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. Despite her outfit being rather revealing, she somehow conceals an impressive arsenal of bolts, screws, knives and other objects to throw at her magnetized victims.

Mariah comes off as a calm, cool-headed person. This might be a facade however, as she easily loses her cool whenever things don't go according to plan. She is subject to contorting her face and biting her lip comedically when she is upset or uncomfortable. She also possesses a very distinct laugh, an act she often performs whenever she has her opponents helplessly trapped in the magnetic power of her Stand. 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 Avdol 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 Avdol 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 is unable to fight anymore because of her broken bones.

JoJo's Bizarre Adventure (SNES Game)
Mariah is one of the boss enemies on the game. The events from BAST appears on the game with one difference detail, instead of fighting alone, Mariah attacks both Joseph Joestar and Avdol alongside with Hol Horse.

JoJo's Bizarre Adventure: Heritage for the Future (PS1/DC/Arcade Game)
Mariah makes her palayble appareance on the Capcom game, she was included on the second version of the game (Jojo's Venture). She appears as a playable character with an style based on ranged traps, most of which were taken from her fight against Joseph and Avdol.

Her game style is focused on middle-long range, keeping the enemy away with her moveset. Even without an active stand, her Bast no Jiryoku, when is activated, instead of summoning Bast, she will place an magnetism-trap on the screen (allways near her), if the opponent gets hit by this trap, his "magnetism" level will rise 1 level (with 5 being the maximum), making all Mariah's attack stronger. She's one of the only characters in the game to fight on a middle-long range, the other main being Hol Horse.

Most of her moveset is based on the objects she used on the fight against Joseph and Avdol, such as knives, forks and electrifying energy cables. Her first super move makes she uses the magnetism on the opponent's to atract screws hidden on her bra and damage the enemy, her second super move makes she uses an rising uppercut one the opponent, launching him/her into the air and attracting a lot of metal objects causing massive damage, ending by an car smashing the opponent (the same car that caused her defeat on the story).

Along with Midler, they are the only playable women characters in the game. Mariah is also one of the special characters in the game that do not turn into a child when hit by Alessi's stand, instead she turns into the old woman that Joseph encounters after her skirt buttons fly up.

Trivia

 * She is subject to some extremely comedic facial expressions when she is irritated, both in the manga and in Heritage for the Future when the Timer runs out and she has less health than her opponent.
