The British boxer will face Jake Paul in an eight-bout fight which will be streamed live on Netflix.
Briton Joshua said he will "dominate completely" Jake Paul and "break" his opponent as the two fighters came face-to-face to publicize next month's heavyweight fight.
Former two-time world title holder Anthony Joshua faces YouTuber-turned-boxer Jake Paul - in what is, by the numbers, a huge mismatch - at Miami's arena on December 19th.
Boxer's Attitude
"I will damage his features and damage his physique. My goal is to show I'm the better fighter," the British boxer, 35, declared.
"I will dominate him completely. That's a fighter's mentality.
"I'm going to seriously aim to cause him pain. That's my intention."
Respectful Exchange
Despite these statements, a relaxed Anthony Joshua and social media star Paul - typically famous for his showmanship - shared friendly words and maintained decorum with each other.
Jake Paul rather targeted ex Joshua opponent the Cameroonian fighter and described him as "ridiculous" after Ngannou turned down a bout proposal.
Taking Aim at Fury
Anthony Joshua, at the same time, took aim at UK opponent Tyson Fury - and declined a large bet 'Tyson Fury' says he will place on a Paul win.
"[Paul] outshines Fury - he showed up," Joshua said.
"I acknowledge that."
Legitimate Fighter
In spite of stating he plans to hurt Jake Paul, Joshua declined to speak negatively about his rival's boxing ability.
"Jake is a legitimate boxer," he stated.
Jake Paul's History
Jake Paul - who initially became famous on the Disney Channel - has primarily fought mixed martial artists or past-their-prime fighters since entering professional boxing.
He lost to Briton Fury in last year.
Financial Attraction
Still, the novice remains one of the sport's greatest commercial attractions, frequently receiving substantial earnings.
Prediction and Confidence
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 in the works for 2026.
"It's going to be myself against Tyson Fury in the coming year," Jake Paul stated.
Physical Difference
As the two fighters engaged in the customary confrontation, with their size difference clearly visible, it drove home just how surprising this whole event is - and how remarkable it is that the fight is really happening.
