The British boxer is set to fight Jake Paul in an eight round fight which will be streamed in real-time on the streaming platform.
Briton Joshua said he will "overwhelm entirely" the American and "break" the American as the combatants confronted each other to publicize the upcoming boxing match.
Ex two-time world title holder Anthony Joshua meets YouTuber-turned-boxer Jake Paul - in what is, by the numbers, a huge disparity - at Miami Kaseya Center on 19 December.
Fighter's Mentality
"I'm going to break his face and break his body up. My goal is to show my superiority," the British boxer, 35 years old, stated.
"I will dominate him completely. That's the boxer's mindset.
"I intend to genuinely try to injure him. That's my goal."
Civil Exchange
Despite such comments, a relaxed Joshua and social media star Jake Paul - usually recognized for his dramatics - exchanged pleasantries and kept it respectful with each other.
Jake Paul instead targeted former Joshua opponent the Cameroonian fighter and labeled him "not serious" after the Cameroonian declined a match opportunity.
Taking Aim at Tyson Fury
Anthony Joshua, in the meantime, targeted British rival Tyson Fury - and declined a £1m bet 'Tyson Fury' states he will put on a Paul victory.
"[Paul] outshines Tyson Fury - he's present here," Joshua said.
"I respect him for that."
Serious Fighter
Despite saying he intends to punish Paul, Anthony Joshua refused to talk badly about his opponent's fighting skills.
"Jake is a serious fighter," he said.
Paul's History
Paul - who first rose to fame on the Disney Channel - has primarily boxed mixed martial artists or faded names since entering professional boxing.
He was defeated by British fighter Fury in last year.
Commercial Success
Nevertheless, the inexperienced fighter remains one of the sport's largest money-making draws, regularly earning massive earnings.
Prediction and Confidence
The 28-year-old predicted a KO victory in rounds four or five and claimed he would stop the much-anticipated Fury-Joshua bout, which is apparently being planned for 2026.
"It will be myself against Tyson Fury in the coming year," Jake Paul declared.
Size Difference
As Joshua and Paul met for the traditional stare-down, with their height and weight contrast evident, it drove home just how surprising this whole event is - and how astonishing it is that the fight is actually proceeding.
