"You won't lay a finger on any of my students!!"
Marie Mjolnir (マリー・ミョルニル, Marī Myoruniru) was the death's weapon formerly in charge of Oceania. However, since the resurrection of Asura, her duties have since then been reassigned to Azusa. She is currently partnered with Franken Stein and is a teacher at Death Weapon Meister Academy.
Marie is a kind and genuine woman, being gentle and expressing her personality at all times as well as maintaining a kind and compassionate relationship with other people. Despite her initial reluctance to teach, she found herself enjoying not only the students when meeting some of them for the first time but later teaching as well. As a teacher, she has grown to care for students within a short amount of time, even feeling like she overstepped her boundaries as a new teacher when she attempted to prevent members of Kilik's Team from entering the Magnetic Field However, even Marie has a fierce side, disliking any student who disobeys orders (although recognizes good intentions) enough to personally call them up. She is also protective of her students and those she cared about, going so far as to attack Justin Law because of his betrayal of the DWMA, killing Joe Buttataki, and targeting her student, Maka Albarn. Of her own admittance, Marie's goal in life was to become a Death Scythe, get married, and retire straight away after for a peaceful life. Despite these claims, however, Marie herself not only actually enjoys to working but, according to both Azusa and Stein, is even obsessed with it.
Marie does come with her own flaws. With most of her previous relationships, she's admitted to going to great lengths to keep her former boyfriends happy but finds them running out on her. Azusa claimed that this resulted because of her putting to much pressure, coming off as clingy. Her desperation for marriage has even led her to want to marry someone (or something like that of a toilet) right away, in which required Azusa to talk her out of. She can also be petty and has a hard time moving on after breakups, willing to make herself pretty upon learning of her ex-boyfriend Joe's arrival in an attempt to make him feel bad for dumping her.
She holds a horrible sense of direction and has often gets lost in the Academy, even though she's been acquainted with its layout for years (even newcomers like that of Crona and Ragnarok possessed a better sense of direction compared to Marie). When confronted with facts in which she doesn't agree with, she tends to react emotionally and strike others with a simple punch, unaware of how hard her strikes tend to be. Strangely enough, her position within the Eight Mysteries of DWMA reveal that for an odd reason, she is known within the academy to destroy toilets during late nights for reasons unknown.
In her physical appearance, Marie is a young woman who possesses large, yellow eyes, and long yellow hair.
Zig-zags are prominent in Marie's appearance. She wears her hair loosely with no bangs, and it forms a zig-zag part on her head. Marie wears a black dress with a large, golden, zig-zag pattern in the front from the waist down. Parts of the dress are made of a different fabric. These parts are located on the long sleeves of the dress from the elbows down, and a part below the chest that resembles a girdle-like shape. She wears a pair of white, high-heel shoes that also appear to have a zig-zag pattern on them.
Finally, Marie's most iconic piece of clothing is her large, left eyepatch, which is decorated with a thunderbolt insignia that also appears in her Weapon form.
While hunting Justin, her clothing changed to feature a black sleeveless jacket over a shirt, shorts with patterning similar to her original dress and sandals. These clothes bear a noticeable resemblance to those worn by Joe Buttataki.

After the death of B.J., she left the DWMA with Stein in order to find Joe's murderer and also because his last request was for her to keep an eye on Stein.Maka, she charges towards him and hits him in the chest. It appears her attack has little effect but after extending part of her weapon from her fist, Justin is sent flying yet he still manages to recover in mid-air to land safely. Observing this ineffective result, Marie assumes her weapon form and both her and Stein go on the offensive. The resulting speed, caused by Marie's abilities, easily overwhelms Justin and forces him to retreat using an artifact. This leaves Marie and Stein in the desert outskirts of Death City, with nothing but the coffin Justin left behind.
After her group's infiltration of Noah's hideout, she, along with others, are quickly and violently beaten down by a combination of Noah's abilities in controlling the Book of Eibon and the power provided to him by Brew. Downed Justin Law casually walks over to her preaching some type of insane babble that could be a type of madness pray. Asking him to stop this Madness and how much can sin he can possibly live with she is quickly silenced by Justin as he strikes her face with his bladed arm. Her condition is unknown but she was seen to be alive after Spartoi escape from the book. However, after Stein and the others break free from Noah’s creatures, she seems to be unconscious as Stein holds her, possibly monitoring her condition.
After the assault against Noah's group and the damage done to her by Justin Law's vicious attack, Marie made a full recovery from the battle. However, she also arrives to inform Maka and Black☆Star that, due to Crona attacking the Eastern European Branch of the the DWMA, killing the branches Death Scythe - the Demon Cannon Ball Tsar Prushka and his partner - along with destroying a city in the Ukraine, Crona has been added to Shinigami's target list and Spartoi have been issued orders to find and execute them.
Although Free inadvertently removes Marie and her peers to the Earth, missing their return to the Moon by a significant distance, Eruka Frog is able to use her Calculation Magic to locate Asura's position in the sky to put into Stein's mind. Stein then is able to aim and throw Marie in Lightning Rope form to within striking distance of Asura. While Stein's throw fails to connect, Marie retains enough autonomy to circle back around Asura three more times to hit him directly. However, Asura knocks Marie back into the atmosphere, and it is the combined work of Sid Barett and Akane☆Hoshi, wielding Spirit Albarn and Clay Sizemore respectively, to keep her from flying away.
With her peers on the Moon's surface, Marie watches her students fight Asura. Thanks to the work of Maka and, from within Asura, Crona, Asura's Black Blood is expelled to form a barrier around the Moon to protect his exit. As Marie is still on the Moon with her peers, there is no time for Maka and her classmates to rescue Marie in time. With no hope of escape, Marie holds onto her fellow teachers and soldiers, waiting for the Black Blood to engulf her.
However, thanks to the arrival of Maba and the Witch Judge, Marie is teleported off the Moon and back to the Death Weapon Meister Academy. She is shortly reunited with Maka and her students, with Maka running up to her (and past her own father) for a hug. While Marie comments how bruised Maka is from this battle against Asura, Maka (after noticing Marie's breasts due to Crona's Madness from the Moon) can sense a second soul wavelength from Marie's body, confirming her pregnancy.
At the coronation celebrating Kid's ascension as the new Shinigami, Marie and Stein receive thanks from Kid for her work as his teacher and in hope that she will continue to be his mentor. Marie says she is confident students like Kid and Black☆Star are sufficiently powerful to face all future threats, which will be necessary for the next generation. At that moment, Kid senses Marie's pregnancy. Stein then explains that he learned Marie was pregnant with their child before Death sent them to the Moon. While Stein opposed her presence on the mission due to her pregnancy, he could not convince her otherwise. Stein has to give up cigarettes during this pregnancy, but he is pleased to have a new "guinea pig," prompting Marie's annoyance.
- Marie's name and abilities allude to frequently to Norse mythology. Her last name, "Mjolnir," alludes to Thor's hammer from Norse mythology. The hammer was one of the most powerful weapons in the world, capable of crushing almost anything. Her Triquetra Attack alludes to the Valknut, a symbol associated with Odin, Thor's father.
