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 "dominate completely" the American and "defeat" his opponent as the pair met personally to build hype for next month's bout.
Former twice world title holder Anthony Joshua meets YouTuber-turned-boxer Paul - in what is, theoretically, a mammoth disparity - at Miami Kaseya Center on 19 December.
Fighter's Mindset
"I plan to break his face and damage his physique. My goal is to show my superiority," the British boxer, 35, stated.
"I will dominate him completely. That's how fighters think.
"I'm going to really want to cause him pain. That's my goal."
Civil Interaction
Despite these statements, a calm Anthony Joshua and social media star Paul - usually recognized for his showmanship - shared friendly words and kept it respectful with each other.
Paul instead targeted former Joshua rival Francis Ngannou and labeled him "not serious" after Ngannou turned down a fight offer.
Targeting Tyson Fury
Joshua, in the meantime, targeted British rival Fury - and refused a million-pound wager 'Tyson Fury' claims he will make on a Paul win.
"[Paul] outshines Fury - he's present here," the boxer commented.
"I respect him for that."
Serious Fighter
In spite of saying he intends to punish Paul, Joshua declined to talk badly about his rival's pugilistic talent.
"Jake Paul is a serious fighter," he remarked.
Paul's Background
Paul - who originally gained popularity on the television network - has mainly boxed mixed martial artists or declining opponents since entering professional boxing.
He lost to Briton Fury in 2023.
Commercial Success
However, the relative newcomer continues to be one of the sport's greatest commercial attractions, frequently receiving substantial financial rewards.
Prediction and Confidence
The 28 year old anticipated a knockout win in rounds four or five and asserted he would derail the much-anticipated match between Joshua and Fury, which is allegedly in the works for two years from now.
"It will be myself against Tyson Fury in the coming year," Jake Paul stated.
Physical Difference
As the two fighters engaged in the usual face-off, with their size difference on show, it emphasized just how surprising this entire matchup is - and how remarkable it is that the match is actually happening.
