Anthony Joshua will face Jake Paul in an eight round contest which will be streamed in real-time on the streaming platform.
Briton Joshua said he will "dominate completely" Jake Paul and "overpower" his opponent as the two fighters came face-to-face to build hype for next month's bout.
Former two-time unified title holder Anthony Joshua battles YouTuber-turned-boxer Paul - in what is, by the numbers, a mammoth disparity - at Miami Kaseya Center on 19 December.
Fighter's Mentality
"I'm going to damage his features and break his body up. I'm here to prove I'm superior," Joshua, 35 years old, stated.
"I will dominate him completely. That's how fighters think.
"I will genuinely try to cause him pain. That's my intention."
Respectful Exchange
In spite of these statements, a calm Joshua and internet personality Jake Paul - normally known for his dramatics - were respectful and maintained decorum with each other.
Paul instead attacked ex Joshua's rival Francis Ngannou and labeled 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 £1m bet 'Tyson Fury' says he will place on a Paul victory.
"Jake Paul is superior to Fury - he's actually sitting here," Joshua said.
"I acknowledge that."
Serious Fighter
Despite stating he plans to hurt Jake Paul, Joshua refused to comment unfavorably about his opponent's fighting skills.
"Jake is a legitimate boxer," he said.
Paul's Background
Paul - who originally gained popularity on the Disney Channel - has mostly boxed MMA fighters or past-their-prime fighters since entering professional boxing.
He lost to Briton Fury in last year.
Commercial Attraction
Still, the inexperienced fighter remains one of boxing's biggest money-making draws, frequently receiving massive financial rewards.
Forecast and Belief
The 28 year old forecast a knockout win in the fourth or fifth round and asserted he would prevent the long-awaited match between Joshua and Fury, which is reportedly under discussion for 2026.
"It will be my match with Fury in the coming year," Paul said.
Size Disparity
As the two fighters participated in the usual face-off, with their size difference clearly visible, it highlighted just how unlikely this whole event is - and how amazing it is that the fight is really proceeding.
