The British boxer prepares to battle the American YouTuber in an eight round match which will be streamed in real-time on the streaming platform.
Briton Joshua declared he will "stamp all over" the American and "break" the American as the pair met personally to publicize the upcoming bout.
Former twice world title holder Joshua meets YouTuber-turned-boxer Jake Paul - in what is, by the numbers, a huge uneven pairing - at Miami's arena on December 19th.
Boxer's Mentality
"I plan to injure his face and damage his physique. I aim to demonstrate my superiority," Joshua, 35 years old, declared.
"I plan to overwhelm him. That's a fighter's mentality.
"I will really want to injure him. That's my intention."
Respectful Exchange
In spite of those words, a relaxed Anthony Joshua and social media star Paul - usually recognized for his dramatics - were respectful and kept it respectful with each other.
Paul instead criticized former Joshua's opponent Francis Ngannou and described him as "ridiculous" after the Cameroonian rejected a match opportunity.
Targeting Fury
Joshua, meanwhile, criticized UK rival Fury - and declined a million-pound wager 'Tyson Fury' says he will place on a victory for Paul.
"[Paul] outshines Tyson Fury - he showed up," the boxer stated.
"I give him credit for that."
Legitimate Fighter
Despite declaring he will punish Paul, Joshua refused to speak negatively about his rival's pugilistic talent.
"Jake Paul is a credible opponent," he stated.
Jake Paul's History
Paul - who originally gained popularity on the Disney Channel - has primarily boxed mixed martial artists or declining opponents since entering professional boxing.
He was defeated by Briton Fury in last year.
Financial Success
Still, the relative newcomer remains one of the sport's largest financial successes, regularly earning huge paydays.
Forecast and Belief
The 28 year old anticipated a knockout win in the fourth or fifth round and claimed he would derail the long-awaited match between Joshua and Fury, which is apparently being planned for two years from now.
"It will be myself against Tyson Fury next year," Jake Paul declared.
Physical Disparity
As Joshua and Paul met for the customary stare-down, with their height and weight contrast on show, it drove home just how unlikely this entire matchup is - and how amazing it is that the fight is really going ahead.
