The British boxer is set to fight the American YouTuber in an eight-round contest which will be streamed in real-time on the streaming platform.
Briton Joshua declared he will "overwhelm entirely" the American and "break" his opponent as the two fighters met personally to publicize the upcoming heavyweight fight.
Former twice unified heavyweight champion Anthony Joshua meets social media star turned fighter Paul - in what is, by the numbers, a huge uneven pairing - at Miami's Kaseya Center on December 19th.
"I will injure his face and hurt his body. I'm here to prove I'm superior," Joshua, 35 years old, said.
"I'll stamp all over him. That's a fighter's mentality.
"I'm going to genuinely try to hurt him. That's my goal."
Despite such comments, a relaxed Joshua and internet personality Jake Paul - usually known for his dramatics - were respectful and maintained decorum with each other.
Jake Paul instead targeted ex Joshua opponent Francis Ngannou and called him "not serious" after the Cameroonian declined a bout proposal.
Anthony Joshua, meanwhile, targeted UK opponent Fury - and rejected a £1m bet 'The Gypsy King' claims he will make on a victory for Paul.
"Jake Paul outshines Tyson Fury - he's present here," the boxer said.
"I acknowledge that."
In spite of saying he intends to hurt Jake Paul, Joshua declined to comment unfavorably about his rival's boxing ability.
"Jake is a credible opponent," he stated.
Jake Paul - who originally gained popularity on the television network - has mostly fought mixed martial artists or past-their-prime fighters since becoming pro.
He lost to British fighter Fury in 2023.
Still, the relative newcomer is still one of the sport's largest commercial attractions, frequently receiving substantial paydays.
The 28 year old forecast a stoppage in the fourth or fifth round and stated he would derail the long-awaited match between Joshua and Fury, which is apparently being planned for two years from now.
"The next fight will be myself against Tyson Fury next year," Paul stated.
As both boxers participated in the usual confrontation, with their height and weight contrast clearly visible, it emphasized just how improbable this complete situation is - and how astonishing it is that the fight is actually going ahead.
