Anthony Joshua is set to fight Jake Paul in an eight-bout fight which will be broadcast in real-time on the streaming platform.
British boxer Joshua said he will "dominate completely" the American and "break" his opponent as the pair came face-to-face to promote next month's bout.
Former two time unified boxing king Joshua battles YouTuber-turned-boxer Paul - in what is, theoretically, a huge mismatch - at Miami Kaseya Center on 19 December.
Boxer's Mindset
"I plan to damage his features and break his body up. My goal is to show I'm the better fighter," Joshua, 35 years old, said.
"I plan to overwhelm him. That's a fighter's mentality.
"I intend to seriously aim to cause him pain. That's what I want to do."
Civil Interaction
In spite of those words, a calm Anthony Joshua and social media star Paul - usually known for his dramatics - shared friendly words and remained civil with each other.
Jake Paul instead attacked ex Joshua rival the Cameroonian fighter and labeled him "ridiculous" after the Cameroonian turned down a match opportunity.
Taking Aim at Tyson Fury
Joshua, at the same time, targeted UK rival Fury - and rejected a million-pound wager 'Tyson Fury' claims he will make on a victory for Paul.
"[Paul] is better than Fury - he's present here," Joshua said.
"I give him credit for that."
Serious Fighter
Despite declaring he will hurt Jake Paul, Joshua refused to talk badly about his opponent's fighting skills.
"Jake Paul is a serious fighter," he said.
Jake Paul's Background
Jake Paul - who initially became famous on the television network - has primarily boxed mixed martial artists or faded names since becoming pro.
He was defeated by British fighter Tommy Fury in last year.
Financial Success
However, the novice is still one of boxing's greatest commercial attractions, regularly earning huge paydays.
Forecast and Belief
The 28 year old anticipated a knockout win in round four or five and claimed he would derail the much-anticipated match between Joshua and Fury, which is reportedly being planned for two years from now.
"The next fight will be myself against Tyson Fury in the coming year," Paul said.
Size Disparity
As both boxers participated in the customary confrontation, with their physical disparity evident, it emphasized just how surprising this entire matchup is - and how astonishing it is that the match is really happening.
