The British boxer is set to fight the American YouTuber in an eight-round contest which will be broadcast live on Netflix.
Briton Joshua stated he will "dominate completely" Jake Paul and "overpower" his opponent as the two fighters came face-to-face to publicize next month's heavyweight fight.
Former two-time world title holder Joshua meets YouTuber-turned-boxer Paul - in what is, by the numbers, a huge uneven pairing - at Miami's venue on December 19th.
"I will break his face and break his body up. I aim to demonstrate I'm the better fighter," Joshua, 35 years old, stated.
"I'll stamp all over him. That's the boxer's mindset.
"I intend to really want to cause him pain. That's my goal."
In spite of such comments, a composed Joshua and internet personality Paul - normally known for his showmanship - exchanged pleasantries and kept it respectful with each other.
Jake Paul instead attacked ex Joshua opponent the Cameroonian fighter and called him "ridiculous" after the Cameroonian rejected a bout proposal.
Joshua, meanwhile, targeted UK opponent Fury - and rejected a ÂŁ1m bet 'Tyson Fury' says he will place on a Paul win.
"[Paul] is better than Tyson Fury - he's actually sitting here," Joshua said.
"I acknowledge that."
In spite of declaring he will damage his opponent, Joshua declined to talk badly about his rival's boxing ability.
"Jake is a credible opponent," he stated.
Paul - who first rose to fame on the Disney Channel - has mainly boxed mixed martial artists or declining opponents since entering professional boxing.
He was defeated by British fighter Fury in last year.
Still, the novice remains one of boxing's biggest commercial attractions, frequently receiving massive financial rewards.
The 28-year-old predicted a knockout win in round four or five and asserted he would prevent the long-awaited Joshua–Fury fight, which is reportedly in the works for two years from now.
"The next fight will be my match with Fury in the coming year," Jake Paul stated.
As Joshua and Paul met for the traditional confrontation, with their size difference on show, it drove home just how surprising this entire matchup is - and how remarkable it is that the match is truly going ahead.
