Marie is the main antagonist of Skullgirls, appearing in every character's Story Mode (often as the final boss) and in the ninth round of Arcade mode. She was the second possible DLC character to be revealed in the Indiegogo campaign, at $40,000. It has been stated that she is one of the characters who would need to be made playable for the canon Skullgirls storyline to be revealed. Her homestage is Final Atrium, transformed from the catacombs of the Grand Cathedral.
She became the Skullgirl in late summer, meaning she has been the Skullgirl for the past few months, as the game takes place in autumn. She is currently in the "middle stages" of the transformation process of becoming a Skullgirl.
She wears a maid uniform that she found in the manor that served as the makeshift orphanage she and Patricia lived in. By wearing it, she appeared more grown up and the other orphans listened to her more.
Marie plays the piano. On the Skullgirls Original Soundtrack image Marie is shown doing a recital.
Marie Korbel, also known as Bloody Marie (JP: ブラッディー・マリー), is the current Skullgirl.
