A new OC, based slightly off of an older one... meet Auriga. She was originally an energy-based being of enormous power (like all the inhabitants of her planet), but she decided to convert her energy into a physical body and live like a human... for some reason.
While most of her energy went toward creating a material body, she still maintains enough excess energy to manipulate electrical machinery. For this reason she's hailed as a gifted repair technician for all machines, big and small, simple and complex (and considered a veritable miracle-worker by those who don't know her background). I imagine robots and other cognitive machines would view her as a sort of saintly figure, and go on pilgrimages in hopes of meeting her...
Perhaps because of her special communion with machines, she's a bit uncomfortable around humans and other biological, extraterrestrial species; she has a way of sticking her foot in her mouth at the worse of times and just isn't good at connecting with others.
