Anthony Joshua will face the American YouTuber in an eight-round contest which will be streamed live on the streaming platform.
British boxer Joshua stated he will "overwhelm entirely" the American and "defeat" his opponent as the two fighters met personally to promote next month's bout.
Ex two-time unified title holder Anthony Joshua meets social media star turned fighter Paul - in what is, by the numbers, a massive disparity - at Miami Kaseya Center on December 19th.
"I'm going to break his face and hurt his body. I'm here to prove I'm superior," Joshua, 35 years old, stated.
"I'll stamp all over him. That's how fighters think.
"I will seriously aim to cause him pain. That's my intention."
Despite those words, a relaxed Joshua and internet personality Jake Paul - usually famous for his theatrics - exchanged pleasantries and kept it respectful with each other.
Jake Paul rather attacked former Joshua's opponent Francis Ngannou and described him as "a joke" after the Cameroonian declined a bout proposal.
Anthony Joshua, meanwhile, targeted UK opponent Tyson Fury - and declined a large bet 'Tyson Fury' says he will place on a Paul victory.
"Jake Paul outshines Tyson Fury - he showed up," Joshua said.
"I acknowledge that."
Despite stating he plans to punish Paul, Joshua declined to talk badly about his rival's boxing ability.
"Jake is a serious fighter," he stated.
Paul - who initially became famous on the Disney Channel - has mainly fought MMA fighters or declining opponents since turning professional.
He lost to Briton Tommy Fury in last year.
However, the novice remains one of the sport's greatest money-making draws, frequently receiving huge earnings.
The 28 year old anticipated a knockout win in rounds four or five and stated he would derail the long-awaited match between Joshua and Fury, which is reportedly being planned for 2026.
"The next fight will be myself against Tyson Fury next year," Jake Paul declared.
As Joshua and Paul participated in the usual face-off, with their size difference on show, it highlighted just how unlikely this whole event is - and how astonishing it is that the bout is actually proceeding.
