The British boxer is set to fight the American YouTuber in an eight-bout match which will be shown live on the streaming platform.
Briton Joshua said he will "overwhelm entirely" the American and "defeat" the American as the two fighters met personally to publicize next month's heavyweight fight.
Ex two-time unified heavyweight champion Anthony Joshua meets social media star turned fighter Paul - in what is, theoretically, a mammoth uneven pairing - at Miami arena on 19 December.
Fighter's Mentality
"I will injure his face and damage his physique. My goal is to show I'm superior," Joshua, 35 years old, said.
"I'll stamp all over him. That's the boxer's mindset.
"I'm going to seriously aim to injure him. That's my intention."
Civil Exchange
In spite of those words, a relaxed Joshua and internet personality Paul - usually recognized for his dramatics - exchanged pleasantries and maintained decorum with each other.
Paul rather criticized former Joshua rival the Cameroonian fighter and described him as "ridiculous" after the Cameroonian turned down a bout proposal.
Targeting Fury
Joshua, in the meantime, took aim at British rival Tyson Fury - and rejected a million-pound wager 'The Gypsy King' claims he will make on a Paul win.
"[Paul] is better than Tyson Fury - he's actually sitting here," Joshua said.
"I give him credit for that."
Legitimate Fighter
Despite declaring he will hurt Jake Paul, Joshua chose not to talk badly about his opponent's boxing ability.
"Jake is a serious fighter," he stated.
Jake Paul's Background
Paul - who first rose to fame on the television network - has mainly fought mixed martial artists or declining opponents since turning professional.
He was defeated by British fighter Fury in last year.
Financial Attraction
Nevertheless, the relative newcomer is still one of the sport's largest commercial attractions, regularly earning massive financial rewards.
Prediction and Belief
The 28-year-old anticipated a KO victory in round four or five and claimed he would derail the long-awaited Fury-Joshua bout, which is allegedly in the works for two years from now.
"It will be me versus Tyson Fury next year," Jake Paul declared.
Physical Difference
As the two fighters engaged in the usual face-off, with their height and weight contrast clearly visible, it emphasized just how improbable this whole event is - and how amazing it is that the fight is really going ahead.
