The British boxer is set to fight Jake Paul in an eight-bout match which will be broadcast in real-time on the streaming platform.
British boxer Anthony Joshua declared he will "dominate completely" the American and "break" his opponent as the two fighters met personally to promote next month's bout.
Former two-time unified heavyweight champion Joshua faces social media star turned fighter Paul - in what is, theoretically, a massive disparity - at Miami's venue on 19 December.
Boxer's Mentality
"I'm going to damage his features and hurt his body. My goal is to show I'm superior," the British boxer, 35 years old, stated.
"I will dominate him completely. That's the boxer's mindset.
"I intend to genuinely try to injure him. That's my intention."
Respectful Interaction
Despite these statements, a calm Anthony Joshua and internet personality Paul - normally known for his theatrics - were respectful and kept it respectful with each other.
Jake Paul instead attacked ex Joshua rival the Cameroonian fighter and called him "a joke" after Ngannou turned down a bout proposal.
Taking Aim at Tyson Fury
Anthony Joshua, meanwhile, targeted British rival Fury - and rejected a large bet 'The Gypsy King' states he will put on a Paul victory.
"[Paul] is superior to Fury - he showed up," Joshua commented.
"I give him credit for that."
Serious Fighter
Despite declaring he will punish Paul, Anthony Joshua chose not to comment unfavorably about his rival's boxing ability.
"Jake Paul is a credible opponent," he stated.
Jake Paul's History
Paul - who initially became famous on the Disney Channel - has primarily fought MMA fighters or declining opponents since entering professional boxing.
He lost to British fighter Tommy Fury in last year.
Commercial Success
Nevertheless, the novice continues to be one of the sport's greatest money-making draws, frequently receiving huge financial rewards.
Prediction and Confidence
The 28-year-old predicted a knockout win in rounds four or five and stated he would derail the highly-expected Fury-Joshua bout, which is apparently in the works for two years from now.
"It will be myself against Tyson Fury in the coming year," Jake Paul declared.
Physical Disparity
As both boxers participated in the usual confrontation, with their physical disparity evident, it highlighted just how improbable this complete situation is - and how remarkable it is that the fight is really proceeding.
