Anthony Joshua is set to fight Jake Paul in an eight-round match which will be streamed live on Netflix.
Briton Joshua said he will "overwhelm entirely" Jake Paul and "break" his opponent as the pair met personally to promote next month's boxing match.
Ex two-time world title holder Anthony Joshua faces social media star turned fighter Paul - in what is, theoretically, a mammoth disparity - at Miami's Kaseya Center on 19 December.
"I'm going to break his face and damage his physique. I'm here to prove my superiority," Joshua, 35 years old, declared.
"I will dominate him completely. That's the boxer's mindset.
"I intend to really want to injure him. That's my intention."
In spite of such comments, a relaxed Anthony Joshua and social media star Paul - normally recognized for his dramatics - were respectful and kept it respectful with each other.
Jake Paul instead attacked ex Joshua opponent Francis Ngannou and described him as "ridiculous" after the Cameroonian rejected a bout proposal.
Joshua, in the meantime, targeted British rival Tyson Fury - and rejected a £1m bet 'Tyson Fury' says he will place on a victory for Paul.
"Jake Paul outshines Tyson Fury - he's actually sitting here," Joshua stated.
"I acknowledge that."
Despite stating he plans to punish Paul, Joshua refused to speak negatively about his rival's pugilistic talent.
"Jake is a legitimate boxer," he said.
Paul - who initially became famous on the Disney Channel - has primarily boxed mixed martial artists or past-their-prime fighters since becoming pro.
He lost to British fighter Fury in last year.
However, the inexperienced fighter continues to be one of boxing's largest money-making draws, regularly earning substantial paydays.
The 28-year-old anticipated a knockout win in the fourth or fifth round and asserted he would stop the much-anticipated Joshua–Fury fight, which is allegedly under discussion for 2026.
"It's going to be me versus Tyson Fury in the coming year," Paul said.
As Joshua and Paul engaged in the traditional confrontation, with their physical disparity on show, it drove home just how surprising this whole event is - and how astonishing it is that the match is actually happening.
