The British boxer will face Jake Paul in an eight-bout contest which will be streamed live on the streaming platform.
Briton Anthony Joshua declared he will "dominate completely" the American and "defeat" his opponent as the pair came face-to-face to build hype for the upcoming bout.
Former two-time unified boxing king Anthony Joshua battles YouTuber-turned-boxer Jake Paul - in what is, on paper, a mammoth mismatch - at Miami's Kaseya Center on 19 December.
Fighter's Mindset
"I plan to damage his features and damage his physique. I'm here to prove my superiority," the British boxer, 35, stated.
"I will dominate him completely. That's how fighters think.
"I'm going to seriously aim to injure him. That's my intention."
Civil Interaction
Despite such comments, a relaxed Joshua and social media star Paul - typically recognized for his showmanship - exchanged pleasantries and remained civil with each other.
Paul rather targeted former Joshua's opponent Francis Ngannou and called him "a joke" after the Cameroonian turned down a match opportunity.
Taking Aim at Tyson Fury
Anthony Joshua, meanwhile, took aim at British rival Fury - and rejected a large bet 'The Gypsy King' says he will place on a Paul victory.
"Jake Paul is better than Tyson Fury - he's present here," the boxer commented.
"I acknowledge that."
Legitimate Fighter
Despite saying he intends to punish Paul, Anthony Joshua declined to talk badly about his rival's fighting skills.
"Jake is a serious fighter," he remarked.
Jake Paul's Background
Jake Paul - who initially became famous on the television network - has mainly fought mixed martial artists or past-their-prime fighters since becoming pro.
He lost to Briton Tommy Fury in last year.
Financial Success
Nevertheless, the novice is still one of boxing's largest money-making draws, regularly earning substantial earnings.
Prediction and Confidence
The 28-year-old forecast a knockout win in the fourth or fifth round and asserted he would prevent the long-awaited Joshua–Fury fight, which is apparently in the works for two years from now.
"It will be me versus Tyson Fury next year," Jake Paul declared.
Physical Disparity
As the two fighters met for the customary face-off, with their physical disparity evident, it highlighted just how unlikely this entire matchup is - and how remarkable it is that the fight is actually happening.
