The British boxer is set to fight the American YouTuber in an eight-round contest which will be streamed in real-time on the streaming platform.
Briton Anthony Joshua said he will "dominate completely" Jake Paul and "break" the American as the two fighters confronted each other to build hype for next month's bout.
Ex two-time unified title holder Anthony Joshua meets social media star turned fighter Jake Paul - in what is, by the numbers, a massive uneven pairing - at Miami's arena on 19 December.
Boxer's Mentality
"I'm going to injure his face and hurt his body. I'm here to prove my superiority," Joshua, 35, said.
"I plan to overwhelm him. That's the boxer's mindset.
"I will seriously aim to hurt him. That's what I want to do."
Civil Exchange
In spite of those words, a calm Anthony Joshua and internet personality Paul - normally known for his dramatics - shared friendly words and kept it respectful with each other.
Jake Paul instead criticized ex Joshua's opponent the Cameroonian fighter and called him "not serious" after Ngannou turned down a bout proposal.
Targeting Fury
Joshua, meanwhile, criticized British rival Fury - and rejected a £1m bet 'Tyson Fury' states he will put on a Paul win.
"[Paul] outshines Tyson Fury - he's present here," the boxer stated.
"I respect him for that."
Legitimate Opponent
Despite declaring he will damage his opponent, Anthony Joshua refused to talk badly about his opponent's fighting skills.
"Jake is a credible opponent," he said.
Jake Paul's Background
Paul - who first rose to fame on the Disney Channel - has primarily fought MMA fighters or declining opponents since entering professional boxing.
He was defeated by British fighter Fury in last year.
Commercial Success
Still, the novice is still one of boxing's largest money-making draws, consistently making huge financial rewards.
Forecast and Belief
The 28-year-old anticipated a stoppage in the fourth or fifth round and claimed he would stop the highly-expected Fury-Joshua bout, which is reportedly being planned for 2026.
"It's going to be my match with Fury in the coming year," Jake Paul said.
Physical Disparity
As Joshua and Paul engaged in the usual confrontation, with their physical disparity evident, it highlighted just how improbable this whole event is - and how remarkable it is that the fight is truly happening.
