The British boxer will face Jake Paul in an eight round match which will be broadcast live on Netflix.
Briton Joshua said he will "overwhelm entirely" the American and "break" his opponent as the pair confronted each other to build hype for the upcoming bout.
Former two time unified heavyweight champion Anthony Joshua faces social media star turned fighter Paul - in what is, theoretically, a massive uneven pairing - at Miami's arena on 19 December.
Fighter's Attitude
"I'm going to damage his features and break his body up. My goal is to show I'm the better fighter," Joshua, 35, declared.
"I plan to overwhelm him. That's a fighter's mentality.
"I intend to genuinely try to hurt him. That's my intention."
Civil Exchange
In spite of those words, a relaxed Joshua and internet personality Paul - normally famous for his theatrics - shared friendly words and remained civil with each other.
Jake Paul rather attacked ex Joshua's rival the Cameroonian fighter and called him "a joke" after Ngannou rejected a bout proposal.
Targeting Tyson Fury
Joshua, meanwhile, targeted British rival Fury - and rejected a large bet 'The Gypsy King' claims he will make on a Paul win.
"Jake Paul is superior to Fury - he's present here," the boxer commented.
"I respect him for that."
Serious Opponent
In spite of saying he intends to punish Paul, Anthony Joshua chose not to comment unfavorably about his opponent's pugilistic talent.
"Jake Paul is a legitimate boxer," he stated.
Jake Paul's History
Paul - who first rose to fame on the Disney Channel - has mainly fought mixed martial artists or past-their-prime fighters since turning professional.
He was defeated by British fighter Fury in last year.
Financial Attraction
Still, the relative newcomer is still one of boxing's largest money-making draws, regularly earning substantial financial rewards.
Forecast and Belief
The 28-year-old predicted a stoppage in the fourth or fifth round and claimed he would derail the highly-expected Fury-Joshua bout, which is allegedly in the works for two years from now.
"It will be my match with Fury in the coming year," Jake Paul said.
Physical Disparity
As the two fighters participated in the customary face-off, with their physical disparity evident, it highlighted just how surprising this complete situation is - and how remarkable it is that the fight is actually happening.
