Bastet

Bastet is Mariah's Stand in Stardust Crusaders, the third part of the series, and it draws its name and theme from the Egyptian goddess of the same title. It is an automatic, bound Stand shaped like an ordinary electrical outlet, trailing a cable that Mariah can fix wherever she likes. Its coloring shifts between adaptations, rendered white with yellow trim in the colored manga and yellow with green trim in the anime, while the fighting game Heritage for the Future shows a ghostly feline bust surfacing whenever Mariah guards or acts.

Bastet is built to punish curiosity rather than to fight, and on its own it can neither attack nor defend, leaving Mariah to simply hide and let a trapped victim perish. Anyone who touches the outlet receives a jolt and is transformed into a living magnet that hauls in nearby metal. The pull only grows over time, beginning with small items and escalating until objects as heavy as cars come hurtling in, threatening to bury or skewer the afflicted. Several people can be cursed at once, and they are dragged toward one another as well as toward loose metal.

The power carries real limits. Mariah must keep a certain gap between herself and her target, since drifting too far lets the magnetism fade. The effect can also rebound on her, as Joseph Joestar and Muhammad Avdol proved when they pinned her between them and let the mass of clinging metal crush her.

Mariah relies on Bastet as a pure assassination tool, staying out of sight so that nothing points back to her while her victims are slowly overwhelmed. Her chief targets are Joseph Joestar and Avdol, both turned into helpless magnets, though the pair ultimately reverse the trap and use its own escalating force against her.
