The British boxer is set to fight Jake Paul in an eight-round match which will be streamed live on the streaming platform.
Briton Joshua said he will "overwhelm entirely" the American and "overpower" the American as the combatants confronted each other to promote next month's boxing match.
Former twice world heavyweight champion Joshua battles social media star turned fighter Paul - in what is, on paper, a huge mismatch - at Miami's Kaseya Center on December 19th.
Fighter's Mentality
"I will injure his face and hurt his body. I'm here to prove I'm the better fighter," Joshua, 35, declared.
"I'll stamp all over him. That's the boxer's mindset.
"I'm going to really want to hurt him. That's my intention."
Civil Exchange
In spite of those words, a composed Joshua and social media star Paul - typically famous for his showmanship - were respectful and remained civil with each other.
Paul instead targeted ex Joshua's opponent Francis Ngannou and labeled him "ridiculous" after Ngannou turned down a bout proposal.
Targeting Fury
Joshua, in the meantime, targeted UK rival Tyson Fury - and declined a £1m bet 'The Gypsy King' claims he will make on a Paul victory.
"Jake Paul outshines Tyson Fury - he's present here," the boxer stated.
"I respect him for that."
Serious Fighter
In spite of declaring he will hurt Jake Paul, Joshua refused to talk badly about his rival's boxing ability.
"Jake is a serious fighter," he said.
Jake Paul's Background
Jake Paul - who originally gained popularity on the television network - has mostly fought MMA fighters or past-their-prime fighters since becoming pro.
He was defeated by Briton Tommy Fury in last year.
Commercial Success
Still, the novice is still one of the sport's largest money-making draws, frequently receiving massive financial rewards.
Prediction and Confidence
The 28-year-old anticipated a KO victory in the fourth or fifth round and stated he would derail the much-anticipated Fury-Joshua bout, which is allegedly being planned for 2026.
"It's going to be myself against Tyson Fury in the coming year," Jake Paul said.
Size Disparity
As both boxers met for the customary stare-down, with their height and weight contrast on show, it emphasized just how improbable this entire matchup is - and how astonishing it is that the bout is really going ahead.
