The British boxer will face the American YouTuber in an eight round fight which will be broadcast live on Netflix.
British boxer Joshua declared he will "overwhelm entirely" the American and "break" his opponent as the two fighters confronted each other to build hype for the upcoming bout.
Former two time unified heavyweight champion Joshua battles social media star turned fighter Paul - in what is, theoretically, a massive mismatch - at Miami's venue on 19 December.
Boxer's Attitude
"I will damage his features and damage his physique. I'm here to prove I'm the better fighter," Joshua, 35 years old, declared.
"I plan to overwhelm him. That's how fighters think.
"I'm going to genuinely try to injure him. That's my goal."
Respectful Interaction
In spite of such comments, a calm Joshua and internet personality Jake Paul - usually recognized for his showmanship - shared friendly words and maintained decorum with each other.
Jake Paul rather attacked former Joshua's rival Francis Ngannou and described him as "a joke" after the Cameroonian turned down a match opportunity.
Taking Aim at Fury
Joshua, in the meantime, targeted British rival Tyson Fury - and declined a million-pound wager 'The Gypsy King' claims he will make on a Paul win.
"Jake Paul is better than Tyson Fury - he's actually sitting here," Joshua stated.
"I acknowledge that."
Serious Fighter
Despite stating he plans to punish Paul, Anthony Joshua declined to comment unfavorably about his opponent's boxing ability.
"Jake Paul is a legitimate boxer," he said.
Jake Paul's History
Jake Paul - who originally gained popularity on the television network - has mostly boxed MMA fighters or past-their-prime fighters since entering professional boxing.
He lost to Briton Fury in last year.
Commercial Attraction
However, the relative newcomer is still one of the sport's greatest financial successes, consistently making substantial financial rewards.
Prediction and Belief
The 28 year old forecast a KO victory in round four or five and claimed he would prevent the much-anticipated match between Joshua and Fury, which is allegedly in the works for two years from now.
"It will be my match with Fury next year," Jake Paul stated.
Physical Disparity
As Joshua and Paul participated in the usual face-off, with their height and weight contrast evident, it drove home just how improbable this whole event is - and how amazing it is that the match is really proceeding.
