Anthony Joshua is set to fight the American YouTuber in an eight round contest which will be shown in real-time on Netflix.
Briton Joshua said he will "overwhelm entirely" Jake Paul and "break" the American as the pair met personally to build hype for next month's bout.
Former twice unified title holder Joshua battles social media star turned fighter Paul - in what is, on paper, a huge uneven pairing - at Miami's Kaseya Center on 19 December.
Boxer's Attitude
"I will injure his face and damage his physique. I'm here to prove I'm superior," the British boxer, 35, stated.
"I will dominate him completely. That's how fighters think.
"I intend to genuinely try to injure him. That's my intention."
Respectful Exchange
In spite of such comments, a relaxed Joshua and internet personality Paul - usually known for his dramatics - shared friendly words and maintained decorum with each other.
Paul rather criticized ex Joshua rival Francis Ngannou and described him as "not serious" after the Cameroonian declined a fight offer.
Taking Aim at Tyson Fury
Joshua, at the same time, took aim at British rival Fury - and refused a million-pound wager 'Tyson Fury' says he will place on a Paul victory.
"[Paul] is superior to Fury - he showed up," Joshua stated.
"I respect him for that."
Serious Fighter
In spite of stating he plans to punish Paul, Joshua refused to speak negatively about his rival's pugilistic talent.
"Jake Paul is a credible opponent," he stated.
Paul's Background
Jake Paul - who initially became famous on the Disney Channel - has mostly boxed MMA fighters or faded names since turning professional.
He lost to Briton Tommy Fury in last year.
Financial Success
Still, the novice is still one of the sport's biggest financial successes, regularly earning huge paydays.
Prediction and Confidence
The 28-year-old anticipated a KO victory in the fourth or fifth round and claimed he would stop the long-awaited Fury-Joshua bout, which is allegedly in the works for two years from now.
"The next fight will be myself against Tyson Fury next year," Paul stated.
Size Disparity
As Joshua and Paul met for the traditional face-off, with their size difference evident, it drove home just how improbable this whole event is - and how astonishing it is that the match is really going ahead.
