aim to injure him. That's what I want to do."
Civil Exchange
In spite of such comments, a calm Joshua and social media star Paul - typically recognized for his theatrics - were respectful and kept it respectful with each other.
Jake Paul rather attacked former Joshua's opponent Francis Ngannou and labeled him "not serious" after Ngannou turned down a match opportunity.
Targeting Fury
Anthony Joshua, meanwhile, took aim at British rival Tyson Fury - and rejected a million-pound wager 'Tyson Fury' states he will put on a victory for Paul.
"[Paul] outshines Fury - he showed up," Joshua said.
"I give him credit for that."
Serious Opponent
Despite declaring he will damage his opponent, Joshua refused to talk badly about his opponent's pugilistic talent.
"Jake is a legitimate boxer," he said.
Paul's Background
Paul - who originally gained popularity on the Disney Channel - has primarily boxed MMA fighters or faded names since entering professional boxing.
He was defeated by British fighter Fury in last year.
Financial Attraction
Nevertheless, the relative newcomer is still one of boxing's greatest money-making draws, frequently receiving substantial paydays.
Forecast and Belief
The 28 year old anticipated a stoppage in rounds four or five and stated he would prevent the long-awaited Fury-Joshua bout, which is allegedly being planned for two years from now.
"It's going to be myself against Tyson Fury next year," Paul stated.
Size Disparity
As both boxers met for the usual stare-down, with their height and weight contrast on show, it highlighted just how improbable this entire matchup is - and how remarkable it is that the fight is truly going ahead.
