The British boxer will face Jake Paul in an eight-bout match which will be streamed in real-time on Netflix.
British boxer Joshua declared he will "overwhelm entirely" the American and "defeat" the American as the pair confronted each other to promote the upcoming heavyweight fight.
Ex two-time world heavyweight champion Anthony Joshua battles YouTuber-turned-boxer Paul - in what is, on paper, a huge uneven pairing - at Miami's venue on 19 December.
Boxer's Mindset
"I'm going to injure his face and hurt his body. I'm here to prove I'm the better fighter," the British boxer, 35, declared.
"I'll stamp all over him. That's how fighters think.
"I will seriously aim to hurt him. That's my goal."
Civil Interaction
Despite these statements, a relaxed Joshua and internet personality Paul - usually recognized for his theatrics - exchanged pleasantries and maintained decorum with each other.
Paul rather criticized ex Joshua's opponent Francis Ngannou and described him as "a joke" after Ngannou turned down a match opportunity.
Targeting Tyson Fury
Anthony Joshua, meanwhile, criticized UK rival Tyson Fury - and declined a large bet 'The Gypsy King' states he will put on a Paul win.
"[Paul] is better than Fury - he showed up," Joshua commented.
"I give him credit for that."
Serious Opponent
Despite declaring he will punish Paul, Anthony Joshua chose not to comment unfavorably about his rival's fighting skills.
"Jake is a credible opponent," he remarked.
Paul's Background
Jake Paul - who initially became famous on the television network - has mainly fought mixed martial artists or declining opponents since turning professional.
He was defeated by British fighter Tommy Fury in last year.
Commercial Attraction
Nevertheless, the relative newcomer remains one of the sport's largest money-making draws, consistently making huge paydays.
Prediction and Belief
The 28 year old anticipated a knockout win in round four or five and asserted he would derail the much-anticipated match between Joshua and Fury, which is reportedly being planned for 2026.
"It's going to be my match with Fury next year," Paul stated.
Size Difference
As the two fighters met for the usual confrontation, with their physical disparity evident, it highlighted just how improbable this entire matchup is - and how astonishing it is that the match is really proceeding.
