Mike Tyson has branded Jake Paul no more than a manufactured killer as he begins to lock in for their showdown next month.

The legendary heavyweight champion is set to face YouTuber-turned-boxer Paul on November 15 in a massive heavyweight showdown after almost a year of build-up. There are massive questions around how the bout will go, particularly given that Tyson is 58-years-old.

But he has begun to open up with more training footage and interviews as the fight draws closer. And he has left a terrifying warning for the celebrity boxer in a new preview video for their Netflix pre-fight documentary series.

Jake Paul and Mike Tyson will release pre-fight Netflix Documentary

As part of the build-up for November 15, both Jake Paul and Mike Tyson will feature in a multi-part documentary series for broadcaster Netflix. It is the streamers first foray into live boxing, and there are a number of layers to the promotion.

The documentary will likely answer a number of questions that have arisen surrounding the bout, particularly since the first date for their meeting was canceled due to a medical emergency. Tyson was forced out by doctors due to an ulcer flare-up, which meant that Paul instead fought Mike Perry.

And fans will be intrigued to see how the legendary boxers camp is going after such an incident, which caused widespread criticism of the event. The documentary, entitled COUNTDOWN will be released on two dates, with episodes one and two out on November 7, and episode three out on November 12.

Mike Tyson sends frightening message to Jake Paul in Netflix preview

In the first trailer for COUNTDOWN, both Paul and Tyson can be seen training, as well as discussing the fight. One clip shows Tyson watching the YouTubers post-fight interview after stopping Perry, in which he declares that he will take his throne.

The iconic boxer laughs, before telling the cameras hes a manufactured killer, Im a natural born killer. His face very quickly changes from jovial to serious during the intense scene, which has changed fan perspective on the fight.

During an earlier segment, Tyson also notes that he needs the fear of humiliation to motivate him to do major tasks. I wont do anything if I dont risk being embarrassed, he tells the cameras. Like now, I want to fight this young motherf***er.
