Anthony Joshua prepares to battle Jake Paul in an eight-round contest which will be streamed 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 the upcoming heavyweight fight.
Former two-time unified boxing king Joshua meets social media star turned fighter Paul - in what is, by the numbers, a huge disparity - at Miami's venue on 19 December.
Boxer's Mindset
"I plan to break his face and break his body up. My goal is to show my superiority," the British boxer, 35, said.
"I plan to overwhelm him. That's how fighters think.
"I intend to seriously aim to hurt him. That's my intention."
Respectful Interaction
In spite of such comments, a composed Anthony Joshua and internet personality Jake Paul - normally famous for his theatrics - shared friendly words and kept it respectful with each other.
Jake Paul instead attacked ex Joshua's opponent the Cameroonian fighter and called him "a joke" after the Cameroonian turned down a fight offer.
Targeting Tyson Fury
Joshua, in the meantime, took aim at British opponent Fury - and refused a £1m bet 'The Gypsy King' claims he will make on a Paul win.
"[Paul] is better than Fury - he showed up," Joshua stated.
"I respect him for that."
Serious Fighter
Despite saying he intends to punish Paul, Anthony Joshua chose not to comment unfavorably about his rival's pugilistic talent.
"Jake Paul is a serious fighter," he stated.
Paul's History
Paul - who first rose to fame on the Disney Channel - has mostly fought mixed martial artists or past-their-prime fighters since entering professional boxing.
He lost to Briton Tommy Fury in last year.
Financial Success
Still, the relative newcomer continues to be one of boxing's largest financial successes, frequently receiving huge paydays.
Forecast and Confidence
The 28 year old forecast a KO victory in rounds four or five and claimed he would prevent the highly-expected match between Joshua and Fury, which is apparently under discussion for two years from now.
"It will be my match with Fury in the coming year," Paul stated.
Physical Difference
As Joshua and Paul met for the traditional stare-down, with their height and weight contrast evident, it emphasized just how surprising this complete situation is - and how amazing it is that the fight is really proceeding.
