The British boxer will face the American YouTuber in an eight-round contest which will be broadcast in real-time on the streaming platform.
British boxer Joshua stated he will "dominate completely" the American and "defeat" his opponent as the two fighters confronted each other to publicize the upcoming heavyweight fight.
Former twice unified boxing king Joshua battles social media star turned fighter Paul - in what is, by the numbers, a huge disparity - at Miami's arena on December 19th.
Boxer's Mentality
"I plan to injure his face and break his body up. I aim to demonstrate I'm superior," the British boxer, 35, said.
"I plan to overwhelm him. That's how fighters think.
"I intend to seriously aim to hurt him. That's what I want to do."
Respectful Interaction
In spite of such comments, a relaxed Joshua and internet personality Paul - typically known for his dramatics - exchanged pleasantries and maintained decorum with each other.
Paul rather attacked ex Joshua rival the Cameroonian fighter and described him as "ridiculous" after the Cameroonian rejected a match opportunity.
Taking Aim at Tyson Fury
Anthony Joshua, meanwhile, criticized British rival Fury - and declined a £1m bet 'Tyson Fury' states he will put on a victory for Paul.
"Jake Paul outshines Tyson Fury - he's present here," Joshua said.
"I give him credit for that."
Serious Opponent
Despite stating he plans to damage his opponent, Anthony Joshua refused to speak negatively about his opponent's pugilistic talent.
"Jake Paul is a serious fighter," he said.
Paul's Background
Jake Paul - who originally gained popularity on the television network - has primarily fought mixed martial artists or past-their-prime fighters since entering professional boxing.
He lost to Briton Fury in last year.
Commercial Attraction
Still, the inexperienced fighter is still one of boxing's biggest commercial attractions, frequently receiving massive financial rewards.
Forecast and Belief
The 28-year-old predicted a stoppage in rounds four or five and asserted he would prevent the highly-expected Joshua–Fury fight, which is allegedly in the works for two years from now.
"It's going to be me versus Tyson Fury next year," Paul declared.
Size Difference
As Joshua and Paul met for the customary confrontation, with their physical disparity clearly visible, it emphasized just how improbable this whole event is - and how astonishing it is that the fight is actually happening.
