The British boxer is set to fight the American YouTuber in an eight round fight which will be streamed in real-time on Netflix.
British boxer Joshua said he will "dominate completely" the American and "break" the American as the two fighters came face-to-face to promote next month's heavyweight fight.
Former two-time world title holder Joshua meets social media star turned fighter Paul - in what is, by the numbers, a huge mismatch - at Miami's arena on 19 December.
Fighter's Mentality
"I plan to damage his features and damage his physique. My goal is to show I'm superior," Joshua, 35 years old, declared.
"I will dominate him completely. That's the boxer's mindset.
"I intend to really want to cause him pain. That's my goal."
Civil Interaction
Despite those words, a calm Joshua and internet personality Jake Paul - typically recognized for his showmanship - were respectful and maintained decorum with each other.
Jake Paul rather criticized ex Joshua rival Francis Ngannou and called him "a joke" after the Cameroonian rejected a match opportunity.
Taking Aim at Tyson Fury
Anthony Joshua, in the meantime, took aim at UK opponent Fury - and refused a large bet 'Tyson Fury' says he will place on a Paul win.
"[Paul] is superior to Tyson Fury - he showed up," Joshua commented.
"I give him credit for that."
Legitimate Fighter
Despite stating he plans to hurt Jake Paul, Anthony Joshua declined to talk badly about his opponent's pugilistic talent.
"Jake Paul is a serious fighter," he stated.
Jake Paul's History
Jake Paul - who originally gained popularity on the television network - has primarily boxed MMA fighters or declining opponents since entering professional boxing.
He was defeated by British fighter Tommy Fury in last year.
Financial Success
However, the inexperienced fighter remains one of the sport's largest money-making draws, consistently making huge earnings.
Prediction and Belief
The 28-year-old predicted a knockout win in rounds four or five and asserted he would derail the highly-expected Fury-Joshua bout, which is reportedly being planned for two years from now.
"The next fight will be me versus Tyson Fury next year," Paul declared.
Physical Disparity
As the two fighters met for the usual face-off, with their size difference evident, it drove home just how improbable this complete situation is - and how amazing it is that the bout is really going ahead.
