The British boxer prepares to battle Jake Paul in an eight-round fight which will be shown live on Netflix.
Briton Joshua declared he will "dominate completely" the American and "overpower" the American as the two fighters met personally to promote next month's heavyweight fight.
Ex two-time unified heavyweight champion Anthony Joshua battles YouTuber-turned-boxer Paul - in what is, theoretically, a massive disparity - at Miami's venue on 19 December.
Boxer's Attitude
"I will break his face and hurt his body. I aim to demonstrate I'm the better fighter," the British boxer, 35, said.
"I'll stamp all over him. That's the boxer's mindset.
"I'm going to really want to hurt him. That's my goal."
Civil Interaction
In spite of such comments, a composed Joshua and social media star Jake Paul - usually recognized for his theatrics - were respectful and remained civil with each other.
Jake Paul rather targeted former Joshua rival Francis Ngannou and described him as "ridiculous" after Ngannou turned down a match opportunity.
Taking Aim at Tyson Fury
Joshua, at the same time, took aim at British opponent Tyson Fury - and declined a million-pound wager 'Tyson Fury' says he will place on a Paul victory.
"[Paul] outshines Fury - he's actually sitting here," Joshua commented.
"I give him credit for that."
Serious Opponent
Despite declaring he will hurt Jake Paul, Joshua refused to speak negatively about his rival's fighting skills.
"Jake Paul is a serious fighter," he remarked.
Jake Paul's History
Jake Paul - who initially became famous on the Disney Channel - has mostly fought mixed martial artists or faded names since turning professional.
He lost to Briton Tommy Fury in last year.
Commercial Success
Still, the relative newcomer remains one of the sport's biggest money-making draws, frequently receiving massive paydays.
Forecast and Belief
The 28 year old forecast a knockout win in the fourth or fifth round and claimed he would derail the long-awaited Fury-Joshua bout, which is apparently being planned for two years from now.
"It will be myself against Tyson Fury in the coming year," Jake Paul stated.
Physical Disparity
As Joshua and Paul engaged in the usual stare-down, with their size difference clearly visible, it emphasized just how improbable this complete situation is - and how astonishing it is that the bout is truly proceeding.
