Anthony Joshua is set to fight the American YouTuber in an eight-round fight which will be broadcast in real-time on Netflix.
Briton Joshua said he will "stamp all over" Jake Paul and "break" the American as the two fighters confronted each other to build hype for the upcoming boxing match.
Former two-time world title holder Joshua meets social media star turned fighter Jake Paul - in what is, by the numbers, a mammoth disparity - at Miami's arena on 19 December.
"I will injure his face and damage his physique. My goal is to show I'm the better fighter," the British boxer, 35 years old, said.
"I'll stamp all over him. That's how fighters think.
"I'm going to really want to injure him. That's my intention."
In spite of these statements, a composed Anthony Joshua and social media star Jake Paul - typically recognized for his theatrics - shared friendly words and kept it respectful with each other.
Jake Paul instead attacked former Joshua's opponent the Cameroonian fighter and labeled him "not serious" after Ngannou declined a match opportunity.
Joshua, in the meantime, took aim at British rival Tyson Fury - and refused a million-pound wager 'Tyson Fury' states he will put on a Paul win.
"[Paul] is better than Fury - he's present here," Joshua stated.
"I give him credit for that."
In spite of stating he plans to punish Paul, Joshua chose not to comment unfavorably about his rival's fighting skills.
"Jake is a serious fighter," he remarked.
Paul - who originally gained popularity on the Disney Channel - has primarily fought mixed martial artists or declining opponents since entering professional boxing.
He was defeated by Briton Fury in last year.
Still, the inexperienced fighter remains one of the sport's greatest commercial attractions, consistently making massive paydays.
The 28-year-old anticipated a stoppage in rounds four or five and stated he would stop the highly-expected Fury-Joshua bout, which is reportedly under discussion for two years from now.
"It will be me versus Tyson Fury in the coming year," Paul said.
As the two fighters engaged in the traditional stare-down, with their height and weight contrast on show, it highlighted just how improbable this whole event is - and how amazing it is that the bout is really proceeding.
