Anthony Joshua will face the American YouTuber in an eight-bout contest which will be shown in real-time on the streaming platform.
British boxer Joshua said he will "dominate completely" the American and "defeat" the American as the pair confronted each other to promote next month's bout.
Former two-time world title holder Joshua faces social media star turned fighter Paul - in what is, on paper, a mammoth disparity - at Miami arena on December 19th.
Fighter's Mindset
"I'm going to damage his features and break his body up. I'm here to prove my superiority," Joshua, 35 years old, stated.
"I'll stamp all over him. That's a fighter's mentality.
"I'm going to really want to hurt him. That's my goal."
Respectful Interaction
Despite these statements, a relaxed Joshua and social media star Jake Paul - typically known for his showmanship - shared friendly words and maintained decorum with each other.
Jake Paul rather criticized ex Joshua rival Francis Ngannou and called him "a joke" after the Cameroonian declined a match opportunity.
Taking Aim at Tyson Fury
Joshua, meanwhile, took aim at British opponent Tyson Fury - and refused a £1m bet 'Tyson Fury' claims he will make on a Paul victory.
"Jake Paul outshines Tyson Fury - he's actually sitting here," Joshua said.
"I acknowledge that."
Legitimate Fighter
In spite of declaring he will hurt Jake Paul, Anthony Joshua refused to speak negatively about his rival's boxing ability.
"Jake Paul is a credible opponent," he said.
Paul's History
Jake Paul - who initially became famous on the television network - has primarily fought mixed martial artists or declining opponents since becoming pro.
He lost to British fighter Tommy Fury in last year.
Financial Success
Nevertheless, the inexperienced fighter is still one of boxing's biggest commercial attractions, regularly earning huge financial rewards.
Forecast and Belief
The 28 year old anticipated a stoppage in the fourth or fifth round and claimed he would prevent the highly-expected match between Joshua and Fury, which is apparently in the works for 2026.
"The next fight will be my match with Fury in the coming year," Jake Paul declared.
Physical Difference
As both boxers met for the usual stare-down, with their physical disparity on show, it drove home just how improbable this entire matchup is - and how astonishing it is that the fight is really going ahead.
