Anthony Joshua will face the American YouTuber in an eight round contest which will be streamed live on the streaming platform.
British boxer Joshua said he will "dominate completely" the American and "overpower" his opponent as the two fighters came face-to-face to publicize the upcoming boxing match.
Ex two-time unified boxing king Anthony Joshua meets social media star turned fighter Jake Paul - in what is, on paper, a massive disparity - at Miami's arena on 19 December.
Fighter's Mentality
"I'm going to break his face and break his body up. I'm here to prove I'm superior," the British boxer, 35 years old, declared.
"I plan to overwhelm him. That's a fighter's mentality.
"I will seriously aim to injure him. That's what I want to do."
Respectful Interaction
In spite of these statements, a calm Joshua and social media star Paul - normally known for his dramatics - exchanged pleasantries and maintained decorum with each other.
Jake Paul instead criticized former Joshua rival Francis Ngannou and described him as "a joke" after Ngannou turned down a fight offer.
Taking Aim at Tyson Fury
Anthony Joshua, meanwhile, criticized UK opponent Fury - and refused a million-pound wager 'The Gypsy King' states he will put on a Paul victory.
"Jake Paul outshines Tyson Fury - he's actually sitting here," Joshua commented.
"I acknowledge that."
Serious Fighter
Despite saying he intends to damage his opponent, Joshua chose not to speak negatively about his opponent's fighting skills.
"Jake Paul is a credible opponent," he remarked.
Jake Paul's Background
Jake Paul - who initially became famous on the Disney Channel - has primarily fought MMA fighters or past-their-prime fighters since turning professional.
He lost to British fighter Tommy Fury in last year.
Commercial Success
Nevertheless, the inexperienced fighter continues to be one of boxing's biggest commercial attractions, consistently making substantial earnings.
Prediction and Belief
The 28-year-old anticipated a KO victory in round four or five and claimed he would prevent the long-awaited match between Joshua and Fury, which is apparently being planned for two years from now.
"It's going to be myself against Tyson Fury next year," Jake Paul said.
Size Difference
As Joshua and Paul met for the customary stare-down, with their size difference clearly visible, it drove home just how surprising this whole event is - and how amazing it is that the match is really going ahead.
