The British boxer will face the American YouTuber in an eight-bout match which will be shown in real-time on Netflix.
British boxer Joshua declared he will "overwhelm entirely" the American and "defeat" the American as the pair met personally to build hype for next month's boxing match.
Ex two time world boxing king Joshua faces YouTuber-turned-boxer Jake Paul - in what is, theoretically, a massive 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 the better fighter," Joshua, 35, declared.
"I will dominate him completely. That's the boxer's mindset.
"I will seriously aim to injure him. That's my intention."
Civil Exchange
Despite these statements, a calm Anthony Joshua and internet personality Jake Paul - typically known for his dramatics - were respectful and kept it respectful with each other.
Jake Paul rather criticized former Joshua opponent Francis Ngannou and called him "not serious" after Ngannou declined a match opportunity.
Targeting Fury
Anthony Joshua, meanwhile, criticized UK rival Fury - and refused a £1m bet 'Tyson Fury' states he will put on a victory for Paul.
"[Paul] is superior to Tyson Fury - he's actually sitting here," the boxer stated.
"I respect him for that."
Serious Opponent
In spite of saying he intends to hurt Jake Paul, Joshua declined to talk badly about his opponent's fighting skills.
"Jake Paul is a serious fighter," he said.
Paul's History
Paul - who originally gained popularity on the Disney Channel - has primarily fought MMA fighters or faded names since becoming pro.
He was defeated by British fighter Fury in last year.
Commercial Attraction
Nevertheless, the novice is still one of boxing's largest commercial attractions, consistently making substantial paydays.
Forecast and Belief
The 28 year old predicted a KO victory in rounds four or five and claimed he would stop the highly-expected match between Joshua and Fury, which is apparently being planned for two years from now.
"The next fight will be my match with Fury in the coming year," Jake Paul declared.
Size Disparity
As both boxers participated in the usual face-off, with their height and weight contrast evident, it emphasized just how surprising this whole event is - and how remarkable it is that the fight is really proceeding.
