Anthony Joshua is set to fight the American YouTuber in an eight round match which will be shown in real-time on the streaming platform.
Briton Joshua said he will "stamp all over" Jake Paul and "overpower" his opponent as the combatants came face-to-face to promote next month's bout.
Ex twice world heavyweight champion Anthony Joshua battles YouTuber-turned-boxer Jake Paul - in what is, by the numbers, a mammoth mismatch - at Miami's venue on 19 December.
Boxer's Mentality
"I will damage his features and damage his physique. I'm here to prove I'm superior," Joshua, 35, stated.
"I will dominate him completely. That's how fighters think.
"I intend to genuinely try to injure him. That's what I want to do."
Civil Exchange
Despite these statements, a composed Joshua and internet personality Paul - usually recognized for his theatrics - were respectful and kept it respectful with each other.
Jake Paul rather criticized ex Joshua's rival Francis Ngannou and labeled him "not serious" after the Cameroonian declined a match opportunity.
Taking Aim at Fury
Joshua, meanwhile, criticized UK opponent Tyson Fury - and declined a large bet 'The Gypsy King' says he will place on a Paul victory.
"Jake Paul outshines Tyson Fury - he's actually sitting here," Joshua stated.
"I give him credit for that."
Legitimate Opponent
In spite of declaring he will punish Paul, Anthony Joshua refused to talk badly about his rival's fighting skills.
"Jake is a serious fighter," he remarked.
Jake Paul's History
Jake Paul - who first rose to fame on the Disney Channel - has primarily fought mixed martial artists or declining opponents since turning professional.
He lost to Briton Fury in last year.
Financial Success
Nevertheless, the inexperienced fighter continues to be one of the sport's greatest money-making draws, frequently receiving massive financial rewards.
Prediction and Confidence
The 28 year old predicted a KO victory in the fourth or fifth round and claimed he would prevent the much-anticipated Fury-Joshua bout, which is reportedly under discussion for two years from now.
"It will be myself against Tyson Fury next year," Jake Paul declared.
Physical Difference
As the two fighters met for the traditional face-off, with their size difference clearly visible, it highlighted just how surprising this whole event is - and how remarkable it is that the bout is actually going ahead.
