Anthony Joshua prepares to battle Jake Paul in an eight round fight which will be streamed in real-time on the streaming platform.
Briton Joshua said he will "stamp all over" the American and "defeat" the American as the pair met personally to publicize the upcoming heavyweight fight.
Ex two time world title holder Joshua meets YouTuber-turned-boxer Jake Paul - in what is, theoretically, a massive mismatch - at Miami's arena on 19 December.
Boxer's Attitude
"I'm going to damage his features and break his body up. I aim to demonstrate my superiority," the British boxer, 35, declared.
"I plan to overwhelm him. That's how fighters think.
"I will really want to cause him pain. That's what I want to do."
Respectful Exchange
Despite those words, a calm Joshua and social media star Jake Paul - typically famous for his dramatics - were respectful and remained civil with each other.
Paul instead targeted former Joshua's rival Francis Ngannou and called him "ridiculous" after the Cameroonian declined a bout proposal.
Targeting Fury
Joshua, at the same time, took aim at British rival Tyson Fury - and declined a large bet 'Tyson Fury' states he will put on a Paul win.
"[Paul] outshines Fury - he's actually sitting here," Joshua said.
"I give him credit for that."
Serious Fighter
Despite stating he plans to punish Paul, Anthony Joshua declined to speak negatively about his rival's boxing ability.
"Jake is a legitimate boxer," he said.
Paul's Background
Jake Paul - who originally gained popularity on the Disney Channel - has primarily boxed MMA fighters or faded names since turning professional.
He was defeated by British fighter Tommy Fury in last year.
Financial Attraction
However, the relative newcomer continues to be one of the sport's largest financial successes, frequently receiving massive financial rewards.
Prediction and Belief
The 28 year old anticipated a stoppage in the fourth or fifth round and stated he would derail the much-anticipated Fury-Joshua bout, which is apparently being planned for 2026.
"The next fight will be myself against Tyson Fury next year," Jake Paul declared.
Physical Disparity
As both boxers participated in the traditional stare-down, with their height and weight contrast evident, it emphasized just how surprising this whole event is - and how remarkable it is that the bout is truly proceeding.
