Anthony Joshua is set to fight Jake Paul in an eight-round fight which will be shown live on Netflix.
Briton Joshua said he will "dominate completely" Jake Paul and "break" the American as the pair came face-to-face to promote next month's bout.
Ex twice world title holder Anthony Joshua battles social media star turned fighter Paul - in what is, theoretically, a mammoth mismatch - at Miami arena on 19 December.
Fighter's Mindset
"I'm going to damage his features and break his body up. I'm here to prove I'm superior," the British boxer, 35 years old, said.
"I'll stamp all over him. That's a fighter's mentality.
"I'm going to seriously aim to hurt him. That's what I want to do."
Civil Exchange
Despite such comments, a composed Joshua and internet personality Jake Paul - usually known for his showmanship - shared friendly words and maintained decorum with each other.
Jake Paul instead attacked ex Joshua rival Francis Ngannou and called him "a joke" after the Cameroonian turned down a fight offer.
Taking Aim at Tyson Fury
Joshua, meanwhile, took aim at UK opponent Fury - and declined a large bet 'Tyson Fury' claims he will make on a Paul victory.
"[Paul] outshines Tyson Fury - he's actually sitting here," the boxer stated.
"I respect him for that."
Legitimate Opponent
Despite stating he plans to hurt Jake Paul, Anthony Joshua refused to comment unfavorably about his opponent's boxing ability.
"Jake is a credible opponent," he remarked.
Jake Paul's Background
Paul - who originally gained popularity on the Disney Channel - has mostly boxed MMA fighters or declining opponents since turning professional.
He was defeated by British fighter Fury in last year.
Financial Attraction
Nevertheless, the relative newcomer is still one of the sport's biggest financial successes, regularly earning huge financial rewards.
Forecast and Belief
The 28-year-old anticipated a knockout win in the fourth or fifth round and stated he would derail the long-awaited match between Joshua and Fury, which is allegedly under discussion for two years from now.
"It's going to be myself against Tyson Fury next year," Paul stated.
Physical Difference
As both boxers engaged in the usual stare-down, with their size difference evident, it drove home just how unlikely this entire matchup is - and how amazing it is that the fight is actually going ahead.
