The British boxer prepares to battle the American YouTuber in an eight-bout match which will be broadcast live on the streaming platform.
Briton Joshua said he will "overwhelm entirely" the American and "break" his opponent as the combatants met personally to publicize the upcoming heavyweight fight.
Ex twice unified boxing king Joshua faces social media star turned fighter Jake Paul - in what is, by the numbers, a mammoth mismatch - at Miami Kaseya Center on 19 December.
Boxer's Mentality
"I plan to damage his features and damage his physique. I aim to demonstrate my superiority," Joshua, 35, said.
"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."
Respectful Exchange
Despite such comments, a calm Anthony Joshua and internet personality Jake Paul - typically recognized for his showmanship - exchanged pleasantries and remained civil with each other.
Jake Paul rather criticized former Joshua's rival the Cameroonian fighter and labeled him "a joke" after the Cameroonian turned down a fight offer.
Taking Aim at Tyson Fury
Anthony Joshua, at the same time, targeted UK opponent Fury - and rejected a £1m bet 'The Gypsy King' claims he will make on a Paul victory.
"Jake Paul outshines Tyson Fury - he showed up," the boxer stated.
"I respect him for that."
Legitimate Fighter
In spite of declaring he will punish Paul, Anthony Joshua refused to talk badly about his rival's pugilistic talent.
"Jake Paul is a legitimate boxer," he said.
Paul's History
Paul - who first rose to fame on the Disney Channel - has mainly boxed mixed martial artists or faded names since entering professional boxing.
He was defeated by Briton Tommy Fury in last year.
Commercial Attraction
Nevertheless, the novice is still one of the sport's biggest commercial attractions, frequently receiving substantial paydays.
Prediction and Belief
The 28-year-old forecast a stoppage in rounds four or five and claimed he would prevent the highly-expected Fury-Joshua bout, which is reportedly being planned for two years from now.
"It will be me versus Tyson Fury in the coming year," Jake Paul declared.
Size Difference
As the two fighters participated in the customary confrontation, with their height and weight contrast clearly visible, it drove home just how unlikely this entire matchup is - and how remarkable it is that the match is really going ahead.
