Anthony Joshua is set to fight the American YouTuber in an eight-bout match which will be shown in real-time on the streaming platform.
British boxer Joshua said he will "overwhelm entirely" Jake Paul and "defeat" his opponent as the two fighters came face-to-face to publicize the upcoming bout.
Former two time world title holder Joshua meets YouTuber-turned-boxer Jake Paul - in what is, by the numbers, a mammoth mismatch - at Miami's Kaseya Center on 19 December.
"I'm going to break his face and damage his physique. I'm here to prove I'm the better fighter," the British boxer, 35 years old, said.
"I will dominate him completely. That's the boxer's mindset.
"I intend to really want to injure him. That's my intention."
Despite those words, a relaxed Anthony Joshua and social media star Paul - typically known for his showmanship - exchanged pleasantries and kept it respectful with each other.
Jake Paul instead criticized ex Joshua's rival Francis Ngannou and called him "a joke" after Ngannou declined a bout proposal.
Anthony Joshua, meanwhile, took aim at British opponent Fury - and refused a large bet 'Tyson Fury' claims he will make on a victory for Paul.
"Jake Paul is superior to Fury - he showed up," the boxer commented.
"I respect him for that."
Despite stating he plans to damage his opponent, Joshua declined to speak negatively about his opponent's fighting skills.
"Jake Paul is a serious fighter," he stated.
Paul - who originally gained popularity on the television network - has mostly fought MMA fighters or declining opponents since turning professional.
He was defeated by Briton Tommy Fury in last year.
Still, the inexperienced fighter is still one of boxing's biggest money-making draws, regularly earning huge paydays.
The 28 year old predicted a stoppage in round four or five and claimed he would prevent the highly-expected Fury-Joshua bout, which is apparently being planned for 2026.
"It's going to be my match with Fury next year," Jake Paul said.
As Joshua and Paul engaged in the usual confrontation, with their physical disparity evident, it emphasized just how unlikely this entire matchup is - and how astonishing it is that the bout is truly going ahead.
