The British boxer will face the American YouTuber in an eight-round contest which will be streamed live on Netflix.
Briton Joshua stated he will "overwhelm entirely" the American and "break" the American as the two fighters met personally to promote next month's boxing match.
Former two-time unified heavyweight champion Anthony Joshua battles YouTuber-turned-boxer Jake Paul - in what is, by the numbers, a massive uneven pairing - at Miami's arena on 19 December.
Fighter's Mindset
"I will break his face and damage his physique. I aim to demonstrate I'm superior," the British boxer, 35 years old, declared.
"I'll stamp all over him. That's how fighters think.
"I'm going to genuinely try to injure him. That's my goal."
Civil Interaction
Despite those words, a composed Anthony Joshua and internet personality Paul - usually recognized for his showmanship - were respectful and maintained decorum with each other.
Jake Paul rather targeted ex Joshua opponent Francis Ngannou and called him "a joke" after Ngannou declined a fight offer.
Targeting Tyson Fury
Anthony Joshua, at the same time, took aim at British opponent Fury - and declined a million-pound wager 'Tyson Fury' states he will put on a victory for Paul.
"Jake Paul is superior to Fury - he's present here," the boxer said.
"I give him credit for that."
Serious Fighter
In spite of saying he intends to damage his opponent, Anthony Joshua chose not to talk badly about his opponent's boxing ability.
"Jake is a credible opponent," he remarked.
Paul's Background
Jake Paul - who originally gained popularity on the Disney Channel - has mainly fought mixed martial artists or faded names since turning professional.
He was defeated by British fighter Tommy Fury in last year.
Commercial Success
Still, the novice continues to be one of the sport's greatest money-making draws, consistently making huge financial rewards.
Forecast and Belief
The 28-year-old anticipated a stoppage in rounds four or five and claimed he would prevent the much-anticipated match between Joshua and Fury, which is allegedly in the works for 2026.
"It will be myself against Tyson Fury in the coming year," Paul said.
Physical Difference
As Joshua and Paul participated in the usual stare-down, with their size difference on show, it emphasized just how unlikely this complete situation is - and how amazing it is that the bout is actually proceeding.
