The British boxer will face the American YouTuber in an eight-round fight which will be streamed live on Netflix.
Briton Joshua declared he will "overwhelm entirely" the American and "break" the American as the pair came face-to-face to build hype for the upcoming bout.
Ex two-time unified title holder Anthony Joshua meets YouTuber-turned-boxer Jake Paul - in what is, by the numbers, a mammoth mismatch - at Miami's Kaseya Center on 19 December.
"I plan to damage his features and hurt his body. My goal is to show my superiority," the British boxer, 35 years old, said.
"I'll stamp all over him. That's the boxer's mindset.
"I'm going to genuinely try to cause him pain. That's my intention."
Despite these statements, a relaxed Joshua and internet personality Jake Paul - usually recognized for his dramatics - exchanged pleasantries and remained civil with each other.
Jake Paul rather criticized former Joshua opponent Francis Ngannou and labeled him "not serious" after the Cameroonian turned down a fight offer.
Anthony Joshua, at the same time, targeted UK rival Tyson Fury - and refused a large bet 'Tyson Fury' claims he will make on a victory for Paul.
"[Paul] is better than Fury - he showed up," the boxer said.
"I give him credit for that."
Despite saying he intends to punish Paul, Anthony Joshua declined to comment unfavorably about his rival's pugilistic talent.
"Jake Paul is a credible opponent," he stated.
Jake Paul - who initially became famous on the Disney Channel - has mainly boxed MMA fighters or past-their-prime fighters since turning professional.
He was defeated by British fighter Fury in last year.
Still, the novice remains one of the sport's greatest money-making draws, consistently making huge earnings.
The 28-year-old anticipated a KO victory in the fourth or fifth round and claimed he would prevent the long-awaited match between Joshua and Fury, which is allegedly in the works for 2026.
"The next fight will be my match with Fury in the coming year," Paul stated.
As the two fighters participated in the usual face-off, with their physical disparity on show, it emphasized just how unlikely this complete situation is - and how remarkable it is that the fight is truly proceeding.
