The British boxer will face the American YouTuber in an eight-bout contest which will be broadcast live on Netflix.
British boxer Anthony Joshua stated he will "overwhelm entirely" the American and "defeat" the American as the pair met personally to publicize next month's heavyweight fight.
Former twice unified boxing king Joshua faces social media star turned fighter Paul - in what is, on paper, a huge mismatch - at Miami venue on December 19th.
Fighter's Mentality
"I will damage his features and hurt his body. I'm here to prove I'm the better fighter," Joshua, 35 years old, declared.
"I'll stamp all over him. That's a fighter's mentality.
"I'm going to genuinely try to cause him pain. That's my goal."
Respectful Exchange
In spite of these statements, a calm Joshua and internet personality Jake Paul - typically famous for his dramatics - were respectful and remained civil with each other.
Paul rather attacked ex Joshua rival Francis Ngannou and labeled him "not serious" after the Cameroonian declined a match opportunity.
Targeting Tyson Fury
Joshua, at the same time, criticized British rival Tyson Fury - and refused a million-pound wager 'The Gypsy King' says he will place on a Paul win.
"Jake Paul is better than Fury - he's actually sitting here," Joshua said.
"I give him credit for that."
Serious Fighter
In spite of declaring he will hurt Jake Paul, Joshua declined to talk badly about his rival's fighting skills.
"Jake is a legitimate boxer," he remarked.
Paul's Background
Paul - who first rose to fame on the Disney Channel - has mainly boxed mixed martial artists or faded names since turning professional.
He was defeated by Briton Tommy Fury in last year.
Financial Success
However, the relative newcomer is still one of boxing's greatest commercial attractions, frequently receiving massive earnings.
Forecast and Confidence
The 28-year-old forecast a KO victory in round four or five and asserted he would stop the highly-expected match between Joshua and Fury, which is reportedly in the works for two years from now.
"It's going to be myself against Tyson Fury next year," Paul said.
Size Difference
As the two fighters engaged in the traditional face-off, with their physical disparity evident, it highlighted just how improbable this complete situation is - and how astonishing it is that the fight is truly going ahead.
