Anthony Joshua is set to fight the American YouTuber in an eight-round fight which will be shown live on Netflix.
Briton Joshua declared he will "dominate completely" the American and "overpower" his opponent as the combatants confronted each other to publicize the upcoming boxing match.
Former two-time unified heavyweight champion Joshua meets social media star turned fighter Jake Paul - in what is, theoretically, a massive disparity - at Miami's Kaseya Center on 19 December.
Boxer's Attitude
"I will break his face and hurt his body. I'm here to prove I'm the better fighter," Joshua, 35, stated.
"I plan to overwhelm him. That's a fighter's mentality.
"I will seriously aim to injure him. That's what I want to do."
Civil Interaction
Despite those words, a relaxed Anthony Joshua and social media star Jake Paul - normally famous for his dramatics - shared friendly words and maintained decorum with each other.
Jake Paul rather targeted ex Joshua's rival Francis Ngannou and labeled him "not serious" after Ngannou rejected a fight offer.
Taking Aim at Fury
Anthony Joshua, in the meantime, took aim at UK rival Tyson Fury - and refused a million-pound wager 'The Gypsy King' claims he will make on a victory for Paul.
"Jake Paul is superior to Fury - he's present here," the boxer said.
"I respect him for that."
Legitimate Opponent
Despite saying he intends to punish Paul, Anthony Joshua chose not to talk badly about his opponent's pugilistic talent.
"Jake is a legitimate boxer," he said.
Jake Paul's Background
Jake Paul - who first rose to fame on the television network - has mostly boxed MMA fighters or faded names since turning professional.
He lost to Briton Fury in last year.
Commercial Success
However, the relative newcomer remains one of boxing's largest money-making draws, frequently receiving substantial earnings.
Prediction and Belief
The 28 year old anticipated a knockout win in the fourth or fifth round and asserted he would stop the highly-expected match between Joshua and Fury, which is apparently under discussion for two years from now.
"The next fight will be myself against Tyson Fury in the coming year," Jake Paul stated.
Size Disparity
As both boxers engaged in the traditional stare-down, with their height and weight contrast clearly visible, it emphasized just how unlikely this entire matchup is - and how amazing it is that the fight is truly happening.
