Anthony Joshua will face Jake Paul in an eight round contest which will be shown live on the streaming platform.
British boxer Joshua declared he will "overwhelm entirely" the American and "defeat" his opponent as the combatants confronted each other to promote the upcoming bout.
Former two time world title holder Joshua faces social media star turned fighter Jake Paul - in what is, theoretically, a mammoth disparity - at Miami arena on 19 December.
Fighter's Mindset
"I will damage his features and break his body up. I'm here to prove my superiority," the British boxer, 35, said.
"I will dominate him completely. That's the boxer's mindset.
"I will seriously aim to hurt him. That's what I want to do."
Civil Interaction
In spite of those words, a composed Joshua and internet personality Jake Paul - normally recognized for his dramatics - 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 rejected a fight offer.
Taking Aim at Fury
Joshua, at the same time, took aim at British opponent Tyson Fury - and refused a £1m bet 'The Gypsy King' claims he will make on a victory for Paul.
"[Paul] outshines Fury - he's present here," Joshua said.
"I give him credit for that."
Legitimate Opponent
In spite of stating he plans to punish Paul, Joshua declined to talk badly about his opponent's pugilistic talent.
"Jake is a credible opponent," he stated.
Jake Paul's Background
Paul - who first rose to fame on the Disney Channel - has mainly fought MMA fighters or past-their-prime fighters since turning professional.
He lost to Briton Tommy Fury in last year.
Commercial Success
However, the relative newcomer remains one of boxing's largest financial successes, frequently receiving huge financial rewards.
Forecast and Confidence
The 28 year old predicted a knockout win in round four or five and claimed he would prevent the much-anticipated match between Joshua and Fury, which is apparently being planned for 2026.
"It's going to be my match with Fury next year," Jake Paul declared.
Size Difference
As Joshua and Paul participated in the traditional face-off, with their size difference on show, it drove home just how surprising this complete situation is - and how astonishing it is that the match is actually happening.
