The British boxer will face Jake Paul in an eight-round fight which will be broadcast live on the streaming platform.
Briton Joshua said he will "stamp all over" Jake Paul and "overpower" his opponent as the pair came face-to-face to promote next month's bout.
Former two time unified boxing king Anthony Joshua faces YouTuber-turned-boxer Paul - in what is, theoretically, a massive mismatch - at Miami arena on 19 December.
Fighter's Attitude
"I plan to break his face and break his body up. My goal is to show I'm the better fighter," Joshua, 35 years old, declared.
"I plan to overwhelm him. That's the boxer's mindset.
"I will seriously aim to hurt him. That's my intention."
Respectful Interaction
Despite these statements, a relaxed Anthony Joshua and internet personality Paul - typically known for his showmanship - shared friendly words and maintained decorum with each other.
Jake Paul rather targeted ex Joshua's opponent the Cameroonian fighter and described him as "ridiculous" after Ngannou declined a fight offer.
Targeting Tyson Fury
Anthony Joshua, at the same time, criticized British rival Fury - and declined a £1m bet 'The Gypsy King' says he will place on a victory for Paul.
"[Paul] outshines Fury - he showed up," Joshua said.
"I give him credit for that."
Legitimate Fighter
Despite saying he intends to punish Paul, Joshua refused to talk badly about his opponent's pugilistic talent.
"Jake Paul is a credible opponent," he stated.
Paul's Background
Jake Paul - who first rose to fame on the television network - has mainly fought mixed martial artists or faded names since entering professional boxing.
He lost to British fighter Tommy Fury in last year.
Commercial Attraction
Nevertheless, the novice remains one of the sport's largest financial successes, regularly earning huge financial rewards.
Forecast and Belief
The 28-year-old forecast a knockout win in rounds four or five and claimed he would stop the highly-expected Joshua–Fury fight, which is apparently in the works for two years from now.
"The next fight will be my match with Fury in the coming year," Paul said.
Physical Difference
As both boxers met for the traditional stare-down, with their physical disparity on show, it highlighted just how improbable this complete situation is - and how amazing it is that the match is really proceeding.
