Anthony Joshua will face the American YouTuber in an eight round match which will be shown in real-time on the streaming platform.
British boxer Joshua stated he will "overwhelm entirely" Jake Paul and "defeat" his opponent as the pair met personally to promote the upcoming boxing match.
Former two-time unified heavyweight champion Joshua battles social media star turned fighter Paul - in what is, on paper, a mammoth mismatch - at Miami's arena on 19 December.
Fighter's Mentality
"I will damage his features and hurt his body. I aim to demonstrate I'm the better fighter," Joshua, 35, stated.
"I will dominate him completely. That's the boxer's mindset.
"I will seriously aim to hurt him. That's my goal."
Respectful Exchange
In spite of such comments, a relaxed Joshua and social media star Paul - usually recognized for his showmanship - exchanged pleasantries and remained civil with each other.
Jake Paul rather targeted former Joshua's rival Francis Ngannou and called him "a joke" after the Cameroonian turned down a fight offer.
Taking Aim at Tyson Fury
Joshua, at the same time, criticized UK opponent Tyson Fury - and rejected a £1m bet 'Tyson Fury' states he will put on a victory for Paul.
"Jake Paul is better than Fury - he showed up," Joshua stated.
"I respect him for that."
Serious Opponent
In spite of saying he intends to punish Paul, Joshua refused to speak negatively about his rival's fighting skills.
"Jake is a credible opponent," he stated.
Jake Paul's Background
Paul - who originally gained popularity on the Disney Channel - has primarily fought MMA fighters or faded names since becoming pro.
He was defeated by Briton Fury in last year.
Financial Success
Nevertheless, the novice continues to be one of the sport's largest financial successes, regularly earning massive paydays.
Prediction and Belief
The 28 year old forecast a stoppage in the fourth or fifth round and claimed he would stop the long-awaited match between Joshua and Fury, which is apparently under discussion for two years from now.
"It will be myself against Tyson Fury next year," Jake Paul said.
Size Difference
As the two fighters engaged in the traditional confrontation, with their size difference clearly visible, it drove home just how unlikely this entire matchup is - and how amazing it is that the fight is really going ahead.
