Anthony Joshua will face Jake Paul in an eight-bout match which will be streamed live on the streaming platform.
Briton Joshua said he will "overwhelm entirely" Jake Paul and "break" the American as the pair came face-to-face to publicize next month's bout.
Ex two time world boxing king Anthony Joshua meets YouTuber-turned-boxer Jake Paul - in what is, on paper, a massive uneven pairing - at Miami venue on 19 December.
"I will damage his features and break his body up. I aim to demonstrate I'm the better fighter," Joshua, 35, declared.
"I will dominate him completely. That's the boxer's mindset.
"I intend to genuinely try to injure him. That's what I want to do."
In spite of those words, a composed Joshua and social media star Jake Paul - usually known for his dramatics - shared friendly words and kept it respectful with each other.
Paul rather targeted ex Joshua opponent the Cameroonian fighter and called him "a joke" after the Cameroonian declined a fight offer.
Joshua, in the meantime, targeted British rival Fury - and rejected a £1m bet 'The Gypsy King' says he will place on a victory for Paul.
"[Paul] outshines Tyson Fury - he showed up," the boxer said.
"I respect him for that."
Despite stating he plans to hurt Jake Paul, Anthony Joshua chose not to talk badly about his opponent's pugilistic talent.
"Jake is a legitimate boxer," he said.
Jake Paul - who originally gained popularity on the Disney Channel - has primarily boxed mixed martial artists or declining opponents since entering professional boxing.
He was defeated by Briton Fury in last year.
Nevertheless, the inexperienced fighter is still one of the sport's largest money-making draws, regularly earning huge financial rewards.
The 28-year-old anticipated a knockout win in round four or five and claimed he would prevent the highly-expected Fury-Joshua bout, which is allegedly under discussion for 2026.
"The next fight will be me versus Tyson Fury next year," Paul said.
As the two fighters met for the traditional confrontation, with their physical disparity evident, it drove home just how improbable this whole event is - and how amazing it is that the bout is truly happening.
