The British boxer will face Jake Paul in an eight-bout match which will be broadcast live on the streaming platform.
Briton Joshua declared he will "dominate completely" the American and "overpower" the American as the pair confronted each other to publicize the upcoming heavyweight fight.
Former two-time unified boxing king Anthony Joshua meets YouTuber-turned-boxer Jake Paul - in what is, by the numbers, a huge uneven pairing - at Miami's arena on December 19th.
"I plan to break his face and hurt his body. My goal is to show I'm superior," Joshua, 35, said.
"I will dominate him completely. That's how fighters think.
"I intend to seriously aim to cause him pain. That's my intention."
In spite of those words, a composed Anthony Joshua and internet personality Jake Paul - normally famous for his dramatics - were respectful and remained civil with each other.
Paul rather criticized former Joshua opponent Francis Ngannou and described him as "a joke" after the Cameroonian turned down a match opportunity.
Joshua, meanwhile, targeted British opponent Tyson Fury - and refused a million-pound wager 'The Gypsy King' claims he will make on a Paul win.
"[Paul] outshines Tyson Fury - he showed up," Joshua commented.
"I respect him for that."
In spite of declaring he will punish Paul, Joshua chose not to comment unfavorably about his rival's boxing ability.
"Jake is a serious fighter," he said.
Paul - who first rose to fame on the television network - has mainly boxed MMA fighters or faded names since entering professional boxing.
He was defeated by British fighter Tommy Fury in 2023.
However, the novice continues to be one of the sport's biggest money-making draws, frequently receiving massive earnings.
The 28-year-old anticipated a KO victory in rounds four or five and stated he would stop the long-awaited match between Joshua and Fury, which is apparently in the works for two years from now.
"The next fight will be me versus Tyson Fury in the coming year," Jake Paul said.
As the two fighters participated in the traditional stare-down, with their physical disparity clearly visible, it highlighted just how improbable this complete situation is - and how astonishing it is that the fight is really proceeding.
