Torn between electric and light, but I'd have to go with light.*
   I could move electrons with it, exciting them to higher shells,
   causing the ability to control electricity as well. I could also
   use it to excite wood to make it burn, or change the perception
   of objects (including myself) to disappear. I could also convert
   matter into energy through excitement of electrons to a fast
   enough speed (so far, light's got the max-speed thing going
   right now.. Having control of light would also give me control
   of magnetism as well and of course colors and invisibility...
   but yeah, I guess I just wanna disappear sometimes :P unless we
   got some neutrinos... I'd really like a neutrino sword.. then I
   could pass through matter entirely undetectably... but that's
   rarely an option in elemental lists. PLUS, I wouldn't be able to
   pick it up! damn. But when playing random roleplay stuff with my
   nephew, when he'd ask, "What elemental do you want?" I usually
   end up choosing Ice, just for the challenge of it and being able
   to put out fire, turn into water... and buy myself some time by
   freezing enemies :P** hehe
