The British boxer will face Jake Paul in an eight-bout match which will be shown live on the streaming platform.
British boxer Joshua said he will "stamp all over" the American and "defeat" his opponent as the combatants met personally to build hype for the upcoming boxing match.
Former twice world boxing king Anthony Joshua meets social media star turned fighter Paul - in what is, by the numbers, a huge mismatch - at Miami's venue on 19 December.
Boxer's Mindset
"I will damage his features and break his body up. I'm here to prove I'm superior," Joshua, 35 years old, said.
"I plan to overwhelm him. That's the boxer's mindset.
"I'm going to seriously aim to cause him pain. That's my intention."
Respectful Exchange
In spite of those words, a relaxed Anthony Joshua and internet personality Jake Paul - normally recognized for his theatrics - exchanged pleasantries and maintained decorum with each other.
Paul rather attacked ex Joshua rival Francis Ngannou and called him "ridiculous" after the Cameroonian declined a fight offer.
Taking Aim at Fury
Joshua, in the meantime, took aim at British rival Fury - and refused a large bet 'Tyson Fury' says he will place on a Paul win.
"Jake Paul outshines Fury - he's actually sitting here," the boxer commented.
"I acknowledge that."
Legitimate Fighter
Despite declaring he will punish Paul, Anthony Joshua chose not to comment unfavorably about his opponent's boxing ability.
"Jake Paul is a serious fighter," he stated.
Jake Paul's History
Jake Paul - who initially became famous on the Disney Channel - has primarily fought MMA fighters or declining opponents since entering professional boxing.
He was defeated by British fighter Tommy Fury in last year.
Financial Success
Still, the novice continues to be one of the sport's largest commercial attractions, consistently making massive paydays.
Forecast and Confidence
The 28 year old anticipated a stoppage in rounds four or five and claimed he would derail the much-anticipated match between Joshua and Fury, which is apparently in the works for 2026.
"It's going to be myself against Tyson Fury in the coming year," Jake Paul said.
Size Difference
As Joshua and Paul met for the traditional face-off, with their size difference evident, it emphasized just how surprising this complete situation is - and how astonishing it is that the fight is really proceeding.
