Anthony Joshua will face the American YouTuber in an eight-bout match which will be shown in real-time on the streaming platform.
British boxer Joshua said he will "stamp all over" Jake Paul and "defeat" his opponent as the combatants met personally to publicize next month's bout.
Former two-time unified title holder Joshua battles YouTuber-turned-boxer Paul - in what is, on paper, a mammoth mismatch - at Miami's Kaseya Center on 19 December.
Boxer's Attitude
"I will injure his face and damage his physique. My goal is to show I'm the better fighter," the British boxer, 35 years old, stated.
"I'll stamp all over him. That's the boxer's mindset.
"I'm going to really want to cause him pain. That's my intention."
Respectful Interaction
In spite of those words, a calm Joshua and internet personality Paul - usually recognized for his showmanship - were respectful and maintained decorum with each other.
Jake Paul rather attacked ex Joshua opponent the Cameroonian fighter and described him as "not serious" after Ngannou turned down a fight offer.
Taking Aim at Tyson Fury
Joshua, at the same time, criticized British opponent Fury - and declined a £1m bet 'Tyson Fury' says he will place on a Paul victory.
"[Paul] is superior to Fury - he's present here," the boxer commented.
"I give him credit for that."
Serious Fighter
Despite stating he plans to damage his opponent, Anthony Joshua refused to comment unfavorably about his opponent's fighting skills.
"Jake Paul is a legitimate boxer," he remarked.
Paul's Background
Paul - who initially became famous on the television network - has primarily boxed mixed martial artists or declining opponents since entering professional boxing.
He was defeated by Briton Fury in last year.
Financial Success
However, the relative newcomer continues to be one of the sport's largest commercial attractions, frequently receiving huge paydays.
Forecast and Confidence
The 28-year-old forecast a stoppage in round four or five and asserted he would derail the highly-expected match between Joshua and Fury, which is apparently under discussion for two years from now.
"It's going to be myself against Tyson Fury in the coming year," Paul said.
Size Disparity
As both boxers engaged in the usual stare-down, with their physical disparity clearly visible, it emphasized just how improbable this complete situation is - and how remarkable it is that the bout is really proceeding.
