The British boxer prepares to battle the American YouTuber in an eight-bout contest which will be streamed live on the streaming platform.
British boxer Joshua declared he will "stamp all over" Jake Paul and "overpower" his opponent as the combatants confronted each other to promote next month's bout.
Former twice unified boxing king Joshua faces social media star turned fighter Paul - in what is, on paper, a huge disparity - at Miami arena on December 19th.
"I'm going to injure his face and hurt his body. I aim to demonstrate I'm the better fighter," Joshua, 35, said.
"I will dominate him completely. That's the boxer's mindset.
"I'm going to really want to injure him. That's my goal."
In spite of these statements, a calm Anthony Joshua and internet personality Jake Paul - typically famous for his theatrics - exchanged pleasantries and kept it respectful with each other.
Paul rather attacked ex Joshua's opponent the Cameroonian fighter and labeled him "not serious" after the Cameroonian declined a fight offer.
Anthony Joshua, meanwhile, targeted British rival Tyson Fury - and declined a million-pound wager 'The Gypsy King' claims he will make on a victory for Paul.
"Jake Paul outshines Fury - he's actually sitting here," the boxer commented.
"I respect him for that."
Despite declaring he will punish Paul, Anthony Joshua chose not to comment unfavorably about his opponent's boxing ability.
"Jake is a serious fighter," he said.
Jake Paul - who initially became famous on the television network - has mostly fought mixed martial artists or declining opponents since turning professional.
He lost to Briton Tommy Fury in last year.
Still, the relative newcomer continues to be one of the sport's greatest money-making draws, consistently making huge financial rewards.
The 28-year-old anticipated a knockout win in the fourth or fifth round and claimed he would prevent the highly-expected Fury-Joshua bout, which is reportedly being planned for 2026.
"The next fight will be myself against Tyson Fury in the coming year," Jake Paul said.
As both boxers engaged in the traditional confrontation, with their physical disparity on show, it emphasized just how improbable this complete situation is - and how amazing it is that the bout is really proceeding.
