:"My name is Zak Bagans. I've never believed in ghosts until I came face to face with one. So I set out on a quest to capture what I once saw onto video....With no big camera crews following us around, I am joined only by my fellow investigator Nick Groff and our equipment tech Aaron Goodwin. The three of us will travel to some of the most highly active paranormal locations, where we will spend an entire night, being locked down from dusk until dawn....Raw...Extreme...These are our Ghost Adventures."

Being a former skeptic himself, Bagans says that his passion for investigating the paranormal resulted from a face-to-face encounter with the spirit of a suicidal woman who haunted his old apartment building in Trenton, Michigan. Afterward, his life-changing experience caused him to actively pursue capturing video evidence of the afterlife. In the introduction of each episode, Bagans states:

Using a self-described religious, scientific, and emotional approach, Bagans is known and criticized for his aggressive and confrontational methods used during investigations; however, he maintains that he respects the afterlife and only provokes evil entities in order to elicit responses. In a June 2009 interview with the Paranormal Underground magazine, he stated, "I don't want the public perceiving us as the taunting, provocative ghost hunters. We do that only to the bad spirits who we know are attacking the living." Bagans also mentions this concept in various interviews and episodes throughout the series.

In season 3, Bagans summarized his greatest fears while climbing an aged staircase inside a shot tower at the Remington Arms factory: "Heights, snakes, and crazy-looking dolls...Those are on Zak’s top three I-don’t-like list." Zak encountered situations involving these fears in the episodes at Sloss Furnaces, Idaho State Penitentiary, and the Riddle House, respectively.
