how much metal do the different Perrine iterations contain? asking because it occurred to me that she and Orietta are both pathfinder characters(different editions though iirc) and that while they're in different worlds, it would be funny if they met and Orietta could detect her with her at-will Detect Metal(not actually sure if it works like that but imo it should be able detect metal in/composing people)
Ooh, that's a fun question!
So, Perrine Sideris, the Pathfinder iteration of Perrine from Molthune is an Aphorite (with baseline human ancestry) rather than an android, so she's the least metal of them all, HOWEVER she still has more metal than the average person owing to the fact that the bodies of Aphorites are often inundated with crystalline and metallic traces/dust (specifically metallic black hair and silvery motes in her skin in her case), so it would still give her away I'd say! She's also a Psychic too so I'd imagine she has a pretty unique magical trace too if she were to use Detect Magic instead.
Regular android Perrine, indeterminate though her setting may be, is of course wholly artificial and thus absolutely inundated with metal. She's taken great care to get as authentic looking synthetic silicon skin as possible, but underneath that it's still all machinery; no bio-components or anything like that, so she'd be incredibly easy to pick out.
Starfinder Perrine would be a similar story because she's not actually an "Android" as defined by that race in SF, but specifically a Sentient Robotic Organism which has drastically altered her form to appear humanoid. I've never cared much for how weirdly contrived the baseline PF/SF androids were and find SROs way more interesting.
