The British boxer prepares to battle the American YouTuber in an eight-bout match which will be shown in real-time on the streaming platform.
Briton Joshua said he will "stamp all over" the American and "overpower" his opponent as the two fighters came face-to-face to promote the upcoming heavyweight fight.
Former two-time world heavyweight champion Joshua battles social media star turned fighter Paul - in what is, theoretically, a massive uneven pairing - at Miami venue on 19 December.
Fighter's Attitude
"I will injure his face and break his body up. I'm here to prove my superiority," Joshua, 35 years old, said.
"I plan to overwhelm him. That's the boxer's mindset.
"I'm going to genuinely try to injure him. That's my intention."
Respectful Exchange
In spite of such comments, a relaxed Joshua and social media star Paul - usually known for his theatrics - shared friendly words and maintained decorum with each other.
Paul rather attacked former Joshua's rival Francis Ngannou and labeled him "not serious" after Ngannou declined a match opportunity.
Taking Aim at Fury
Joshua, in the meantime, criticized British rival Fury - and declined a large bet 'The Gypsy King' states he will put on a Paul win.
"[Paul] outshines Fury - he showed up," Joshua commented.
"I respect him for that."
Legitimate Fighter
In spite of saying he intends to hurt Jake Paul, Joshua chose not to speak negatively about his rival's fighting skills.
"Jake Paul is a serious fighter," he said.
Jake Paul's History
Paul - who initially became famous on the Disney Channel - has mainly boxed mixed martial artists or past-their-prime fighters since entering professional boxing.
He lost to British fighter Fury in last year.
Financial Success
Still, the novice remains one of boxing's biggest financial successes, frequently receiving substantial paydays.
Forecast and Belief
The 28-year-old predicted a stoppage in the fourth or fifth round and stated he would prevent the long-awaited Fury-Joshua bout, which is allegedly in the works for two years from now.
"The next fight will be my match with Fury next year," Jake Paul said.
Physical Difference
As both boxers engaged in the usual stare-down, with their size difference clearly visible, it emphasized just how unlikely this whole event is - and how astonishing it is that the bout is truly proceeding.
