The British boxer will face the American YouTuber in an eight round contest which will be shown live on Netflix.
Briton Anthony Joshua stated he will "overwhelm entirely" Jake Paul and "overpower" the American as the combatants came face-to-face to promote the upcoming boxing match.
Former two-time world title holder Joshua battles social media star turned fighter Jake Paul - in what is, by the numbers, a huge uneven pairing - at Miami arena on 19 December.
Boxer's Mentality
"I will injure his face 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 the boxer's mindset.
"I intend to seriously aim to cause him pain. That's my goal."
Respectful Exchange
In spite of those words, a composed Joshua and internet personality Paul - normally famous for his theatrics - were respectful and maintained decorum with each other.
Paul rather targeted former Joshua's opponent Francis Ngannou and called him "ridiculous" after Ngannou declined a bout proposal.
Targeting Tyson Fury
Anthony Joshua, at the same time, criticized British rival Fury - and refused a large bet 'Tyson Fury' claims he will make on a Paul victory.
"[Paul] outshines Fury - he's present here," Joshua said.
"I acknowledge that."
Legitimate Fighter
Despite declaring he will punish Paul, Joshua chose not to speak negatively about his opponent's boxing ability.
"Jake is a legitimate boxer," he stated.
Paul's Background
Paul - who originally gained popularity on the Disney Channel - has primarily fought MMA fighters or declining opponents since entering professional boxing.
He lost to Briton Tommy Fury in last year.
Financial Attraction
However, the relative newcomer is still one of boxing's largest financial successes, frequently receiving massive financial rewards.
Prediction and Confidence
The 28 year old anticipated a knockout win in round four or five and asserted he would stop the highly-expected Fury-Joshua bout, which is allegedly under discussion for 2026.
"It will be me versus Tyson Fury in the coming year," Paul declared.
Size Disparity
As Joshua and Paul participated in the customary face-off, with their size difference evident, it drove home just how improbable this complete situation is - and how remarkable it is that the bout is actually happening.
