Quote1 When I was little I had a pair of red rubber boots. My boots took me places. One day they got lost. I thought they were hiding under my bed. But they're gone. I miss them. All of them. One of us is tender one of us is not. One of us take vengeance. All four tied in a knot. Quote2
-- Typhoid Mary src

Early Life

Her condition was accidentally caused by Matt Murdock, before he became Daredevil. He attacked a villain at the brothel where Mary Walker worked. To his surprise, the girls working there defended him. In a moment of panic, he lashed out against the women, knocking Mary out the window. At that moment, Mary vowed that she would never allow a man to hurt her again. She became Typhoid Mary.[7][10]


Typhoid frequently worked for the Kingpin, and often battled Daredevil.[11] During this time she had a romantic relationship with Matt Murdock.

Through hypnosis, the abnormal and psychotic personalities were suppressed from Walker's consciousness, and she began to lead a normal life, becoming an actress on a soap opera.

During the Acts of Vengeance, Doctor Doom sent her to defeat Power Pack.[12]

At one time Daredevil manipulated Typhoid into bed and tricked her into reverting to her Mary persona right before he had her taken away in a straitjacket.[13]

She has also confronted Wolverine,[14] Ghost Rider[15] and Vengeance.[16]


At one point, during a particularly bad patch in her struggle for control over her personalities, she befriended Mary Jane Watson and battled Spider-Man. As Bloody Mary once again resurfaced, she began killing men who were violent towards their domestic partners. With Spider-Man's help, she managed to regain control and voluntarily turned herself in to the police for treatment.[17]


At one point, Mary was confined to a mental institution where each personality hired a mercenary. Mary Walker hired Deadpool to kill her, Typhoid Mary hired Deadpool to break her out, and Bloody Mary hired The Vamp/Animus to break her out to resume a killing spree. Deadpool defeated the Vamp/Animus but refused to kill Mary Walker, allowing the Typhoid personality to become dominant.[18] Typhoid and Deadpool had a few adventures together, but when Deadpool pushed her out of a window, her memories of Daredevil kicking her out of the brothel window returned. She and Deadpool traveled to New York City to confront Daredevil but Deadpool became upset when he found out that she had also been killing people from her past who couldn't defend themselves against her. He and Daredevil defeated her but, against Daredevil's pleas, Deadpool insisted on trying to rehabilitate her himself. Mary however, discovered Deadpool's infatuation with Siryn and, using an Image Inducer, tricked Deadpool into sleeping with her. When Deadpool discovered the ruse, he was so shocked and betrayed that he gave up trying to help Mary. [19]

Agent of Chaos

At some point, the Kingpin fell from power and was left in a coma. He eventually recover and started gaining power again and wanted to take out his enemies. He recruited Walker to distract Daredevil. She confronted him while he was Matt Murdock and set him on fire before his bodyguards Luke Cage and Jessica Jones took her down. She was then imprisoned on the Raft.[20]

The Raft

Mary was able to escape during Electro's attack on the Raft, and began to work for the Kingpin once more.[21]


Mary was one of the few mutants to retain her powers following M-Day, but she was not initially included in the official record of the remaining mutants (the so-called "199th" still empowered mutant, or "Mutant Zero").[3]



Mutant Zero

After the events of the superhuman Civil War, Mary was found by Henry Peter Gyrich and recruited into the Initiative program. She joined because she could not control her multiple personalities. She received a pardon and an opportunity to continue to attempt to integrate her fractured mind.[2]

Mary's true identity was made classified and she adopted the alias Mutant Zero. Dr. Leonard Samson prohibited anyone from referencing any of her other identities because it could have led to a period instability. She was inducted into the black ops team, the Shadow Initiative, but was only allowed to be "activated" once per mission due to her mental instability.[3]

Later on, Taskmaster was appointed as field leader of the Shadow Initiative. He discovered Mutant Zero was Walker and analyzing her fight patterns he saw that they matched up. He shattered her helmet's faceplate and revealed her identity as Typhoid Mary. By remaining active in the field for too long, the psychological controls guiding the Mutant Zero personality failed, and Mary manifested a new independent personality which chose to abandon the Initiative.[22]


Later on Mary decided to work with Daredevil and The Hand to which she ended up fighting and burning Spider-Man. Later on when the heroes then broke into the revival of Bullseye she fought Spider-Man again and lost. In the end, it turns out that she was a sleeper agent for the Kingpin and was being controlled by him with subliminal messages.[23]


Mary later began working for Lady Deathstrike[24] and was her first recruit onto her Sisterhood of Mutants. [25]

She was also seen working with Black Cat until she was captured. While in custody, she was kept sedated to suppress her abilities.[26]

Mary also had dissociative identity disorder, causing her to have two other abnormal personalities in addition to her main, seemingly normal one. "Mary" was a demure, quiet pacifist; "Typhoid" was audacious, lustful, and vicious; and "Bloody Mary" was merciless, brutal, and hated all men. Mary occasionally manifested a fourth personality, "Walker", who acted as a moderating influence on the others.[27]


Typhoid Mary is a mutant[23] and possesses a number of powers. The effectiveness of her powers differs on which personality is in control. "Innocent Mary" and "Walker" typically has no access to her powers. Typhoid, Bloody, and Mutant Zero all access her telepathy, telekinesis, and pyrokinesis to varying degrees. Although Mary cannot access her powers, Typhoid has occasionally expressed their powers through Mary while Mary was in control, and without Mary realizing it.[5]

  • Pyrokinesis: She has the power to ignite, extinguish, and control/manipulate fire.[28]
  • Telekinesis: She can levitate small objects over short distances (such as weapons of under 10 pounds; knives, razors, etc.), making a knife spin in place or retrieving her weapons if they are dropped.[28] Her "Bloody Mary" persona often gathered and assembled small metal objects into improvised battle-armor.[17]
  • Telepathy: She can implant mental suggestions in the minds of others. She can induce sleep in weak-minded individuals and most animals, or create "sensory ghosts" as a distraction, causing people to look away because they think they saw a flash or heard a noise. Typhoid can compel people to take simple actions without thinking about it, like reaching for a blade or kissing her, letting her predict their next move or guide them into traps. She has the power to psionically seduce men, using a combination of behavioral psychology and telepathic prods to make them quickly become obsessed and fall in love with her.[28]


Mary seems to be very skilled in martial arts and the use of edged weapons.[5]


Dissociative Identity Disorder: Mary Walker had three distinct personalities. The "Mary" personality is a timid, quiet, pacifist; her "Typhoid Mary" persona is adventurous, lustful, and violent; her "Bloody Mary" personality is sadistic, brutal, and misandrist. Typhoid was so different than Mary, that even Daredevil was, at first, unable to tell they were the same person, even with his enhanced senses.[5]


As Mutant Zero, Mary is equipped with a suit of full body armor that appears to enhance her physical strength and an arsenal of weapons, including guns and various blades.[3]


Guns, swords.

  • When Mary's personality changes, her physiological traits (heart rate, respiratory pattern, scent, EKG, etc) also change. Daredevil was unable to recognize Mary and Typhoid as the same person despite his enhanced senses,[28] and even sighted people often believe the personalities are different people.[29]
