Anthony Joshua is set to fight the American YouTuber in an eight-bout fight which will be streamed live on Netflix.
Briton Joshua declared he will "stamp all over" the American and "break" his opponent as the pair confronted each other to build hype for the upcoming boxing match.
Ex two time unified boxing king Joshua battles YouTuber-turned-boxer Jake Paul - in what is, theoretically, a massive uneven pairing - at Miami's venue on 19 December.
Fighter's Attitude
"I'm going to injure his face and hurt his body. I'm here to prove I'm superior," Joshua, 35, said.
"I plan to overwhelm him. That's the boxer's mindset.
"I intend to genuinely try to cause him pain. That's my goal."
Respectful Interaction
In spite of these statements, a composed Joshua and internet personality Paul - normally famous for his theatrics - were respectful and kept it respectful with each other.
Jake Paul rather criticized ex Joshua's rival Francis Ngannou and labeled him "ridiculous" after the Cameroonian declined a bout proposal.
Taking Aim at Tyson Fury
Anthony Joshua, meanwhile, took aim at British rival Fury - and rejected a large bet 'Tyson Fury' claims he will make on a victory for Paul.
"[Paul] is superior to Tyson Fury - he showed up," the boxer said.
"I acknowledge that."
Serious Fighter
In spite of saying he intends to damage his opponent, Joshua chose not to talk badly about his rival's pugilistic talent.
"Jake is a serious fighter," he said.
Jake Paul's History
Jake Paul - who first rose to fame on the Disney Channel - has mostly boxed MMA fighters or declining opponents since turning professional.
He was defeated by British fighter Fury in last year.
Commercial Attraction
Still, the novice remains one of boxing's biggest financial successes, consistently making huge earnings.
Forecast and Confidence
The 28-year-old predicted a knockout win in rounds four or five and asserted he would stop the highly-expected match between Joshua and Fury, which is apparently in the works for two years from now.
"It's going to be myself against Tyson Fury next year," Jake Paul declared.
Size Difference
As the two fighters met for the customary face-off, with their physical disparity on show, it emphasized just how unlikely this entire matchup is - and how remarkable it is that the fight is actually happening.
