Anthony Joshua will face the American YouTuber in an eight-bout match which will be broadcast live on the streaming platform.
British boxer Joshua stated he will "overwhelm entirely" Jake Paul and "defeat" his opponent as the pair met personally to promote next month's bout.
Former two-time world title holder Joshua battles YouTuber-turned-boxer Paul - in what is, theoretically, a huge mismatch - at Miami's arena on 19 December.
Boxer's Attitude
"I will injure his face and break his body up. I aim to demonstrate I'm the better fighter," Joshua, 35, said.
"I plan to overwhelm him. That's how fighters think.
"I intend to really want to injure him. That's what I want to do."
Respectful Exchange
In spite of such comments, a composed Anthony Joshua and internet personality Jake Paul - typically recognized for his showmanship - shared friendly words and kept it respectful with each other.
Jake Paul instead criticized former Joshua rival the Cameroonian fighter and called him "ridiculous" after the Cameroonian declined a fight offer.
Targeting Fury
Anthony Joshua, meanwhile, targeted 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," Joshua said.
"I acknowledge that."
Serious Opponent
In spite of saying he intends to damage his opponent, Anthony Joshua refused to talk badly about his opponent's fighting skills.
"Jake Paul is a serious fighter," he said.
Paul's Background
Jake Paul - who initially became famous on the television network - has primarily boxed mixed martial artists or past-their-prime fighters since becoming pro.
He lost to British fighter Tommy Fury in last year.
Financial Success
However, the relative newcomer continues to be one of the sport's biggest financial successes, regularly earning substantial paydays.
Prediction and Belief
The 28-year-old predicted a stoppage in round four or five and stated he would stop the long-awaited Joshua–Fury fight, which is allegedly being planned for 2026.
"It's going to be myself against Tyson Fury next year," Paul said.
Physical Disparity
As the two fighters engaged in the traditional stare-down, with their physical disparity on show, it highlighted just how improbable this entire matchup is - and how astonishing it is that the match is really going ahead.
