This is awesome! So, I'm gonna have to go with my darling thief Rat. She does have this weird thing where she, um, can eat batteries (yes, and gain their power) and she destroys electric-based hardware around her? Like, sitting by a computer would give her a headache, and if she just has this weird sixth seek-and-destroy sense; she feels relief and gets a brief boost of energy. It's an electro-medical anomaly, like a bizarre new anti-mechanical antibody, and I'd love to see how you explain it!
Okay, this is super creative and I have toyed with the idea of an electricity manipulator before but could never come up with anything fake-science sounding BUT ANYWAY
In the SOLE universe this would probably manifest as the ability to siphon the power and electricity out of technology in order to manipulate it herself. Obviously this makes it very hard to record her abilities, since she tends to suck the life out of cameras. (Incidentally, this greatly contributed to how she broke out of the labs, if she were to do so)
So it would be less of a physically eating batteries (since I think that’s what you were saying?) and more of a rendering-these-batteries-useless.
Anyway, she’d be able to suck the electricity out of all our tech and then manipulate it for her own gain. Whether this means zapping someone a la Thor, or shorting out an entire block of technology, is up to her.
Rat sounds like a Tier Three to me, btw, on this tier system.
Tell me what powers you think Agau would design your OC with, and I’ll give you a bunch of details about it!
