The British boxer will face the American YouTuber in an eight-round contest which will be broadcast in real-time on Netflix.
Briton Joshua stated he will "dominate completely" the American and "overpower" his opponent as the combatants met personally to promote next month's heavyweight fight.
Ex two time world heavyweight champion Anthony Joshua battles YouTuber-turned-boxer Paul - in what is, by the numbers, a massive uneven pairing - at Miami arena on 19 December.
Boxer's Mindset
"I will injure his face and hurt his body. I'm here to prove I'm the better fighter," the British boxer, 35, said.
"I plan to overwhelm him. That's how fighters think.
"I'm going to really want to cause him pain. That's my goal."
Respectful Exchange
In spite of those words, a calm Joshua and social media star Jake Paul - normally known for his showmanship - shared friendly words and kept it respectful with each other.
Jake Paul instead attacked former Joshua opponent the Cameroonian fighter and called him "ridiculous" after Ngannou rejected a match opportunity.
Targeting Fury
Joshua, in the meantime, criticized British opponent Tyson Fury - and rejected a £1m bet 'Tyson Fury' says he will place on a Paul win.
"Jake Paul is superior to Fury - he showed up," Joshua commented.
"I respect him for that."
Serious Fighter
Despite saying he intends to punish Paul, Joshua declined to speak negatively about his rival's fighting skills.
"Jake Paul is a legitimate boxer," he stated.
Jake Paul's History
Paul - who initially became famous on the television network - has primarily boxed MMA fighters or declining opponents since becoming pro.
He was defeated by British fighter Tommy Fury in last year.
Commercial Attraction
Nevertheless, the novice continues to be one of the sport's greatest financial successes, consistently making massive financial rewards.
Forecast and Belief
The 28-year-old predicted a knockout win in round four or five and asserted he would derail the long-awaited Fury-Joshua bout, which is reportedly being planned for two years from now.
"It's going to be my match with Fury next year," Paul declared.
Physical Disparity
As Joshua and Paul met for the customary face-off, with their size difference evident, it drove home just how unlikely this whole event is - and how amazing it is that the bout is actually going ahead.
