Marshall began her career in professional wrestling in 1995, accompanying her husband Steve "Mongo" McMichael to the ring in WCW.

Raised in Tuscaloosa, Alabama, Marshall became a track-runner, cheerleader, and Homecoming Queen in high school before attending the Lee Strasberg Theatre Institute in New York City.

At The Great American Bash 1996, Steve McMichael and his partner Kevin Greene competed against two of the Four Horsemen (Ric Flair and Arn Anderson).

[7][14] She would willingly take off her blouse to show the crowd her "puppies", a nickname originally bestowed upon her chest by wrestler Road Dogg and later utilized by commentator Jerry Lawler.

[16] The strategy helped Jarrett and partner Hart defeat The Big Boss Man and Ken Shamrock to become World Tag Team Champions in January 1999.

[17] In the same month, she also attempted to cause distraction in a tag match between Jarrett and Hart against Road Dogg and Billy Gunn, but was attacked by Chyna, who was also at ringside.

In February, Debra feuded with female professional wrestler Ivory, making her in-ring debut in a mixed tag match on Monday Night Raw, which ended in a no contest.

[24] Commissioner Shawn Michaels, however, ruled that he considered the woman who had lost her dress the winner, crowning Debra the new Women's Champion.

[28] On the following episode of RAW, Debra participated in an intergender tag match with Chyna against the team of Jarrett and Prichard, in a winning effort.

[21] In November 1999, Debra participated in an eight-women Sudden Death match at Survivor Series where she teamed with The Fabulous Moolah, Mae Young, and Tori in a winning effort against Ivory, Jacqueline, Luna Vachon and Terri Runnels[29] which also served as her last appearance as an in-ring performer, despite being trained at the time to compete.

[3][11] Debra resigned as Lieutenant Commissioner on the March 5, 2001 episode of Raw to pursue managing again, while it was revealed on-screen that she was the wife of Stone Cold.

Although she was advertised to be involved in the Wrestlemania 17 main event match between The Rock and Stone Cold Steve Austin, she was later pulled due to both competitors lobbying not to have her out at ringside.

[32] After Wrestlemania, she returned on an episode of RAW, questioning Vince McMahon for his role in Stone Cold's villainous persona, and subsequently slapping him after he insulted her.

On an episode of RAW, Debra was subject to a bucket of milk accidentally falling on her, which was a miscommunication by Stacy Keibler and Shawn Stasiak who meant to play the prank on Kurt Angle.

References of Debra were subsequently dropped from WWE programming and media altogether, although, in 2021, she was acknowledged by WWE.com in a list of female performers who made an impact outside the ring.

[37] Marshall's marriage to National Football League alumnus and professional wrestler Steve McMichael lasted thirteen years.

[1][2] On June 15, 2002, police responded to a call to the couple's residence in San Antonio, Texas, and found Debra with bruises and a bloody nose.

[39] He pleaded no contest on November 25 and received a year's probation, a $1,000 fine, and an order to carry out eighty hours of community service.

[40] Marshall later auctioned her wedding ring off on eBay for $27,100 and donated a portion of the proceeds to "Safe Place", an organization which assists the victims of domestic abuse.
