The British boxer is set to fight Jake Paul in an eight-bout contest which will be streamed in real-time on Netflix.
British boxer Joshua said he will "dominate completely" the American and "defeat" his opponent as the pair met personally to promote next month's boxing match.
Ex two time unified title holder Joshua faces YouTuber-turned-boxer Paul - in what is, theoretically, a huge mismatch - at Miami venue on 19 December.
Boxer's Attitude
"I will break his face and damage his physique. I aim to demonstrate I'm the better fighter," Joshua, 35, said.
"I'll stamp all over him. That's a fighter's mentality.
"I will really want to cause him pain. That's my intention."
Respectful Exchange
In spite of those words, a relaxed Joshua and social media star Paul - normally famous for his showmanship - shared friendly words and remained civil with each other.
Paul rather attacked ex Joshua opponent Francis Ngannou and described him as "not serious" after Ngannou rejected a fight offer.
Targeting Tyson Fury
Anthony Joshua, at the same time, criticized UK opponent Tyson Fury - and rejected a million-pound wager 'The Gypsy King' says he will place on a Paul victory.
"[Paul] is superior to Fury - he's present here," the boxer said.
"I give him credit for that."
Legitimate Opponent
In spite of saying he intends to damage his opponent, Joshua declined to comment unfavorably about his opponent's boxing ability.
"Jake Paul is a legitimate boxer," he stated.
Jake Paul's Background
Paul - who initially became famous on the Disney Channel - has mostly fought mixed martial artists or declining opponents since entering professional boxing.
He was defeated by Briton Tommy Fury in last year.
Commercial Success
Nevertheless, the inexperienced fighter is still one of boxing's largest commercial attractions, frequently receiving massive paydays.
Forecast and Belief
The 28 year old predicted a knockout win in rounds four or five and claimed he would stop the highly-expected match between Joshua and Fury, which is allegedly under discussion for two years from now.
"It will be my match with Fury next year," Jake Paul said.
Physical Disparity
As the two fighters participated in the usual face-off, with their physical disparity evident, it drove home just how surprising this complete situation is - and how astonishing it is that the fight is actually proceeding.
