Ahead of his long-awaited Octagon debut against Mickey Gall at UFC 203 next month, the fourth and final installment of his new multiple-part documentary, “The Evolution Of Punk (Ep. 4) — Cult Of Personality,” is now available for viewing.

Featured above is the complete fourth episode of the four-part special that documents the transition of CM Punk (aka Phil Brooks) from former longtime pro wrestling star and WWE Superstar to legitimate MMA fighter and UFC Superstar.

The official description for episode four of “The Evolution Of CM Punk” reads as follows:

“With an opponent named and a date set for his first fight, CM Punk possesses unprecedented motivation — but must slow his training to recover from back surgery. Punk’s opponent Mickey Gall comes face to face with the star at a UFC event.”

CM Punk vs. Mickey Gall takes place at this Saturday’s UFC 203 pay-per-view, which is headlined by Stipe Miocic’s first UFC Heavyweight Championship defense against fellow dangerous knockout artist Alistair Overeem.

UFC 203 is scheduled for Saturday, September 10, 2016 from the Quicken Loans Arena in Cleveland, Ohio, and will air exclusively on pay-per-view.
