Anthony Joshua is set to fight the American YouTuber in an eight round fight which will be broadcast live on the streaming platform.
Briton Joshua declared he will "overwhelm entirely" the American and "break" the American as the pair met personally to publicize the upcoming heavyweight fight.
Ex twice unified boxing king Joshua meets YouTuber-turned-boxer Jake Paul - in what is, theoretically, a mammoth disparity - at Miami arena on 19 December.
Boxer's Mindset
"I will damage his features and hurt his body. I aim to demonstrate I'm superior," 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 my intention."
Civil Interaction
Despite such comments, a calm Anthony Joshua and internet personality Jake Paul - usually known for his theatrics - shared friendly words and kept it respectful with each other.
Paul rather attacked former Joshua rival Francis Ngannou and described him as "not serious" after the Cameroonian turned down a bout proposal.
Targeting Fury
Joshua, meanwhile, criticized British rival Tyson Fury - and declined a £1m bet 'Tyson Fury' says he will place on a Paul victory.
"[Paul] is superior to Fury - he showed up," the boxer said.
"I give him credit for that."
Serious Fighter
In spite of stating he plans to punish Paul, Anthony Joshua refused to talk badly about his rival's fighting skills.
"Jake is a credible opponent," he said.
Paul's History
Paul - who originally gained popularity on the Disney Channel - has primarily boxed MMA fighters or faded names since entering professional boxing.
He lost to British fighter Fury in last year.
Commercial Success
Still, the relative newcomer continues to be one of boxing's largest money-making draws, regularly earning huge financial rewards.
Forecast and Confidence
The 28 year old anticipated a stoppage in the fourth or fifth round and claimed he would stop the much-anticipated Fury-Joshua bout, which is apparently being planned for two years from now.
"It's going to be me versus Tyson Fury in the coming year," Jake Paul said.
Physical Disparity
As both boxers met for the traditional stare-down, with their physical disparity on show, it drove home just how improbable this complete situation is - and how remarkable it is that the match is actually proceeding.
