The British boxer will face the American YouTuber in an eight round fight which will be shown live on Netflix.
Briton Joshua stated he will "dominate completely" the American and "overpower" the American as the pair met personally to promote next month's boxing match.
Ex two time unified heavyweight champion Anthony Joshua meets social media star turned fighter Paul - in what is, theoretically, a huge mismatch - at Miami Kaseya Center on 19 December.
Boxer's Mentality
"I will break his face and break his body up. I aim to demonstrate I'm the better fighter," the British boxer, 35, said.
"I will dominate him completely. That's a fighter's mentality.
"I will genuinely try to cause him pain. That's my intention."
Civil Exchange
Despite such comments, a relaxed Anthony Joshua and social media star Jake Paul - typically known for his showmanship - shared friendly words and remained civil with each other.
Paul instead attacked ex Joshua opponent Francis Ngannou and described him as "not serious" after Ngannou turned down a bout proposal.
Targeting Tyson Fury
Joshua, meanwhile, targeted British opponent Tyson Fury - and declined a large bet 'The Gypsy King' says he will place on a Paul victory.
"Jake Paul is better than Tyson Fury - he's present here," Joshua commented.
"I acknowledge that."
Legitimate Fighter
In spite of declaring he will damage his opponent, Joshua refused to comment unfavorably about his rival's boxing ability.
"Jake Paul is a legitimate boxer," he said.
Jake Paul's Background
Jake Paul - who first rose to fame on the Disney Channel - has mainly fought mixed martial artists or faded names since becoming pro.
He lost to Briton Fury in 2023.
Financial Success
Still, the relative newcomer is still one of the sport's greatest financial successes, consistently making substantial financial rewards.
Forecast and Belief
The 28-year-old anticipated a KO victory in the fourth or fifth round and claimed he would stop the much-anticipated match between Joshua and Fury, which is reportedly in the works for two years from now.
"It will be myself against Tyson Fury next year," Paul stated.
Size Difference
As the two fighters participated in the traditional confrontation, with their size difference on show, it emphasized just how unlikely this whole event is - and how amazing it is that the fight is truly proceeding.
