Thanks for the inspiration. I have a girl whose head becomes a sea anemone centered around a sarlaac pit that can swallow whole people (possibly cars and even building with enough willpower spent) traumatic and horrifying. That forces trauma checks, another girl who can cause any skin she's had tattooed to peel off and act like a tentacle, she gets a bunch of spider webs, tentacles, snakes and tribal lines and thorny rose bushes tattooed all over her. Seeing the muscle and sinew beneath is horrifying.
A guy who raises the dead as complete slaves with intellect sufficiently intact to speak and even teach, but they can only follow explicit orders and become violent if interrupted, any order to "act as if they weren't enslaved" results in a berserk state for a round.
I'm liking cancer, if you can think of anything that seems more "mystical" or can just reflavor some of those ideas as less "sciencey" I'd appreciate it. Like EMP guy being a human fetish so ghosts are drawn to and into him so they create magnetic disturbance.
Most characters are supposed to get their abilities when under stress, then I ask "what would they want to happen in that moment if it could be anything in the world, anything at all (sans stuff like the world blows up)." then I turn that idea into a power but it's supposed to be expressed a little more magic/horror less experiment gone wrong. Where the abilities meet modern technology can be the source of the "curse" like Medium/EMP guy.
