The British boxer will face Jake Paul in an eight round fight which will be streamed live on the streaming platform.
British boxer Joshua stated he will "dominate completely" Jake Paul and "defeat" the American as the pair came face-to-face to promote the upcoming heavyweight fight.
Former two-time unified heavyweight champion Joshua battles social media star turned fighter Paul - in what is, by the numbers, a massive mismatch - at Miami arena on 19 December.
Fighter's Attitude
"I plan to damage his features and damage his physique. I aim to demonstrate my superiority," Joshua, 35 years old, said.
"I will dominate him completely. That's a fighter's mentality.
"I will really want to hurt him. That's my intention."
Civil Interaction
In spite of these statements, a calm Joshua and internet personality Jake Paul - normally famous for his theatrics - shared friendly words and maintained decorum with each other.
Paul rather attacked ex Joshua opponent Francis Ngannou and described him as "ridiculous" after the Cameroonian turned down a match opportunity.
Taking Aim at Fury
Anthony Joshua, meanwhile, targeted UK opponent Tyson Fury - and declined a million-pound wager 'Tyson Fury' says he will place on a Paul win.
"Jake Paul outshines Tyson Fury - he showed up," Joshua said.
"I acknowledge that."
Serious Opponent
Despite saying he intends to hurt Jake Paul, Anthony Joshua declined to comment unfavorably about his opponent's boxing ability.
"Jake is a serious fighter," he said.
Jake Paul's Background
Paul - who first rose to fame on the television network - has mostly fought mixed martial artists or past-their-prime fighters since entering professional boxing.
He was defeated by British fighter Tommy Fury in last year.
Financial Success
However, the relative newcomer remains one of the sport's largest commercial attractions, frequently receiving huge financial rewards.
Forecast and Confidence
The 28 year old anticipated a KO victory in round four or five and claimed he would derail the long-awaited match between Joshua and Fury, which is apparently being planned for 2026.
"It will be myself against Tyson Fury next year," Paul said.
Size Difference
As the two fighters engaged in the customary stare-down, with their physical disparity clearly visible, it highlighted just how improbable this complete situation is - and how astonishing it is that the bout is truly going ahead.
