The British boxer is set to fight Jake Paul in an eight-round match which will be streamed in real-time on Netflix.
Briton Joshua declared he will "overwhelm entirely" Jake Paul and "break" the American as the combatants confronted each other to build hype for next month's bout.
Former two time unified boxing king Anthony Joshua meets social media star turned fighter Paul - in what is, theoretically, a huge uneven pairing - at Miami arena on December 19th.
"I will break his face and hurt his body. I aim to demonstrate I'm superior," the British boxer, 35, said.
"I will dominate him completely. That's how fighters think.
"I intend to seriously aim to cause him pain. That's my goal."
Despite such comments, a calm Joshua and internet personality Paul - usually known for his theatrics - exchanged pleasantries and remained civil with each other.
Jake Paul instead targeted ex Joshua opponent the Cameroonian fighter and labeled him "ridiculous" after Ngannou rejected a bout proposal.
Anthony Joshua, at the same time, criticized UK opponent Fury - and rejected a £1m bet 'Tyson Fury' states he will put on a victory for Paul.
"Jake Paul is better than Fury - he's present here," Joshua commented.
"I acknowledge that."
In spite of declaring he will punish Paul, Joshua chose not to speak negatively about his rival's fighting skills.
"Jake Paul is a legitimate boxer," he said.
Paul - who originally gained popularity on the television network - has mainly fought mixed martial artists or faded names since becoming pro.
He was defeated by British fighter Tommy Fury in 2023.
Nevertheless, the inexperienced fighter continues to be one of boxing's greatest commercial attractions, frequently receiving substantial financial rewards.
The 28 year old forecast a stoppage in round four or five and stated he would prevent the much-anticipated match between Joshua and Fury, which is allegedly in the works for two years from now.
"It's going to be myself against Tyson Fury next year," Paul said.
As the two fighters participated in the usual stare-down, with their size difference clearly visible, it emphasized just how improbable this whole event is - and how astonishing it is that the match is really going ahead.
