The British boxer is set to fight the American YouTuber in an eight round match which will be streamed live on the streaming platform.
Briton Anthony Joshua declared he will "stamp all over" the American and "break" the American as the two fighters came face-to-face to promote the upcoming bout.
Former twice world title holder Joshua battles social media star turned fighter Jake Paul - in what is, theoretically, a mammoth disparity - at Miami Kaseya Center on 19 December.
Boxer's Mentality
"I will break his face and break his body up. I aim to demonstrate I'm the better fighter," Joshua, 35, declared.
"I'll stamp all over him. That's the boxer's mindset.
"I will really want to injure him. That's what I want to do."
Respectful Exchange
Despite such comments, a composed Anthony Joshua and internet personality Jake Paul - usually known for his dramatics - shared friendly words and kept it respectful with each other.
Paul rather attacked ex Joshua's opponent Francis Ngannou and described him as "ridiculous" after Ngannou rejected a match opportunity.
Targeting Tyson Fury
Joshua, meanwhile, took aim at British rival Fury - and refused a large bet 'The Gypsy King' states he will put on a victory for Paul.
"[Paul] is better than Fury - he showed up," the boxer commented.
"I acknowledge that."
Legitimate Opponent
Despite declaring he will hurt Jake Paul, Joshua chose not to speak negatively about his opponent's pugilistic talent.
"Jake Paul is a credible opponent," he remarked.
Paul's Background
Jake Paul - who first rose to fame on the television network - has mostly fought MMA fighters or declining opponents since becoming pro.
He was defeated by British fighter Fury in last year.
Financial Success
Still, the inexperienced fighter continues to be one of the sport's greatest commercial attractions, regularly earning huge paydays.
Prediction and Belief
The 28 year old forecast a knockout win in round four or five and asserted he would derail the much-anticipated Joshua–Fury fight, which is reportedly under discussion for 2026.
"It will be myself against Tyson Fury next year," Paul declared.
Physical Disparity
As the two fighters met for the usual stare-down, with their physical disparity evident, it emphasized just how improbable this whole event is - and how amazing it is that the fight is actually happening.
