Just one other little thing, Nanomachines on the Subatomic Scale doesn't really work very well, because the line between matter and energy (and space and time, depending on the theory you believe) gets pretty blurry. Subatomic scale is basically blurring into the quantum scale. While it could be done in science fiction terms I guess, they would be operating on a completely different set of rules than normal physics, electricity, etc.
This is not "hard" science fiction, by which I mean a future we can prognosticate using scientific advances we can foresee, but not yet accomplish. I do believe that as humanity continues to expand the frontiers of scientific knowledge, many of the problems we currently see will be circumvented through unforseeable advances and discoveries, but I'm not trying to prognosticate, only to create an interesting backdrop.
This is all just background information, barely any of which will ever be explained in the story itself, and even then it will be seen only through legend and metaphor. I merely want to have a better understanding of the forces involved for my own sake as a writer so that I can make the willing suspension of disbelief easier to maintain for my readers.
There is an anime called Darker than Black (Available on netflix if you have the streaming service) where the main character has the ability to kill with electric current.
This was actually what started me thinking about electricity as a potential power. The more I think about it, the more I think the fighting style and abilities will be remarkably similar.
I also wanted to give a big thank you to everyone keeping this discussion alive. You've all been a HUGE help for me already, and while I rarely understand all the terms you're throwing around, you definitely have given me a much more distinct starting point for my own research. Thank you very much.
