Mariah

Mariah (マライヤ Maraiya) is a minor antagonist appearing in Part III: Stardust Crusaders.

Appearance/Personality
Mariah appears as a long-legged woman in a miniskirt and a hood. She wears white gloves, tights, and black leather shoes. She collects screws and bolts as projectiles that launch themselves at her magnetized victims.

Mariah comes off as a calm, cool-headed person. However, when her plans are somehow thwarted, she becomes mad and bites her lip and tongue, making angry faces. Mariah also seems to demonstrate either some degree of promiscuity or attraction towards older men, as she mentions that Joseph is very sexy and that she would have been his lover if it were not for Dio Brando being more attractive.

Stardust Crusaders
Mariah magnetizes Joseph Joestar and Mohammed Abdul with her stand, attracting metal upon them and even into each other, giving them all sorts of difficulties. During a very powerful display of tactics, she attempts to get Mohammed Abdul and Joseph Joestar run over by a train and even electrocuted. However, the two managed to outsmart her by maneuvering her in between them, and then having their metal-cluttered bodies slam into her, breaking her bones and deactivating her stand. She is later hospitalized and can't fight anymore because of her broken bones.

Steel Ball Run
She appears in Steel Ball Run as Lady Luck, her alternative counterpart. In it she appeared with black hair instead of light blue hair. Mariah appeared with Gyro when he was renowned medical doctor. Mariah is not a stand user but she now has the ability to transform into an old woman and back again. Lady Luck is an old girlfriend of Gyro, because Gyro uses his spin on the steel ball to tickle her.

Trivia

 * Mariah is one of the special characters in Heritage for the Future that do not turn into a child when hit by Alessi's stand, turning to the old woman that Joseph encounters after her skirt buttons fly up.
