The British boxer will face the American YouTuber in an eight-bout fight which will be streamed live on Netflix.
Briton Joshua said he will "stamp all over" Jake Paul and "break" the American as the two fighters met personally to promote next month's boxing match.
Ex two time unified boxing king Anthony Joshua faces YouTuber-turned-boxer Paul - in what is, theoretically, a huge mismatch - at Miami's Kaseya Center on December 19th.
"I'm going to injure his face and break his body up. My goal is to show my superiority," the British boxer, 35 years old, said.
"I'll stamp all over him. That's a fighter's mentality.
"I intend to seriously aim to hurt him. That's what I want to do."
Despite these statements, a composed Joshua and social media star Jake Paul - normally famous for his theatrics - exchanged pleasantries and kept it respectful with each other.
Jake Paul instead targeted ex Joshua rival the Cameroonian fighter and called him "not serious" after the Cameroonian turned down a fight offer.
Anthony Joshua, in the meantime, took aim at British rival Fury - and declined a £1m bet 'Tyson Fury' states he will put on a Paul victory.
"[Paul] outshines Fury - he's actually sitting here," Joshua said.
"I respect him for that."
Despite saying he intends to punish Paul, Joshua declined to talk badly about his rival's pugilistic talent.
"Jake Paul is a legitimate boxer," he said.
Paul - who initially became famous on the television network - has mainly fought mixed martial artists or faded names since turning professional.
He lost to Briton Tommy Fury in 2023.
Still, the inexperienced fighter is still one of boxing's greatest commercial attractions, frequently receiving massive financial rewards.
The 28-year-old forecast a KO victory in rounds four or five and stated he would stop the much-anticipated Fury-Joshua bout, which is allegedly being planned for 2026.
"The next fight will be my match with Fury next year," Jake Paul stated.
As Joshua and Paul engaged in the customary confrontation, with their height and weight contrast on show, it drove home just how unlikely this entire matchup is - and how astonishing it is that the match is truly going ahead.
