Fatal Fury

Her former lover, Butch, and her father have worked together as fellow colleagues in the secret service. While on a mission protecting the president, they are both shot and killed by terrorists. Devastated by the loss, it is said she has never smiled again since the incident. The leather jacket she wears is a keepsake given to her as a gift from Butch.

Having been taught by her former lover how to fight, she becomes a freelancer. Throughout the series, she takes on various odd jobs to investigate mysterious cases. During this time, she meets Terry and the two become good friends.

The King of Fighters

In this series, her work was far from over. One day, a benefactor requested her services to enter the King of Fighters tournament, along with Billy 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 Li Xiangfei, and the "Lonely Wolves" in 2000 and 2001 to assist in stopping NESTS in the following tournaments, eventually leading to its demise.

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 Team Fatal Fury alumna Mai Shiranui. In KOF XI, Mary teamed up with Ramon and Vanessa to continue her case.


Blue Mary is very friendly towards everyone, but she knows (or thinks) that her job must come first before everything else. Mary developed a strong bond with Terry, they seem to have a genuine care and fondness with each other.
