Mariah is a villainess who first appeared in Jojo's Bizarre Adventure Volume 21, Chapter 199. In Stardust Crusaders, Mariah magnetizes
Avdol with her Stand, Bastet, 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 Avdol and Joseph run over by a train and even electrocuted. However, the two manage to outsmart her by
maneuvering her in between them and then having their metal-cluttered bodies slam into her, fracturing all the segments of her bones in her body and deactivating her Stand. She is later hospitalized and is unable to fight anymore because of her broken bones.
