The British boxer is set to fight the American YouTuber in an eight-round contest which will be shown live on Netflix.
British boxer Anthony Joshua said he will "dominate completely" the American and "defeat" his opponent as the pair met personally to promote next month's boxing match.
Ex two-time world heavyweight champion Anthony Joshua battles YouTuber-turned-boxer Paul - in what is, theoretically, a massive disparity - at Miami's Kaseya Center on 19 December.
Fighter's Mentality
"I plan to damage his features and break his body up. I'm here to prove I'm superior," the British boxer, 35 years old, declared.
"I'll stamp all over him. That's how fighters think.
"I'm going to seriously aim to injure him. That's my goal."
Civil Interaction
Despite those words, a calm Joshua and social media star Paul - usually known for his dramatics - were respectful and remained civil with each other.
Jake Paul rather targeted former Joshua's rival Francis Ngannou and described him as "ridiculous" after the Cameroonian turned down a fight offer.
Targeting Fury
Anthony Joshua, in the meantime, took aim at UK rival Fury - and refused a £1m bet 'Tyson Fury' says he will place on a Paul victory.
"[Paul] outshines Tyson Fury - he's present here," Joshua stated.
"I give him credit for that."
Serious Opponent
Despite stating he plans to damage his opponent, Joshua chose not to talk badly about his opponent's fighting skills.
"Jake Paul is a legitimate boxer," he said.
Jake Paul's History
Jake Paul - who first rose to fame on the television network - has mainly boxed mixed martial artists or past-their-prime fighters since entering professional boxing.
He lost to Briton Fury in last year.
Financial Attraction
Nevertheless, the novice remains one of boxing's greatest commercial attractions, consistently making substantial financial rewards.
Prediction and Belief
The 28 year old forecast a knockout win in the fourth or fifth round and stated he would derail the long-awaited match between Joshua and Fury, which is allegedly being planned for two years from now.
"It will be me versus Tyson Fury next year," Paul declared.
Physical Difference
As Joshua and Paul engaged in the customary face-off, with their size difference clearly visible, it highlighted just how surprising this whole event is - and how amazing it is that the match is actually happening.
