Blue Mary, whose real name is Mary Ryan, debuted as a private detective in Fatal Fury 3: Road to the Final Victory. Mary grew up in a police family, and soon joined the police herself. She fell in love with a man named Butch, who worked with her father in the secret service. Butch also taught Mary a lot about Commando Sambo (her fighting style). While on a mission protecting the president, Butch and her father were both shot and killed by terrorists. The leather jacket she wears is a keepsake given to her as a gift from Butch. Mary also has a dog named Anton.

In the King of Fighters series, a mysterious benefactor requested Mary's services to enter the tournament, along with Billy Kane and Yamazaki. During the outcome of the tournament, it was discovered that Yamazaki had become more and more insane due to the Orochi blood coursing through his veins and that Billy was sent by Geese to keep an eye on him in order to learn the secret of the Orochi power. However, during a moment of confusion, Yamazaki escaped and Mary was left to ponder on Geese's motives and the root of the situation.

Following its conclusion, Terry Bogard informs her of the NESTS cartel and their actions occurring in Southtown. With a new goal in mind to stop the organization, Mary joins the Women's Team along with King, Kasumi Todoh, and Xiangfei, and the "Lonely Wolves" in 2000 and 2001 to assist in stopping NESTS in the following tournaments, eventually leading to its demise. Around this time, it is rumored that she fell in love with Terry. It is unknown whether she finally hooked up with Terry or not.

In 2003, she joins the tournament to investigate the movements of Those From the Past and teams up with former teammate King, as well as another Fatal Fury Team alumna Mai Shiranui. In KOF XI, Mary teamed up with Vanessa and Ramon to continue her case.

When compared to many other fighting game babes, one could say Blue Mary is of the "plain" variety (when it comes to looks). No, her outfit isn't bad... but it can be called generic. I find her Real Bout outfit (with the vest) a lot cooler than her typical KOF get-up... but still, her appearance is kinda plain. I can admit there's something cool about her though. Although her Commando Sambo based fighting style is different & pretty unique, it isn't what I'd call incredible either. She's got a few cool  moves & throws, but many KOF characters outshine her. On a side note, I find it funny how some artists draw her with a huge belt, while others draw her with a normal-sized belt. I personally think she looks cooler & more original with the oversized belt... it's one of the more prominent parts of her visual design when it comes down to it, might as well make it big! lol. In fairness, I think SNK could bring her back and make her a more interesting design if they chose. I'd actually like to see how she'd look in the KOF XIII style.
